Which 2-stroke oil is safest for your small engine? Temperature testing 6 of the most popular oils!

Hey everyone!
I'm excited to show you my latest temperature testing video. This time, I test 6 of the most popular 2-stroke mix oils in my Stihl leaf blower. I conduct a total of 12 temperature tests.
6 oils tested, 50:1 mix using 91 octane ethanol-free fuel.
- Amsoil Saber
- Stihl Premium
- Stihl Ultra Synthetic
- Husqvarna XP+
- Echo Red Armor
- Echo Powerblend Gold
2 exhaust (muffler) temperature readings per oil, one after 5 minutes of idle, and one after 3 minutes of full throttle. 10 minutes of cool down time between different fuels.
Why 5 minutes of idle?
-5 minutes of idle is plenty of time for whatever remaining fuel from the previous test to be drawn through the fuel lines, through the carburetor, and consumed by the engine. This gives an ample amount of time to ensure that the temperature measurement after 5 minutes is only as a result from the mixed fuel that is burned and currently in the tank.
Why 3 minutes of full throttle?
- 3 minutes of full throttle (full load) allows the engine to settle at a maximum operating temperature where the differences in temperature readings between the different brands of oils can only be effected by the cooling and lubricating properties of each oil.
Let me know what you think of the results!
Cheers!!!

I recommend the Echo Red Armor

[@johnbuck6685]

Just get any of the maxima oils and be done with it

[@Carlos.Rivera]

Which one you recommend? Link will be appreciated

[@andrewchernenkoff2611]

Maxima are good oils for sure but the saber was actuaslly supposed to be used at 100:1 which no other oil in those tests can do. Also the heat ids within spec of the engine and a couple of degrees isnt saying anything as the oil is to lubricate the piston, rings and bearings of the engine. All those other opils including Maxima, tends to leave some carbon deposits an d scoring and doesnt lubricate and engine better than Saber Amsoils does. Lubrication is what the oil is for, not keeping it a few degrees less in temperatures, lol.

[@joepiker]

Very interesting...I have been running the Husqvarna XP oil, exclusively, for a long time, maybe 20 years in professional chainsaws ( Stihl, Huskie) and professional weedwhacker/brushcutters,,Always use 89 octane, California fuel. Never had a single problem with it...Never wore out an engine , Probably they are all good as long as you remember to mix in the oil!

[@sundogtune]

well my dad has a 40 year old echo backpack blower and it still works just fine. he used EVERY type of oil you could think of in it. i also have a 25 year old hus.145 bt and just llike the echo have used all kinds of different oils in it and it STILL STARTS ON THE SECOND PULL! just bought a new hus. 570 bts ( wanted the job done quicker, 1.5 acres, i also do 2 other lots, cause i am a nice guy , lol, older ladys). seems to me it is MORE ABOUT HOW PEOPLE TAKE CARE OF THEIR EQUIPMENT THAN WHAT OIL IS BEING USED. i always lean towards using a SLIGHTLY richer mix. 1/32 to 1/16 oz. per mix more. depernding on the machine. that little bit means MUCH LONGER LONGEVITY OF THE MACHINE!! JUST MY 2 CENTS WORTH

[@NordicDan]

I run the AMSOIL Saber in all my 2-stroke stuff at a ratio of 90:1. I have a Husqvarna blower that calls for 50:1, my old Ryobi string trimmer (with interchangeable tools, one of which is a lightweight tiller that I use a lot in the early spring and late fall) that's 32:1 and my 1972 Homelite 150A that I restored which uses 16:1. All three of these get the AMSOIL mix and run beautifully, and have noticeably more power with this versus the cheap 2stroke Walmart oil I had to use once in a pinch, and the Castor 927 that I've used for years up until I switched to AMSOIL. Most impressive was my old chainsaw which I ran through its paces last weekend and it didn't even flinch. Something I did not do was do any temperature comparisons between the Castor, the AMSOIL, and the cheap Wally oil. So this video was an interesting one to see. I'm surprised the AMSOIL (given the mix ratio you used being consistent through all oils) ran the hottest. I could see it running hotter when going off the recommended mix ratio, given there's so much more gasoline going through the combustion cycle than with other ratios, but again, surprised to see it running hotter with consistent ratios. Great work!

I've used nothing but the husqvarna brand in my 323l string trimmer. Bought it brand new in 2005 and it still runs like new. I like hooskvarna!

[@halcampbell1384]

For your next test, run the same test but with a 40:1 mixture. It will really be interesting to see how much cooler the engine runs under this condition.

[@miloskovacevic2311]

40:1 will have less fuel and would probably be hotter. Because actualy it’s leaner mixture. But we’ll see if this gets tested.

[@kellybuzzelljr.3439]

Agreed - he just did a 25:1 vs 50:1 and more lubricatation = less gasoline making it's way into the cylinder. This does stand to ask though: If you're trying to be super safe and go with a 40:1 or even a 25:1 BUT you open-up your High and Low Needle Valves to get back to that perfect 14.7:1 Air/Fuel mixture, do you accomplish both goals? Less Temperature AND More Lubrication?? 🤔 Makes me wonder...

[@jeremydawkins8399]

@@miloskovacevic2311 40:1 versus 50:1 is a minuscule amount of fuel and will not really affect mixture but it makes a massive improvement on longevity of the saws internals. 50:1 is recommended only to satisfy the EPA not for the health or performance of the engine.

[@garrettstevensen2467]

@@kellybuzzelljr.3439 While he previously did test at 50:1 and then 25:1, he didn't retune the saw, in the older video. Ask ANYONE that mills for a living, and they all run at either 16:1, 25:1 or 30:1. I've never heard of anyone milling wood with a chainsaw, at 50:1...

I use Amsoil Saber Professional at 100 to1. There is no carbon, no smoke from my two-cycle equipment. I use it in non-ethanol gasoline. I have no issues. I liked your test.

The Husqvarna was my dad's saw, & I don't know what he used before he gave it to me 10 years ago. I would rather run a 40:1 mix of cheap 2-stroke oil over any of the oils tested with a higher ratio. My stuff may smoke a bit more than some, but I've also never had to replace a 2-stroke piece of equipment.. My previous 2.5 acre home was mostly woods.

[@laserflexr6321]

I guess the moral of this whole "which oil" question is which is a lot less important consideration than if. In case that was a little too cryptic, it dont matter much which oil, but never forget oil. I never put gasoline in my mix tank unless I have the proper dose of oil in hand and add it right on the fuel island. Let the gas pump measure exactly 1 gallon (the pumps are routinely tested to make sure they are metering properly) is close enough. With all the different 2 cycles I've had over the years, all but the first one of which I still have, never have I had an engine failure. Used lots of oils but mostly brand names, and mostly Stihl. it is accumulation of other broken/worn parts that cause it to be parked. I've never put a new plug in any of them. I finally lost count of the carb kits I've done, lots before I discovered NO ETHANOL. Put the walbro spiral in my saw last carb rebuild last spring, so far it runs like a champ! Keep your trimmer line soaking water in a plastic coffee can and you will have a lot less string issues from jambed heads and the line lasts a LOT longer. I'm tired of the stank of Stihl Ultra and I finally had to clean the spark arrestor screen on my 094r line trimmer this year (6yrs?). BTW I know lots say it's a bad idea but about the only time I'm at full throttle is with a blower, and occasionally with my saw, part throttle and cold running are known risk factors for carbon buildup leading to clogged screens, so I was expecting the clogged screen eventually. 10 minutes and a propane torch once every 6 years is not too bad. Leaning heavy toward Saber and would already be running it if it was on the shelf locally. I'm out of the last batch of Ultra so it is time to switch. So I am back to listening to what you all prefer.

[@AnarchAngel1]

​​@@laserflexr6321 It does matter. I wouldn't use any oil that isn't FD rated in stuff personally. Try finding a rating for the cheap super tech stuff. Order some Saber. I run it 80:1 in all my saws and it works absolutely fine. It burns super clean at lean ratios like that. It lubricates well and it's clean. Can't ask for much more. I like the way XP+ smells better but that's a small thing. Either one of those oils has never let me down

[@TsunauticusIV]

I was an OG Banshee owner. Ran nothing but Klotz and Golden Spectro through my banshee for YEARS. I raced that bike hard. Did hill climbs. Did woods racing so much that I’d melt plastic impellers regularly. Finally a compa started making metal impellers and that saved the day. Oh and water wetter too. But even with all the abuse I put my Banshee through… wear was never an issue. I tore it down when it was 10 years old to do a power build. It didn’t even need rebuilt yet. Still had great compression. I was a little nervous on the teardown because everyone was starting to hate on Klotz and that was what I ran every other tank. I rotated oils. Did Klotz one mix and then Golden Spectro the next. Not sure why I did that but I did. Anyway, I tee the engine down and there was no wear at all. Crank and pins and bore looked amazing. Piston and rings were golden too. I was impressed. I rebuilt it and sold that bike not long after. I miss it. Keep riding that banshee for me! 🙏

[@runtimmytimer]

It’s one data point about the oil’s flash point. While important, I think it’s more important to know how much oil is on internal parts. There’s other videos that do tear downs of the engine to inspect the internals which I think is far more valuable for determining which oil is “best”.

[@mikefisc9989]

I have to agree. As an owner of several Stihl products the one concern I have with Stihl HP Ultra is that it is not JASO-FD rated. Mixed at 50:1 it has been shown, through testing, to be inadequate in lubricating the upper cylinder. It is too bad that Stihl HP Super, which is JASO-FD rated, is not available in the US. Unfortunately, I believe this may be due to EPA regs.

[@andrewchernenkoff2611]

I fully agree, the engines were run in the specs of the engines ability and a few degrees difference is nothing. Oil is used to lubricate the rings, pistons, cylinders and bearings. Also, the oils should have all been run at the manufacturers recommended ratios. Amsoil Saber is supposed to be run at 100:1 and its flash point is far superior to a lot of those others and will also protect the internals of the engine better than any other oil in that test, they do the testing all the time. Im sorry testing temps is nothing and doesnt compare the oils for what they are manufacturered to do, and thst is lubricate and engine preventing wear!

I really like the husky oil. I just had to slip a new ring in my 55 husky and it looked new still inside. Very minimal carbon build and just clean. Back up to 170 compression and runs great!

Good testing with interesting results. I would like to see the same test in warmer ambient temperatures and see how that would effect the engine temperatures.

Neat test. I've ran the Amsoil Saber in my MS251 with good results since I bought it new back in 2015. Though I've kind of cherished the one quart bottle I bought as it's hard to come by. I still have enough left for mixing two or three gallons of fuel. The store I originally bought my bottle from no longer has it as they're having a hard time getting it supposedly. One of the other stores I shop at frequently sells Amsoil's two other pre-mix oils I'm going to test. According to Amsoil's own website they support the same oil qualifications as Saber does for hand held power equipment. They're just not directly advertised for use in power equipment. I've read a lot of positive reviews of people using Interceptor and Dominator in their equipment as well as their dirt bikes so I have a quart of each to test. Those are both in store so I'm testing out what can be easily grabbed off shelf before I resort to ordering off the internet. :)

Think of a welding bead and how doing a slight side to side movement while welding allows the metal on each side to cool enough to help prevent burn through.

By reading exhaust temperature, is a good indicator of fuel combustion rates, not necessarily the anti wear quality of the mixture. Crankcase lubrication, and piston wear would determine the oil’s ability to lubricant. It is my opinion, that a slightly richer mixture of oil-to- fuel ratio would extend the service life of 2-stroke engines. Non ethanol fuel @ 89 octane, with 40:1 mixture of synthetic oil. I have a brand favorite but, that’s not as important as the mixture ratio.

[@redlywaxer]

I read that Amsoil 100:1 was tested at 200:1 during development with good results. Hence when I use it, I mix it at 100:1 for a blower or trimmer, and maybe 80:1 for a saw if I'm working it hard. Always ethanol-free gasoline, and I've never had a clogged exhaust or failed carburetor or bad fuel lines. I'm still using some equipment I've had for 20+ years! Well...

[@halflife82]

Been a small engine mechanic for many many years and rebuild a lot of small engines, landscaping equipment, dirt bike engines & even RC airplane gassers included. None of the oils you tested outperform Redline Racing oil for ring & cylinder cleanliness & possibly longevity. None. The large ester base-stock they use removes contaminants much better and lubricates in extreme temp conditions (like lean runs on our RC engines) much better than other oil too. Now I haven’t thoroughly tested the Husky or Echo brands, but the others I sure have. I can speak from many many years of experience. I used to be 100% all in on Stihl Ultra Premium oil for small engines until I started noticing a trend in my own personal engines during rebuilds; way too carboned up. For example, we retune these gas 2T gas RC carbs on every single use, unlike the landscaping equipment which the needles are rarely ever touched. Even then, too much carbon buildup over time, unless ran extremely rich & under low stress/load conditions to continually wash out the combustion chamber. Ever since switching to Redline, my engines, and the rebuilds I do for customers have noticed a massive difference in consistent running due to lack of carbon buildup. The top-ends look nearly new! I’ve never gotten the hours on any engine that we get from Redline synthetic oil. There’s a reason even Desert Aircraft (DA) now only warranty their engines & military drone engines when used with Redline Racing oil. No one has more rebuild data than those guys. Period. 👍 All these oils are great and beat the Dino oils of yesteryear, but a couple of them are still the reigning champs. An no, I have affiliation with Redline but the results have spoken for themselves in my own experience of small engines. Thanks again for a great video. I’ve always been curious in exhaust temps between the brands. Head temp data above the exhaust port or under the plug via telemetry sensor would be the way I would have done it as some oils extract head heat better than others, but should show-up in exhaust temps like you’re doing here. Thanks again!

I use regular grade ethanol gas with marine stabil added for all my 2 cycle equipment. Just fired up one of my Stihl saws that has been sitting for about 3 years with old fuel mix in it. Cranked and runs well with no carb problems. I usually have some fuel mix that is a year or more old and never have any problems. Type of oil I have been using is a no name synthetic multi purpose oil mixed at recommended ratios. In 30 years of using saws, weed trimmers and even a Suzuki LJ20 2 stroke jeep I have never had any failures whatsoever using cheap oil as long as I mix it according to manufacturers recommendations. I use saws regularly and do not consider myself a novice. With all that said, i do believe the oils you tested are very good oils, and there are several others out there like Honda HP2, schaeffer's, Maxima, etc. That are really good as well.

I wonder if ambient air temperature has any effect on the temperature readings, colder air is more dense, would influence the combustion Temps in my opinion, but all in all, a very well conducted test

nice job. personally i use red line synthetic 2-stroke oil in my chainsaws.

[@theslingandjacket2337]

Interesting test but there are quite a few other variables that should be considered before drawing any conclusions from your test and that coolest oil equals the safest oil. The question you actually answered was what is the muffler / exhaust temp of a given oil blended at 50:1 with a fixed fuel to air ratio (i.e. the same carburetor setting). This tells us very little about a given two stroke oil’s lubrication and anti-wear performance. Each of these oil blends likely has a slight difference in viscosity. This in turn affects mix viscosity and the fuel to air ratio of the charge going into the engine if the carburetor settings remained constant for all samples. The fuel to air ratio directly affects the exhaust gas temp to a large degree and it takes relatively small changes in the mix viscosity and air temps to vary the fuel to air ratio. For this test to give conclusive results, the fuel to air ratio and the oil to fuel blend ratio (the mix) would both have to be held consistent. This in turn would tell which oil actually results in the coolest muffler temps. Does this leaf blower have a catalytic muffler? If so, that would also another variable affecting the exhaust temps as excess oil in the exhaust gas burning off in the catalyst would cause an increase in muffler/exhaust temp not related to internal friction of the engine components. The amount of excess oil in the exhaust would be a variable affected by the exact properties of each oil. The real purpose of the oil is to lubricant which in turn reduces wear of engine components. Just because one oil give a cooler muffler temperature at a fixed fuel to air ratio doesn’t really mean anything in terms of that oil’s lubrication, anti-wear, or deposit formation performance.

[@jameshegeman5660]

I second this comment. It was a nice thought for a video, and I appreciate the effort it took to run all of those tests, but at the end of the day these small temperature differences don’t really tell you anything at all about how the oils are doing at protecting components.

[@VoxVeritatisOne]

If temperature is your sole metric for success, you need to control for changes in ambient temperature as well. Assuming the requisite drop in temp as you burned daylight, Amsoil had a distinct advantage over all the others, especially compared to the Echo-branded oils which were disadvantaged by the presumably highest ambient temps at the time they were tested. (I don't work for any oil companies or any of the brands mentioned.) Given the 74K views, it was probably worth your time anyway.

[@cs967]

Great job Dave. Would love to see how Redline would compare. Maybe consider a similar test with some of the popular synthetic fuels...Stihl Motomix, Trufuel, etc. When I ran Motomix in my planes, the exhaust was far cleaner and cylinder temps notably cooler. Would be a pricey test, but would be interesting especially against a gasoline control.

[@dennisyoung4631]

Good to know that. I bought some for testing on a (two stroke) DC. generator, and added a small amount (10-12 cc) of silver bottle Stihl oil, as the Zenoah desires rather more oil than 50:1.

[@DavesSmallEngines]

Interesting. Maybe it really doesn’t make much of a difference after all!

[@cogentdynamics]

The outboard isn’t a great analog as the infinite water source provides a regulated and stable coolant temperatures. Air cooled high powered 2 strokes are harder on oil and lubricant performance and even necessitates different manufacturing clearances. Having said that, none of these companies refine and blend oil. We are witnessing more marketing than science.

The Saber is not prediluted so it's not really right for two cycle oil injection systems tho, it's all oil. We used to run AMSOIL 100 to 1 in our full mod race snowmobiles at between 60 & 80 to 1 ratio with up to 116 research octane race fuel, worked great. Have used it at 100 to 1 in many small two cycle engines. Spark plugs & spark arrestors stay clean, I've seldom ever replaced spark plugs. I had to finally replace the plug in my 20 year old el cheapo string trimmer, it shorted internally but still looked great. Heck some loggers out west tested it and it worked at a 200 to 1 ratio.

[@jameshegeman5660]

I appreciate the effort that Dave put into making this video, and I really like Dave’s channel. However, I have to say that I’m not sure these results mean anything at all. There are so many factors with oil properties that I don’t think minor temperature differences in the exhaust tell you anything at all about how well the oil is performing at its primary job of preventing wear. For instance - in the previous “50:1 vs. 25:1” video, the richer fuel ran hotter… but that’s not a surprise at all, since the viscosity will be greater. It doesn’t automatically imply that 25:1 is “worse” for engine lifetime. Yes - there is a difference between, say, 400° and 600°, but not between 510° and 540°. That would be my main criticism: that exhaust temp ≠ anti-wear performance. As a secondary comment, I would note that even in the cold, leaving fuel exposed in an open container is going to result in some evaporation, especially since this test took place over some time. Therefore the later mixes will have been slightly richer than ones that were tested earlier. Sorry to have to write such a negative comment. I am a subscriber and like Dave’s videos!

[@shannonwhitaker9630]

I like this test. It’s a great place to start so that more “experiments” can be conducted and compared. Given enough experiment data we will eventually reach the holy grail of the “Safest” and “Best” oil that is to be used exclusively by all.

[@michaelfarrell6448]

A lil ir temp gun trick i use is to get a sheet of aluminum foil and put it in front of exhaust in this case then temp the foil to get a air temp reading make sure you set the emissivity on ir gun and i do a few control temp reading with any ir gun i have to determine exact emissivity setting

[@brokenujoints3811]

Brp (ski doo), amsoil, polaris, cat..etc...any of the snowmobile 2 stroke oils and youll never go wrong. They make turbo 2 strokes of near 200 stock hp in sleds thrive so good enough for small stuff. I personally use the Bombardier mineral oil (50 bucks or so, 4 liters, synthetic is more) in all my old professional McCulloch chainsaws, one going back to 1971. Never even foul a plug. Pretty much 40:1 mix with no ethanol premium.

[@em4703]

Coolest doesn't mean safest. A higher viscosity oil or more oil will run slightly hotter (and statistically safer), due to residual friction and mass of oil that has to be moved around. That being said I'm not an amsoil fanboy, I run motul 800 offroad as my main oil due to being the one that gave me the best condition of p/c on my chainsaw mill after 1000 hours of runtime on a new set of piston and cylinder compared to 5 other arboristsite loved oils I tried

[@chriscalderin6677]

I could be wrong but I do not think exhaust temperature is a good indicator of the oil protecting the engine! Also a thicker film of oil left behind could raise the temperature of tool as moving fluids do heat up! So a higher temperature could mean the tool is better protected?

[@jacklabloom635]

The temperature variations results are statistically insignificant as relating to engine longevity. Basically, all of those oils work as intended. If mixed at correct fuel to oil ratios, most brands of two-cycle oils for small engines will protect small two stroke engines. I have two stroke engines that are over twenty-years old that start up every spring and run fine. One is an old Poulan chainsaw that has had different brand oils used in it over the years, usually the cheapest brand I can find at Walmart, Lowes, or Home Depot. Leaf blowers and weed trimmers typically run for extended periods of time wide open throttle. I mix fuel 40 to one in these type engines. My large chainsaws run a 25:1 mix. My smaller saws run a 40:1 mix. In over forty years, I have never had a small engine failure due to which type oil I used. The key to small engine longevity is proper fuel/oil ratio mixing, air filter and oil filter maintenance, keeping cylinder head cooling fins free of dirt and sawdust, and using ethanol free gasoline with stabilizer added, if fuel is stored for more than 30 days. Never store small engines long term ( months or years )with fuel left in the carburetor or fuel tank. Ethanol fuel is the big NO-no for small engines. If left in the carburetor, it will turn into a gel and plug up the small jets, rust the fuel bowl.

[@AnarchAngel1]

You don't need to mix at 25:1 in any saw with quality oil man. You might be doing more harm than good at that point. Choose one and run it at 40:1. Hell I run Saber at 80:1 in ALL my saws and it does absolutely fine

[@laserflexr6321]

I wish you would have drained the remaining fuel into the measuring cups to see if there was any significant difference in fuel consumption. My guess is the difference would be minor but a test would have been proof. Another thing that might be interesting is and could still be done after the fact would be some RPM comparasins each vid clip one after the other of startup in idle condition, startup while full throttle, and say 1 minute in in each condition to show differences in how it runs on each fuel mix. What made me think of that is the difference in how it accelerated and stabilized when started at full throttle. It is hard to argue with a good old fashioned drag race comparasin. Thanks for doing the tests and publishing your results I know you spent a chunk of change and all day doing it.

[@DaveBennett]

Great video and thank you for doing this comparison.

[@rottiejakeluke]

I appreciate your video, not sure if the results relay point out anything which would be meaningful to me. As the day went on the ambient t temperature of colder as the sun dropped which may or may not made a difference. Also it cannot be said if the engine’s storage of heat after time affects the cool down differently. Jerusalem.There was not any super drastic difference which , not me, would say any one brand was junk, nor was any one brand so outrageously better. I feel if an operator uses any of these “brand” oils correctly then it would be just fine. Me personally I have used both the Stihl oils, the Echo Red Armour, and the Amsoil Saber. I like the Amsoil because of the actual metallurgical data and the ability to use at 100:1. To date since changing to the Amsoil Options my equipment rums like a top answer I am saving money. I, just for grins, have looked into the cylinders of some of my equipment that I have used Amsoil in from day one and the metal looks new. Regardless, thank you for your video. I would be interested in what you feel about the outcome of the experiment and also for what other viewers felt about the results as it meant to them.

[@Gordon_L]

[@jameshegeman5660]

I would be careful of drawing any conclusions from temperature differences for fuel mixes of different viscosities. I would *expect* 40:1 to run a few degrees hotter than 50:1, since it’s more viscous. That doesn’t mean that 50:1 is “better” for your engine; probably the opposite.

[@danm8662]

I could not decide which oil to use, so I mixed them all of them together in the same can of gas.....the blower runs great!

[@absolutenigma]

I guess the only suggestion I would have would be to get the temp of the cylinder head at the spark plug rather than the exhaust. a temp sensor and readout could be obtained from any go kart racing supplier as that's what we always watch on 2 stroke karts. I think cylinder head temp would be more indicative of what's going on in the engine rather than the sheet metal muffler. Those temps could be influenced by a breeze blowing against the engine .

Interesting video. Good effort on trying to keep consistency. Obviously too much heat is bad but what if the warmer ones were actually getting more complete combustion? Could that make them hotter? I myself have beaten my head against the wall researching and watching these videos (the reason I am here). I have seen the videos Richard Flagg puts out. The scoring with Ultra looks concerning however the very Interesting thing is the lack of oil in the bottom end. I run echo red armor in my stuff that is OEM newer equipment Husky 545, echo cs310 and echo string trimmer. My Holzfforma saws all run the stihl ultra @ 25:1. I want to get rid of it all and will not run it in my nicer equipment. Alot has to do with the lack of color it has but also nervous because of what I have seen. I recently took the top end off the Holzfforma g372 just because and it looked brand new on the piston and cylinder. There was a ton of oil in the bottom end and there was not a lot of carbon up top mostly running ultra 25:1. Also no screen in the Chinese saw. Plus it has been run slightly rich as well. Good video thank you.

[@carlmiller1034]

Hey Dave, By measuring the exhuast temperature, aren't the results just providing an indication of how the fuel burns in that set-up? Was there a hypothesis being tested (i.e. lower exhaust temperature means better or "safer" oil used in the fuel.) Statistically, there is only one set of data, with zero degrees of freedom. So the results really can't be looked at with any degrees of confidence. I think so long as the oil additives meet certain industrial standards, they most likely are all adequate. There can be so much variability with the condition of the equipment and how the equipment is used. I tend to lean towards using a quality (meets a Standard) full synthetic 2-cycle oil and mix the gas at 48:1 just to error on the side of always having enough oil in the gas. I also think using ethanol-free gas is just as important as using a quality oil. Thanks for sharing. I enjoyed the video very much.

[@shannonwhitaker9630]

I agree on using Non-E fuel and a rated quality oil but the difference between 48:1 (2.66oz/gal)and 50:1 (2.56oz/gal) is negligible. If one wanted to error on the “safe side” a ratio of 40-42:1 seems more realistic. We are literally talking about a tablespoon or so more oil per gallon. I run all my modern “50:1” engines at 42.5:1 or 3oz/gal. My old steel sleeve engines are run at 32:1 or 4oz/gal.

[@laserflexr6321]

@@shannonwhitaker9630 I agree about the difference between 48 or 50:1 how clogged the air filter is makes a lot more difference in how much oil is going in the engine than that as does needle settings.

I have to say that exhaust temperature especially measured from outside, (and possibly too far away with IR gun) doesn't have almost anything to do with how good the oil is. If someone wants to optimize longevity of metal parts, just jet it a bit richer and maybe use a little bit more oil in the mix. Sacrifice is less power and maybe more carbon in the engine. Here are some interesting ideas to test instead (if not already done): -Oil amount inside 2t crankcase with different oils (compare to the flash point in the data sheet) -Oil amount inside 2t crankcase with different mixes. (Use same oil) -Torture test of 2t engine jetted properly with as little oil in the mix as possible. 0.7%, 0,5%, 0.3%? Maybe no one did this before and would make good half educational content. -Carbon cleaning abilities of different oils. -Carbon fouling tendency vs. Oil mix. -etc. I will go check some of your other videos in case you did something similar already.
