Will 4-stroke oil damage a 2-stroke engine? Let's find out!

Will 4-stroke oil in 2-stroke engine cause damage? We tested the ability of 4-stroke oil to mix with gasoline, took before and after looks at the cylinder wall inside of 2 different engines. Additionally, we performed compression testing and measured engine temperature, using 2-stroke oil as our baseline.

Don't know if you're interested, but when I was a kid lots of people told me that twostroke oil would settle out. So I mixed up a batch, sealed it up in a pickle jar and put it on a shelf in my mother's garage. After a week there was no settling, I figured the question was answered and I forgot all about it. 20 years later I was cleaning out her garage and came across that pickle jar. Still perfectly mixed. No settling at all.

In 1979 I purchased a brand new Chrysler 115 hp outboard motor. It used surface gap spark plugs and it was recommended by the manufacturer to use type TC-W 2 stroke motor oil. It was not oil injected. At this time TC-W oil was very hard to find. I reached out to a friend who was a reliability engineer for the United States Coast Guard to see what he would recommend. Surprisingly, he recommended Shell Rotella 15W-40. I decided to use it. I kept that engine for 14 years and it was running perfectly with over 4600 hours on it when I sold it. The one and only thing I ever had to repair on that engine was to replace the fuel pump. When I sold it, it still had it's original spark plugs. Chrysler said the expected life of this motor was 1500 hours. Thought you would like to know that. Love your videos. Keep them coming.

When I was a kid in the late 70’s I had a 1976 yamaha YZ80. I can tell you I ran a lot of 4-stroke oil through that bike. When I ran out of 2-stroke oil I would use whatever dad had around lol

I did the same with my yz125. I used whatever the old man had in the garage that looked like it was oil. I never cared about ratios and sometimes the bike would be smoking like a chimney, other times burning almost clean.

Other than the exhaust smoking a lot, and smelling like the exhaust of a car with worn out rings and valve guides, it ran perfectly well!

4 stroke oil was originally used to make 2 stroke fuel. I have a old tiller made by a company called Rototiller and the manual say to mix 1/2 quart of 10w-30 to every gallon of gas. The tiller was made in the 40's

He would have kept going but I found out what he did. I was following him and it smelled like popcorn. That was funny. We cleaned it all out and it was fine till he filled it the next time with peanut oil. It was so plugged up with carbon it barely ran. I cleaned it all up again and it ran like new. My friend is now a licensed mechanic working for a Dodge dealership. Now that is funny.

[@Andyshine77]

2 stroke and 4 stroke oils have a few major differences, the largest is the heavy mineral additives. These additives reduce metal to metal contact and friction under load. However these additives "calcium, Zinc and others" do not burn off at the temperatures engines run at. Because of this 4 stroke oil will leave large amounts of ash in the combustion when used as mix oil. Obviously this is not a problem in a 4 cycle engine that doesn't have blow-by. two cycle engine oils have additives like Polyisobutylene which has excellent anti scuff properties. So yes 4 cycle oil will defiantly work, back in the day that's all that was available. Over time leave large amounts of deposits will inevitably be left behind. Excellent video! I always enjoy them.

[@ProjectFarm]

This is great information. Thank you!

[@blackbirdpie217]

They have taken ZDDP (zinc) out, it was really only there for performance non roller cams. No manufacturer makes them today and classuc car owners have to add it back in.

[@Andyshine77]

Dave B They have taken most of the Zinc out. As you said it was mostly for non roller cams, it was also hard on catalytic converters. However they still use heavy minerals such as I believe bromine and calcium, which will cause build up in a 2 cycle mix application.✌

[@mooman86]

About 10 years ago I was in a situation after a massive snow and ice storm here where I had no choice but to use Rotella T5 IIRC as mixing oil in my Stihl MS880 and it cut downed trees all day long for approximately 8 hours straight without a hitch. It did eventually foul up the plug prety good but that 880 still runs strong and hard like a champ. As a general rule I use 2 stroke mixing oil but if need be i wouldn't hesitate to grab any multi-grade 4 stroke engine oil with the Starburst to use as mixing oil.

I don’t remember “2 stroke” oil even being offered in the 50s and 60s. For our 2 stroke outboards, motorcycles, and lawnmowers, we just used any 30 weight engine oil mixed to a ratio of 50:1. Sometimes when we expected to run the machines hard or during very hot weather, we’d mix it a bit richer (30 or 40:1). I think the 2 stroke oil offered today has fuel stabilizers in it.

[@christophervaughan1650]

[@bobbygetsbanned6049]

It's more than that, before bean oil there was no real difference, and now with ester based oil there is a big difference. Obviously engines in the 50's and 60's were nowhere near as reliable as engines are today, and good oil is a part of that. 4 stroke engine oil contains zinc which ashes and becomes abrasive, you should never run 4 stroke oil in any 2 stroke you care about for that reason alone.

[@paulg444]

even today I would never run a 2 cyc engine with less than 20:1 . Remember, the engine manufacturer wants you to buy a new one in 5 years max.

[@Visionery1]

For years I ran my scooters on a mix of conventional 4-stroke engine oil and petrol, using the measuring cup provided by the scooter manufacturer. Never had a problem. Since the 4-stroke oil is thicker it's important to add the oil before the petrol to ensure it mixes.

Never a problem, and I recall using any brand/weight oil.. many times mixing what was left in those old quart cans together to get a "cup" full. I do know that modern 2-strokes (my boat motors) have much less carbon build up though. Love this channel!!!

thank you for making this video. I was on my way fishing after filling up the boat and already putting the 4 stroke oil in the gas. when measuring the oil I noticed the color was wrong and thought it must have been a new type of oil, as my dad had gotten it and he's been running boats for longer than I've been alive, so he knows the difference between 2 and 4 stroke oil. when I was done I looked at the jug to see what this new oil was, well it was 10w30 lol. we had already ran 20gal of this mixture threw the engine and I just put 10 more gallons of it in the boat. I thought the engine was toast. I found your video on this and watched it before I left the gas station.

Bar oil is thicker and sticky to help it stay on the chain, 30w gets flung off at the tip. Your chain will last longer.

Yeah, I was taught as a kid that 30w nondetergent oil was just fine. And, of course I had to use it several times just for the heck of it. We had lots of woods and chainsaws around when I was a kid; as for the bar, sticky oil seemed best, and about a 50w seemed good enough so that the chain oil reservoir didn't empty too fast.

[@USN_Ret-]

Buddy of mine cuts and sells firewood and he only uses used motor oil for bar oil. He comes around ever so often and picks up our used oil.

[@davidmc8110]

Yeah USN (X Navy Deep Sea Diver here, 87-95 disabled) The only problem I had with lower weight oils was the chain oil reservoir would run out of oil well before the gas tank ran dry, which is a little bit of a pain to have to keep checking it, and if you forget, it wears on the bar pretty quick which makes your chain sloppy side to side in the grove.

[@davidwhitacre534]

Back in the old days we used SAE 30 weight oil mixed at 20:1 in the fuel for a two stroke engine...it worked OK - but the oil is nowhere as good as specific two stroke oils that are available today and are run at 50:1 ratios. The oil used in this test is a multi-grade detergent oil - and all those additives are worthless in a 2 stroke engine. I worked in a repair shop back in the 1970's and we had to decarbon the exhaust ports on most 2 stroke engines when the carbon would build up and block the exhaust ports and mufflers. Modern 2 stroke oils are far superior and lubricate better, smoke less, and don't build up carbon. The test in this video was limited to a very short duration in a low performance 2 stroke........it is not representative of what you should expect in long term use.

Thanks

[@WineScrounger]

Reef aquaria are pretty hardcore. If you want to keep the little generator as a standby unit, consider getting a can of long life fuel. It’s got less cycloalkanes and more aliphatic hydrocarbons, so it’s more stable over time. Another solution would be to get a camper battery and an inverter, that will get you a few hours at least, depending on the size of the setup and demand from essential pumps, heaters etc.

[@jasepoag8930]

I've considered battery options, but I've used this generator twice, and it's gotten me through half a day just fine. All I need to run is my water pumps and a heater. The thing is rated at 800watt, so it should be able to handle that no sweat.

when we were teens back in the 1960s we rode BSA 2-stroke motorcycles called BSA Bantams, and other 2-stroke motorcycles made by James (all made in England, using Villiers 2-stroke engines), and there was no such thing as 2-stroke oil back then. In fact on the gas cap of the Bantam's gas tank, was a built-in measuring cylinder on which was engraved by BSA something like " use 3 full measures of this cylinder of oil per tank of petrol, use SAE 30-grade motor oil." I use chainsaws and other 2-stroke engines, with standard car-motor oil instead of 2-stroke oil in the mix. I hope I'm not damaging these engines by doing so.

Vegetable oil is very diverse. 2 stroke bikes in the 60s and 70s used the original "Castrol R", which was a castor oil based lubricant, or "Blendzall", also a castor based oil. They had a distinct exhaust smell. Oil technology has come a long way. Saab used to have a 2 stroke 3 cylinder car. It had a lot of problems. An engineer friend told me that if they had had modern 2 stroke oil in those days, it would have probably been fine. Having driven tens of thousands of miles in my Mercedes diesel car and Ford 7.3 diesel truck with vegetable oil fuel, I can tell you that I would NEVER put it in the crankcase! With 2 strokes, you are lubricating the rings AND the bottom end with the fuel-oil mixture. Not a good idea.

back in the 60s i had a 150cc 2stroke motor scooter. i used to buy premixed 2S gas from the gas station. Every 5000 miles i had to take off the head to decarbonize it and every other decarbonization i had to put in new rings. if i din't decarbonize it, it would overheat and lose power. Today i have a two strike evinrude 65hp boat motor. it requires TCW3 2S oil. That stuff is fantastic. i now use it in all 2S equipment, chainsaw, weedwacker, etc. there is zero buildup of carbon on the head. The walmart brand is very cheap and comes in quarts or 16oz which is perfect for a 6 gallon tank for the boat motor at 50:1 (actually needs 15.2 oz).

Great points regarding modern 2 stroke oil compared to using 4-stroke oil!

[@sandergoldberg4508]

or even old fashion 2 stroke oil. I have a feeling that using regular motor oil, except synthetic, will quickly carbonize the head. I sure you realize the problem with that is not the minute reduction of displacement, but that the carbon layer on the head becomes red hot and that quickly messes up the ignition stroke. In addition, the carbon kills the cylinder wall and rings much quicker and there is a compression loss. With TCW3 it's like a miracle, because the lub quality is as good if not better, and there is virtually zero carbon deposit.

In the 50-60-70ties I grew up in my fathers motorcycle shop. Many times I filled the above ground petrol dispenser with sae 30 oil and gasoline from an underground storage tank. My guess is that on average at least one of our mechanics was busy decarbonizing exhaust ports, cylinder heads and, producing a huge quantity of smoke, the exhaust and mufflers. When later Shell introduced 2 stroke oil this all changed. The chromium plated cylinder walls, that allowed less oil to be mixed with the petrol, did the rest. A huge improvement in keeping the narrow streets in our city free from smoke when all the workers went or came back from work. I now found out from the remarks that my dad didn’t add this sae 30 oil to get more work but simply because 2 stroke oil did not exist yet. Thanks for this you all ! Gerard, the Netherlands

[@chiefredelk8388]

Talking about Chainsaw bar and chain lub. I bought some from a big box store because it was cheap. I know Chainsaws after 40+ years and by the sound I could tell something wasn't right. The trick for checking chain oil showed a nice spray yet didn't sound right. Since I doctor up my bar oil a viscosity check revealed, no slicky, no sticky, and it was just a basic 30 weight oil. One thing I often add is STP, another is a very good oil additive for cars. One drop of my doctored up bar oil on a finger tip then wiped complete dry still leaves a slick finger tip. Bar oil needs to be slicky and sticky yet thin enough to properly flow. Not sure about using but those multiviscosity motor oils but it may thin out some in cold weather and actually be a good idea for that reason since some loggers actually do thin their bar oil in cold weather. I'll do some testing on that and see if filtered used Mobile1, 10w 25 can be doctored up for bar oil. When running a 24 inch bar on a 60cc saw and going to a longer bar, even if the engine pull the load the Chain may starve so often we thin the bar oil to compensate. On one saw of mine I've adjusted the oil pump for full flow and went from 24 to 28 inch bar with great results. However some cheap saws have a fixed oil flow. When oiling Chains there are many factors involved. Many bar oils sold locally aren't really very good and most NEED STP or something like that added. When sawing I don't want to hear that metal on metal sound. Good day.

[@THX..1138]

I've seen several 2 stroke engines destroyed by use of the wrong oil. I have to admit I even wrecked one myself before I understood how important the proper 2 stoke oil is to some engines...Both engines you used were low RPM engines that run at temperatures similar to a 4 stroke which is why it worked. Those engines can use the same 2 stroke oil as boats which isn't too different from 4 stroke oil. Something like leaf blower or string trimmer that turns RPMs north of 7k and runs twice as hot use a 2 stoke oil that has a TC rating. Which is often synthetic and has additives to withstand increased heat & friction without breaking down. Neither 4 stoke oil or even 2 stroke boat oil without a TC rating will last very long in something like a string trimmer. With those engines at best you may get an hour of run time before you've killed the rings and likely the cylinder bore.

I’ve never bought 2 stroke oil in my life I always just mixed 4 stroke in lol

The questions I have always wondered, but was never willing to test... Thanks for answering them!

[@ProjectFarm]

Thank you!

Would be great to see this just with used motor oil! We all have used motor oil from car oil changes, would be great to recycle it by using it in a pre-mix for 2 stroke engines! I expect it to be fairly smokey since their is a lot of carbon in used oil but would be really neat to see!

Thank you for the video idea!

I use used oil in mine . Always have never had any problems.

[@robertspencer5219]

Wonder what happens if you go the other way and put 2 stroke oil in a 4 stroke engine?

[@ProjectFarm]

Thank you. I tested that a while back and the engine survived, but there was a lot of blowby.

I do this and i got a free kohler mower that i fill with Xd-100 oil. i rigged up oil injection that pulls oil to the carb and i run it as a total loss lubed motor. Also you cant go wrong with silkolene pro 2 SX as it is a straight 40W 2 stroke oil. Most 2 stroke oil surpass 10w30 and can take more heat. Dont be afraid to try it. The xd-100 burns clean as it goes through. I cant wait to try Castor 927 maxima in a detroit diesel2 stroke 8v92 oops thats a 2 stroke that burn a lot of oil anyways. I have ran pensoil semisytheic tcw3 in the crankcase of my old 69 deville 472 many times with no problems.

I run xd-100 2 stroke oil in my free kohler mower for years and it’s the best so far, I will never go back

[@jlo13800]

I do it all the time

[@jlo13800]

So far no problem as I feed it into the intake with home made oil injection. I’m on xd-100 2 stroke oil on a Koehler mower I got for free

[@stoggies3546]

Moonshine or pure alcohol for gas would be interesting

[@ProjectFarm]

Thanks for the recommendation.

[@jlo13800]

Loss of power, gas has way more energy per gallon

You are correct with your thinking of four stroke oil. But back in the day, most engine manufacturers recommend to mix non-detergent 30 weight four stroke oil with a good quality gasoline. The biggest issue is more carbon in the chamber. For the most part oil is oil, just make sure you do not make the mix to lean with oil. I personally have been using 2 stroke lawn mowers since I started mowing the grass. My mower of choice is a Lawn-boy brick engine. Made in 1954, and it still runs great. Had to replace the main bushings though. Bet you the new mowers will never run that long for sure. Today they just make cheap junk!!!!!!!! Thanks PF
