Can Engine Oil Be Proven To Last 20,000 Miles?

[@EngineeringExplained]

Hope everyone is having a wonderful holiday season!! There's a lot of information packed into this video, quite a bit of preparation and fact-checking went into this, and I know it's a massive amount to consume. I learned an immense amount over the two days I spent at their facility learning about the testing, and I believe this video captures what I saw very well for only being a 20-minute video. It was fascinating learning about how much testing goes on that we rarely hear about, and it was super cool to see the viscosity and wear metals analysis with time over the 20k mile drain intervals (as demonstrated towards the end of the video). It's a long video, but I'm quite proud of how it turned out, and I appreciate those of you who'll take the time to watch from start to finish - really tells the whole story! Thank you all and Happy New Year, let's have an amazing 2018!! instagram.com/engineeringexplained/

Well i dont know if it does what it claims but i use this oil in my small engines since they ever get changed more then once a year. Seems to run clean and even start well in colder weather.

[@vhjioa]

Would you rather change every 10,000 miles with a cheaper brand or every 20,000 miles with a Castrol or Mobil 1?

[@kevintibbetts5249]

I run Amsoil full synthetic diesel 15-40 in my 03 duramax lb7 and change the oil every 25,000 - 30,000 miles. It's winter now here in Maine and just above 0 degrees F. My engine has 280k and still running strong. Ill be pulling it out for head gaskets and injectors at 500k and am very curious to see how my bearings look. Your videos have helped me with mechanical understanding more then any other source of information. Thankyou and have a great new year!

[@ralphwood8818]

Im not an oil change enthusiast. Im a bypass depth filter enthusiast. Before synthetic oil I changed the bypass filter every 2.000 miles and added a quart of Delo. With synthetic oil I do it every 6.000. That works for me. With Mobil 1 with 250.000 miles with no oil drains and a depth bypass filter change every 12.000 miles I mentioned it on KZbin. A Caterpillar lab manager sent me a sample kit. He said the oil looks good for that many miles but suggested a 6.000 miles Frantz filter change every 6.000 miles instead of every 12.000. The Subaru didnt need oil added between filter changes. Both head gaskets started leaking oil at somewhere over 250.000 miles. Yes Mobil 1 will last 20.000 miles. Better if you keep it clean. Im using Walmart synthetic and a Australian Jackmaster Classic bypass filter in the Pontiac Torrent.

Lots of incredible information here. With that, I change my oil and filter every 5000 miles, I use full synthetic. Changing your oil is the cheapest and easiest maintenance task to perform on your vehicle second only to changing your air filter. For me, testing the limits of the oil science is simply not worth the price you may pay for premature engine wear due to dirty or broken down oil. Thank you again for your extensive and very well put together video.

[@Stoff1]

Do you change any other service items 4 times earlier than recommended?

[@jibrilthegreat35]

@@Stoff1 recommended? No manufacturer recommends 20k mile oil changes. As a matter of fact, they say to change oil sooner if you drive in severe conditions which includes everyting except cruising down the highway in 75 degree weather. Im a seasoned mechanic, I recommend 5k mile oil changes.

[@maksymfedoriaka2851]

@@jibrilthegreat35 some do. My 2019 Ford Focus has a recommended oil change interval of 30000 km (18000 miles) or 2 years, whichever comes first. Think about it, why develop the oil that is marketed as lasting 20k if there is no car manufacturer that recommends that schedule. Not sure if it's good advice from Ford, but I'm sure most owners follow that schedule, especially when vehicle is under manufacturer's warranty. What bothers me is that this interval is twice as long as the one they recommend for 2012-2017 models with exactly the same engine as the new car

[@nordvestgaming1238]

@@maksymfedoriaka2851 The other part that gets me skeptical is that it is in the company's best interest to make sure the car makes it through the warranty period, but they also want things to fail on the car afterward. I am not necessarily saying that want the engine to blow up immediately after the warranty period is up but they do likely want things to break because then people have to buy parts, and many people will take the car to a dealership to have it repaired and so they continue to make money from the vehicle even if it is already paid off. To me, it seems like part of the reason why there are a lot of old cars are still chugging along with little to no engine issues, which run thicker oils with more frequent oil change frequency vs a lot of modern cars that run very thin oil and don't change it nearly as often. Especially since a lot of people are only keeping their cars for a few years, it all kind of begs the question for me if they are making these maintenance recommendations because it is the absolute best for the longevity of the car or if it actually isn't the best but they can get away with it since they know most people will either just buy a brand new car or continue to fix their current one.

[@bullrage74]

​@@nordvestgaming1238I've also heard this theory from other mechanics who believe manufacturers suggest these long maintenance intervals to make it seem like the maintenance cost is low for the first owner. It makes it more likely that that customer will then buy another car from that manufacturer in a few years and rake in repair bills when the next owners have premature failures due to the long maintenance intervals. "Lifetime" transmission fluid is also bogus.

[@thaladriataeyeon3265]

The whole "my dad doesn't trust this and he's been a mechanic for 30 years " line.

[@Candisa]

It's normal to be sceptic about it, especially when the risks are sludge blocking ever so small oil paths, lack of proper lubrication and cooling of downsized engines with small sumps... My car has a maintenance interval of 30k km (18k mi), I've changed it every 10k km (6k mi) since new, which will happen for the 5th time soon. I do plan on ordering an analysis on the oil at 60k km to see if I can switch to 15k km (9k mi) intervals, but I simply won't risk doubling that in an engine that only holds 3litres of oil and gets driven hard with a mild ecu-tune on LPG fuel.

[@1barnet1]

Candisa My car has 30k intervals too but limited to 1 year. (Because oil filter gaskets mostly) If they have to change the filter I just tell them to change oil too. Better safe then sorry especially when your paying for the labour anyway. That being said apart from checking fluid levels i trust it to last the miles/Kms I drive for the whole year. Which is 20-25k km or 15+k miles. And it has without an hitch for 3 years (0.9 L TcE with 105 Bhp)

Technically speaking, if you never replace the oil, it can last the entire life of the engine. It'll just be a much shorter lifetime.

[@warrenpuckett4203]

My sister did that

[@barrykery1175]

A friend of mine had a 1972 Plymouth Duster. He put over 100K miles on it and NEVER changed oil. At that time I figured he was crazy. I would never do that, but it was done. Now....was the engine pretty much spent after that? We have no idea, the car was sold.

[@ralphwood5114]

Back in the 60s we serviced telephone company trucks. We didn't change the oil just the filter. They knew the engine would be a mess when they traded it off. They knew if the engine was clean it wouldn't be worth any more. Bean counters at work.

[@ralphwood5114]

A good motor oil will last as long as you keep it Clean and don't over heat it. Took me 20 years to put 250 K miles on my 84 Subaru 1800 with no oil drains using a toilet paper filter and Mobil 1 15-50 racing oil. The Nissan Altima probably couldn't handle 15-50.

[@darring.9161]

[@darring.9161]

@. Perhaps so, and you probably can go 2 Years...but I still wouldn't do that to my Engine. I think 1/Year Oil Change is plenty enough considering that you may change your Conventional Oil up to 3 or 4 Times/Year. Just because you can do it, doesn't mean you should or it's a good idea? Fact is that even Synthetic Oils will still accumulate a lot of soot and metal particles over the course of a year, and you just can't go by the colour of it on your Dipstick either. This is only my opinion of course, and what you do with your Car is your business...but if the Oil is appearing Black on your Dipstick it probably should've been changed a long time ago! Synthetic does a great job of controlling the sludge and varnishing but the Oil is still going to be quite dirty and contaminated in about a years time. Of course, this is also dependant on how much you drive and whether or not it is City or Highway Miles. But if your happy doing it that way...??? I get all of my Synthetic Oils on sale for nearly half off and the Mobil-1 or PurolatorBOSS Filters too, so the little extra cost is negligible and well worth it...all my Engines run like a Swiss Watch and I intend to keep them that way!

[@frederickburns1739]

Very informative but the average person cannot comprehend all that you presented. I am a retired Cat, Cummins, Cleveland and etc. mechanic and understand all to well what you presented. Back in 1972 I started using Mobile Delvac 15/40 in all my own personal engines; a diesel oil in gas engines. I had a Briggs & Stratton 3 & 1/2 hp mower that lasted 24 years on that oil and a 2.5 GM 4 cyl. that survived 300,000 miles on Delvac 15/40. Today I use Shell Rotella 5/40 synthetic in both my vehicles which both have over 130,000 mile and do not use oil between oil changes. And my oil changes are between 10,000 to 12,000 miles with oil filter change at mid stream. Oh yes I predominantly use Baldwin oil filters.

[@_BAD_MERC_]

This was extremely well made and definitely easy to understand for the not-no-mechanically inclined. I have been around cars my entire life and watched my dad put 20w50 in everything. Once I got older I used what the manufacturer specifies and believe the archaic 3,000 mile change interval is WAYYYY too soon. That was for old cars with blowby and poor efficiency. Engine tolerances today are not measured with feeler gauges, they're measured in microns. My daily driver gets a Motorcraft filter and 5w20 about every 7500 miles and with 137,000 miles the oil is still clean when I change it.

[@jameskoralewski3583]

What measuring device can you use to measure microns? Why do you say older cars had blowby problems. I've owned cars all the way back to the sixties and never had any blowby problems. Blowby is usually caused by high compression or by bad piston rings. I've owned high compression muscle cars but non of them ever had or developed blowby problems. Diesels have a lot of blowby, partly due to their high compression engines. and partly due to the kerosene they burn.

[@micheals1992]

is it bad that I see smoke when I remove my oil cap after a journey? I presume that's caused by blowby. I have a 1L naturally aspirated petrol aygo with a compression ratio of 11.5-1. the car is designed for fuel economy. the oil tends to stay pretty clean though, I use premium castrol edge 0w30 oil

[@MrScary67]

For what it's worth, I have used the Mobil One 15,000 mile Full Synthetic since I got my 2008 Focus with 26,000 miles on it (bought in 2012). I also use their high mile oil filter. I routinely change my oil between 15,000 and 16,000 miles. I actually just changed it last night after 16,800 miles. The vehicle now has 326,000+ miles on it. It still runs strong! I'd say that's a good testament to many things about the car but also to their product. I don't think it's a huge stretch to say the 20K oil would work. The only reason I do not use it is the 15K oil is half the cost. So at that interval, I don't mind changing the oil at 15,000-ish to save a few bucks.

I've gone 2 different times on 2 different cars, 22,000 on one and 24,000 on the other before changing the oil. Both cars used Castrol GTX. One due to forgetful negligence, the other due to being broke and not having the time and place to do it. Though the oil came out almost jet black both times, I checked under the valve covers and everything still looked shiny with no sludge. Though you COULD go that long on a good oil, I really don't recommend it despite what manufactures try to make you believe.

[@shrujanamsyama9940]

Sludge is not in the oil that drains but in the fuel sump and the corners of the engine parts. Also, there will always be wear metals that will damage the engines. There are cars that have been abused and no oil changed for longer but they will have a toll on engine life. So, as long as you don't care about engine life, do what you want

[@donnysanner342]

I'll stick to my Pennzoil full synthetic and change it every 5k. It's cheap , it gives me a chance to visually inspect everything under my car and most of all it's cheap insurance.

Why, for $35 you can send oil to Blackstone Labs and get a full analysis.

[@Regulated-Liability-Network]

Regular oil changes at 3-5k intervals can extend engine life and reduce wear. Videos on KZbin show the difference between engines with 10k and 3k oil changes, with the former having significant varnish and soot buildup. Engine oil cools the engine, but soot buildup decreases its effectiveness, causing increased friction and heat. This might lead to oil burning. But yes the oil can last & also the damage that’s caused by changing at 10k. I do 3k on my vehicle.

Interesting. With Hondas they say don't change the oil until 5,000? A video someone had an oil expert and he said the first 100 miles of an engine causes the most wear and metal filings. So he said at 100 miles REPLACE the factory break in oil with fresh break in oil then change it again at 1,000 with regular oil. What do you think?

Synthetics are the way to go with most gasoline and diesel engines. In the mid 1980s through the late 1990s we ran Amsoil in our company vans (Dodge 318). We would change the oil every 20,000 miles with an oil filter change every 10,000 miles. We were putting 80,000 to 100,000 miles a year on each van and trading them off around 400,000 miles. We NEVER had an oil related problem with any engine we just preformed normal maintenance and replaced the timing chain every 150,000 miles (we found that the timing chains would stretch and jump a tooth around 160,000 miles, it was cheaper to just replace it before it happened as opposed to the downtime out on the road) Once our supply of Amsoil ran out we switched to Mobil 1 with the same results. In 1998 we started switching over to Dodge Trucks with the 5.9 Cummins Diesel we ran Mobil Delvac 1 which is a Synthetic Oil for Diesel Engines. We changed oil every 25,000 miles with a filter change around 12,500 miles. My company truck 1998 3500 was traded off at 289,000 miles after fifth gear went out for the fifth time (design flaw with the NV4500 transmission when used at higher gross weights, Truck was routinely hauling 20,000 lbs or more)

[@nunyabiznis817]

It would be interesting to know why, after all those years of using Amsoil with no problems, you decided to switch to another brand.

[@TheBlazen001]

[@dyg3sta]

30-20 years ago engines were build with cast iron, oil canals were not that small, lot of parts were designed to last long. Now there are many types of metal used for engine build, they heat up differently which means expand different and in different time. Oil canals are often smaller in diameter which requires better and more often changed oil. When you do long distances engine wears sgnificantly less. You can do with same car 400 k miles in 10 years and have better condition engine than 100k but short distances like 5 miles each

[@flybyairplane3528]

Nunya Biznis he said ONCE HIS SUPPLY RAN OUT, then he used MOBIL1

[@Sc-tch]

@Nunya Biznis, I'm guessing Amsoil didn't have a diesel oil at the time.

[@thromboid]

Pat Goss suggests basing the oil change schedule on engine run-time rather than distance travelled, so it's interesting to see Mobil using viscosity vs run-time as one of their measures. What's your opinion on the idea? It makes sense that distance alone isn't an ideal measure, as it doesn't account for time spent idling, and it's notable that the "severe" and "normal" schedules often correspond to similar run-times (e.g. severe: 6000 km / (40 km/hour) = 150 hours, normal: 12000 km / (80 km/hour) = 150 hours).

Billie Bob Norton III That is a legal issue not a technical one.

[@useryggfdcc]

Legal only, technical not.

[@jameskoralewski3583]

The only time your warranty will get voided is if your engine breaks and they ask you to prove that you changed your oil according to their interval. If you had it done there, no problem. Just don't get caught without confirmed proof that you changed it according to their schedule. If you changed it yourself, you have to retain all your receipts for purchasing the oil. If it was changed by a third party shop, keep all their receipts showing the oil purchased and their work to change it. Until you apply for engine repair warranty work, however, they have no knowledge if you followed the warranty verbatim or not.

[@thatcrazywolf]

Or just buy a KIA they warranty everything

[@darrylsjodin7184]

If the engine fails, it has to be proven that it was the oil’s fault with extended drain intervals that it failed for the mfg to void the warranty. Amsoil will cover your engine if it failed due to Amsoil failing when used as directed.

Glad you mentioned at the end about still needing to check your oil level during that year. Most people dont realize that especially modern day engines have an acceptable amount of oil burning duration that an oil pan cant make up for in 20,000 miles. For example, most Chrysler engines consider an engine with over 50,000 miles, can burn up to a quart of oil in 900 miles. This is their acceptable amount. So your average 5qt to 6qt engine will run itself dry in 6 months, not counting the damage occurring due to running low on oil to even get to that point.

[@mooglemy3813]

Trucking companies have engine oil samples taken and analyzed frequently. High mileage engines that show abnormal characteristics such trace main and rod bearing material, trace coolant and other contaminants of wear etc in the engine oil get rebuilt depending on the tractors age and so on. So a refresh rebuild maybe gives a rig in good shape another 1 M plus miles or they can flog the rig before even a planned less costly repair. If I was going to do 20 K miles on engine oil I'd want to do oil sampling. And maybe swap out the oil filter at 10 k miles. If I had a good beater that I was driving and the engine is A OK and I checked it over, maybe I'd try that. Hey 5 oil changes in 100 K miles not bad. But not doing that with my good ride. OEMs recommended oil change is quite high now, mainly because its sells a vehicle with less maintenance required, like iridium spark plugs. But for my money and experience I change the hell outa the O&F and do a complete ATF change out way before a recommended or partial one. Treat it right and ittl reward you with reliability. Otherwise???

I pulled about a pound of sludge out of the valve covers and off the top of the cylinder heads and rocker arms. Oil change sticker indicated the oil in in at that time had about 14,500 miles on it. Plain old Pennzoil conventional. Drove it for 23K miles and replaced the intake manifold gasket and pulled maybe two pounds of sludge out of the lifter valley. The distributor was about frozen, could barely turn it by hand so I replaced the distributor. I'm still driving it and would estimate that in the first 20 years it had maybe one or two oil changes. Some farmers top off their engines with what they have on the farm, good old 15W40 diesel motor oil. Likely how it has survived before my TLC took over in 2011.

Not True. The interval listed in your manual is only demanded and required during the warranty period. After that, it is only listed as a recommendation and you are not required to go by that interval listed any longer. If you're out of warranty and don't go by his numbers, what is he going to do to you, take away your birthday? Once your car is out of warranty, you can change it as often as you think is necessary to keep the engine protected. Of course, the dealer wants you to go by this frequent interval so he can sell you his oil more frequently and charge you as much as he wants to charge. If the warranty is over and you don't go by the owner's manual, what is the dealer going to do to you, take away your birthday?

You mentioned oil consumption at the end, but you did NOT mention what happens during the MADS testing if/when an engine requires more oil during that 20k mile interval. Assuming they did not run the engine on low oil volume, some quantity of makeup oil has to be added, which as luck would have it, fixes a lot of ailments an oil running for 20k miles might start to develop. I used to run Mobil1 in all of my vehicles until a reformulation caused it to increase oil consumption to 2-3x the rate it had prior. This wasn't just in one engine, this was across several platforms: 6L powerstroke, 4.6L V8, 3.9L V8, 5.4l V8... not mine, but related, 4L explorer and whatever V6 was in an Escape. Engine mileages varied from 20 to 80k miles... and the consumption increase was a function of time, all right around spring early summer. We all were scratching our heads. A change of oil brand eliminated the additional consumption back to normal previous levels. With the purchase of 14 E63 AMG s model, it required 0w40 oil, initially M1 was the only offering and it too succumbed to the same problem of high consumption. Switched to Castrol GTX, and it dropped significantly. Still higher than any other motor I maintain, but that 5.5L twin turbo puts out more as well on the thinnest oil of any motor I maintain. I no longer use Mobil1 in any application. I refuse to pay top dollar for a product that evaporates.

Idc what the bottle says, on my 2021 Dodge Ram it says in severe weather where the truck will be doing lots of idling (I let it warm up for 20 minutes every day in the winter where it is regularly-20C) it is recommended that the oil is changed every 6500km or 350 engine hours.

James Koralewski did you read my comment? i said Mobil 1 full synthetic. not Standard Mobil 1...

[@jameskoralewski3583]

All oils, branded Mobil 1, have always been a full synthetic oil. I didn't say standard Mobil oil, that would have referred to a non synthetic oil. I said standard Mobil 1, which refers to the first formula of Mobil 1 when the synthetic oil line of Mobil oils was invented in the seventies. There sell several formulas of Mobil 1 for sale at this time and the Mobil 1, mentioned in the video, is their latest formula and is called Mobil 1 Annual Protection.

My 1986 Chevrolet C10 with the 350 V8 (5.7L) came with a factory oil change interval of 7,500 miles and a filter change interval of 15,000 miles.

[@normt5463]

Get a Honda and Subaru and the level drops with consumption you would be adding new and eventually only have to do a filter swap!

[@procrastinator1842]

As a Subaru owner I can confirm that oil does not stay in it long enough for a factory service interval.

I once bought a new 2004 Honda Accord. It was the worst vehicle I ever owned. I'll never own another Honda vehicle. Toyotas one the other hand, have been great vehicles for me. My 1998 Jeep Grand Cherokee has been a great vehicle as well. I bought it new and it still runs like new today.

I used the 12,000 mile mobile oil last November 2019, have had no problem...Next month 12,000 miles is up...Going for the 20,000 mobile oil with the 20,000 filter...Best product mobil has made for no hassle oil changes once a year.👍👍👍

[@captnjim44smith74]

I started using Mobil One in 1977 after it hit the retail market. Since it’s very expensive, I started my 24,000 mile oil change. I checked the oil cleanliness from the dipstick. If the oil gets darker, I changed the filter. I still use Mobil One after about fifty five years.

[@MichaelCzajka]

Using a magnetic sump plug is a simple way of checking if your oil is lubricating properly i.e. A lot of metal on the plug is bad and a small amount is good. A drop test of the oil can also give you some indication of how well it is lubricating 🙂

[@darrylsjodin7184]

There really shouldn’t be any metal on the magnet if your engine is sound.

[@MichaelCzajka]

There is always metal in the oil eg. ~17.52 min where they graph the wear in ppm Thus there is always some iron (Fe) on a magnetic sump plug. The best you can hope for is that the amount of iron on the sump plug is minimal. If there was no metal on the sump plug the engine would not be wearing... and that obviously doesn't happen. Please take a look at a car oil analysis if you're in any doubt that there is ferrous metal in the oil. 🙂 P.S. Perhaps you're thinking of a non-magnetic sump plug? i.e. Most cars don't have magnetic sump plugs.

[@darrylsjodin7184]

@@MichaelCzajka Yes, I’ve always known there is wear metals in the oil, but I wouldn’t want to be able to see or feel it.

[@MichaelCzajka]

If an oil analysis shows iron then you'll also see it on a magnetic sump plug at oil change time. The magnet picks up about 50% of the circulating ferrous metal. The oil filter would remove any bigger chunks of metal over ~40 micron and the magnet would pick up any metal smaller than whatever is being filtered. When the oil changes colour and becomes darker part of the colour change is due to the wear metals in the oil. If you rub the stuff on the magnet between your fingers you should be able to feel the metal particles. Have you seen what the build-up of metal on a magnetic sump plug looks like? I can post links to examples of sump plugs with low and high wear if you like? 🙂

[@darrylsjodin7184]

@@MichaelCzajka yes that would be cool to post the pics. I think I have seen it before; it’s so fine that it turns your fingers black? Also, I would like to know how to post a picture. Never been able to figure that one out. 😆

[@jamescaley9942]

The most important practical data point consumers might want to know is if the measured power is degrading across the lifetime. Did the engine lose 5%, 10%, or 30% of it's original power? How did it perform during running in? All results would need to be compared with competitor oils (or maybe semi-synthetics). If you've gone to the trouble huge expense of putting a car on a dyno for that long, I am surprised that kind of critical data was missing. And of course you could do compression testing. Also missing was to consider if the interval should be mileage based or time based or combination of both. Also I missed how many cold starts were included in the dyno testing. Isn't that were most engine wear occurs? That is a key selling point of mobil 1 - 0W rating for better cold flow.

[@EatPezzzz]

I change the oil in my work van once a year, every year, whether it needs it or not! 400k miles and counting.

@@paulna5526 It's a testament to synth oils longevity, used mainly for motorway driving. E.g. Averaging 20k a year over 20 years = 400K

Is your mpg same for first 10k and 2nd 10k? Even with 1 mpg decrease it will be worth to change in 10k .

[@faust82]

Since the oil is rated for 20000 miles or one year, whichever comes first, that's a solid approach. My car has a staggered service interval, but I get an oil/filter service done every summer before the vacation season (that's when I put the most miles on the car). BMW says 30k km between oil changes, but I barely do 8k a year (very short commute).

[@tonybailey89]

Thanks for the impressive articulation of a BUNCH of complex information as always, driving a 2013 Sonata with full synthetic..Hyundai says change every 7500 miles...I've got a lot more confidence to at least go 10,000 miles between changes with this information and solid testing!

[@-DC-]

Extended oil drain is normal in Europe these days the days of 3000 mile oil changes is long over unless you own a lube shop.

[@Acroposthion]

Well.... Using a crap conventional, with a crap filter - 3k intervals leave a safe margin. Even then, some engines would still sludge-up over time. Prolly most watching this vid are more inclined to take better than the crappiest care of their equipment though, I’d surmise. Just be especially wary of the $10 oil change special, down at your local “Goofy Lube” haha!

As a Honda Factory Certified motorcycle technician, I must say that Mobile 1 does a fantastic job of eliminating friction inside an engine. My first experience with this was way back in 1995 when a customer who had just bought a brand new GL1500 Goldwing wanted to do his own initial (600 mile) oil/filter change, I saw him at the parts counter getting a filter and I presumed oil, he only got a filter, I realized this when I saw the bike on a trailer 3 days later when it was brought into my dealership, guy is fuming mad!! Says the bike is junk! (Honda??) The bike literally would not move, with it idling you could pull the clutch, drop it in gear, let out on the clutch and the RPM wouldn't even change. We pushed the bike in the shop and onto a lift, I am going to pull the saddlebags to gain access to the driveshaft which I'm thinking must have snapped or something highly unusual (but hey, it can happen). When I opened the saddlebag lid to get to the bolts I noticed a partial bottle of Mobile 1, I asked him if he had used this for the oil change, he replied yes. Early Mobile 1 was meant for automotive engines and contains friction modifiers aka teflon or PTTFE. It did eliminate the friction! however, the internal wet clutch needs friction to operate. Ooops. So after a complete engine teardown and cleaning, installation of new friction discs, he was back up and running. Honda paid the labor (though they didn't have to) and the customer paid for the parts. Mobile 1 does now make powersport oil WITHOUT friction modifiers so it is wet clutch safe. Be sure to use the right oil guys! But even that long ago Mobile 1 was as advertised for sure.
