I guess she found out who the dipstick was as opposed to what a dipstick is...

I remember an old girl friend saying, and i quote, "I don't check oil, men check oil"!

I then said, and when you don't check the oil, men will then take all the money out of your purse/bank account, to repair your blown up engine!

She started checking her oil, after i showed her how to do it.

It's not just women, I knew a guy who was asking everyone at a ski club meeting about how often they check their oil. I had a 88 Mustang 5.0 GT at the time and told him I check every other gas fill. Then I asked him, he never checked the oil in his Toyota Cressida and the engine blew. He had about 30,000 miles on it when the engine blew. His comment was that it was a Toyota and they don't need service. DUH!!

Another vote for Mobil 1 here. I ran a lap and a half at Elkhart Lake(4 mile track) with a broken oil pump drive belt in a dry sump system(no splash lubrication) to finish the race at the June Sprints. To my surprise, I finished without losing my position.

Afterward, when I tore the engine down, there was no sign of overheating or excessive wear on any of the crank or cam bearings or journals. I was(& still am) astounded.

My sons dumbass mechanic sent him out for a 12 minute moto with zero oil in the crankcase. This was an 85cc 2 stroke with the majority of the run time literally at WFO. Nary an issue for MANY more motos afterwards.

The oil in the bike was changed often so we did not run expensive oils. I don't recall the specific brand but I would say it was just the most affordable dino automotive oil available at Walmart at the time of purchase.

The standards for oils are pretty darn good.

I am old, so I have owned many 2-strokes. I never ran oil in the crankcase. I never had one fail on me.

The oil gets mixed into the gas and lubricates the lower end as it passes through the crankase as vapor. Lots of small 2-stroke motors still work that way... weed wackers & chainsaws come to mind.

I raced 'em for years and pretty sure that they need oil. The premix is for the topend but not the gearbox. Jus sayin'.

What glory said.

There’s still oil in the transmission and for the clutch. It has a service life like anything else. Especially on a two stroke motorcycle, where feathering the clutch is mandatory.

They need oil in the transmission.
On the 2 stroke Suzuki's I used to ride, the crank bearing on the clutch side was lubricated by the gear oil and the one on the flywheel side had an oil injection line going straight to it, but everything else in the engine was lubed by the oil in the gas.
This is an exception to the rule because the great majority of 2 strokes get no lubrication except through the premix. Those old oil injection bikes were a bit different. They could be run on premix after opening up the case around the flywheel side crank bearing, if you tried it without doing that, the bearing wouldn't get enough oil.

Motor top and bottom end are lubricated via the premix, transmission and clutch are lubricated with the gear oil.

With the idea of advancing the original question, I mentioned my experience with Mobil 1 at RA, specifically because of the type of stresses placed on the engine from running WOT for long periods of time in a 4 cycle high performance engine, running without proper lubrication. The heat and stresses imposed on the oil by the gearbox in a 2 cycle 85cc engine in a motoX event aren't the same, nor is the viscosity(80w90?), so I don't think it's a fair comparison or reasonable conclusion to say that any oil would provide similar protection under the circumstance I mentioned, just because oil technology has improved generally over the last several decades.

It may well be that any synthetic you buy at Walmart, regardless of brand would perform equally well - as Glory points out. They're likely all refined by one of a few principal refineries, but I have no direct experience to represent that assumption to the OP as he requested.

At the time, I considered the cost of running Mobil 1 to be cheap insurance. I had heard numerous stories similar to the one I posted, from others. Since most of the guys I raced with were also running it, I decided to follow suit and switch brands. I had always used Kendall oil previously.

When I was racing 2 cycle engines, most everyone ran Castor "R" as their beverage of choice. While I'd never run it in my bikes crankcase, I'd like to - the stuff smells great! My point being that different applications have different demands that favor different brands.

With ridiculously short engine life, high parts, labor & machining costs, and with the prospect of outright failure being unacceptable, I believe racing communities are pretty good at ferreting out best of breed as long as an oil company isn't a sponsor.

To the OP's second revised question about excessive oil consumption when running Mobil 1 synthetic: I've experienced the same issues as yourself when running it - ie. My oil consumption goes up and my gearbox shifts smoother. I've gone back to running dino oil in my Gen1. I'm sure the protection isn't as good as Mobil 1 and I don't like the noticeable decrease in performance, but I hate adding oil all the time and the stuff is pricey. My bike will almost certainly outlive me no matter what I run and since I'm not racing, I've joined the ranks of ride more, worry less.

PS: My guess is that the synthetic is getting past the valve guide seals which would account for the excessive oil consumption. For all I know, the stuff might be sticking to the cylinder walls so well that its getting burned off with every ignition event. If I cared more, I'd try running a heavier weight synthetic to see if the problem persisted. Good luck with your bike!

Well, The only real difference I have personally noticed between synthetic and good dino oil was... When I opened the motor up, the synthetic oil left less crud to clean out. I didn't see any difference in wear. This was when I was riding bikes that didn't use the engine oil in the tranny and I quit riding bikes that needed to have ring & valve jobs every 40,000 miles back before the turn of the century.

I haven't actually opened up a motor that wasn't electric, in about 20 years now. If I have to take an engine apart now, it's just to turn it into smaller chunks that can be tossed into the trash.

Rather than start a new oil thread I’ll just post this here. My son just called me from Walmart and said they had a new Rotella T6 synthetic that is 15W-40 instead of 5W-40, and it also says “Lower Oil Consumption” on the label. Same price in gallon jugs. Couldn’t find it on Shell’s website. Only place it came up in a search was in a discussion on BITOG.com. Has anyone else seen it? I made him send me a picture.

Was the same as 5W-40 T6. $22-something for a gallon I think.

I'm not going to use it. Just putting this out there for all the Rotella fans.

I only use motorcycle SPECIFIC oil so mine won't esplode.

Plus I thought it was interesting that it wasn't mentioned on Shell's website.
