Hmm,
RAVENOL RHV 20W-60 Racing Engine Oil 5l Direct Price: £65.99

This stuff is seriously expensive, even before trying to get in here in Denmark....

Think I'll wait and watch.
This is one of the most interesting and scary threads I've seen on the oil question. Manythanks Jim for spending the time on this.
 
Surely it would be useful to factor in the different situations our bikes find themselves in. Right now, in the NE USA there is a prolonged heat wave. Temps we would rarely if ever would see here in the SW UK. So my 850 here would never be stressed like it was in years passed. How much prolonged high speed in the NE USA v. SW UK? In Jim's area speeds are higher for longer probably. Is his bike stock compared to ours? So
many factors to consider and I suspect they have a fair amount to do with what oil you can safely run.

Very much agreed.

I would hope that when Jim has finished, he will summarise the 2-3 mid range oils best suited to 95% of normal road users, the 2-3 oils best suited to high stresses race type motors, etc.

Like I said, I hope that’s what yer gonna do Jim??
 
The problem with the anecdotal oil testimony ( such as: I use any oil from any source, whichever is cheapest and I've never had an engine failure) is they do not know how close they are to an engine failure. Many times I've heard people say, "She was running just great before she blew up". This running versus blowing up is, for the most part binary. It is either go or no go. No accounting for degradation, adverse conditions, etc.
 
Finding a number of good candidates now.
Rotella T6 synthetic test still planned?

I looked for my supply. My bottle is empty and it's only available in 1 gallon containers at the store.
So if I can come up with a little I will test it.

And I came up with some. I will get it tested. Jim

“Suitable for cabinet door hinges” !! :eek:

If you don't mind squeaking, prematurely worn out cabinet door hinges:)

Safeway Scotch brand would have been fun to test . I don't think it exists anymore.
My Cousin' Ford pickup with camper did a soft seize with a sumpfull of the stuff. Hot day on a hill, the oil was so thin it wouldn't cling to the dipstick, just ran off like water.
Cheap tho, on sale at 69cents a quart back in the 80s!

He changed the oil to some RPM Delo 400 on the spot and the engine survived.

Here is the scar from the failure of the MPT 20W60
Only one little seizure mark -and yet with almost 300 lbs on the follower it stopped the 1 horse arbor motor instantly.

Jim Said,
"Now the new looser
Aeroshell W15W50 conventional aircraft oil
Shortest test ever
Failure was immediate when I lowered the load arm. I thought something must have been wrong so I repeated the test, same result.
Suitable for cabinet door hinges."

Aero Shell is not made for flat tappet engines. I have heard Aviation mechanics say, "It has an ash-less dispersant and does not support flat tappets." The engines it is used in have roller cam followers. One of the worlds quickest ways to destroy a motorcycle engine.

I am very disappointed in the performance of the Amsoil 15w50 racing oil! It is coming out of my bike before I run it again!
Thanks Jim,
Dan.
 
From my reading, there are a lot of small aircraft running flat tappets.
I'll bet there are a few that have both flat tappets and Aeroshell Conventional Aircraft oil in place.
Look out below!

I had heard that too, now I know that...

There are a lot of older aircraft engines that still use flat tappets. Of course they run low rpm and low valve spring pressures. They do report a lot of cam problems also.
