Whew what a read. Well no more Rotella T for the bike.

Too....much...reading.... I'm lazy. What's the long and short of this?

Quisp, I have used Rotella T in my bikes for years, sounds like you might have as well, what in the article is steering you away from it? I haven't had the time to fully read it yet (and may not for a while) but wanted to see what you found. Thanks,

I have read the article over and it is very well structured for the data oriented person. THE article concentrate on how much the oil can inhibit wear. For those not wanting to read the whole thing simply search the article for the oil you use/want to know about. The value that he uses is the PSI of the oil breakdown (explained in the article how he tests).

Over 105,000 psi = INCREDIBLE wear protection
90,000 to 105,000 psi = OUTSTANDING wear protection
75,000 to 90,000 psi = GOOD wear protection
60,000 to 75,000 psi = MODEST wear protection
Below 60,000 psi = UNDESIRABLE wear protection

Based on this see where your oil stacks. The highest (first 20 or so oils) are either racing oils or oils with oil wear additive added. He does not recommend using racing oil in street applications as the engine is not in the same heat range or load. He does test a few street oils under track temp ranges to determine where they land.

Again this article is for engine wear only not any other criteria.

Also, you can skip many of the paragraphs. If you see the word naysayers or degreed engineer, go ahead and move down to the next break.

It's not for high performance engines. It's in the 70,000 bracket for wear. He goes on to say diesel engines are overbuilt and carry large quantities of oil . therefore the oil has to fit a price range. Honda hp4 was middle rated as was Valvoline motorcycle specific. I know people with high mileage semi sportbikes using Rotella with no ill effects so I wouldn't sweat it. In his test Quaker synthetic was the shizz.

I posted this on a motorcycle forum. A member knows of this guy from a Chevelle board. Some of the members are on the fence on his test methods and that wear tests aren't the end all of oil quality. He went on to say that this man builds some impressive big block turbo's and normally aspirated.

Saw M1 near the top of the list, proceed to laugh off the rest of the list lol
