Thread: Diesel Oil in Bike Engine?

It's part of the detergent additives.

In other news. . . Kragen had a 2 for 1 deal on Mobil Delvac 15-40 today. So, looks like that's what I'll be using for the next couple oil changes.

[quote=Anorak]I had an issue of Hot Rod from about 1968. In an article about Dick Landy's Super Stock cars, he said he used gear oil on the front wheel bearings instead of grease. For the 1/4 mile, it works and he was more than competitive. Big trucks have had bearing oilers on all axel bearings for 40 + years . Along about the 80's good oil seals started showing up so 200,000 miles on bearings is normal And thats at around 15,000...

Yep, Rotella Synth from Walmart for anything with a spark plug in my house. I run a Rekluse in my YZ450 by the way. Dirty

Wet clutch.

Without long term analysis, perhaps starting with a baseline that documents all the tolerance of the engine prior to putting it in service and then and the end of a long, like 100,000 mile duration test and then remeasure all the tolerances how can you...

Ya back when oil was still oil. And that BMW stuff still has what it should. Diesel oils are changing though, they've been reducing ZDDP in diesel engines as well to meet EPA emissions requirements, I think they are refered to as CJ-4. What this means to you, could vary, but watch it in the future, to make engines cleaner they are fitting more catalytic converters, which get plugged by having ZDDP in the oil. And so these oils might be...

Acejones--it may not matter to u at the moment,but, to the 2,3 and 4th owners of that same machine it will!.
