Re: Engine oil

IMO, 15W-50 MOBILE 1 is da chit! I run it in everything I own.

1985 Fleetwood (engine and diff.)
1999 V-Max (engine, trans and final drive)
1997 HondaST 1100 (engine, trans and final drive)
1999 BMW R1100RT (engine and final drive)
2000 Honda CR500 (trans. w/ wet clutch)
1991 Syclone (engine, trans and diff)
1978 Honda Z50 (pit bike)
1986 Suburban (engine and diff)
1972 PDC Ciggarette Boat
1986 Mastecraft Ski Boat (engine and Velvetdrive)
1971 Snapper Lawn Mower
the list goes on...

I'm not saying everything else is crap. I'm just saying. I've NEVER had a prob w/ it even in turbo's.

Re: Engine oil

Yup, Mobile 1. Somewhere here there's a pic of an motor that was torn down running Mobile 1 and that thing looks like it was put together yesterday. Impressed me. However I used to have an airplane and I used Shell semi-synthetic 20w-50 and NEVER had any probs in 2500 hours which is like 375000 miles or more. Also years ago I had some big trucks and ran Shell in those and never had any oil related prob there either. Just use Mobile 1 cuz that's what GM says and everything I've seen here is Mobile 1. Synth big advantage is at the temp extremes among other things if you look at the tests. IMHO any high end-oil changed regularly would prolly give good results but why be a beta tester. Only difference would be on initial startup on a new motor but that's different can of worms (oil?).

The Royal Purple that I use is their racing formula.

I mostly use the Racing 41 (10w40) except when I was running some 30# boost at the track, then I ran their Racing 51 (20w50). I can't tell any difference between the two so I will run the Racing 41 this year. Price is the same.

Re: Engine oil

From past experience, I would think that versus other conventional oils Rotella T would prolly rank #1 or damned close to it. I've never used it in one of these, but it kicks ass in other applications like 1,000,000+mi over the road trucks.

rotella t is more of a disel engine oil i believe

I think of Rotella as overbuilt oil for gas engines. But yes it is marketed for diesel engines. If you have a beater that burns the crap out of oil, Rotella T will stay in it better than anything I've ever seen.

It's real good stuff for alot of reasons so I keep 2 or 3 gal. laying around.

(no, I don't work for Shell)lol:)

That's what I used to run when I had trucks and wouldn't hesitate to put it in anything if Mobile 1 wasn't avail. Rotella is designed for turbo engines and will work fine in a car/PU especially if you don't want to run synth for some reason. I've just made the decision to run Mobile but for me it would be a tossup.
