Back to Mobil 1 synthetic for me :)

BT :cool:

Good deal BT you'll thank your self later :D :D

That is what I have always run Bobby, just trying something different. Hopefully I didn't hurt anything.

As a side note, I was just reading the back of the Mobil 1 qt bottle and it said it provides oil protection to 400F. :eek: :eek: That is definately superior to dino oils.

BT :cool:

Mobil 1
 

Call their free tech line and they'll back down significantly from that 400 deg. - brag!!!

But it is still head and shoulders over dino stuff......

P.S. - put Mobil 1 in a "waste oil" heater (like my local mechanic did several years ago) -and all it will do is boil and the heater will go out. (no heat) That should tell you plenty!

I'm running a 540 Carb engine that will see 290 degrees after a while at WOT, but when cruisin around 60 -70mph I wont see 200 degrees all day, Is 290 too high? I'm running striaght 50 weight valvoline.
Thanks Mike

I think 290 is too high. Oil can't take it from my experience.

BT :cool:

Oh man yes 290 is to high for the conv. oil !! is that after the cooler if so get a larger cooler ,,but its really to high for the oil itself ,cheaper bearings start to flake at 320 + or _ *
the good H series bearings it not a problem except to the oil you may get a thermo to stop the big temp swing and cut down condensation when it drops below the 190* point ;) ;)
