What about Pennzoil Long Life 15w40? There are some very nice virgin analysis of it here. Too bad there aren't any used analysis's of it. I'm considering using it this summer in my mostly autocrossed LT1 Camaro to clean up the varnish. Does anybody think it would be too thick for a chevy 350 V8? 30k miles on the engine but 8 years old.
How about Valvoline Premium Blue Extreme 5w40
Here it is at 16.10 per gallon.

were they pointing a gun a your head at the same time..!?!?!?!
Geez ..it's almost worth the drive to Ottawa...
Go to the CDNtire auto desk and ask for the perfomance catalogue. RP has a section in it.
The clerc phones the distribitor, quotes you a price (8.60), and if you decide to buy (a case of 12), it arrives 3-4 in working days, Probably faster in your area...

Jean, I will probably do that. I'll wait to see my wife's initial RP results first though, before I decide to commit to buying a full case again (over $100 worth of oil!)
Rob, I think the LT1 engine would do well on a high 30 to low 40wt oil, but unfortunately the Pennzoil 15w40 is a thicker 40wt at 15.5 cst, so I think it might be too thick to offer the best protection for your engine. If you're gonna go 40wt, look for something on the lower end, 12.5 to 14.0 cst if possible.
