This just goes to further prove that thin oils are for CAFE ONLY and thicker does protect better,or else it'd say "For track or competitive driving,use Mobil 1 0W20".
Yes but that said, the corvette engines, while impressive, arent particularly power dense.
They are V8 engines. 6.2L, 450-650hp or so...
That's 72-105 HP/L
My Honda Accord Hybrid puts out 70.5 HP/L... Should I run M1 15w-50 in it when Im going to be driving fast/hard on the interstate???
My 135i puts out 100 HP/L. It requires an LL-01 oil. It also has known high oil temperatures. Should I take that up to a 50wt for driving fast from stop light to stop light?
But,GM and Ford is "requiring" a 50 weight. Now if Honda (or the maker that mfg's your 135i requires a 50 weight) then yes,you should use it. Maybe those makers aren't marketing those two cars toward's grass roots racers like GM and Ford does their hi po cars. The Focus RS requires a 50 wt too. Every Corvette and Mustang driver I see always beats the heck out of their cars.
