As long as we are re-visiting the old oil debate...
My car has 69k on the odometer. 10W30 is what I use for 8 months a year. For the hot summer (racing) months, I usually switch to 10W40.

I was considering a new approach (like this weekend when I change the oil) and going with 10W30 for say 3 quarts, and straight 30W for the last 2.5 qrts. Rational behind this when the motor is running hotter, the straight 30 might provide the better pressure, and I would avoid the 40w oil which supposidly has additives...

Anyone out there have an opinion on this ??? (loaded question....)
