To ALL of you who helped me make my decision final...
You guys really helped me, and thanks for all your time.

After reading all 10 comments to my question about oil consumption, I decided to go with Pennz. High Mil. 10w30. I'm going to change oil today.

Anotyher question: Pennzoil High Mileage 10w30 is 12 cSt, Pennzoil High Mileage 10w40 is 15.5 cSt...
If I mix 1 qt of 10/40 with 4 qts of 10/30 what weight would it have? is it even ok to do it?

Mixing doesn't always produce results as predicted though, it depends on the different VII in each oil.
