Re: Which oil do you use
Why is 10w40 so popular?
GM said 10w30. Ya know, they're really smarter than we give them credit for...

But also, I would think motor oils now are way better than in the early 90s. But this is an endless conversation, I think it boils down to preference, easy of availabilty, price as well. |

Re: Which oil do you use
At the moment I do test the Valvoline VR1 Racing 10w-60 Premium Synthetic Blend Engine Oil. It also has zinc.

Re: Which oil do you use
I'm thinking about switching to Quaker State ultra, it has the highest wear protection by far

Re: Which oil do you use
http://www.amsoil.com/shop/by-produc...?code=AMOQT-EA
https://www.amazon.com/Mobil-120770-...0+high+mileage What is the thoughts of running 10w-40 in the Corvette vs. the normal 10w-30? I am worried that the thicker oil will cause issues down the road such as oil pressure or seals busting out? Am I just paranoid or what?
