Thanks.

There probably are 1000 different opinions on this subject. Jerry

I use 10w30 in central Kansas it works best I think. But whats more important than the oil viscosity is the COLOR. When I have a drip on my concrete, I want to know what it is.. brake fluid, tranny fluid, whatever. So, Royal Purple 10w30 synthetic. Problem is, I don't have any leaks so far! Here is to hoping my problem persists! | | | | | Joined: Sep 2004 Posts: 241 'Bolter | | 'Bolter Joined: Sep 2004 Posts: 241 | I'll stick with the 10w30. Been using it since I got the truck. So far the only leak I've had (knock on wood) was from the oil canister due to a bad gasket. | | |
