    Changing viscosity on an older engine?

One thing--the oversized tires make fewer revolutions than the stock tire size, so you're odometer is registering fewer miles than you actually travel--that makes your miles per gallon calculation look...

    Originally Posted By: DuckRyder Isn't this a port fuel injected roller cam Mark VI Big Block (AKA Vortec 7400) and isn't the factory specification 5w-30? I think the first step would be to get a true and accurate baseline with the recommended grade of oil and and go from there. If you have...

    Originally Posted By: bullwinkle I would add a '99-'02 7.3 Powerstroke Ford or a Duramax to that list as well. I'm a Chevy guy, so the Duramax is definitely on my list of things to watch out for. I wouldn't touch any of the newer Powerstrokes, but the 7.3 is something I would consider if...
