hey folks! I've been a CK5 guy for a long time, and now I'm here with some solutions for you, to overcome the effects of the EPA mandated changes to diesel fuel, gasoline, and engine oil.. there's a lot going on that will affect you, and as you might guess, the engine manufacturers, and the fuel and oil companies don't have much reason to help you out. You can click on the vendor link in my signature for the scoop. I appreciate the time, and look forward to working with you. Tom
