Re: [A/S] Oil Change Suggestions?





I can only speak from my own experiance, I have a '91 Dodge/Cummins that I
bought new, it now has about a quarter million miles, I have always used
Castrol GTX 20-50w (I live in Texas), this truck still uses no oil between
changes and will still peg the boost gauge I put on it at new at 30psi
