Valvoline/Cummins Synpower additive
Just tried that stuff yesterday for the first time. Got it from Cummins, and although it's meant mostly for big rigs buddy at the parts counter said tons of people use it in Dodges in small amounts. I'm a big time believer in Stanadyne, but this stuff makes Stanadyne smell like cologne. So far so good, anybody else use this stuff?
