Allright would this product work well in a sludge proned engine (2.7 dodge). I have done an auto rx teatmeant. Would really like to run a sythetic in this engine to combat the heat. I was wondering how long I could go safely on mobil 1 with lc. My main goal would be to prevent sludge. dyno and maintane of auto rx is an option, but I would like to look at all options.
