I know that the Extra fuel from the TST will cause this but I am a little surprised that it got this black this quick! Have been running the TST on 2/3 - 3/3 and a few ahort runs on 5/5 playing. Wondering at what intervals you guys are changing your oil and what kind of oil your using running the TST. I just hate to change full synthetic oil out at 5k miles. If needed then I may just go back to regular Delvac due to the cost....Or remove the TST and run the truck stock.....NA! What fun would that be! Anybody else notice this?
