Should i be adding some fuel additive with lubricity for the cp4.2 pumps? i know there is alot of hype about the past issues with the cp4 and dont want to get into that at all.......just curious if it may help and if so whats the best. Ive always ran power service for cold weather but not with the intent of added lube.
