STP Ultra 5 in 1 Diesel Cleaner review: keeping your diesel heart beating
This cleaner is an excellent maintenance tool for anyone wanting to keep their diesel engine running smoothly without a mechanic visit. It effectively cleans injectors and reduces carbon buildup, though owners of capless fuel tanks might find the bottle design frustrating to pour.
