Review: A must for Diesels - I have been using this additive for my Diesel car for ages. I have noticed and Mechanics remarked how clean and efficient my engine had been.
Review: Techron is the best - I’ve used the Chevron Techron gasoline cleaner for many years. It’s incredible stuff, far and away the best such product on the market in my opinion. This is my first time using the diesel version. My 2002 Cummins was running fine, but this seemed to noticeably smooth it out. Still only a few gallons into the tank, but I’ll be buying some for my 2014 BMW 535d.
