I learned about BG when I was in Pittsburgh. I met a mechanic that believed in the BG name. He helped me see how BG could help me with my older diesel. He learned along the way because he wasn’t even a diesel mechanic but loved happy vehicles. With his help and that of BG, my truck came alive. I used this truck with conventional lubricants to haul our camper through the mountains and always saw higher temperatures (still within range). Once I swapped to BG, my temps dropped to the bottom of the operating range!
