Keep using it (1/25/2021)
I've been using Fuel Max since 2007 in a 98 Kenworth W900 with Detroit motor. Within 2 3 weeks I noticed much better pulling and increased mileage. I was able to pull 1 million 400,00 miles before rebuild. Mechanic was impressed as to how clean top of pistons and head were. Exhaust system was also nice and clean with no build up. He told me - whatever your using keep using it!
