"Got Triax Fleet Supreme 5W-40 from a local diesel shop, said it stops injector issues with the Powerstroke engines without the need for additional additives. They were right. Never used another oil since 2018, have had no more injector issues of any kind since then. "
"Without any doubt the best diesel oils I have used in my 30 years driving my trucks. Quiet engines, no injector issues, turbo spools instantly and after a night out at - 20 my truck starts without hesitation and to top it all off, got an extra 2 mpg on my fuel."
