Diesel Treatment?

If you can but B20 in it every once in a while. It cleans and quiets the Tdi. I only put Diesel treatment in mine in winter. I ran it on B20 all the time for a couple years until the station closed up. It really ranbetter with bio fuel.

Our older equipment and trucks definitely sound better on B20 lot less engine clacking. I ran B100 for a summer in my Duramax just to test it before we started to run it in our fleet. 0 problems until the colder weather came in the fall gels up real quick. As a bonus it really does smell like McDonald’s!

We use this now and have had good luck. I’ll probably throw a little in the Cummins ever other fill up.

Only issue with B100 in my experience is that it can swell seals and cause leaks On older high mileage engines. Happy my experiences with bio fuel are not isolated. Good stuff! And yah mine smelled of fresh made fries 🍟 :LOL:.

Do you think it was the B100 or the dirty particles that were dislodged from the B100 causing the problems. B100 scours old fuel lines when we run 50/50 in our older trucks we have to change fuel filters every tank. Can‘t believe how much crap was in the old system

The problem is any nitrile (Buna-N) in the system. Biodiesel attacks nitrile most o-rings and seals are nitrile. You need to change to Viton seals. The stock nylon fuel lines are fine.
