I have 4 trucks on the road 6 days a week. I have my drivers put in 2oz of EDT with each tank of fill-up. I have had no injector problems and the trucks get better fuel economy then before.
Something wrong with this post? Thanks for letting us know. If you can point us in the right direction...

Great product. Been using it in every tank since about two months after I got the current truck. Noticable difference in engine noise, pick up and a bit of a bump in fuel economy.

This product will keep your injectors clean and give your diesel better mileage.

I don’t notice any improvement at all
Sorry to hear William, have you had a chance to contact us about our money back guarantee? I do see you had excellent results with the Diesel Extreme; so there’s a chance that EDT will not be as noticeable even though it is continuing to clean, lubricate and protect the fuel system.

Use this on every fill up in an 05 Duramax. I’m averaging 1mpg better mileage.

After the initial treatment and the use of edt. My 7.3 powerstroke has smoothed out mileage back up and no longer the need to replace the fuel injectors, the black smoke as cleared up engine running like a new one.
