Several studies have shown that on pre DEF trucks 6oz of two stroke oil to 26g of fuel yields an average of 1mpg. Experiment on your own with DEF approved additives and see for yourself. If you don't see an improvement, then they don't work for you and vise versa. I am a fan of them and will not go a tank without.
Go to a Cummins forum and ask this question. People with the same truck have much more experience than the ones speaking out of theory.
I have used WM 2 cycle oil for years. I sure would like to see a link to those studies that show better fuel mileage. Chris
