Im using power service. what is the amount to add to a full tank of diesel on our trucks. I want to make sure I have the right amount cause that stuff is expensive. I know extra wont hurt anything I just want to add the right amount. We have what? 34 gallon tanks on the 05? Thanks in advance.

 

It should say on the back of the bottle but I think it's 1 quart for 125 gallons of fuel which would be about 10 oz. per full tankful.

 

Thanks for the info. I have been putting in about the right amount, ive been putting in 12 oz.
