My truck has 81,000 on it and I have never run any type of injector cleaner before. I bought the Rotella DFA and it says 32 oz for 100 gallons of diesel. Would it hurt anything for me to pour in all 32 oz in my 35-gallon tank? The truck is running like a top so there is no problem there and I don't need to worry about my fuel gelling. Any info would be appreciated.

 

I would stay with the recomended amount from the supplier. 32oz. for 35gallons seems awfull high to me. :-X

 

I use DFA every tank in the winter. I only use the amount recommended by the manufacturer. I know it's time to start using as my milage drops off.

I add to every fill up in winter/summer every 2 or 3 fill ups.

 

Thanks
