I picked a brand of diesel that does not need nor recommend to put anything in the tank except clean #2 diesel. That is what I do so no added expense for me.

More fuel mileage,more power,=more cost, you know that going in..but you find the trade off worth it,but,not for all....thats why they make so many different makes,models. And, I use the Ford cetane booster
Count us in. We use it on the smart cars. They run a little quieter and seem to perform a little better. The little Mercedes motors were designed for european fuel which has higher cetane levels.
