Additives included in MPG
 

Is there any way to account for additives? I regularly use powerservice diesel additive, and it makes a small MPG difference if it is not accounted for.

You could always add a note or special tag when you add an additive. Those are the built-in ways we have to track things that might affect your fuel economy.

Yep, I just put it in a note or when i fill up what additives I use or not.
