Tried several types of additives and from what I’ve found this additive worked best for starting as well as most complete fuel burn noticed mostly at idle.
Great stuff 8oz goes in every tank full !!!
This did prevent my fuel from gelling, but it also made my MPG worse. Winter fuel itself makes your MPG bad, then add this & it made my MPG even worse. In order to gain back some MPG, id have to double the dose. No thanks. No need to use 2x the amount, or add Diesel Kleen to the mix & pay more. I’ll just use another brand anti gel fuel additive in the winter, that doesnt make my MPG worse.
