Don't bother looking for it because you won't find any additive that will net you 26 mpg. It just isn't realistic!!!

Stanadyne

I had something going on my engine light was going on, i was told I needed to change out at big expense I might add, had 3 mechanics look at this, 2 told me it needed changing the last one told me it might but its a more of a lubrication of the components what he suggested was STANADYNE PERFORMANCE FORMULA this additive well not affect warranty ... But the big thing is 4.95$$ fixed my regulator this new fuel has no lubrication put 2 bottles in the first tank just to get things going fixed me right up it has been 2 tanks now and no more problems...hope this helps...they are taking the sulfur out of the fuel the regulator need lubrication this new fuel is hard on are pumps and parts
