I haven’t looked for any differences but this brand was recommended by the people who rebuild my high pressure pump and XDP has a great price with stellar customer service!! Usually quick shipping as well, not much more one could ask for.

Only additive I use

I’m guessing this stuff works. No issues, thus far. I always buy from XDP because of their pricing. I use half of a bottle every fill up.

I bought this product because if you search for the highest rated it was first. I ordered it at about 11. Next day was my day off so as i'm at home, UPS shows up and hands me my package. Like who else does that?! Besides the worlds fastest shipping, It works like another addictive, Dump in when filling, enjoy the benefits. I fill up tomorrow so i can see if i actually get any MPG benefits

Frequently Asked Questions

Will this specifically take care of gelling during very cold weather? If not, what is availble for the gelling problem?

What happens to the Stanadyne additive if it is stored below freezing? Should I get rid of it? I left the bottle in my truck and the temperature got down to around zero. I don't want to use it if it will cause a problem.

Stanadyne fuel additives will freeze in their concentrated form but not once they are added to the diesel fuel. The additive can be used as long as it is not frozen. If you see that the additive has frozen, bring the additive indoors to return to its normal properties before using.

How often should I use Stanadyne diesel fuel additive?
Stanadyne diesel fuel additive is typically recommended for use with every fill-up, or at least every few tanks, to help maintain peak fuel system performance and prevent potential problems. Recommended treatment is 4 ounces of performance formula per 15 gallons of fuel. A common guideline is to add one 8-ounce bottle for each full tank of diesel fuel (depending on the size of your tank).
