Rated 5 out of 5 by from Awesome!! I use this in my 2015 dmax to help my cp3 I didn't know anyone local carried this till I found it walking the aisle works as expected and I don't have to drive 30 miles to AutoZone and the prices are better here

Rated 5 out of 5 by from Works the best Im new to diesel engines with both my Ford 6.0L and in our skid steer. We live in a very cold/snowy area during winter months and while both engines have engine heaters we see temps. down to -20 if not colder. Any ways, Ive tried a couple other treatments for anti-gelling (had to buy in a pinch) and both other products failed and left us down a truck and/or a skid steer to plow with causing us a lot of headaches! Will use nothing but this, we've never had a starting or gelling problem using this product. We now keep a couple of the larger containers on the shelf at all times during winter just so we don't run out.

I have two 19 gallon tanks in my F350.  How much of this product should I use per fill up?

Asked by: klcair99
The 16 oz bottle of #38565 will treat 60 gallons of fuel. Every ounce will treat 3.75 gallons so 5 ounces per tank will suffice.

I’ve used another brand of additive. I’ve heard good things from Stanadyne and want to change over,do I need to do anything extra to switch over ?

Asked by: Mekc
The manufacturer has advised if this is a passenger size vehicle, you should be fine using up the fuel in the tank and then using the STAN on your next fill up. They are not aware of any compatibility issues.
