Stanadyne Diesel Fuel Additive Performance Formula All Season Protection, Half Gallon, Pack of 6

Great product if you want to protect around 2000 dollars worth of fuel injectors on your diesel. Lift pump, injector pump the entire fuel system. The low sulfur diesel that we all use has virtuality no lubricating properties. This stuff will lub em and protect. Stablizes fuel and has other performance benefits as well.

About the same price that you can get it at Rural King just got it shipped free

Use this product on my boat when adding diesel fuel. Does a good job and I recommend but I do think the price is a bit high.

I have used it for 30 years on three different diesel vehicles with no injection system problems. Volkswagen recommends it as THE diesel additive to use. Stanadyne is a manufacturer of diesel injection pumps, which gives them more credibility than a company that produces nothing but additives. This was the best price per ounce I could find.

This is a great product for your diesel vehicle. They need better packaging when sending to customer.

exactly what I ordered

I liked that you can order this Stanadyne like this , it’s a much better deal than purchasing it single containers , good price

I have nearly 200,000 miles on my Silverado 2500 Duramax. I've had zero issues with injectors. I change the fuel filter regularly and put Stanadyne in the tank with every fill. I'm still getting good mileage towing a 12,000 pound trailer. When not towing I get over 20 mpg. In a seven thousand pound 4 WD that's remarkable. I believe Stanadyne has a lot to do with the mileage. I got the tip to use Stanadyne from a couple of professional truckers who swear by the stuff. I'm a believer.
