Stanadyne Performance Formula Diesel Fuel Additive 3 Pack of 1/2 Gallon Jugs - Part # 38566

Use with every fill up. My truck is a 2003 GMC and still going strong. No engine problems.

Product improves Cetane and my engine operates much smoother. Provides lubricants needed for my diesel engine. Good value based on additive to fuel ratio. Improved my fuel economy.

great for diesels

Works all year round. No fuel slushies

When I first bought my 99 Dodge Ram pickup a Diesel mechanic told me about how this product should become a part of my maintenance program. Been using it since that day and I get GREAT MILEAGE plus the engine runs smooth and I've not had ANY major repairs or issues to deal with. Just add it to your fuel tank every time you add fuel and your good to go. EXCELLENT PRODUCT. Just wish they still sold it in the smaller translucent bottles as it had the marking on the side indicating how much to add each time. Easier to carry on my truck as well. Hope they bring the smaller bottle back . . cause I won't be without my truck's favorite additive.

I saw a review where this product has lubrication which my turbo needs with this extra dry diesel they sell today. Working great, increased mileage, and increased performance. I would not run without it. It sounds like it set my turbo free to perform as it was designed.

Llevo años utilizando este aditivo y los equipos responden bien, lo recomiendo.

Like having the convenience of not running out. It is a bit of a pain refilling 8oz bottles (which are easier to use of course) and feel we leave a smaller footprint.
