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

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.

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.

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.

Excellent and does the job well.

Best diesel additive you can buy!! IMO of course!!!

Use Al the time. Good price and service.

The smelliest stuff around. Keeps my engine running great!! Highly recommend for all Diesel vehicles.
