Judy H.: Been using Stanadyne product in my '97 Dodge 3500 for 23 years, 232,000 miles. Never had any fuel or injector problems. Use it year round. But only use a small quantity (25%) of winter recommendation. It is a great cleaner/lubricant in the summer. I think it also helps fuel mileage. 20-22 in town and 25-26 on the road. Definitely recommend.

Robert J Davis: I noticed a significant difference in the smoothness of my diesel engine idle and performance when using this additive. Buying in this bulk sizing is also a great way to save money. My only complaint - I have to carry a graduated cup / beaker to measure correct dosage amounts. It would be nice if the container had an ounces marking on the container.

LINDA MASLANKA: We use this as a regular maintenance item. Haven't noticed a huge difference, but the engine does run smoother and it did increase our mileage a bit.

Matthew: Comes highly recommended by the old timers!
I put a slug in the tank every other fill up and you can feel the difference in idle.
Makes the 7.3 clack a little less!
No miracle juice but then again it’s really made for a mechanical high pressure pump, so maybe in a 5.9 you could tell a better performance gains?
