Diesel Fuel Stabilizer And Performance Improver - Keeps Diesel Fuel Fresh For Up To 12 Months - Lubricates And Cleans The Fuel System - Treats 320 Gallons, 32 fl. oz. (22254)

Every fall I treat my diesel fuel and every spring the boat starts fine. Works for me.

Good product. I have used it before. Found it for a good price on Amazon.

I've been using this for about 50 gallons diesel by now. I've gone through one winter layup of about an 80 gallon tank and about to go my second winter layup on the same bottle. So far no issues I can tell.

It's hard to tell how well this stuff works. My bus starts when I wanted to even if the diesel is pretty old, so I guess it's doing its job.

very happy. worked well for its intended use.

Preserves diesel fuel saving lots of money. Best on the market

We have been using Sta-Bil For Diesel Fuel for a few years now on our stored fuel. Seems pretty high priced, which I don't like, but at 1 ounce per 5g can makes it fairly reasonable. I like the convenient quart size. Note there is a limit on time once the container is opened. Any larger container size, I would have a hard time using it up in a reasonable amount of time. I use it for storing about 70 gallons of diesel in 5g NATO steel fuel cans. I can not say for certain that it makes a difference but it is good piece of mind as I store our back up ranch fuel sometimes as long as two years.

my husband puts this in the 35hp tractor every year says it works good keeps fuel fresh will buy again

Happy with the results

Excellent product

Whats not to like? It works.

Great but Expensive

Pleased with purchase
