STA-BIL Diesel Fuel Stabilizer, 32 oz | Treats 320 gallons. Keeps diesel fuel fresh up to 12 months and helps prevent sludge and water buildup.

Does the job. What I wanted.

Great product and fast shipping

I consider this a very good product. It does what it says it will do.

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.

If you plan to store gasoline or diesel fuel, always use the correct type and amount of Stabil. Rotate your stock every 6-9 months. Never store either fuel for a year or more. Store in a cool place.

Good stuff

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.

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

Happy with the results

Excellent product

Whats not to like? It works.

Great but Expensive

Pleased with purchase
