Customer Ratings & Reviews

I tried this in my 2018 GMC Duramax and within about a quarter tank I could notice an increase in HP. After a half tank I was getting an additional mile per Gallon. I haven’t gone through the entire tank of fuel yet, but so far it’s been very good.

I like this size as it is half of my tank is what it treats. I’m one of those that never goes below half a tank. This works perfect for me. I like the fact that I only run one treatment all year long.

This has increased my mpg and made my diesel run smoother and start smoother. I have noticed an increase of 2 mpg in my 2019 Ford . The increase in cetance also make the vehicle much more responsive. We are in the early stages of winter and have had a couple of 2 and 3 degree days. No fuel gelling.

Stuff really works after 2 bottles I noticed a diffrence with smother starts and runs a lot smother

Love that this product provides everything my 7.3 IDI needs. Keeps things running smooth. I trust Amsoil products and this one is always in the truck.

Like that it comes in a smaller package,but it’s only good for 20 gallons,wish it would treat 30 gallons for most pickups have.

the product seems to work okay but it's way too inconvenient to obtain. it's extremely expensive compared to other products in its category and as a Hotshot trucker Howe's diesel treatment and is everywhere at every truck stop and at a third of the price.

Great product as are all the others that they produce.

First time user of this All-In-One treatment. Didn't notice a performance improvement on first tank after adding it. The second tank of fuel, however, there was an improvement in fuel mileage on my F350, from about 17.5mpg to 18-19mpg. No fuel related issues due to freezing weather (lows at or below zero).

Great product, use all the time in winter.

Have had no gel up problem. Would highly recommend this product over others that I have tried.

Add before you fuel, While at station. I had no issues on super cold days. follow mixing instruction. Will buy again. Make sure your fuel filters are replaced before winter. 6-0 powerstroke 2006 f250.

Have used this product for several years in trucks, tractors, and an ATV. Never have had an issue with gelling or fuel system cleanliness.
