It REALLY WorksBy AARON, a Verified Buyer from Oregon on May 22, 2026I have a 2022 Chevy Silverado 1500 3.0l Duramax with 48,000 miles on it. It was averaging 26.1 miles per gallon since new. At around 45,000 miles the MPG started dropping off and got down to consistently being in the low 25 MPG. The dealer told me it needed to have the fuel system cleaned and I bought a $75 bottle of GM’s diesel fuel system cleaner. Most of that ended up on the ground by the way; you have to use the little funnel that comes with the truck if you want to use a fuel can or an additive like I was doing. Anyway, that made zero difference, the MPG kept dropping. I decided to try the Amsoil additive, around $6 a bottle. The instructions said add 2 bottles the first time and 1 bottle there after when filling up. After the fourth bottle my mileage was back and even better than 26.1. I am now consistently over 27 MPG. It’s no joke, the stuff really works. I also use Amsoil for my engine oil, oil filters, and fuel filters. Prices are great and quality is second to none. Super happy with Amsoil products.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Trust It's ContributionBy ADAM, a Verified Buyer from Santa Fe, NM on January 24, 2026I keep it handy in door cubby of my 2019 Sprinter 4x4 and use it on every fill. Does 'seem' performance has improved on acceleration and power up hills. Feels trustworthy in that sense. After one month of use, have not yet seen any improvement on fuel efficiency (I've been diligently tracking that for over six years now).Bottom LineYes, I would recommend this to a friend.Was this review helpful?

It makes a noticeable difference on the 6.6 with fuel economy and surge in the idle it also helps both in cold temp starts.
