Customer Ratings & Reviews

Top notch product it works wonders on my 2007 4x4 V8 Sporttrac with 299,000 miles plus our 2020 Honda CRV Touring we use it with every fill up now there’s 10% ethonal . .

I run a bottle of this in the gas tank when I change my oil. Good preventative maintenance!

Great product.

Smooths out throttle response and give a little more pep. I'm not on the skinny pedal as hard which equals more mpg.

Makes a big difference

Great stuff. Brings back that quick start when I turn the key. This works better than Lucas brand.

Works in our vehicles year round,especially when vehicles are mostly driven in low speed town/city driving....

Use it every oil change and truck run like new.

Bought a old used Subaru and everything Amsoil is great so I added to the cart and gave it a shot! Can't hurt being a Amsoil product.

Just great products

I think this is a must, especially for ls motors that can have problems lubricating the top end.

My order arrived short, missing the oil filter and 3 bottles of gas additives...would like to get an eta for the rest of the products.

Seem to be helping with the mpg will continue to monitor. When your spending a grand a month on fuel you take what you can get

I have noticed that my injectors are functioning smoothly after the installment.

I purchased a case and have been very satisfied as both my vehicles are running great. However, my shipment showed up with an oil stain and when I opened the box I found one of the bottles cap was loose with seal broken and the fluid leaked all over the box. Then found a few more bottles with loose caps but the seal still intake.

This stuff is a great fuel additive. I've used it in three vehicles and the results are amazing. Regain in HP and smoother idle are easily noticed. Highly recommend.

Wanted an upper cylinder lubricant that didn’t effect gas mileage. So far, I don’t see a mileage difference from use/non use. Using at every fill up.

It poured in my gas tank with no problem

I use a bottle every 2.5k

As expected!
