Customer Ratings & Reviews

Works great.

I use injector clean every time I fill my tank. The all-in-one is an easy way to keep the injectors clean and lubricated and to have the peace of mind that I don't have to worry about the fuel gelling. The added octane boost never hurts especially as fuel prices increase.

I have been using a soil products for several years now and have experienced no problems. It gets pretty cold in WI and my F-250 diesel has not once gel’d on me. So, this product must work.

Use product in 2015 VW TDI and 2021 Duramax. Noticed instant cold start operation. Was a die hard lucas oil products, but will only use Amsoil from now on.

It's nice to have all products in one bottle. Piece of mind in the winter with cold flow and cetane boost and injector clean to keep everything smooth.

Your a fool if you don’t use this

Have been a Amsoil customer for the last 30 years, love this product.

Love this product, notice the difference when starting at 20 below. Fires right up, with the other stuff I used, not so much.

When I use this about every 3 tanks I can tell the deference in fuel economy and power.

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
