I love this stuff. It really helps protect my equipment in a full 360. It even help protect when it gets a little cold… 10°. It really is a dump in and don’t worry at all, all in one that actually does what it says it’s gonna to do. I will be using this till I go to the winter anti-gel protectant from Amsoil witch also works great and has protected my equipment down the -30.
Thanks for a great product like all your other products.
This stuff works great and worth the money without question!
Bottom Line

After a few hours of adding to the fuel I noticed that there was hardly any smoke out of the exhaust when cold engine on my farm tractor. Also seems to run smoother.
I used this during the crazy texas winter freeze and I was the only one that didn't have my diesel freeze up. I told several neighbors about it and they didn't believe me until their diesel gelled up and froze. Then they seen me driving around like it was just another normal day.
Bottom Line
Yes, I would recommend this to a friend.

Antifreeze

I've been using Amsoil Diesel All-In-One for 2 years. The improvement in gas milage just about pays for the cost of the product. And living in northern Wisconsin we've had plenty of -20 to -23 degree nights. I've never experienced any jelling. All-In-One does exactly what I hoped it would. I use it in every tank.
My only complaint is my tank is so big it uses whole bottle every fill up. Gets pricey compared to archoil that's highly concentrated and does nearly 500 Gallons
Bottom Line
Yes, I would recommend this to a friend.

I just started using this product as I now own a 2021 Volkswagen Golf TDI.
Very happy with the results. 👍 I also switched it over to Amsoil in the crankcase and transmission.
Been using this stuff in my F250 6.4 diesel since 2014. Now with 275,000 miles I have (knock on wood) never had any kind of fuel system problems. So, in my opinion it does a very good job of keeping the fuel system clean and lubricated. Thanks for another great product.
Bottom Line
Yes, I would recommend this to a friend.

Bottles fit great in the corner pockets of my Decked system. My Duramax is running a lot better the more I use it
