I wish they sold this in concentrated form. I flushed my system using distilled water and chemicals and then flushed the chemicals twice with distilled water before filling with AMSOIL coolant. There must have been some distilled water left in the block or heater core because after I was finished the mixture was only good to +10 degrees. Not a good thing in Minnesota but will suffice for the summer. I will have to drain in the fall and refill though to bring that mixture back where I need it to be for a Minnesota winter. If I had a jug of concentrate I wouldn’t have to drain as much and this problem could be easily rectified. Other than that I love the product.

First use. Water temps are a few degrees cooler especially when idling. Spills didn't leave any resudue. Superior performance and lasts forever. I'll never use anything else!

Can you send me a bottle of your Dominator boost, so I can beautify this review?

I have a Dodge 2500 diesel, Mopar's antifreeze is quite pricey. I have confidence in Amsoil products. All vehicles in this household use Amsoil oil, motor and trans!! Keep it up!

My truck runs 10-15 degrees cooler. Towed 5th wheel 2000 miles round trip passing through the Appalachian foothills. Temperature would rise while climbing but would quickly return to normal. I use the gear oil, diesel oil and diesel fuel treatment as well, no gauge to monitor temperature difference. The diesel fuel treatment improved my towing gpm. The coolant and diese fuel treatment is impressive no reason to doubt the benefit of the gear and engine oil.

👍 goes in everything I own

it works great for my motorhome

My truck needed this (flushed), It worked out perfect, I did notice my truck seems to run a few deg cooler.

Great product and quick delivery....works as it should

Recently serviced my Kubota BX 1860 using this coolant. It is a pre-mixed product which is very handy. Expect it to last another 8 years/1000 engine hours.

Using this in very costly important equipment. Always trusted Amsoil so trusting in this product. Hard to justify the cost as other manufacturers have longer warranty’s now my boss has said. My carpet ride I’m hoping will not pull out from under me.
