If you can manage the cost , it's well worth it. Especially if you plan on keeping your vehicle(s) for many years.

I've been using Amsoil in my dodge diesel for 7-8 yrs now, I just feel better knowing my engine will run a long time, 233,000 on it now. This antifreeze is for an Audi Q5 we picked up two yrs ago. I've changed the oil and filter twice with Amsoil and will continue to do so. This Spring I will change coolant along with all hoses, thanks Amsoil!

Good quality

I have been using ansoil products for year . They are all high quality and sure to satisfy. Orders are filled quickly and accurately.

Fast and intact delivery from Ams oil. Perfect alternative to dexcool, long service intervals. A++++

Just picked up a '92 Mazda MX-3 GS which needs some cosmetic TLC and it is not currently running. I know it will need all the fluids replaced after sitting for 16 years so this coolant is for the all aluminum V-6.

Will defeat all comers! Get it or settle for 2,3,4,5,6,7,8 place!

Awesome coolant and convenient that it's premixed and ready to use no messing around

Excellent product, this is what I used in all my Toyotas...

Like I said "IT'S ANTIFREEZE". It meets the special requirements for my Ford, Mazda, Cadillac and Jaguar cooling systems. The color is different however. Jag says their approved antifreeze is red. The Mazda says theirs is a different color. As long as the Jaguar and Mazda specification compliance identifier IS listed, I'm OK with the Amsoil product. The pre-mixed formula is convenient when filling a totally empty cooling system. On the Jag, I would have to take half of the engine bay apart to fully empty all the coolant. Because of that I would like to have a container of non-pre-mixed coolant so things can be adjusted.

Wonderful

Does it’s job keeping diesel motor cool.

So, so start off I replaced my coolant in my car which I just got and it has 137k on it. Pitch black coolant. It was gross. Used Prestone Total Cooling System Cleaner. I ran distilled water through the system till it was clear then put another cleaner in it and repeated the process. Threw two and a half gallons in my system and when I start up my car it gets to temp a lot quicker and it stays cooler.

Same deal. Weather built or stock cooling systems this stuff works great. 90 degrees out on the track able to hot lap drifting!!!!

I have a 2000 Jeep Cherokee with 160,000 miles. Recently, I pulled the engine to replace all the gaskets and seals. I decided to replace the water pump while I had the engine out of it. I'm 69 years old and have been doing this since I was 15, and I have never seen anything like this. The insides of the water pump and engine block looked nearly new. We were dumbfounded. I'll never again use ANYTHING else.

I changed out my radiator and filled with Amsoil coolant and its a great product and at a great price.

I've been using Amsoil for around 25 years and it's never let me down, all my vehicles are running great.

The coolant and oils and additives I have ordered over the past few years have always arrived in a timely manner and as always exceeded my expectations. Just the peace of mind of using the best in the industry are enough to make me keep buying Amsoil products. And the price with the membership isn't any different than I was paying at the local Parts store, plus they are shipped right to my door. I recommend Amsoil to all my friends

Trust Amsoil. They are Quality.

Holding steady at 180 degrees with 180 thermostat, can’t ask for much more than that. Time will tell.
