AMSOIL Passenger Car & Light Truck Antifreeze & Coolant
Advanced and unique poly-organic acid technology (OAT) delivers fast-acting, long-lasting protection for automotive cooling systems. Mixed with high-purity water to prevent scale and deposits and keep your engine running clean.
Jeeps are picky, so finding out that I could use this AMSOIL product made me extremely happy! Nothing wrong with the OEM MoPar antifreeze, but being able to order everything together (oil, oil filter and such) makes everything so much easier. Also, knowing it’s an AMSOIL product gives me the feeling, I’m doing all I can do to keep my cooling system working properly.
It’s the best antifreeze on the market today I use it in my 2000 C5 Corvette also in my 2017 Mazda6 and “my 2021 Mazda 3 have no problems with any of my car’s to date.
I use this coolant in my Ram 3500 diesel. It runs 5 degrees cooler in the summer, verses the stock mopar coolant.
Bottom Line
Yes, I would recommend this to a friend.

I'm just going to say their name speaks volumes. Highly doubt that it's much different than others. But I use it haven't had any issues, works great and cost comparison to name brand on par.
Put this stuff in my wife’s car and my truck and so far so good. Had an issue with my truck where the fan wasn’t coming on and I was sitting in traffic and the truck didn’t even budge in the temps.
I have purchased 10 bottles of the AMSOIL 50/50 antifreeze and coolant . So far it’s done very well on my 4 Toyota Tundra’s . I plan to buy more and use it on all of my other vehicles for myself and my family. I’m already using the AMSOIL oil and I am very pleased with the results.
