Passenger Car & Light Truck Antifreeze & Coolant

The simple solution. Compare to other Antifreeze products available in the Omaha area. Break-through technology – see below.


Perfect Scoring Premixed Antifreeze Coolant – Passenger Car Formulation

To really understand the advantages of this coolant one must understand the shortcomings with all the major formulation types available. What AMSOIL has done here is correct the issues between the OAT and HOAT formulations. The initial goal was to build a coolant/antifreeze which lasted longer but addressed the corrosion and rust issues in the cooling systems. If you need a HOAT based product check out our Heavy-Duty version for over the road trucking. (It’s often used for our vintage car customers as well)

We also have a low-toxicity version which is even better if you work on your own cars to avoid the issues of the Ethylene glycol. More on compatibility below. 

• Unique poly-organic acid (OAT) formulation imparts multi-vehicle application
• Engineered to exceed original equipment manufacturer (OEM) requirements
• Protection up to 150,000 miles or 5 years, whichever comes first
• Ethylene glycol 50/50 pre-mix formulation
• Protects all cooling system metals, gaskets and hoses
• Phosphate-, nitrate-, nitrite-, silicate-, borate- and amine-free
• Compatible with all other antifreeze and coolant colors

In third-party, industry-standard testing, cast-iron and copper plates protected by AMSOIL show virtually no signs of corrosion. See what we’re saying? Your car needs this before it’s too late.

Help Prevent Metallic Corrosion and Erosion

Independent tests reveal AMSOIL Antifreeze/Coolant greatly surpasses standards for metallic corrosion and erosion, achieving nearly perfect scores in ASTM corrosion and erosion testing on cast aluminum cylinder heads, steel, copper, solder, brass and cast iron and aluminum water pumps.

AMSOIL Antifreeze Resists Corrosion To The N’th Degree!



AMSOIL Antifreeze/Coolant is a poly-organic acid formulation that does not contain inorganic acid salts (phosphate, nitrate, nitrite, silicate, borate, amine) found in conventional and hybrid organic acid (HOAT) antifreeze/coolants. These materials are responsible for almost all scaling issues in cooling systems, and they can also precipitate to form scale if the antifreeze/coolant inhibitor system is at the wrong pH or mixed with incompatible products. AMSOIL Antifreeze/Coolant virtually eliminates scaling problems.

Long-Life Formulations

AMSOIL Antifreeze/Coolant does not contain inorganic salts that deplete over time and turn into scale deposits. This unique blend of organic acids provides durable and long-lasting protection of cooling system components. Passenger Car/Light Truck Antifreeze & Coolant can be used for 150,000 miles or five years, whichever comes first, in passenger cars and light trucks.

Compatible With Other Fluids

AMSOIL Antifreeze/Coolant is compatible with all ethylene and propylene antifreeze and coolant colors, as well as all plastics and elastomers (hoses, gaskets, etc.) found in cooling systems. However, mixing propylene and ethylene glycol formulations can make it difficult to predict freeze protection. If mixing for top-off is unavoidable, it is recommended to flush the cooling system at the next convenient opportunity. If you have over 60,000 miles or 2 years on a coolant, flushing before using this one is your best bet.


  • Engineered to exceed original equipment manufacturer (OEM) requirements.
  • Pre-mixed 50/50 with high-purity water.
  • Unique poly-organic acid formulation imparts multi-vehicle application.
  • Phosphate-, nitrate-, nitrite-, silicate-, borate- and amine-free.
  • Boil-over protection up to 265°F with a 15 psi radiator cap.
  • Freeze protection down to -34°F.

Directions for Using the Premix Antifreeze/Coolant

  • Do not add water.
  • Do not remove radiator cap when engine is hot.
  • Antifreeze/coolant (new or used) is hazardous. Clean up and dispose of properly following local regulations.
  • Check and maintain coolant level at every oil-change interval.
  • Check owner’s manual for maintenance and top-off guidelines.

Coolant and orders in general
By  DAVID,  a  Verified Buyer  from  Orlando FL  on  April 13, 2022
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
Great product

By  Gwgdog66,  a  Verified Buyer  from  OKC  on  January 03, 2022

Good product, vehicle is running well and not overheating with this coolant
Longest lasting coolant on the market

By  MICHAEL,  a  Verified Buyer  on  October 06, 2021

Fewer coolant changes saves me a lot of time and money.
Noticeably improved heat transfer.

By  DAVE,  a  Verified Buyer  from  Cleveland, Ohio  on  June 02, 2021

2014 Honda Accord 2.4L 102,000 miles Drained factory Honda coolant, which is extended life 150,000 miles / 10 years. I keep a log of my mileage and maintenance and average around 35.5 mpg highway. I immediately noticed what seemed to be improved highway mileage with improved acceleration from 80-100. After 800 miles over a 4 week period I have an increase of ~4% or 1.4 mpg. This is driving the same course to and from work as prior to using Amsoil coolant. Another words comparing apples to apples. Being an engine developer from the muscle car days I was fascinated on how this could be. Better thermal efficiency does translate to more horsepower, but usually not that much of a mileage improvement. What I found does explain the result in such a mileage improvement. The answer – the dual cooling fans taking longer to come on and running less once they do. Less electrical draw and engine output needed for the same driving condition. For someone who keeps their vehicles hundreds of thousands of miles, as I do, better heat transfer means less friction resulting in less wear & tear resulting in engine & transmission longevity. Here is some real technology. Whoda thought there could be such a difference in coolants. My hat off to the Amsoil team. It is a real pleasure & surprise to find a product that delivers and isn’t just sales verbiage. I am currently road testing their CVT transmission fluid in the same vehicle.
