In Puerto Rico, where high temperatures and humidity put cooling systems to the test, having a reliable coolant is essential to protect engines, machinery, and vehicles.
Among the safest and most consistent alternatives on the market is 50/50 coolant, a solution designed to provide thermal stability in hot and temperate climates.
At American Petroleum, we have our own line of lubricants, American Quality Lubricants (AQL), recognized for its quality and competitive prices. Within this catalog, we offer 50/50 coolants designed to provide reliable protection and stable performance in all types of operations.
What is a 50/50 coolant or 50% coolant?
A 50/50 coolant is a pre-balanced mixture of 50% deionized water and 50% ethylene glycol (responsible for raising the boiling point and preventing freezing), which improves thermal conductivity and prevents mineral buildup.
This ratio offers key benefits:
- Greater thermal control.
- Protection against corrosion, rust, and cavitation.
- Chemical stability that prevents damage to radiators, water pumps, and hoses.
By not requiring additional mixing, 50/50 coolants help standardize maintenance processes and significantly reduce operational errors, especially in fleets and workshops with high service volumes.

Types of 50% coolant we offer at American Petroleum
American Petroleum offers two variants within the AQL catalog, both pre-mixed at 50% and available in different formats:
AQL Full Strength Coolant 50%
Available in 3/1 gallon, drum, and tote sizes. Provides reliable protection for vehicles and equipment in regular operation.
Full Strength coolants offer standard, reliable protection, ideal for vehicles and equipment that follow regular maintenance cycles. Their formulation is designed to maintain a stable operating temperature, prevent corrosion, and protect cooling system components under normal conditions of use.
AQL Extended Life Coolant 50%
Available in 3-gallon (3/1), drum (55 gallons), and tote (250 gallons) packaging. It is a long-life formula designed for modern engines, intensive fleets, and machinery subjected to continuous operation.
Extended Life coolants incorporate long-life technology that extends service intervals (less changes), reduces shop visits, and optimizes operating costs. Its advanced formula improves thermal resistance, protects against cavitation in heavy-duty engines, and keeps additives active longer.
They are the ideal alternative for modern engines, intensive operations, continuous-use machinery, and fleets seeking to maximize maintenance efficiency without compromising system protection.
