Antifreeze

Low-Toxicity Propylene Glycol Antifreeze

Provides Effective Heat Transfer and Enhanced Corrosion Protection Formulated with proprietary tiered surfactant technology, providing quick and effective heat transfer inside radiator and cylinder heads, which results in reduced operating temperatures, more efficient operation, increased horsepower and significantly reduced engine warm-up times in cold weather.

Available in packs of 6 or 70. Use PACKAGE SIZE drop down to select quantity. AMSOIL Antifreeze Test Strips have two different pads on them and test all but RED coolant. The lowest reports the freezing and boiling (under pressure) protection level. The upper pad reports the pH level and shows a pass/fail area. No other testing is recommended or required. The test strips are the only way a mixture of ethylene glycol and propylene glycol can be checked for freeze protection.
