Pennzoil Multi-Vehicle Extended Life Antifreeze & Summer Coolant
Pennzoil Multi-Vehicle Extended Life Antifreeze is an ethylene glycol formula that offers universal compatibility with engine coolant systems for all cars and trucks. The service life of this product is rated at 5 years or 150,000 miles driven, requiring fewer changes. The chemicals used by Pennzoil for this engine coolant do not react corrosively with other antifreezes, which prevents problems from mixing or topping off old coolant, whether that coolant is conventional or an extended life formula. This antifreeze is given a slight yellow dye so it can be added to older antifreeze without changing the color drastically. This product has an extremely high boiling point of 345 degrees Fahrenheit for superior protection for all engine metals at high temperatures.
