Can you use Prestone antifreeze in a Subaru?
The short answer is no, you should not use Prestone antifreeze in a Subaru vehicle. Subaru recommends using a specific type of antifreeze that is compatible with their engines and cooling systems. Using the wrong antifreeze can potentially cause damage to your Subaru's engine and other components.
Antifreeze Compatibility for Subaru Vehicles
Subaru engines are designed to work best with a specific type of antifreeze, known as Subaru Long Life Coolant or Subaru Super Coolant. This antifreeze is formulated to provide the proper level of corrosion protection and lubrication for Subaru's unique boxer engine design. Using a different type of antifreeze, such as Prestone, can lead to compatibility issues and potential damage over time.
Risks of Using Prestone Antifreeze in a Subaru
There are several reasons why you should not use Prestone antifreeze in a Subaru:
- Incompatible Additives: Prestone antifreeze contains different additives and chemical compounds than the Subaru-recommended coolant. These incompatible additives can react with the materials in Subaru's cooling system, leading to corrosion, deposits, and other problems.
- Reduced Lubrication: Subaru engines require a specific level of lubrication in the cooling system to prevent wear on critical components. Prestone may not provide the same level of lubrication, potentially leading to increased wear and damage over time.
- Voided Warranty: Using a non-recommended antifreeze in a Subaru may void the vehicle's warranty, as it could be considered improper maintenance or modification.
To ensure the longevity and proper operation of your Subaru, it's essential to use the antifreeze recommended by the manufacturer. Consult your owner's manual or contact a Subaru dealer for the correct antifreeze specifications for your vehicle.
