The coolant levels in my 2006 Subaru Forester seemed low so I was going to pick up Prestone pre-mix from the store and top it off.
The coolant in my car is blue. The manual says
SUBARU coolant or an equivalent: a mixture of 50% soft water and 50% ethylene-glycol basis coolant.
The Prestone package says compatible with all cars.
- Does that mean the regular Prestone coolant is fine to mix in with the blue coolant that's in there already?
- Is Prestone really compatible with ALL cars?
