A Go-to Coolant for Porsche Owners
Rather than spending more on "Porsche" branded (even though they don't produce them), this is very popular amongst Porsche owners (and other German cars, as applicable). Used to fill low coolant, the same color as the existing coolant (not sure what previous owner filled) and cheaper than OEM. Would not hesitate to purchase another Zerex (blue) for other cars. Highly recommended.

What was needed for my Porsche.
This is the appropriate replacement coolant for my Porsche. I have owned it for five years and never topped up the coolant. It started to concern me, and I found that this was the most cost effective product to use in this case.Really good for the price. I feel confident using it in an expensive engine. Glad I bought it.
