Excellent coolant for Porsche
I could not find suitable coolant at the local auto parts shop or online, so I was very happy to find this coolant for my 911 turbo.

Good Stuff
Pretty cheap considering its concentrate. It’s the right stuff for VAG cars. not sure about mercedes or bmw. This one doesn’t degrade with heat from EGR systems or have other weaknesses OE fluids have.

Perfect for my VW Beetle
This product works with my 2013 VW Beetle. However - don’t forget to dilute the product with water (read your car specs for water to coolant ratio).
