Planning on doing a coolant change in my sti but i am unsure whether i can dilute the coolant. It's the motul inugel expert (green) coolant. Anyone else running it in their cars?
I've never used it as I just daily my car so I use the OEM stuff but some dilute whereas others are ready to go. I see you're driving an STI so you may want to use better stuff if you're pushing it a bit. Don't get rid of the bottle when you buy more, then you can read the instructions
