I had received the strips but had time today to do it but could not test the coolant as there wasn't enough to test.
Can I use coolant that I bought at a local store instead of going to a BMW dealer? If so, is there a special coded coolant I have to buy and how much should I be buying? Can I buy a 50/50 premix?
