Anyone using regular gas in a CLK 320?
What is your question?
Car says premium only, but several folks have told me if it doesn't knock, then regular won't hurt it. Anyone running regular gas with no issues or has anyone run regular gas and had issues? Thanks!
I've been running my 1999 CLK320 Cabriolet on regular gas since I bought it about a year and a half ago. The previous owner told me he never used premium. 87 octane is fine, I have no problems and get good mileage, about 24 mpg overall.
