We have a work truck, a 1999 Mercedes ML-320 tha calls for 91 octane. I'v filled it countless times with 87, never a ping, just less power but not even tha noticeable. Now before a one says I will ruin my engine, it has 193,000 miles on it and does not burn any oil and there is no valve noise. All about the electronics monitoring timing.
