MTI and SLR2098:
There is a warning in MB owner's manuals issued in countries where gas quality and availability is errant. The warning is to use an octane booster additive if no gas of the rated octane for the engine is available. It even goes further to make a point to stop using that as soon as the right gas is available.
You are the other side of the coin of those who wish to use a gas of a higher octane than specified. The difference is that in this case there is no damage to the car, while the lower octane creates combustion at the wrong temperature and has other connotations, mainly through the GRS mechanism, affecting the plugs, engine and exhaust, the injection, and the electronic feed and response action.
Excellent example of penny wise, pound foolish.
A car would show appreciation for preventive maintenance by never leaving his owner stranded.
Defensive Driving is never having to say you're sorry: a true love story between man and machine.
