Hi,

With the recent upgrade from all leaded fuel to a lower octane rating leaded fuel is it save to just use a higher rated unleaded fuel instead of the regular? I have a '69 280sl which is mechanically fuel injected.
Ever since we've lost the leaded fuel, I've had some backfiring problems under acceleration.

Thanks,

Kevin
