Not knowingly, I put 87 in my 5.7 l 2013 dodge charger( police package). Will this damage my engine?
No. The PCM/ECU will detect any increased KR (knock) and adjust the timing accordingly. You will not get the normal performance from the engine with 87 octane ... so I would refrain from any WOT acceleration. But normal driving should not be a problem. You can wait until you're half tank and fill with a higher octane; either the recommended 89 or even 91.Will this damage my engine?
