>buy a 87min 93 recommended car>Run it on 87 for the first year of ownership >Decide to put 93 in it>It's a night and day difference Damn, they weren't kidding
They would not kid you Anon, the engine can run on shit fuel, but it will retard it's timing to the level of an engine made for shit fuel.
>>28746318Yeah, Ive noticed. It's so much smoother on 93More linear acceleration, less shaking Just a nicer experience all around
>>28746326for mine it seemed to really chug fuel when i put it on 91 RON and also seemed more sluggish. went back to the recommended 95 RON and felt peppier and didn't have to fill up as often
>>28746368I was honestly really surprised how much of a difference it made. Everyone online said the difference would be minor but the entire car just feels better with itThe noise especially
>>28746312Your engine is already ruined.This is what happened to all the mustangs with piston slap, started as knocking and progressed to piston slap.
why didn't you run it on 93 from the beginning
>>28746731He likes his engine ticking like a clock without it being a push rod v8
>>28746731Fuel door said 87, so I used 87Only in the manual did it say 93 recommended
