So, would modifications such as a better exhaust, cut airbox or better filter apply to this since they are allowing more air into the engine? Also, could a colder heat range spark plug, that has a lesser gap, fix a misfire instead of having to use higher octane fuel to deal with the higher compression?
Might be a dumb question, but what all does it do for you?
Okay that clears a lot of things up for me. Thank you guys. And that 9 dollars a gallon is pretty intense! New York has it bad haha. Down here in Eastern NC it's only around 4 dollars.
Oh ok haha. That makes a bit more sense.thats the price of 110 octane, i shoulda mentioned that lol. regular is about 4.07/gal
the short answer.. there are none. high octane gas actually burns less furiously than lower octane. it burns cleaner though. the only reason you need higher octane (and i mean only reason) is if your advance your timing or increase compression. the higher octane rating keeps the fuel from detonating early (i.e. predetonation) it is harder to ignite this keeps the engines combustion cycle in order. to high of an octane rating and you are robbing power. to low and you may be doin damage because the gas is igniting before the piston is at tdc. having an exhaust or even getting port work doesnt warrant higher octane. milling the head to increase compression or getting a stroker crank or advancing the timing all increase the compression and thus require the higher octane.
yea, i was gonna say that, just to lazy to type...
Just put some premium race gas in her slap a few number stickers and go to the mower races and haull ass or mow some grass WHHHHHOOOOOOOO!!!!!!!!!!!!!!!!!!
So should you just run regular in a blaster or be safe with the premium (next octane grade up right?) What do you guys run?
