i can get 110 octane around my area for $3.99 but filling my tank at $3.99 would break the bank...could i use a few gallons of the 110 race gas and the rest 93 octane? would this cause any problems? would i be better off just getting a good octane booster?

 

Is there a reason you want race gas? If you only have i/h/e you shouldn't need 110 octane.

 

it would be for the WRX

 

wrx doesnt need 110 octance...its not 800hp or anything. unless you got a drag car just use 93.

 

putting gas with higher octane than you need will not give you any power or make the car run better......in fact higher octane gasses will not burn completely and the exhaust will be much dirtier........i forget who did the test but a 4 cyl accord was filled, run and dynoed with different octane gas and it actually lost power with the higher octane.....granted that was an accord and this is for the scooby but you should stick with the 93 if it is stock.......under higher boost conditions higher octane will be needed to control detonation

 

i do plan on upping the boost a bit later on, ishould be pretty set tho at 93 for what id be doing...i would ike to see how it would run on 110 tho

 

it wont run any different.....

 

110 way to much. dude that car was built for the street not track. wtf you need 110 octane for. waste your money if you want.

 

Can you actually run 110 OCtane with a stock fuel system? Aren't you worried about trashing the seals and O rings?

 

It wouldnt run any different. In fact it might run worse, as that high octane may burn incompletely under stock boost.

 

you should be thankful you can get 93!
