With the rising cost of gas, are my fellow 6 speeder using 89 octane with octane booster? haven't run this route yet, but doing the math, it's a hella lot cheaper............... what r u using for gas?????

 

don't do it i speak form experience! after a rebuild i now run a mix of shell 93 and sunoco gt plus 104 oct and dont boost over 1.3 bar here is a handy octane calculator

I was told your typical "octane booster" raises your octane something like .1 (89.1)

Dont do it

There are actual mixes u can run but it wont be cheaper by any means I would say

 

If the spread between mid (89) and premium (91-93) is only $0.15, and your tank is 16.9 gallons, the extra cost is $2.54 to fill up with premium. I have not seen any octane boosters that could give you 2-4+ for under $2.50.

 

You are driving an expensive/impractical sports car that gets so-so mileage and usually calls for a heavy foot. It costs more to fuel, repair, and drive. If you are really worried about 5 dollars per fill-up (which equated to 150 dollars a year for most drivers,) I recommend another daily driver.

 

I only use 93 in all my cars...

 

+1, always have and always will

 

I drive my Porsche for pleasure only, I drive a diesel pick-up for most of my driving, have you seen the diesel price per gallon lately, I don't mind paying 93 prices for pleasure driving.

 

Wouldn't try it.

 

You probably don't want to try this experiment on your car, start with something simple and cheap to fix if it does'nt work out, like a John Deer!

 

there are ways to boost octane (toluene), but make sure you know what you are doing. i'm not sure you will save money doing it properly. as said above most OTC boost additives give you very little for the money.

 

man...... gas is going to kick my butt.... given that an sc is going in........

 

the sc wont affect your mileage much as a DD... DD @wot with a sc on the other hand will.

 

great to hear red........ can't wait..... what r your other mods on your car red? i just love that 996 of yours.... if i had a coupe i would have done exactly what you did.... but since it's a cab, i went with the 02 face and sc.......

soon Evo SC stage 2 kit........

 

as others have said, those boosters don't raise octane level by much. they all say 103 octane or something outragous.

your engine should retard timing for lower octane at the expense of quicker wear on plugs and less performance. it shouldn't damage engine but i am not about to try it on a $10K engine !!!

if you commute a lot, look into public transportation, carpool, or a daily driver like a Honda that gets 30+ mpg easily. A beater 10-14 yr old car like an Integra costs only $3k to have which is just a bit more than a set of tires for your Porsche.
