i was wondering...would i hurt the motor if i were to put fuel injector cleaner and octane booster with premium gas all at once into the car??

 

octane booster is like snake oil

 

No, octane booster does exactly what it says, boost your octane. If your car is not set up to make use of that extra octane, then that's another story. That being said, there's no point in using it in a stock S.

I can see no reason for harm mixing them, but it's irrelevant anyway since you don't need the octane booster

 

Paying 5 or 6 dollars to boost the octane 1-2 points max isnt worth it, though

 

Fuel system cleaner won't hurt either. I just put redline in and I'm getting 3mpg better gas mileage.

 

thanx for the info...just making sure cause i didnt wanna mess up my motor doin that

 

most of the off-the-shelf octane boosters you buy at AutoZone are pointless. If you want a REAL octane booster, you can use Xylene or Toulene. Both are paint thinners and will provide a significant increase in octane rating. However, you shouldn't use them too regularly as they will, over time, corrode lines and seals. The only ready-made and specifically marketed automotive octane booster I'm aware of is called Torco. And if you look at how it's made, it isn't too far off Xylene.

However, in a near-stock car, there's no need for it. You won't see ANY noticeable gain in performance, and the cost of materials will negate any amount you save in gas mileage.
