Oh yeah, the DSC must be off , especially when autoxing....but for everyday street driving I keep it on....but you may also find that your tires are spinning more because, aside from wet conditions, the performance of the tire is affected by temperature.

 

i had the same issue, but my car is a 07 m3 s touring. i had a rental car last weekend and it had good acceleration (it was a 2.0L) and my car with poor acceleration (2.3L). i do baby my car, but i GAS it on occasions. so i just need to rev it up higher to break it into that speed range? pls let me know thanks!

 

i totally understand what your talking about, but i just feel like it cant be anything else but the way the car is driven. if it feels sluggish just push the gas a little bit more and you'll get your fix of need for speed[8D].

 

i actually noticed that my 2007 mazda3 s touring seems a bit slower after i switched from 89 octane gas to 87. idk maybe its just in my head but i definitly am percieving a difference

 

well the ms3 shouldnt take any less than 91. i personally put 93 at all times.

 

hmm, i started my car with 91 octane fuel i got about 340 a tank. but now when i downgraded the fuel, seems like it gets lower mpg. anyone notice this or it's just me?

 

When running 89 octane gas my MS3 would surge. Definitely noticed a change for the worse in performance. I usedLucas Injector Cleaner and Octane Booster for a few tanks of gas to help purge the system.

I'd recommend that you only use 93 or 94 octane fuel from a top tier station...Sunoco, Shell, etc. I personally prefer the Sunoco 94!

My car loves it!

 

94??? ive never seen or heard of it. is it only in rural or small populated areas? im asking because diesel engine cars cannot be registered in ny because of the emmissions. mayb its the same thign with the 94. does anyone know?

 

94 octane is available in Ohio. I was through NY a few weeks ago on my way to Mosport for the ALMS race and noticed that Sunoco only had 93 octane. It must be a state regulated thing? All I know is that my car does not like low octane fuel or gas from a second tier station.

Made that mistake once and will never do it again!

 

hmmm have any of you ever thought about putting airplane fuel. at my work i sell 100 Low Lead Fuel and its pretty crazy. but then i realized that the car would probably blow up haha
