Default Does it really matter?

I keep seeing people post about premuim gas prices and their SC'd cars. I have a SC'd car and I use plain'ol regular. Does it really matter with these engines? My engine code is 1

Just curious. I dont want to create more problems than I already have.


Thanks!!

oh ok I asked this same question because I am at high altitude and we can only purchase lower octane fuels.

As clearly indicated by the usermanual you can use 87 or higher, thats midgrade here but probably regular where you live and it will work but will kill your accellerations becuase the engine will knock more than normal, meaning the timing will retard causing issues, and if the timing does not pull back far enough due to less octane you could cause damage to your motor over time.

from what i've gatherd it all depends on who you ask... either side can (and will) defent their arguments.

the way i look at it is its only about $2.00 more per fillup for me to use premium then regular. if there IS some truth to it i'd be REALLY ticked off that i didn't use permium. so, i buy meijer gas. their premium is only about $0.15 more then regular...

I use 93 all the time, I won't use anything less. But I take it easy and go the speed limit (except at Bonneville meets). I drive 450 miles a week. I can afford the gas because I don't waste it. Don't get me wrong, there'* nothing wrong with having a little fun though.

Long-term damage can occur. Whether you feel it or not. The manufacturer clearly states that premium fuel is required for a reason.

Think of it this way. We can achieve 30mpg easily on 92 octane, while many cars struggle to get 20mpg on 87. That leaves us ahead of the game. Quite frankly, if you can't afford the fuel (of the proper octane) you should seriously consider getting a car that you can afford.

Long-term damage can turn into immediate destruction if your knock sensor ever fails. And the Series 1 only has ONE knock sensor. Not 2 like the Series 2 has.

cat converter alone raised my MPG at least 2 or 3mpg and probably another one once I put my new O2 sensor in. Fuel pump was also replaced at the same time, much better gas miliage, do this things. oh yeah and new plugs/wires and such just basic tuneup items including cleaning th TB parts.
