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!!

increased KR,poor performance and poor fuel economy

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.

Oh :( I better get a PT job for my fuel fund eh?

Ive even seen the wording on my gas cap "premuim fuel only" but with prices over $3 im not ready to take that plunge into my pocket I cant afford to.

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.

Buy a NA Bonnie

it still cost me 50 bucks to fill her today
50 ******* bucks........
and the guy says have a nice weekend. ya right I'll see you on sunday.

My L-67 uses every drop of "Premuim" I put in it.....why is that??? Is something wrong??? Do I have a problem with my Throttle Body? or is it my Fuel Pump?? or is it my (no it couldn't be) (I refuse to believe it) could it really be my FOOT !!

ken

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.
