I'm really amazed by the number of people using regular. Of course if all are leased cars, then it would make sense. I also don't like to make the big oil companies richer or know that my hard earned money is going to the middle east...However, I knew when I purchased my car that in order to get the best performance I would have to use premium fuel... So be it, an extra few bucks at the pump... I would also think that a few more $$$ at each fill-up wouldn't be an issue for most current owners...Now for second and third owners thats a different story...

I also noticed that some have claimed to have used nothing but regular and haven't noticed any difference in performance...I suppose these opinions are based on seat of the pants feelings after occasionally running with a refill of premium mixed on top of the regular...then putting regular back on top of the previous mix...No wonder they haven't noticed any difference.

Now this tops it all IMO,
Why spend hundreds of $$$ on the "spring booster" a gadget that doesn't add one bit of performance and not use premium??? I guess I don't get it and I'm not going to make many friends by opening this can of worms... Sorry, but thats the way I see it...

By the way, let it be known that the spring booster is going to do wonders for your fuel economy. Also, your slow speed drivability (Traffic and parking) is going to be a wonderful experience. The only thing this gadget does is change the progressively ot the throttle plate opening, Its going to make it non linear (Big opening of the throttle plate for less travel of the gas pedal).

With what I'm saving by not jumping on the spring booster bandwagon is going to buy me a few tanks of premium and I can still use my right foot as it was intended to put the pedal to the metal...
