WORKS MIRACLES!!!!!!!!! i put it in yesterday when i filled up cuz i wasnt feeling too happy with gas milage and performance and lemme tell you something that stuff is really really good. for $5 i felt like i got a new engine.

its a silver bottle called:

prestone fuel system cleaner with 0-60 boost octane

 

i read before that we shouldn't use octane boosters in our car? What kind of performance did you get? faster accelerations? better gas mielage?

 

I got a bridge i'll sell ya...

 

better accerlation gas milage was slightyl better

 

I did a little research on the Neon srtforum and was surprised at the upgrades offered by Mopar!

Anyway, the hot topic is the performance of an octane booster called NOS Racing Formula. It has turned some skeptics into believers, and owners are reporting that they are able to run stage 2 or 3 in high octane mode (HOM) with the addition of the NOS racing formula.

The only concern is if long term use or abuse may harm the o2 sensor or catalytic converter? Plus, these cars are running at a high turbo boost, while ours are not.

May be worth a try?
