yeah---thats what I am saying..does anyone here know the real deal on these octane boosters.?? a couple of friends say its not worth it..they just add AV Gas instead because gains with one bottle of boost is useless......but it seems other people use it all the time..???

in NJ we have 87, 89, and 93. sunoco USED to have ultra 94 up until like last month wtf? premium used to be 93, 94 ultra wasn't advertised on the sign but it was available at the pump for extra. now, on the sign they have regular 87, plus 89, and ULTRA 93 (94 is gone...) advertised on the sign but no premium is advertised. however, premium 91 (yea, premium is no longer 93, it's 91 now?) is available at the pump for cheaper so i just use 91. sunoco now carries 87, 89, 91, 93. sunoco is all i buy unless they're out of gas and i HAVE to go somewhere else.
this is wacky. 5 years ago, regular was 89, plus was 91 and premium was 93 EVERYWHERE in NJ. we get lower octanes now and the price doesn't go down. why? no one notices the octane!

I use mostly 94 in my car now. If I run 91 in warmer weather I get pinging in the low rpms (1000-2000) at part throttle (this is mainly due to the fact that I had my timing bumped up 3 degrees in the lower rpms in order to get better throttle response)
The big problem with running 94 is that up here the only choice for 94 does contain 10% ethanol, and I get 10% less MPG using this stuff (18 MPG average compared to 20)

listen to me...
it is really dumb NOT to run 91 octane in your car. when your engine is new, it adapts based on the gasoline run in it. you should ALWAYS start with the MINIMUM octane the manual requires. why? like i said, your engine is broken in on that octane. when your engine is broken in on 91 octane and later in its life it begins to ping, simply up it to 93. ping gone. when your engine is broken in and used to 93, what do you do when it starts to ping? you have to go out and buy octane booster for the rest of its life. it won't perform ANY better on 93 than 91, the "increased gas mileage" is a total myth - a TOTAL placebo effect - and does not justify the increase in gasoline cost. you should always make your engine used to running the bare minimum so if a problem ever does occur you can fix it with higher octane. when you give it the best, when the best doesn't become enough anymore you have nowhere to go. all you 93 runners out there have done your engine more harm than you know.

My car has never seen anything less than 93 octane. The only way my car will see less, is if they stop offering 93. 
My friends think I'm crazy spending the extra money on "just a car", but cars are my life essentially, so I kind of want to live in that metaphorical sense

CATS !!! NOT LIKELY... I wouldn't run them if you paid me...
