Does anyone here run 93 octane? I've always put 87 in this car but i'm wondering if it would run better off 93. I know from the factory it's 87 but i've heard if you do some mods you might want to run the slower burning fuel?

i accually have ran 93 octane from when i first got my head built on my car around four years ago... ever since then the car i think runs like **** on the cheap stuff.. i have accedently put cheap stuff in it before and it runs like ass....

yeah i run 92 octane. ive been short on cash and ran 89, and that was garbage. i put a tank of sunoco 94 in it once, no good. 91 octane is recommended for my engine, 2.0 magnum. once had half a tank of 92 and filled up with 93. worked nicely. but 94 is simply too much. and 93 burns out quicker for some reason.

Well i filled up with 93. I'm pretty sure it's my imagination so i'm not going to say anything.

octain rating defines the anti knock characteristics of the fuel. Running higher octain than neededwill NOT help performance.

ya i tried this same thing and i thought i was getting better performance but it was just me making myself think i was getting better performance. I think ill just save the extra 7 or 8 bucks on the 87 or 86

I've heard that 93 is too rich for the 2.0 (non RT) Neons. The only time I ran 93 was when I had my AFX race pcm.
Especially with the gas prices, I say stick with the 87.

I used to run 89 in my Neon all the time (non-RT). I thought it was better than the 87, but after a couple years I switched back to the 87 and realized that not only did it seem a bit "peppier" at lower RPMS, but I get slightly better mileage with the 87 than with the 89.

Remember too that overall the 87 actually has more BTUs in it than 89, 91, 92-94, etc...

higher octane burns more and its aloys cleaner and add some performance.its good to run a high octane if you can afford it..
