what do u guys run? i've been running 93 octane but it is so damn expensive (like $1.86/gallon!). i put in regular (isn't it like 87 octane) once and my car was noticeably slower (at least i think it was), so i haven't put it in since. i know the nissan recommends 93 and i know the science behind the higher octane gas and how it is better in some engines. what do u guys run?

 

run whatever your ECU is programed for. i always fill up with 87. if you use higher or lower octane without proper engine management all you will do is throw off your timing and screw yourself over.

 

i use 93 .... alot of people use 93... i hear you get better performance... very slightfull but u do hear about it... here in ny gas is about 1.69 for 93 at good locations... what company do u guys suggest ? i use hess and sunoco... is that good ?

 

The 240 gets 93 and I stick to Amoco and the Shell next to my job. I stick with the big names when I travel. The name doesn't always mean you are getting the best quality. Remember these stations are franchises so they can do whatever they want when not being checked upon.

 

so u suggest amaco ? i hear mobil has good gas too... i just want something suffuicient that will be good on the car and last long... some gas is just stupid and drains mad quick

 

There is really not that much of a difference in performance between 93 and 87. Not significant enough for you to notice at least. I ran premium for a while but decided it wasnt really worth the extra money. The 240 really runs fine on regular. I usually try to stay away from the lesser known stations, like Getty, Gulf, Coastal, Wawa(yes, there's a wawa gas station around here), Gasteria, and the like.
