You beat me to it, but ya. The car runs worse with higher octane in my experience. I get crap from people sometimes, but I don't care as they really don't know what they are talking about. I use Shell for the most part. Chevron is better, but the cesspool of the midwest fails to get it.squared away said:And I'm not poor for putting in 87, I'm following directions.

Yeah, exactly! Being poor has nothing to do with it.squared away said:...I fail to see any benefit from adding higher octane fuel.
And I'm not poor for putting in 87, I'm following directions...
Waste of money....A waste of money is using 87 'cause you probably haven't taken the time and used the 91 for several tank fulls and you dont know the difference between your car running better and smoother with 91compared to it running crappy. If you havent used the 91 or even 89 for a couple of tanks (more then a week) and only use the 87, you wont know the difference. So spending an extra $0.20 on gas really does make a difference.rsowell28 said:Yeah, exactly! Being poor has nothing to do with it.
If my RS was supposed to run on 91, then that's what I would use. I don't care about the cost. My previous car was a 1997 Prelude w/ VTEC. The manual called for 91 octane so that's what I used. My RS is designed to run on 87 octane so that's what I use. I don't even look at the gas prices. I just swipe my gas card and fill the car with the proper octane fuel.
Unless your RS is turbocharged or supercharged or you are running agressive tuning like advanced timing or something, using anything higher than 87 octane is a waste of money.
Sorry dude, Id didnt mean to confuse you. I dont know what you should use when running a ProECM, but I do know that using the higher octane does make your car run better. NOT saying this for everyone, but it looks like the majority say the prefer 89 or above.rsowell28 said:I thought that if you were running the ProECM, that you had to use 91 octane or higher because it advances the timing. I don't have one though so I don't really know. Could somebody who has one please clue me in? :burnout:
I did try 91. I ran 91 for the first month that I had my RS. Then I realized that 87 would probably work better so I switched to that. On 87 my car runs the same as it does on 91 except it gets better mileage and 87 is cheaper. My car is n/a so I don't need a high octane fuel and the car is designed for 87. 91 will work fine but it's more expensive and the mileage suffers.CWC.02 said:Waste of money....A waste of money is using 87 'cause you probably haven't taken the time and used the 91 for several tank fulls and you dont know the difference between your car running better and smoother with 91compared to it running crappy.

UNLESS: You have compared the Octanes and the 87 does make your car run better...but i doubt it.
You dont skimp and use cheap parts when it comes to other important parts of your car do you, then why skimp on gas?
Do you have a ProECM? Maybe that's why your car runs better with 91.CWC.02 said:Sorry dude, Id didnt mean to confuse you.
