But then why does my CEL come on if I dont run 91?

TheUNZippee! · August 5th, 2007, 12:00 PM

Because something is wrong with your car.

MustangMatt96GT · August 5th, 2007, 12:04 PM

Well when its really hot out side and I dont run 91 I get a check engine light, Again at higher altitude you should run higer octane anyway so I think that that has something to do with it

TheUNZippee! · August 5th, 2007, 12:06 PM

Well altitude definitely affects things, so if teh 91 is making it stop pinging, I will allow this behavior to continue. For now. lol

MustangMatt96GT · August 5th, 2007, 12:14 PM

well I never heard a ping or anything, but I neveer really listend for one ethier! lol Once I have it tuned it will 91 or nothing!

god bless sunoco 94

matt you really need to listen for pinging. pinging usually occurs in higher gear and higher rpms. My car pings in 5th when I press the gas to WOT sometimes. and unless your car is pinging you dont need hi octane gas.

If you don't have a Cobra, tune, or some crazy specific reason that 91-94 is required, run 87. Save that money your spending and buy a tuner and have a good reason to run 93. I used to run 93 in my car before this one sometimes, and I realized it didn't do anything.

Everytime you fill up an entire gas tank your putting about $3 more into it than needed. Assuming you fill up once a week, that's about $156 dollars a year your burning up on premium. That could be a gear or something in the long run!

MustangMatt96GT · August 5th, 2007, 09:31 PM

I will fill up on 87 next time and see if my CEL trips and if I hear pinging!

TheUNZippee! · August 5th, 2007, 09:33 PM

pinging doesn't always occur at high rpm's. It can happen anywhere in the rpm range, and usually occurs when you first mash the throttle.

ujslost · August 5th, 2007, 09:46 PM

but its usually in the high gear when you hear it

TheUNZippee! · August 5th, 2007, 09:49 PM

No, not at all, actually. I've had many cars & worked on many cars ( I served 4 years of my apprenticeship to be a mechanic) over the years that ping as soon as you drive away in 1st gear. If the timing is off, or you have a higher performance car with the wrong octane, it will have detonation as soon as the engine is under load.
