I use 89. Saying that anything but 87 will ruin the motor sounds like b.s. to me. I used to run Exxon 93 in my riding mower... lol

i doubt it will ruin it, but you're wasting your money. the higher octane is only beneficial for higher compression motors. if you had a supercharger it would make a difference, but on a stock motor, you're just wasting money. if you're not pinging or knocking on hard accelerations, you're not getting any precombustion, so no need for higher octane gas.

I agree with Shortbus, if the manual says to use 87, then that's all you need, and using 89 or 93 will be a waste of money for your stock h3.

yeah thats what i figure. the stang is rated for 87 but with the nitrous i have to run 93 to prevent detonation. i wasn't sure with these 5 cylinder engines though.

I wondered where those 12's came from with the Stang bro. The juice! I have NOS on my 350z. run's a 12.6 at 112. But I run Sunoco 100 octane and use NGK cold Iridium plugs when running the juice.

I agree, regular gas is all we need. Thank god for that!

yeah i have a NX wet kit with the 100 shot in it. I'm upping it to 125 and I only run 93 in it. I too run the NGK colder spark plugs (they're recommended). check out my car domain and I have some other mods you can check out. whats your 60'? its fun to have something that runs that quick, huh?

I have a NOS wet kit 100 shot, NX RPM computer and Nitrex filtered solenoids with a custom side purge. Autometer CF NOS pressure and A/F gauges. My best 60' is 1.798 Yeah 12's are fun, some slicks and 11's would be even better!

yeah with what your trapping at and your 60' i figure you would be a bit faster in the 1/4. yeah i have autometer gauges running up the a-pillar and all the purge,bottle warmer and custom switches that fit right in my cup holder. if you want to see i have it all in the car domain thats listed in my sig.

I tried 87 in my last tank. Didn't really notice a difference other than maybe slightly less MPG. I've just always used 93, but in my last 2 daily drivers I've used 89 (a Chrysler Concorde LXi 3.5L and now the H3)

Not to discredit any of your thinking about what you believe is the best octane level for this H3 engine...Based on the R+M/2 octane rating equation for all USA and NA engines.

But in today's modern gasoline engines as well as this H3's Low compression engine, the onboard engine management computer (ECU) monitors the engine for any predetonation and adjusts the timing accordingly..The baseline setting is optimally set for 87 Octane...If you were to use the slower burning 92+ octane you are pissing away your money needlessly and also carboning up your engine, so otherwise you're just fooling yourself...The more you use this higher octane fuel the more the carbon build up will become and eventually you will NEED to burn it as the compression ratio will have increased and the ECU adjustment will no long be able to control predetonation as it will be outside it's window of tolerance for control...The Best thing is to use 87 octane and no lower, unless you hear any pinging at higher altitudes under load, then step up to 89 octane...89 octane is produced by blending at the pumps the only two sources from the two underground storage tanks of the Station, the 87 and the 92+.

Hope this sheds some light on this age old confusion
