Yepp, I am



But I'm still new and curious so a little poll might help.

Thanks fellas!

I run mid-grade (89 octane) in the summer and regular unleaded (87 octane) when it cools off. I can run regular without pinging from about October to May.

I run 87 octane all the time no problems yet

I run premium about 75% of the time.

If it's mid 90s and up I have to run premium (93 octane)
If it's 80 up to the mid 90s I can run the mid-grade (89 octane)
and cooler than 78-80 I can run the regular (87 octane)
Here in Georgia, most of the regular riding season is above the mid 90s, but it does seem to run it's best (power wise that is) on the 87 octane.

Here in the hot, humid South, I find I have to run 93 octane. Danged thing simply won't run 'right' with anything less. I tried 89, but it just didn't work. Don't dare to try 87.

Well..I run premium all the time, but after reading a couple of the post on here, I might have to start watching some temps and experimenting with different grades to see how the "Ping" "No-Ping" goes... I know my Nad much prefers the cooler weather!!!

Premium all the time. I don't want to take any chances with pinging.

From prior threads, some Nomads have a tendency to ping more than others. Mine doesn't ping.
I run 85 octane, the low grade here. I live in Denver, and ride in Utah and Colorado, both high elevations with no pinging.

Since my most recent round of modifications - Cobra FI2000R and Caddmann Kit, pinging is nearly non-existant. Maybe I just can't hear it over the roar of the intake, I'm not sure. I have been using 89 octane. On road trips with lots of high-speed riding, I'd use 91 to try and eliminate pinging during high-speed roll-ons. I'm going to keep 89 in it for awhile.

Interesting, seems like everyone has some preference, but the most important fact I am getting out of this survey is that mid-grade won't HARM the engine unless you start hearing pinging. Appreciate it!!!

I voted for the premium but I can and do run some mid grade in cooler weather. Or do a partial fill up with 89 when I already have 93 in the tank.

[waterman]

I run 85 octane most of the time. Do fill up with 87 when it gets hots here.

Premium all the time...no pinging or other issues. Have never tried a different grade so it might be fine on Mid or Reg. Mine is a 1500fi.
