Thanks for the input guys.

I've been using the 100 octane fuel from assorted East valley locations, but recently sold my car to my brother in law which lives in Gilbert. I figured there must be some pump 100 around there. Every engine is different I'm sure, but the range of proper octane for this engine seems to be in the 97 to 100 area. At the time of engine purchase Roush suggested 95 octane minimum. I have found leaded 110 octane in this particular engine produces less power than 100 octane. Newer Roush 427Rs don't seem to be set up quite as hot at this one.

Here's a recap on a few stations around Scottsdale.

Cave Creek and Union Hills Valero, 100 octane unleaded from pump

56th street and Bell 76 station, 100 octane unleaded from pump and higher octane in back

96th Street and Bell Valero Scottsdale Auto Salon, 100 oct. unleaded from pump and higher octane in back

Pavilions at Indian Bend and 101 76 station, 100 unleaded in barrel and 110 leaded in barrel.

Speedway(used car parts) 2300 West Broadway Road, Phoenix, Arizona 85041. They have about everything.

Many ATV shops sell higher octane fuel in 5 gallon jugs too.
