Question Is Premium Gas Needed After Steeda Timing Adjuster Install.

I'm about to install my Steeda Timing Adjuster @ 14 degrees on my 2001 GT, 4.6L-2 valve engine. Do I need to burn the high-octane "Good Stuff" or will regular gas work just as well? If I don't here a "ping," I think regular gas will be just fine. Does anyone have any experience with this?

You should start with 93 but you can try 89 down the road to test it out. I run 89 and get no detonation (audible or visual) at all with 15* of timing.

Every engine is a little different. If you can get by with 89 octane at 14 degrees advance and get NO detonation, it might be fine until the summer months when it gets hot outside. Once the ambient air temperature goes up, so does your intake air charge temperature. The difference between 40 degrees outside and 90 degrees can be enough to require 91+ octane at 14 degrees advance.

That timing adjustor is adjustable for a reason! You might be able to get a few more RWHP out of your engine my bumping advance to 15 or 15.5 degrees and running super-premium fuel (93+ octane). You did buy your adjustor for maximizing performance, right? That, and the web site and instructions were pretty clear in telling you that premium fuel (and the $1.90/gallon pricetag) were a necessity.

Thanks everyone,
I didn't know for sure if premium was needed. I must have missed the part on the Steeda web site. I will fill my tank with 92 octane and then install the Timing Adjuster. I will experiment between 14 & 15 degrees of advance. If gas goes to $3.50 a gallon, I can always go back to regular and 10 degrees factory setting. But if you enjoy driving a Mustang GT much as I do, you might as well pay a little more for the added performance.
Thanks Again!
