From the factory a 2005 4.0L is designed to run on 87, anything higher is just a waste of money. I've never run anything but low test in my Jeep, not once did has it pinged.[/QUOTE]
thats all I ever run in my jeep is 87. But if i buy any cheap gas no namer in town she pings like crazy. So i have to run 87 from a station like exxon or shell or bp then it runs great.......so i guess not all 87s are the samesomething in the cheap gas thats making the jeep ping

Back in the day...
In California, premium leaded fuel was 100 octane. There was a distinct difference in brands then. We always used Shell 100 or Chevron, but Shell was best. Texaco, Mobil, etc were not so good, got more pinging from their gas.
Nowadays, around here we can get 91 octane only and I run whoever is cheapest, but on my last road trip I used Shell and Chevron mostly. The couple of times I used off brand gas, like at a convenience store, my bike ran just fine with the same gas mileage. I think EFI compensates for any variation.
My car's manual says 87 octane, but here we have 85, and it runs just fine on it too. I heard somewhere that lower octane fuels work fine at higher altitudes. We're at 3,000 feet here.

I run 93 all the time from Chevron or Shell. I tend to stay away from BP as they watered down their gas pretty hefty around here last year and it ****ed up my bike twice.

While the topic of gas/octane/additives is on the table, I'll throw out a fun fact many don't know. Those "octane boosters" that advertise raising your octane by "3 points" or an off road only formula that raises your octane rating by "7 points" is actullay reffering to .3 or .7 octane. So your 87 would become 87.3 or 87.7 etc. Many people assume that these "points" are a full single octane rating. Far from.

Branded gas only for me. Used to deliver gasoline and have seen the variances in brands that will go into unbranded stations. I agree with the post of the quality of gas when it leaves the refinery, it's what happens afterwards at the tank farms, transportation vessels and conditions of handling of the product that makes the differences.

I only run "top tier" 93 octane gas and by order of preference it's:
1 - Shell
2 - Mobil
3 - Chevron
4 - Sunoco
5 - BP
6 - Hess
Unfortunately, here in Florida it's required they stick up to 10% ethanol in the gas which really stinks big time.
