Highway...........Who's selling branded AMOCO? I thought they were absorbed by BP (British Petroleum) a couple of years ago. ?????????? If Shell ate the fuel unit in an Explorer, how come the other 1.765 quadrillion Explorers don't have the same problem???? Seems to me that Shell is (even if it IS a Netherlands company) one of the last of the "American" brands. QUICK.......! Name all the American oil companies from ......1955. < NEW THREAD !!!!
There's plenty of Amoco branded stores here in NC.
As to the Explorer, it would spark knock/ping on just about everything except Shell 93 octane. That's all we used in it for several years until we sold it. Shell is probably fine to use now though, as that sulfer problem was corrected some time ago.

Re: Top Tier Gas
I have never had an allegiance to any brand. I burn what ever is convenient and the best price. Never had any fuel related problems. Then again, I am a bit of a skeptic when it comes to the "best" gas or oil. Just my $0.02 FWIW.
Shell gasoline ruined the gas gauge (or sending unit) in our Explorer some years ago. It's about the only top tier in my area, but I'm not likely to use it anymore. I mostly use Amoco now, but it's not on the list. I'll have to check around and see what's available.

Re: Top Tier Gas
I too switched to Shell gas, and my 91 was quick and powerful. If the world's top auto companies such as BMW or Toyota recommend it, there's got to be a reason. Put in some Sunoco 94 in a bind, now my engine runs like garbage, and nobody knows why.
As as added note, I posted a thread in the Forum regarding my recent NJ-FL-NJ round trip in the Deville - on the trip, I put in Shell, Chevron and Texaco gas at the various stops up and down I-95 and in Port St Lucie - and the mileage on my return trip was a rather suprising 28 MPG - this at 70-75 and full on AC..
We have a lot of Sunoco stations around here, and thats where we both tend to fill up, as a local station with a half-way decent price is on both of our commutes. Its nice fresh gas usually, since the refinery is about 20 minutes up the road.
If we had more options for gas, I'd probably try one of the T/T brands, just to see if there was any mileage or driveablity changes. As for our normal day to day stuff, I haven't had any problems with Sunoco regular, and have used it all my life.
Question: Is the top tier fuels ALL octane/grades? Or Premium fuel only? It isn'tlisted. And FWIH the "branded" stations that are not corp stations do NOT have to run the branded fuel in all grades, only the Premium grade.
True? False? When I see a top tier station that has brand x on it and the same fuel tanker serves it and the el cheapo station 2 doors down, how on earth do you know what you are getting?
