Who's gas is better Mobil or Sunoco, anyone know???

Sunoco has STOPPED the sale of this particular octane Ultra 94 brand. So its either Sunoco 93 octane or Mobil's 93 super unleaded. Is one better than the other or are they the same?
TIA.

Stay with Sunoco. While living on the East Coast, i've had problems with Mobil fuel since my first BMW, an E34 535i. My 740s didn't like it, and my M5 was even worse. Citgo is bad for my V8s as well. Sunoco is good fuel, but the best i've found is Amoco (midwest) and Chevron (west). When travelling cross country (pretty often), these are the fuel stations I actually wait and time my stops for.

To answer your question, stay with Sunoco.
Or, find a Texaco that uses Techron in their blend. I've got one in my area and I find my car runs the best on it. Unfortunatley, they're always a bit more expensive than the other stations. Sunoco is good, as is BP/Amoco. Shell makes my car stink more than any other brand. I'll never buy Exxon or Mobil, possibly more personal than anything.

"Better" is a very ambiguous question. Are you asking which has higher octane or better detergents or less ethanol or what?

Many fuel characteristics are more a function of your locale. Blends vary by region due to merger acquisitions, urban and state emission requirements and farm belt alcohol influences.

For example, BP in Pennsylvania now sells top quality Amoco Gold Premium 93, but the BP you see in Califirnia is the old pre-Amoco crap they sold in PA 15 years ago.

Lscman,

I live in North Carolina - any idea what brand down here is best for the M5 or where I could find that info?

I had been using Shell 93 octane with the "V" power additive for a long time but recently switched to BP Amoco Ultimate and the car "seems" to run a little better.

I always read your very informative posts and replies and would welcome any advice for us regarding good premium gas here in NC.

Thanks

I'd stick with the Amoco, if you can get it. The top tier gas list is probably fairly reliable, but their exclusion of BP-Amoco Ulimate can only be described as suspicious. It was recognized as the #1 choice since the 1960's & I never read anything suggesting it's quality has been compromised in recent years. Shell had serious sulphur compliance issues affecting Nikasil and yet they are on the list. I have to wonder if you pay somebody to get on this list.

Wouldn't suprise me. Just read a book on natuaal cures and remedies, where a former 3-year term head of the FDA stated flat out - that the FDA approval process was slated 100% toward corporate control, keeping out the little guys, making huge cash and had almost zero to to with protecting anyone's health.

So a few suspicious names on a gasoline (read: Oil corporations) list wouldn't suprise me.

Like today's news item of Exxon-Mobil funding an interest group that is responsible for alerting the IRS of money-laundering activities in Green Peace. After an IRS investigation, Green Peace came up clean. Isn't that sweet? When you've got a ton of money to throw around, no doubt some of it ends up in some interesting places...

IMO Mobil sucks, makes my car run like $hit! I use Sunoco or Shell. Since I switched from Mobil my overall gas consumption went up from 15.1 to 16. Nothing earth shattering but makes my car run like a dream. I also noticed when running Mobil, I would occasionally get a random "SES" and the code would be for "cylinder mis-fires". MY local $tealer suggested changing fuel. It worked! No "SES" since I stopped using Mobil.

My favorite was AMOCO gold 93, but all the amoco stations up and left CT???

Untimately, it comes down to personal preference, trial and error, what makes my car run well
