Brand of gasoline

[Bavarian Motorist]

I have usually always gone for the cheapest gas I could find.


I run 93 octane and I have an ECU tune that was tuned to optimize performance using that octane.




I am not the type to fall for marketing hype (though I suppose we all do to an extent) but I hear all the time how Shell gas is great and Ferrari racing teams use it. Even at the pumps, it says, "quality fuels." Then, of course, it gives 93 octane gas a special name called "V-power".


On top of all this, it even costs more on average.



Is Shell gas better for performance? Is any brand of gas better for performance or are they more or less all the same?





Thanks!

have a look through this thread regarding gas and Top Tier Gasoline

i had a friend, who's way into cars, tell me that all gas is pretty much the same. the differences came in where each brand adds there own special mix. he told me that he knew someone that worked for one of the refineries like shell or mobil. he went on to say there were a group of different companies all in the same location like shell, mobil, exxon and they frequently bought/sold gas from each other.

not sure i'd buy from a no name brand. i use this site as my gauge and just find the cheapest high octane on my trips: http://www.gasbuddy.com/

I have mixed thoughts on this. Being that I work in marketing, I'm well aware of how companies to market to consumers, so I take anything that's marketed to me with a grain of salt.

The real differences of street motor fuels concerns their blending, and particularly, their additive package. There are better and worse street fuels.

I do know that many of the Top Tier suppliers trade fuel frequently depending upon demand and individual supply. Locally here we have a large car wash chain, that I know one of the owners, as well as a few managers at, who sells their own fuel, under their brand. Turns out they get it from a Top Tier supplier, so I am able to take advantage of lower priced fuel that is still Top Tier. That said, I am weary of buying fuel from no name locations.

I still run some BG 44K through my cars every 10k or so to help keep things clean.

I use only Chevron. Great gas.

I used to use off-brands and had to use fuel cleaner on a regular basis.

I would stick to a Tier 1 gas if I were you.

Thanks guys.



So Sunoco-Canada is top tier but not Sunoco in the U.S.?




Unfortunately for us Yankees, NONE OF THOSE gas stations exist here aside from Shell, but there is a list of companies on there that may provide gas to other big chains so I am going to google them and see who they're associated with.





EDIT: On the Chevron site, it says they own Texaco also. So Texaco would be a top tier gas, eh?

A few years ago, I only used Valero gas. Then Shell put on that commercial saying you get better mileage out of it, so on a road trip out to Phoenix, I tested it.

I started with a tank of Valero. Then I filled up with Shell.

I got about 30 miles more out of a tank of Shell than Valero. Then Shell sent me a gas credit card, so I've used Shell ever since.

i used shell and my 986 S had less kick...I always use Mobil 93 octane.
porsche recommends Mobil.
