BMW recommends Shell gas, but it's more expensive than other brands

[David70]

For all the people thinking Shell gasoline makes their car run better on one tank, they get better mpg on a tank, or whatever, I can't even see a way for this to be possible. Base gasoline is the same as Walmart, Shell might have more detergents in it but past that I think it is in your head.

Different or more detergents won't suddenly raise performance and/or mpg and even if it did it wouldn't suddenly drop when you went back to some other gas.

BMW will change it's recomendation as soon as the next fuel company writes them a bigger check. Just like their oil and oil change recomendations. I wouldn't get too caught up in it.

I sometimes get premium gas at the local Sam's Club because it's the cheapest.($3.149 last week) For some weird reason, there are always a lot of Mercedes and Audi waiting in line. I figured that if it was good enough for them, it was probably good enough for my BMWs?

Back when BP was still Top Tier, my local BP station was forcibly closed for over a month by the state's department of weights and measures(or something like that) due to bad pumps and contaminated underground gas storage tank. Needless to say, I never went back again.
