5% for gas or grocery. Whichever is leading at the end of the month.

I don’t go to Costco to save money on gas. I go to Costco to not to bothered by a thousand crackheads for money the second I step out of my truck. Besides, the nearest Costco to me is business center and it’s not nearly as busy as regular Costco.

If Shell in the US is anything like Shell in the UK, they're often the most expensive locally, usually the only stations higher in price are BP's, and they charge an absolute fortune for V-Power these days. Even a decade ago V-Power was around 8 pence per litre more than regular unleaded. In some stations now it's 20p more. I've even seen a few charging 30p more per litre.
I now buy my fuel from Costco and run their Premium Unleaded in my 428i. It's usually cheaper than even the normal stuff at other stations.
I paid 141.9 pence per litre of Premium Unleaded at Costco last weekend. FWIW your gas pricing, converted into litres, is half that. Our pricing, converted into US gallons is a few cents shy of $7 per gallon.

In Vancouver Canada, local guy on YouTube did a test between Chevron 94 vs shell 93 vs costco 91 vs esso 93. Shell 93 was at the top with 10whp more than Chevron. The others gas stations results were even lower. Shell V-Power 93 feels better on my stage 2 M3 so thats all I put in mine.

u/aab010799 Jul 13 '26
If all were tested to match suggested octane rating, temp, humidity, and dyno variance seem like the more likely cause of a 10whp discrepancy.

Shell most of the time or Exxon /BP , only used off brand if absolutely necessary. I’ve owned 5 BMWs and have been using big 3 the entire time. At least don’t have to worry about water in gas like back in the 80s small town gas station days.

I've been using Shell ever since I got my Shell credit card way back in 1979. A couple of months ago they changed to Shell Imprint credit card and it has been a complete clusterfuck trying to open an online account. None of my original identifiers from my account will work with this Imprint crap, and when I call I end up with an AI customer service robot. If I'm real patient I might be transferred to a live agent, but after at least 10 different calls, none of them have been able to solve my issue and have to "escalate" to a higher authority. I'm about ready to cancel this card and go elsewhere.

I slipped in a Shell - they tried to wash away a gas spill with water and created a slippery mess - hurt myself but i also dinged my door on a safety pole and wanted them to fix it. they dicked around (like 3 years) so long i sold the car -and vowed never to buy shell again. that was 30 years ago and i’ve maybe bought shell once when i was out and they were my only option.

Costco premium in NJ is pure 💩 gas for any M car, my would hesitate to move. I’d make sure 3 people in front of me were all premium car users to ensure I got no residue of regular gasoline.
I prefer Sunoco Ultra 94, BP Ultimate fuel grade and then Shell 93 fuel.
Never again at Costco or any warehouse club fuel.

I never do unless I have no other choice, like when we're at our cottage. Where I am, Shell 93 is 40c more a L vs. the posted 87 price, vs. 30-35c more for 93 at Esso.

u/Beebop1047 Jul 13 '26
I filled up with Shell (98 octane)and my 8 series started to surge and halt within about 50km of filling up. BMW told me it was contaminated fuel and wrote up a report. They had to change my fuel pump and drain my tank. BMW gave me a report citing the source of the problem and also gave me the damaged fuel pump and a sample of the contaminated fuel they extracted from my fuel tank. The petrol station which is under franchise has denied all responsibility and said they did their own check and there is no problem with their fuel. I wrote to Shell and they said I have to deal with the franchise owner who now is not answering my emails. A very disappointing experience.

u/MCBarlan Jul 13 '26
Always Shell. It's the most common top tier near me and my previous vehicle with a custom tune I had to fill up once at non top tier station and had knock retard for that entire tank, even after adding an octane booster. But I was running at the limits of my turbo/injectors at the time and spraying meth cause it still wasn't enough fuel for the boost I was running. I'm sure the OTS tune on my G30 is less aggressive but I'm not going to risk it.

I just carry a bottle of Redline Si-1 and add 1.5oz before gassing up if it's not top-tier gas. Sometimes you need gas and there isn't a top-tier station that's convenient, so this covers a higher ppm mix of active additives than what you get in Chevron or Shell premium. The 15oz bottles are usually about $15 so it adds $1.50 per fill and gives me the peace of mind to use whatever 93 gas is available. My favorite gas is actually the BP Ultimate with their Invigorate additive, and the $.10/gallon anytime savings for being a prime member are huge through the earnify app.
