Costco gas

Anyone know who supplies costco with their gas? Is it a regional thing?

 

Don't know, but the quality is like Arco's gas. Runs out fast.

 

I think that Costco's gas is regional like everyone else. I have always heard that each brand of gas, i.e. Exxon, Shell, etc. all start out with the same gas and then add their own additives or detergents just before delivery. If you think about it, there is no way each gasoline company could have there own refinery in each market that they serve.

 

I buy it. Though I don't think it runs out any faster than any of the other brands, i.e. shell, 76, chevron. I have been getting around 300 miles out of my tank, no matter where I buy the gas. Just my $.02

 

Like 28guage said, all gas is same. Only difference is additives. A company will put in x number of gallons at one end of a pipeline and take x number out at the other end of the pipeline.

 

I use Costco, Arco or whatever I can get. Doesn't seem to change my 13.4 MPG.

BTW, register your Mobil SpeedPass and get $.15 off each gallon up to 100 for the next month

Register your Ralphs Club card with Shell and get $.10 off per gallon indefinitely.

Every penny counts these days.

Lately both Arco and Costco gas (here in San Diego County) has been giving my Tacoma terrible mileage... I believe they are using the same source of cheap, high ethynol blended gasoline. When I was doing traditional 16 mpg driving... I was geting 14-15 mpg! This has been the past month... No more!

 

There are 30 refineries in this country and a new one hasn't been built in over 30 years. Yeah, all coming from the same place, really. The additives do seem to make a difference from brand to brand. I "seem" to get better gas mileage when using Shell vs Costco or the no name brand (Murphy's) out in front of my job. Shell, probably not by coincidence, is the only Top Tier gas station around here.

 

I've been using Costco gas for the last two years and =have averaged 18.5-19.5 mpg, fwiw

 

gas is gas, man

 

I disagree. There is a noticeable difference in 10% ethanol (costco gas and many other stations) and standard gas.

 

The next time you fill up at Costco, check the pump for a ethanol content sticker. They might have switched from E-10 to E-15. The higher the ethanol content, the more the MPG's will suffer.

 

Gas is gas...The MPG difference is all in your head, it's your butt dyno lying to you. Butt dyno's are dirty rotten liars.

The only thing that affects your mpg is the ethanol content and your driving style.

Around here everything is 10% Ethanol. I usually buy my gas at Kroger (Grocery store) It's .03 cheaper with my Kroger plus card and there is a Kroger on my way to work by my house and another right by my office. If it's a weekend I usually fill up at QuickTrip or Racetrac.

 

I've been topping off with Costco gas lately with the rising cost of fuel. Just not worth it to pay 10-20 cents more per gallon. I'll be switching back to Shell as soon as gas prices go down a bit more.

I have a friend of mine that is retired from Chevron Oil Refinery in Pascagoula, Ms. and he says three are only 3 different gases in our area.

Amoco (BP) refines just their own oil which is bought all over the world.

Murphy Oil (Sam's & Wal-Mart) which is pumped out of the ground in Ok. and Ak.

Cheveron, Exxon, Texaco, Shell and etc. are refined as the same gas in the same refinery with different additives added in the last stage right before it is loaded in the tanker trucks. All of their oil is bought from Opec.

I used to prefer Amoco fuel quality but, after finding out that Murphy Oil is not sending money to Opec Oil Monopoly, I have been trying to use Murphy Oil exclusively.

Also, Ethanol is the worst thing for fuel and fuel economy. When I order fuel for my business I order 100% gas with no Ethanol. There are a couple independent gas stations that sale 100% gas but, they are usually very hard to find.

 

All CA gas stations have 10% ethanol. You can check here if there is an ethanol free station near you. http://pure-gas.org/

I use Costco gas all the time

 

In CA all gas has ethanol... therefore... gas is gas, man

 

You are freakin out...MAN
