Why is Costco gas so much cheaper
Re: Why is Costco gas so much cheaper
Regular at Costco today was $2.48. Most other stations in the area $2.75.
It is by the goodness of God that in our country we have those three unspeakably precious things: freedom of speech, freedom of conscience, and the prudence never to practice either of them. --M. Twain

Spread is greater when oil is dropping because they
buy daily
Spread is negligible when oil is rising.

I've heard that as well. Some mechanics I've spoken with think that the additives make a difference.JoMoney wrote: ↑Mon Dec 03, 2018 7:43 pmWhat I've heard, is the primary difference is with the additives/cleaners some brands formulate into their mix that may reduce buildup (but there is some dispute in how much of a difference there is between brands, and how much the difference even matters over the lifespan of a car)willthrill81 wrote: ↑Mon Dec 03, 2018 6:56 pm I've heard that the gasoline at many discount fuel stations is older gasoline that, for whatever reason, didn't get sold in time to make it to the 'premier' stations. But that may be completely false.
FWIW, Costco is listed on AAA's list of top-tier gas:

Among other info:
Fuels with lower-quality additive packages can build up deposits on fuel injectors and on intake valves. Others can build up deposits in combustion chambers and may lead to intake valve sticking. These lower levels of additives can have negative impacts on engine performance and vehicle responsiveness.
Do some brands have higher detergent levels?

The 4% back should work on all regular gas stations, but will not work on grocery store gas stations like Safeway and Fred Meyertexasdiver wrote: ↑Sat Dec 01, 2018 1:58 pm
If you are using the Costco VISA you also get 4% cash back on all Costco gas purchases which has the effect of chopping an additional $0.12 off the price for $3/gallon gas. You don't always get the cash back at stations other than Costco. Depends on the location so if you want to be sure you are getting it you need to buy at Costco. There's been a lot of internet discussion of this point.

Re: Why is Costco gas so much cheaper
Im my hometown, Costco Gas is not usually more than 10 cents per gallon cheaper which doesnt make it worth it to me to go out of my way to Costco.
Where I have noticed the biggest price difference for Costco Gas is in Hawaii. Just left Kona, Costco is on the way to the airport. 80 cents per gallon cheaper than other gas stations. Same was true in Maui, and there are frequently long lines.

Well there you go. Unfortunately around here Safeway and Fred Meyer are the two cheapest alternatives to Costco.alaskantraveler wrote: ↑Wed Dec 05, 2018 2:27 pmThe 4% back should work on all regular gas stations, but will not work on grocery store gas stations like Safeway and Fred Meyertexasdiver wrote: ↑Sat Dec 01, 2018 1:58 pm

Re: Why is Costco gas so much cheaper
Made the weekly trip to Costco yesterday. Gas stations closest to my house on the way there were 2.45. Station two blocks from Costco was 2.39. Costco was 1.99.
People were lined up two cars deep to get to the right side of the pumps. No lines for the left side, where we went and stretched the hose to reach the filler door on the driver's side.

How would this work? The tankers transporting to all of the gas stations pull from the same distributors pipelines.willthrill81 wrote: ↑Mon Dec 03, 2018 6:56 pm I've heard that the gasoline at many discount fuel stations is older gasoline that, for whatever reason, didn't get sold in time to make it to the 'premier' stations.

I have heard that in each tanker truck, each company dumps its own gallon of additives into the entire trailer.
At this point is a commodity.
That doesn't mean a low volume stations couldn't get water or contaminated fuel, just because they don't sell much. This would have to be a very low volume place with a large tank.

Costco also adds additional additives directly at the station. Details can be found online, example here:willthrill81 wrote: ↑Thu Dec 06, 2018 1:25 pmAs I said, it may be a completely false notion.

Re: Why is Costco gas so much cheaper
The detergents can be different, and perhaps they make some difference for some nitch cars over time. The real concern is that the fuel isn’t contaminated, but it doesn’t matter how much you pay that can still happen. Very rare these days though.willthrill81 wrote: ↑Thu Dec 06, 2018 1:25 pmAs I said, it may be a completely false notion.

Re: Why is Costco gas so much cheaper
I track my savings and it's about $1-2 savings for a 10g tank compared to local average prices. Total savings depends on the day. I don't think CostCo is taking a loss, I have read they simply keep it lower than the competition by a few cents. It's honestly so minor that I would not go out of my way to purchase there, but the location is close by my home. Saving $2 really isn't worth waiting in line or driving out of the way.
