I’ve had a few questions recently about the Costco fuel and their gas/fuel stations. Believe it or not, this wasn’t really an area where I had done much research or posting about before. You’d think after eight years of writing this blog there would be no Costco subject left that I hadn’t talked about, wouldn’t you? My extent of “research” was that it was where we always filled up our cars and motorcycles when we were in the US and it was always less expensive than going to nearby stations. So, my research was not too invasive. But now I know everything and then some, and soon you can too.
When I was looking for answers for some readers I discovered that you can find out everything you’ve ever wanted to know about Costco’s Kirkland Signature gasoline (petrol or fuel depending on where you are at) online. They even have videos! Honestly, there is probably more here than you would normally want to know about where you fill up your car, but it is actually kind of interesting.
Costco stations are also equipped to make sure that the vapor from refuelling your vehicle stays contained. The systems at Costco work in conjunction with the Onboard Refueling Vapor Recovery (ORVR) required in vehicles sold in the US since 2001. This means that the vapor stays in your car and doesn’t pollute the environment.
I think the biggest environmental protection that they equip their stations with though, is the continuous monitoring of their underground fuel storage system for leaks. The whole system is electronically monitored for any type of leak and will automatically shut down the entire system if a leak is detected. The whole system is monitored on a continuous basis by Costco employees, as well as an outside monitoring service. Since the underground storage tanks and all piping are made with corrosion-proof, double-walled construction, you would think a leak would be unlikely, but it is good that they are constantly on the alert.
But it isn’t just all about safety when you’re buying gas, but you always need to know that what you are buying is actually good for your car. Both grades of gasoline sold at Costco – Regular Unleaded (typically 87 octane) and Premium Unleaded (typically 91 octane) – meet and exceed TOP TIER requirements, which means vehicles from a Rolls to a Smart will be happy running the Costco fuel. Here’s a quote from the Costco fuel website with a little more about that:
As our valued member, you expect Costco to always offer the finest quality products at the best possible price. Gasoline is no exception. Costco has closely studied fuel additives and engine deposits, and conducted extensive engine tests at nationally-recognized laboratories. As a result, we decided to increase the detergent additives in our fuel to provide a better value to our members. As of March 2014 Costco is listed as a TOP TIER™ gasoline retailer. Find out more at http://www.toptiergas.com/retailers/.
Kirkland Signature™ Gasoline contains five times the EPA detergent requirement in both regular unleaded and premium grades. Kirkland Signature™ Gasoline helps remove any existing deposits and keeps your engine clean.
Keeping your engine tidy might just sound like something crazy that Martha Stewart worries about, but it is something we all need to consider and take steps to do. Keeping your car clean on the inside is important to getting optimal fuel efficiency, while causing the least amount of pollution through emissions. Not to mention, it will also leave your car sounding and running better, and should help with engine maintenance. A clean car is a happy car!
One of the specific questions I received was about where Costco has diesel fuel available. Luckily, I now have an answer for that one. They have a page that lists all of the diesel fuelling stations in the US. Currently, they have 45 Costco stations that sell diesel fuel, so you might not find one near you, unfortunately. But at least now you will know before you get to the store.
Mostly the locations in the US have gas stations now, though not all do. You can always check Costco.com to find the locations in the US that have gas stations. But in the rest of the world it is much more rare. In the UK just
a single three locations in Liverpool, Bristol, and Oldham have petrol stations. I don’t have a car here but I do sometimes have to fill up my Zipcar and would love it if we could do it at Costco just for the convenience. Japan has four gas stations currently, at locations in Chubu Airport, Hashima, Imizu, and Kaminoyama. I do not believe any of the locations in Korea, Taiwan, or Mexico have gas stations. I’m not sure if this is because of local regulations or something else though. The new Madrid (Getefe) location in Spain has a fuel station, but not the location in Seville. I’m wondering if they are thinking of adding a station in Seville or if that is not possible. Five of the locations in Australia have petrol stations. If you are looking for a list of the locations in Australia that have stations, you can check the Costco Australia website (and get hours too). Costco Canada also seems to have a high number of gas stations, but I’m guessing by the fact that they have a list online, that not all Costco locations also have a gas station; just 55 of the locations in Canada have gas stations.
You can find out all about the Costco Kirkland Signature Gasoline and their stations online. Each country that has a gas/fuel/petrol stations has a webpage where you can find out about the stations and fuel in your area (though, they are pretty much all the same content it seems to me). Here is a list of those sites:
Each of these sites has a FAQ that covers important questions you might have about paying and safe refuelling practices. They even have an answer to the question about a mobile phone being able to start a fire with gasoline vapor. No, as it turns out because there’s just not enough voltage and nowhere in the world are no confirmed cases of mobile phones igniting gas vapor. They do of course point out that you are less attentive while talking on the phone, so you should probably put it down to safely refuel and pay attention to what you are doing.
And if you read through all of that information and still have questions about the Kirkland Signature gasoline, you can email them. You can also email them about their diesel fuel to get your questions answered.
