The difference between Costco and other gas stations is that Costco gas is cheaper. Usually, the price is 60 cents less than a regular Mobil gas station. This price is for one gallon, so if you fill up your tank it adds up and you get a lot of discounts at the end.

But still, at the end of the day, you’ve got to purchase the yearly subscription. And if you are not a Costco regular, you are probably asking yourself, is it worth it?

In our next chapter, we are going to answer your question.

Does A Subscription Pay Off For The Gas Only?

Many people that are not regulars to Costco are asking this question along with how much is gas at Costco? To be honest it’s not cheap to get a yearly subscription. At the end of the day, if this subscription doesn’t pay off, you are losing money.

So, many people have already been testing this and made some testimonials about Costco’s gas prices. And a reader has made simple workings out on a monthly basis.

For example, a gallon of gas at Costco costs around $3.29, and a gallon of gas at a Mobil gas station costs around $3.99 if you pay in cash. Or if you decide to pay with a credit/debit card the gas is going to cost you $4.19 per gallon at Mobil.

And let’s say that you have a car that has a 12-gallon fuel tank and you fill this tank three times a month. This is the math. The first example is with Costco membership and the second example is on standard Mobil gas station.

With Costco Membership

Membership (Per Month) $5.00
Price Per Gallon $3.29
Gallons Of Fuel 12
Monthly Fill-Ups 3
Total Monthly Cost $123

Regular gas station:

Gas Price (Per Gallon) $4.20
Gallons Of Fuel 12
Monthly Fill-Ups 3
Total Monthly Cost $150

This simple math means that you have saved $27 dollars per month, in a full year you save $324. Minus the Costco membership of $60 it means that you save $264 on average for the whole year, or $204 if you go for the premium membership.

A thing to consider is that the gas prices vary during the whole year, this is just a rough estimate. But it’s close enough.

You should also take into consideration the commute time. Because Costco gas stations are not readily available where you live. You need to travel to get there and also spend some money on gas. This will translate into more visits to the Costco gas station. More gas equals more money spent there. And that is the whole purpose of the cheap gas, something that we will discuss later.

With this subscription, you are going to fully enjoy all of their services at a discount price. And one of these services is cheap gasoline as we mentioned in the previous chapter.

Costco implemented a smart way of doing business, by offering cheap gas prices. This was implemented because of the increase in their customer numbers in the markets.

All of these people are going in and out of Costco stores buying products, these products are bringing profit to Costco, unlike the gasoline. The gas station is only there to bring more customers that want cheap gas prices, that’s it.

Is Costco Gas A Good Quality Gas?

We talked above about how much is gas at Costco, now let’s discuss more the quality of their gas. Because at the end of the day you need to fill up your car with quality gas.

Costco’s gasoline is relatively safe for your car.

These are standardized requirements that every gas station should have. They went a step further and have been certified to meet the TOP TIER performance standards, for all of their fuels. And that says quite a bit for their dedication and honesty with their customers.

Also, it is foolish to think that a serious company like Costco will bother to make their gasoline low quality. With this approach, they will instantly start to lose customers, and when people start to go away, it is impossible to bring them back. Costco knows about this and they always try to keep their customers happy with their services. And also establish a good relationship in the process by offering a top-quality product.

From Where Does Costco Gets Its Fuel?

This is an important thing to know because you want to know where is your fuel made. Unfortunately, Costco doesn’t share many details on where they get their gas. On the company site, they say that their gasoline comes from “major refineries”.

These major refineries can be one of the top players in the market when it comes to gas. And for sure this possibility is boosting my trust in their gas. Because you don’t want to add fuel to your car from some third-tier refinery that uses the same old methods that were used in the 1980s.

Modern cars require clean gas. The gas needs to be cleaned from all impurities. When you pour it into a bottle you shouldn’t see anything floating around. Because if you see something that floats, that is bad news for your injectors. With this poor fuel, your car may have trouble running and also make some unpleasant noises. The worst-case scenario is injector damage. And these injectors are known to be pricey.

What Types Of Gas Are Available At Costco?

How Much Is Gas At Costco

In, addition, these three types of gas are the most common across the US. Although there are other options, it’s unfortunate that Costco doesn’t offer these types of fuel. So, if you have a car that is running on a different type of fuel, it is better to look for a gas station that offers them.

Usage of fuel with a low octane rating may result in engine knock. This engine knock is pretty frequent in cars that run at places where fuel has low octane ratings. Some places offer 85 octane gas, but that may be bad for your engine’s overall health and if you run it for long periods of time in this situation. The engine will develop a permanent knock and will wear off prematurely. So, if you want to keep your engine safe, use gas with a higher octane rating.

What Are The Octane Ratings?

An octane rating is a standardized measure of a fuel’s capability against compression. The bigger the octane number, the more compression the fuel injected in the cylinder can withstand before making a detonation.

There is a misunderstanding connecting a higher-octane rating fuel with performance. In reality, the octane rating does not connect directly with the energy content of the fuel. The octane rating simply indicates the fuel capability against compression.

The higher-octane fuels are used in vehicles that make higher compression. And a higher compression in other words translates to a higher power. So, before searching how much is gas at Costco learn more about the octane ratings.

Do I Need To Add Premium Fuel In My Car?

That depends on the engine that you are running on your car. For example, if you are running a high compression engine that requires more octanes, then it is a good idea to add premium fuel. This premium fuel with high octane rating works the best with these types of engines.

These engines that have a higher compression ratio can be found in some high-performance applications and sports cars.

If you don’t have a sports car and you are driving your regular car, adding premium fuel to your tank will not improve your performance. Because your car was standardized to run regular gas at 89 octanes.

If you add premium fuel, you probably will feel a slight improvement but not much, like the people that are running sports cars are seeing.

So, it’s the best idea to not spend more money on fuel without any real reason.

Does Costco Gas Contain Ethanol?
