Is Costco Gas Better Quality Than Sam’s Club?

Costco and Sam’s Club both offer decent options. However, Costco has an edge over Sam’s Club when it comes to the quality of their gas.

Costco gasoline is certified as “Top Tier,” which means it has a higher quality than even the EPA requires.

Top Tier gasoline contains more detergent additives that help clean your engine and prevent buildup of harmful deposits.

According to a study by AAA, Top Tier gasoline can improve fuel economy and reduce emissions.

On the other hand, Sam’s Club gasoline meets all federal and state standards, but it is not certified as Top Tier.

This means that it may not have the same level of detergent additives as Costco’s gas, which could result in a buildup of harmful deposits in your engine over time.

It’s worth noting that both Costco and Sam’s Club sell gasoline that meets minimum federal and state standards, so you’re not going to damage your car by using either one.

However, if you want to keep your engine running smoothly and efficiently, it’s a good idea to choose Top Tier gasoline like the one sold at Costco.

In addition to the quality of gasoline, there are other factors to consider when deciding where to fill up. For example, Costco only sells Top Tier gasoline, while Sam’s Club offers both Top Tier and non-Top Tier options.

Are there any benefits to using Costco gas over Sam’s Club gas?

Both Costco and Sam’s Club offer good quality gas, but Costco’s gas is TOP TIER™ certified, which means it has more detergents and additives that help keep your engine clean.

On the other hand, Sam’s Club gas is not TOP TIER™ certified.

While this may not make a significant difference in the short term, over time, the extra detergents and additives in Costco’s gas may help keep your engine running smoothly and potentially save you money on repairs down the line.

Overall, if you are someone who uses a lot of gas and wants to save money in the long run, it may be worth it to get a Costco membership for their consistently lower gas prices and TOP TIER™ certified gas.

However, if you don’t use a lot of gas or don’t want to pay for a membership, Sam’s Club gas is still a good option.

Costco Gas vs. Sam’s Club Gas: Comparison

When it comes to buying gas, warehouse clubs like Costco and Sam’s Club can be a great option for saving money. Both retailers offer discounted gas prices to their members, but which one is better?

Let’s take a closer look at the price and fuel quality of Costco gas versus Sam’s Club gas.

#1. Price

One of the biggest draws of buying gas from a warehouse club is the discounted price. According to a study by ABC7 News, Costco gas averages $0.20 less per gallon than the national average cost for gasoline.

Sam’s Club also offers discounted gas prices to its members, but the exact savings can vary depending on location.

To get the most out of your warehouse club membership, it’s important to consider how often you fill up your tank.

For example, if you fill up your tank once a week, the savings from a warehouse club membership may be worth it. However, if you only fill up once a month, the savings may not be as significant.

#2. Fuel Quality

Another factor to consider when deciding between Costco gas and Sam’s Club gas is fuel quality. Both retailers offer Top Tier Gas, a better-quality formulation that helps maintain car engines.

However, Costco only sells Top Tier Gas, while Sam’s Club offers both Top Tier and non-Top Tier gas options.

It’s also important to note that some cars require premium fuel to run correctly and may suffer from performance issues running on anything less.

If your car requires premium fuel, it’s worth checking if your local warehouse club offers it and at what price.
