What is Top Tier Gas?

Before we dig a little deeper into the gasoline that you can purchase at Sam’s Club, it’s important to understand exactly what top-tier gas is and how it differs from non-top-tier gas. 

Top tier gas was developed in 2004; the name signifies that the gas in the pump is certified and there is more than the minimum standard required for detergent additives to better protect increasingly sophisticated engines from carbon buildup and deposits on the intake valve. 

The process has allowed automobile owners to use regular fuel while still protecting their engines, increasing fuel economy, and gaining the self-cleansing benefits of this apparently superior product. 

Many car companies now recommend that only top-tier gas is used in their machines, however, some consumers are wondering if top-tier gas really does make a difference in your engine or if it is simply a marketing ploy from the automobile and gasoline industries. 

Unfortunately for your bank account, the research shows that top-tier gas really is better for your car and it is worth the higher price point in the long run as your car will run better and stay healthier for longer if you opt for top-tier gas for your engine. 

What is Non-Top Tier Gas?

Now let’s talk about non-top tier gas. The first and most important thing to understand about non-top tier gas is that it is not bad for your car, it’s just not as good as top tier gas. 

So, your car will still run smoothly and have a long successful life with non-top tier gas. However, you may notice that the engine needs more maintenance, you end up purchasing more fuel over time because the car uses more per mile than with top-tier gas, and unfortunately, you may spend a lot more on repairs over the years. 

There are many gas stations that are still offering non-top tier gas, and if you have never heard of this certification before, it’s likely that you have been using both variations of gas in your car for years without much obvious trouble. 

What Kind of Gas does Sam’s Club Sell?

Sam’s Club does not source fuel from a sole oil company as most gas stations do. Instead, Sam’s Club operates as an unbranded, independent gas station.

While this may seem like they are trying to cut corners, it’s actually a good thing! Sam’s Club still needs to adhere to all of the requirements from the Environmental Protection Agency (EPA), and the National Fire Protection Association (NFPA) which have very strict gasoline requirements. 

Some research even shows that Sam’s Club gas, though not top tier, has its own additives to protect your engine in order to ensure a high-quality gas. 

The company offers the Sam’s Club Satisfaction Guarantee which offers a 100% satisfaction guarantee, i.e. if you are not happy with your purchase, you get your money back. 

That being said, most people won’t be able to tell if they are unhappy with their gas until their car has problems months or even years later, by which point it would be hard to pinpoint exactly what caused the issues. 

Is Sam’s Club Gas the Cheapest?

If you have decided that you trust Sam’s Club’s gas and want to save some money on your next fill-up, you may be wondering if it is the most affordable option. 

It can be quite difficult to compare gas prices between companies as the price fluctuates so much, but overall, Sam’s Club gas prices are typically between 10-20% cheaper than most other stations. 

The exception to this rule is their major competitor, Costco. Even though Costco does over top tier gas, their prices are usually almost $0.25 cheaper per gallon than Sam’s. 

How can Costco do this you ask? Essentially, Costco is undercutting their gas prices in order to drive up business in their stores.

They pride themselves on being your one-stop-shop for literally everything you need in your life, and the plan is to get customers to purchase their gas, as well as their groceries, clothing, appliances, and pretty much everything else when they stop at Costco. 

Sam’s Club could use a similar model, but for some reason, they have decided that lowering their gas prices to meet Costco’s is not financially viable for them at this time.
