Best 5 Gas Stations For Top Quality Gas

Whether you’re planning a road trip or your fuel gauge shows low, you’re not going to escape the fact that you, from time to time, need to fill up that money-guzzling tank to continue your journey. But while doing so, you not only want to choose one of the best gas stations that ranks high on customer satisfaction, you also want to choose one that provides top-quality gas. In other words, one that provides Top Tier approved fuel.

So, to help you with that, we’ve put together a list of the best gas stations convenient for you to visit. But before that, you might wonder, what on earth is Top Tier gas? Let’s find out.

What Exactly Is Top Tier Gas?

Top Tier Gas is a benchmark for fuel quality established through a collaborative program initiated by a group of car companies. The primary vision behind this program is to assist consumers in making informed decisions when purchasing fuel for their vehicles. Not only to protect the engines but also to ensure the consumers get the most efficient, environmentally friendly, and cost-effective fuel on the market.

Where Did It Begin?

In the late 1980s, as new technologies started to take off, many car manufacturers also widely started to use more advanced fuel injectors in new cars. But soon enough, they began to notice an issue: clogging. The problem itself turned out to be inadequate levels of detergent additives in some gasoline. To tackle this problem, they turned to the U.S. Environmental Protection Agency (EPA) for help.

But even after EPA introduced a minimum gasoline detergent standard in 1995, the car manufacturers weren’t satisfied. Their repair records suggested that the amount of detergent in some gasoline wasn’t enough. So by 2002, the automakers made a new attempt by asking EPA to increase the standards. But EPA wasn’t responsive.

As a result, representatives from different automakers decided to go together to set a new standard for higher detergency gasoline than required by regulation, and in 2004, Top Tier Gas was introduced.

What Makes Top Tier Gas So Special?

Even though the term “Top Tier” is widely used for many things, it is a trademark that has become synonymous with premium-grade gasoline that promises more efficiency, better cost-effectiveness, and a lesser environmental impact than other fuels.

Top Tier Gas aims to guarantee that individuals obtain the best available fuel to protect their engines and the environment when they visit their local gas station. Today, even the EPA recommends using Top Tier fuel, although it has 2 to 3 times more detergent than the minimum required by EPA.

However, many seem to believe that Top Tier gas or fuel and its synonymous “premium” has to do with the octane levels, but that’s not the case. You can get Top Tier approved fuel in all three types of octane gradings. So, what does the octane level mean? Let’s take a closer look.

What’s the Deal With Octane Levels?

Octane level or rating is a measure of the fuel’s stability and ability to resist uncontrolled combustion, or “engine knocking,” when ignited under pressure. In other words, a higher octane rating suggests a better and more stable fuel, and vice versa. Regular gas has an octane rating of 87, premium at 93, and super gas at 97.

But what makes these numbers so crucial? To keep it simple, fuel is normally unstable and can either ignite as intended (controlled) by the spark plug or spontaneously (uncontrolled) due to rising temperature and pressure from primary combustion. Often referred to as a “second” uncontrolled combustion, detonation, or knock.

The latter (uncontrolled) is something you want to avoid. So, by adding additional additives (higher octane number), you can achieve a more stable fuel that ignites when supposed to. Not only does this help with engine performance, but also with fuel economy and emission control.

However, not all brands do this. So, just because you see a premium price tag doesn’t mean the quality is better than regular gas. Instead, you’ll want to keep an eye out for gasoline that is Top Tier approved. Furthermore, using higher octane fuel than your car or vehicle requires won’t give any noticeable benefits.

Considering all the above, the next time you get into your car to get some gas, you’ll want to make sure you get the best out of it.

Their gas stations, often adjacent to their massive retail warehouses, are known for their value and quality.

Which Gas Stations Have The Best Quality Gas?

BP, Shell, Chevron, Exxon, Sinclair, and Costco are some of the best places to go when looking for the best quality gas. These are all Top Tier certified and pass the requirements for high-quality fuel performance standards.
