## What is Top Tier Gas and Is It Worth It?

Top Tier gasoline is a type of fuel that includes detergent additives and is the name of a real gasoline standard rather than a marketing ploy. It's advertised as a way to keep your engine and other components clean, but is it worth a potential price premium?

It's a complicated answer. However, the variety of cars on the road this decade necessitates a variety of fuels, and newer vehicles with complex engine management systems, turbochargers, and superchargers have different requirements. All of this has led to making fill-ups more puzzling than ever if you want to get the best performance and longevity from your vehicle.

That's where Top Tier Gas comes in, and many drivers swear by it to prevent engine damage and even break down existing deposits on components. Some studies back it up as more than a gimmick from gas stations and automakers. However, the better the fuel, the greater the cost, and, for some cars, it's a waste of money.

There's a lot to digest, but, ultimately, a persuasive argument not to fill your car with garbage gas. Here's what you need to know about Top Tier gas and if it's right for your car and driving situation.

## What is Top Tier Gas?

Gasoline is already separated into different octane ratings, which indicate the level of compression the fuel can withstand before degrading and causing a loss of performance or, worse, engine damage. Top Tier standards reflect the fuel additives added beyond the octane reading to minimize buildups of impurities that could reduce performance and lead to premature engine failure and is approved by a particular advocacy group.

Like the food you eat, the gasoline you put in your car is crucial. High-quality fuel will help your vehicle last longer, perform better, and get better gas mileage. A study from the American Automobile Association (AAA) of Top Tier gas found that it helps keep engines clean and maintain a better standard of engine performance.

The association's most recent study in 2019 (https://www.ace.aaa.com/automotive/advocacy/top-tier-gasoline.html) discovered that Top Tier gas "left 19 fewer intake valve deposits" and had a modest cost increase over standard-grade fuel. Costs have changed, but the science hasn't changed much — better fuel is better for your engine and can save money in the long run.

While it can be more expensive, its benefits can save you money in the long run. Knowing what Top Tier gas can do for your engine will help you decide if it will be worth it for you and your vehicle.

There are several different varieties of gasoline, all of which are formulated for specific purposes or benefits. Top Tier gasoline was developed to help maintain the complex parts in modern powertrains and older ones reliant on fuel types long banned by the Environmental Protection Agency (EPA). As engines become more complicated, they need to stay as clean as possible, and Top Tier gas was created to help facilitate this process.

Top Tier gas includes several additives and detergents that clean the combustion chamber and fuel delivery system as they run through the vehicle's powertrain. That can help prevent deterioration, oxidation, and the buildup of carbon deposits, reducing an engine's lifespan and performance. Many auto manufacturers even encourage customers to use Top Tier gas to protect parts such as fuel injectors, intake valves, and ignition coils.

## What Are the Benefits of Top Tier Gasoline?

If you have a modern vehicle built by a major automaker like BMW, Ford, Honda, Toyota, or Volkswagen, you want to do everything you can to maintain the engine's performance. Top Tier gasoline is produced using a high fuel performance standard with the right level of detergent and additives for the best, cleanest burn in the combustion chamber. Knowing some benefits of using Top Tier fuel instead of other gasoline brands will help you decide if it is right for you and your car the next time you fill up.

__Cleaner Engine__

The most important benefit to using Top Tier gas is that it can help keep your engine clean and running smoothly. Over the years, things like carbon and debris can get in your engine and cause all kinds of buildup and deposits that will eventually turn into deterioration.

If you use a non-top Tier fuel, you will only be contributing to the issue. The detergents in Top Tier gas keep the engine clean, which has many different benefits regarding the engine's performance.

__Protection for Emissions Equipment__

Emissions components can be costly to replace, and low-quality fuel can release carbon deposits into them, speeding up the deterioration process. If it breaks down, your vehicle won't pass an emissions test and can't be registered in certain states such as California or Massachusetts, or worse, it might not even start (if the catalytic converter is damaged, for example). Top Tier gas is designed to protect automotive emissions equipment and keep your vehicle running as cleanly as possible for a long time.

__Fuel Efficiency__

Any time your vehicle's engine has to work harder to put out the same amount of power, you will an efficiency loss. Keeping costs low will always be necessary if you have a car made by General Motors, Audi, or Mercedes-Benz. Since Top Tier gas keeps your engine clean, it will facilitate better fuel efficiency and more economical performance. While you will pay more at the pump, you could save money in the long run.

__Increased Longevity__

One of the benefits of keeping your engine as clean as possible is that it can increase longevity and help you make the most of your vehicle. Reducing carbon deposits and soot will lengthen the time the engine will run well.

An engine replacement is one of the most expensive automotive procedures you can take on, and most of the time, once the engine goes bad, the car will be totaled. If you want to save money on the overall cost of ownership for your vehicle, Top Tier gasoline could be an excellent option.

The AAA study also revealed that Top Tier gas used over a 1,000-mile course started to remove old deposits on components. That's helpful for owners of older or used vehicles with multiple owners who might not have been as concerned with the engine's condition. Unlike most human organs, it's a rare condition where moderate damage to significant components can be reversed without substantial repairs or replacement.

Other issues come up with older vehicles, especially those designed to run on leaded fuel that began to be phased out of the US by the EPA in the mid-1970s. And modern gas uses more ethanol instead of other additives to substitute for that lead, which doesn’t necessarily affect an engine’s responsiveness, but has a detrimental effect on fuel lines and other synthetic pieces.

## How is Top Tier Gasoline Different From Premium Gasoline?

Most of the time, premium gasoline (91 octane or higher) is the most expensive and boasts the most benefits for high compression, supercharged, and turbocharged engines. However, high-octane fuel and Top Tier fuel are different. Premium fuel has a higher octane level, which means it creates more pressure in the combustion chamber and burns hotter, which can increase the total amount of horsepower that your engine produces.

While some premium fuels have additives and detergents, they will be wrong for some vehicles' fuel systems. Check the owner's manual or sticker inside the fuel door before you use a different type of gasoline, and avoid mixing them. The Top Tier brand of gas is specifically designed to keep your engine clean and is not a hotter-burning gas like premium is.

## How Expensive is Top Tier Gasoline?

Top Tier gasoline will cost more than regular gas at the pump. However, it usually is only about three cents more per gallon than traditional, regular gasoline. When you add up the potential savings in terms of engine maintenance and repairs that can come up due to carbon deposits and other debris in the engine, spending more at the gas station could be well worth it in the long run.

## Which Fuel Retailers Sell Top Tier Gasoline?

Several large fuel retailers offer Top Tier gasoline at the pump. While many brands use their formula, they will all be held to the same standard when it comes to the additives and the desired outcomes. Looking for Top Tier signage at the station will help you see what stations in your area carry it.

Major brands that carry what's considered top-tier gas in the US include 76, Arco, Chevron, Citgo, Conoco, Costco Wholesale, CountryMark, Exxon, Fast Fuel, Marathon, Meijer, Mobil, Phillips 66, QuikTrip, Ranger, Shell, Sinclair, Sunoco, Texaco, and Valero.

## Is Top Tier Gasoline Worth It?

Studies continue to show that cost is the most significant deterrent to Top Tier gas to consumers. As fuel prices become increasingly unpredictable, it's a price many drivers can't stomach every time. While it's passing the buck down the road and setting people up for more expensive repairs at a time when parts are expected to get more costly, too, this is the reality for many people.  

Apart from sticking to regular maintenance schedules as listed by your vehicle's automaker and a mechanic, the fuel that goes in the car is critical. And if you're a classic car owner and always searching for quality parts and checking every mechanical piece, putting fuel that's not what's best for that vehicle almost throws all that work away.

Your vehicle's engine has quite a few sensitive components, many of which are involved in the fuel combustion process. As engine technology progresses, protecting these components and preventing deterioration and carbon buildup becomes more critical. Using detergent gasoline with an additive package like Top Tier Gas helps prevent issues and keeps modern engines safe from poor fuel economy and breakdowns.

Engine problems are the most expensive repairs you can face as a car owner, so using more expensive gasoline with additives might be worth the price. It's a balancing act in 2025, but it is something to consider to prolong the vehicle's life and make regular repairs more palatable. And for those who treat their car like a beloved pet, would you skimp on the best insurance coverage or the best food that will extend your time with them?

That might sound absurd to some, but everyone knows someone who spends a lot of money on gourmet cat food and lavish dog steps, right?
