It’s risky to fill up your automobile with gas at any old station. Before it’s too late, find out what the Top Tier Detergent Gasoline standard is.

This author has been carefully screened to ensure that he or she is qualified to write about the subject at hand. Please visit our “about” page for more information.

For the most part, going to the gas station is just something we do on a regular basis, and we usually pick the one closest to us or the one with the best deal.

However, have you ever given any thought to which gas stations offer the greatest quality fuel?

It’s not uncommon for gas stations to use the same fuel source, thus the formula doesn’t alter much.

Top-tier stations, on the other hand, like Shell, Mobil, Chevron, Costco, and Sinclair, employ additives in their own blends of fuel. Engine life may be extended by the use of detergents, friction reducers, and corrosion inhibitors.

The good news is that we’ll begin by explaining what a Top Tier gas station means for you in the context of your travel plans.

As a follow-up, we’ll go over what octane levels are and why they’re important, and how fuel additives work and how they might help your vehicle.

We are ready to go now.

What Is Top Tier Gas?

In order to be designated as “Top Tier,” a station must meet a particular quality of performance.

Top Tier gas has the following features:

To qualify for the Top Tier program, all retail establishments must meet certain criteria.

A detergent ingredient permitted by Top Tier is included in all gas grades.

No organometallic additions such as Ferrocene or MMT are used.

There are now 52 retail brands that fulfill the Top Tier criterion, which means you’re likely to find one close by.

Is the higher cost of Premium petrol really worth it? 1000 hours of continuous engine operation equals approximately 4,000 miles of driving.

Afterwards, the engine was dismantled and examined in detail. There were 19 times less carbon deposits in Top Tier gas than in ordinary fuel, according to the study. This, in our opinion, is a compelling argument in favor of paying the extra 3-4 cents for Top Tier gasoline.

What’s The Deal With Octane Levels?

Everyone has experienced the dilemma of deciding whether to fill up their automobile with Regular or Premium at a gas station. In what ways are they similar and how are they different?

If the fuel bears the Premium label, it usually signifies that it is more efficient, as measured by its higher octane rating.

To put it another way, this has to do with the pressure gasoline can handle before it starts to ignite. The higher the number, the greater the capacity and, thus, the greater the output of electricity.

Octane ratings for premium gasoline range from 90 to 95, while regular gas is normally around 85.

Some cars can have performance concerns if they aren’t operating on premium fuel, and vice versa. To find out what the manufacturer recommends, the best place to start is through your vehicle’s owner manual.

Does an automobile intended to run on 87-octane gasoline run on 90-octane? Some engines may potentially be harmed by increased efficiency. For this reason, sticking to the original purpose of your vehicle is the wisest course of action.

Top Tier stations include additives in their normal fuel regardless of whether or not you’re paying for premium. Let’s take a look at some of the additives out there and see how they might assist your vehicle’s engine.

Which Fuel Additives Should I Avoid Using?

You can be sure that the fuel you buy from a well-known gas brand contains additives. In the current market, it wouldn’t have been able to compete. Compounds like these are designed to extend the life of your engine while also enhancing performance and efficiency.

Detergents, friction reducers, and corrosion inhibitors are just a few examples.

Detergents are formulated to eliminate deposits while also preventing new ones from accumulating. Friction reducers do exactly what they say they do, reducing the amount of wear and tear on the engine and increasing its lifespan. Corrosion inhibitors slow down the rate at which metals corrode.

Additives come in a variety of forms, all of which are designed to improve the health and lifespan of your engine.

The Top 5 Best Gas Stations

For more than a century, the Shell brand has been synonymous with quality and innovation. As you might expect, they’ve gained a great deal of knowledge about gas as they’ve gone along.

Shell gas has a nitrogen-enriched composition that makes it appealing. Which they claim removes deposit buildup and prevents further growth, according to their claims.


Mobil is one of the most well-known names in the industry when it comes to high-quality gasoline. When Exxon Mobile merged with Exxon in 1999, it became the world’s largest oil company.

Mobile Synergy, a proprietary blend of nine chemicals, is the key to their success. Three different detergents, a friction modifier, and a corrosion inhibitor are just a handful of the many options available.


Costco is a one-stop shop for just about anything, and they started selling petrol in 1995. Costco gas is not only certified as a Kirkland Signature product, but it is also a Top Tier product.

Costco gas has the advantage of being high-quality while also being less expensive by as much as 21 cents a gallon.


Sinclair Oil and Refining Corp. was formed in May 1916 after the merger of 11 local oil firms. Over the past 104 years, Sinclair has grown to more than 1,300 stations around the country.

An ingredient called Dinocare is included in Sinclair gas to improve the performance of your vehicle’s engine. Reduced engine deposits, improved fuel economy, and fewer annual maintenance expenses are all part of this effort.


In 1879, Chevron gas was introduced to the world. As a side note, they’re the company behind the endearing talking automobile ads.

In order to break down, clear out, and avoid carbon buildup, they’ve given their patented fuel additive mix the name “Techron.”

Which Gas Station Have The Best Quality Gas?

If it bears the Top Tier emblem, you know you’re dealing with a reputable company.

However, it is totally up to you to decide whether to fill your tank with Regular or Premium fuel. Consult your owner’s handbook to learn what your particular engine is capable of.
