Shell Vs Chevron: Who Has The Better Gas In 2023? - Car, Truck And Vehicle How To Guides - Vehicle Freak (2023)

When choosing what fuel to fill up with, most drivers take three things into consideration: the price, the gas station location, and the quality of the fuel.

With fuel prices on the rise, drivers are often finding themselves opting for the cheapest fuel but this may not always be what is best for your car. You may be wondering who has the better gas in 2022, Shell or Chevron?

Chevron and Shell are Top Tier fuels, this means they meet the high standards for cleanliness and performance set out by Top Tier. The two companies offer the identical quality of gas for drivers, but we’ve picked Shell as the winner due to slightly better customer service and benefits.

In this article, we will compare the two fuel brands and also take a look at Top Tier Gasoline and discuss its many benefits.

What Does Top Tier Mean in Gasoline?

All gasoline must meet certain standards to be sold to retailers and drivers, but some companies produce cleaner gas than others. Oil refineries often sell their gas to various companies, however, not all fuel that drivers put into their cars is the same.

Gas can come from the same refinery but be different at the pumps in the gas station due to different brands using different fuel additives. Gasoline alone can cause damage to modern-day vehicle engines and fuel additives are needed to prevent carbon build-up in the intake valves and fuel injectors.

Each gasoline company uses its own unique blend of fuel additives. Detergents and fuel stabilizers are two additives often used to help prevent the build-up of carbon deposits inside the engine.

When drivers use poor quality gasoline with a poor blend of additives the vehicle will suffer from bad fuel economy, reduced power, and irregular injection of fuel into the cylinders.

Over the years, fuel injection technology has changed and developed and the gasoline without plenty of additives was no longer up to the job. Gasoline without enough additives may power a vehicle but it was found to be causing carbon build-up and clogging the engine.

(Video) Shell vs Chevron Can You Guess Who's Gas Is Best?

Top Tier Gasoline was founded in 2004 and is recommended by auto companies including Ford, Honda, Fiat, Chrysler, BMW, General Motors, and several other well-known names in the automobile industry.

Ten car companies recognized the need for cleaner gasoline in preserving the health of vehicle engines and together they back the standards set by Top Tier Gasoline.

It is important to note that Top Tier gasoline and Premium gasoline are not the same things. Top Tier is gas that meets specific standards for engine cleanliness and performance, whereas, Premium gas is high octane fuel.

Top Tier Gasoline uses higher levels of detergent additives than standard gasoline. These additional additives help to reduce carbon buildup throughout the engine and will improve the overall performance of your vehicle.

Here is a list of benefits of using Top Tier gasoline:

  • Keeps valves clear of intake deposits.
  • Better at cleaning the engine than standard gasoline.
  • Improves fuel economy.
  • Supports better engine performance over time.
  • Prevents the negative effects of carbon buildup inside the engine.

What Are the Top Tier Brands of Gasoline

Over 50 gasoline brands in the USA meet Top Tier standards of cleanliness and can be sold as a Top Tier gasoline brand. Shell and Chevron are just two of the many Top Tier gasoline brands.

A full list of companies meeting this high standard for fuel can be found on the Top Tier website, but here are a few fuel companies that are meeting the Top Tier standards in 2023:

With over 50 fuel companies selling Top Tier gasoline, you may be wondering who is selling the poorer quality fuel.

Often, off-brand gas stations will not be selling Top-Tier gasoline, this is because of its high price tag when it comes to production and purchasing. The big-name brands can afford to pay the extra to bring this better quality fuel to their customers across the country.

Gasoline companies can not just use any blend of fuel additives to become a Top Tier brand. If a fuel manufacturer or retailer wants the seal of approval as a Top Tier gasoline brand, their fuel and gas stations must meet the following standards:

  • All of the gasoline grades must be treated with a Top Tier approved detergent fuel additive.
  • The Top Tier detergent gasoline additive must be added at the correct concentration.
  • Retailers must agree to not use organometallic additives, including MMT and Ferrocene.
  • Every retailer location must meet the Top Tier program’s high standards.
  • There must be a Top Tier logo clearly displayed.

Shell vs Chevron – Who Has The Better Gas In 2023?

Now we have looked closely at Top Tier gasoline and have established both Chevron and Shell sell this higher quality fuel, let’s take a closer look at these two companies to try and determine who has the better gas.

To decide which gas is best for your car really depends on what kind of vehicle you are driving and what engine it has. Different engines will require gas with a certain octane rating.

The fuel octane rating is used to measure the engine’s performance, it indicates the level of pressure the gas is able to withstand before it ignites. The higher the Octane rating, the more pressure the fuel can withstand and the more powerful drivers can expect to achieve.

Shell And Chevron Octane Ratings

Here is a list of the different grades of fuel provided by Chevron. We have also noted down each grade’s Octane rating to help you to make your decision:

  • Chevron Regular – 87
  • Chevron Plus – 89
  • Chevron Supreme – 91

All Chevron gasoline uses Techron, an additive that improves acceleration, maximizes mileage, minimizes emissions, and protects engine parts from carbon buildup.

To help you compare, here are the Shell fuel grades and Octane ratings:

  • Shell Regular – 85
  • Shell Plus – 88
  • Shell V-Power Nitro+ Premium Gasoline – 91

If you are unsure what Octane fuel to use, refer to your owner’s manual. It is important that you use the correct octane gasoline, as using a fuel with a rating that is too high or too low may impact your vehicle’s performance.

High octane gasoline is often recommended for engines that use a higher compression ratio, or use turbo or supercharging to inject more air into the vehicle’s engine. In these vehicles, Shell V-Power Nitro+ Premium would be the best choice.

Shell And Chevron Price

Fuel prices are constantly changing. As the price of oil fluctuates, so do the prices at the gas station. Shell and Chevron do not vary massively in price and both fuels are great value for money, thanks to the cleaning additives they use to protect your vehicle’s engine.

Chevron customers can save up to 7 cents per gallon by becoming Techron Advantage credit card members. Drivers can save even more when filling up with Chevron if they become Visa Techron Advantage credit card members.

Shell credit card members can also save money on their fuel, the reward system enables drivers to save between 5 and 10 cents per gallon.


Is Shell gas better?

Shell gas is a Top Tier gasoline and is better than off-brand gasoline as it uses additives to keep the engine clean.

The Shell V-Power is a great choice for vehicles needing high octane fuel and can be beneficial for cars with turbo and supercharging injectors. Shell has regular, mid-range, and premium fuels, all of which adhere to the high standards set by Top Tier Gasoline.

What oil is better Shell or Chevron?

There is not much difference between Shell and Chevron fuel. The best option for you will depend on what Octane rating your car needs. Fuel prices are constantly changing and often when choosing between Shell or Chevron, it is a case of which gas station is closest or who has the cheapest fuel that day.

Chevron uses Techron to maximize engine performance and minimize emissions and Shell claims to be the best fuel on the market for protecting engines from gunk build-up.

Is Costco better than Chevron?

The gas sold at Costco meets the high standards set by Top Tier gasoline. This means that the fuel is not overly different from Chevron, both brands must meet high detergent levels and standards to be certified Top Tier.

Customer reviews online show little difference in satisfaction and performance between Costco and Chevron. You may save yourself a few cents by filling up at Costco but the fuel isn’t any better than that sold by Chevron.


In the debate of which fuel brand is better, Chevron or Shell, there is not one hands-down winner, but Shell inches ahead very slightly with better customer care and reduced gas cost initiatives.

When choosing who has the best gas, there really isn’t much difference between Shell and Chevron. The high octane premium range of their gasoline can vary in its octane rating and this may influence drivers of high-performance cars.

Both Chevron and Shell offer reward systems for their customers. Chevron customers can save up to 7 cents per gallon with the Techron credit card and Shell uses a similar initiative, with their credit card members able to save between 5 and 10 cents per gallon.
