Mobil Gas

Starting our discussion is Mobil Gas, a multinational petroleum product brand owned by ExxonMobil. Let us look at the history of Mobil.

Mobil Gas Company History

Mobil gas’ origin dates back to 1911, after Standard Oil’s split, which resulted in 34 different companies. The Standard Oil Company of New York (Socony) was among the companies. Socony merged with the Vacuum Oil Company in 1931, forming Socony-Vacuum. Mobiloil was Vacuum Oil Company’s lubricant brand from 1904, and Socony-Vacuum adopted the brand name.

The firm became the Socony Mobil Oil Company in 1955 and was renamed Mobil Oil Corporation in 1966. A 1999 merger brought together the Mobil Oil Corporation and Exxon, resulting in ExxonMobil. 

Exxon traces its ancestry to the Standard Oil Company of New Jersey, which also resulted from the 1911 Standard Oil split. It grew over the years, taking on several names in the 1960s and 1970s as part of its rebranding strategy. 

Presently, ExxonMobil is among the largest firms worldwide by revenue. Besides gas, the company also deals with other car utilities, such as engine oil, transmission fluid, and oil filters. ExxonMobil has its headquarters in Fairfax, Virginia, with branches in the UK, Australia, New Zealand, Greece, Japan, and other regions.

Mobil gas is popular due to its quality, and many vehicle manufacturers recommend it. ExxonMobil Synergy Supreme+ is a premium gas with a 93-octane rating. This E10 Mobil gas is of high quality and contains a detergent to ensure clean injectors, efficient engine running, and excellent fuel economy. 

Additionally, Synergy Supreme+ has a friction modifier that prevents friction. The outcome is the longevity of the engine parts.

The major downside of Mobil gas is the cost. The cost might be higher than other brands, but it is justifiable, courtesy of the product quality.

Is Mobil Gas Good?

Mobil is a popular brand of gasoline, sold in many countries around the world and known for its high quality and performance. This is also prominent for its environmental friendliness.

So, Mobil gas is a natural choice for those who are looking for high-quality, environmentally friendly gasoline. Not to ignore, it is also a good choice for those who are looking for a gasoline that is known for its performance and efficiency.

However, it is important to note that there are other brands of gasoline that are also high-quality and environmentally friendly. That means you have chance to compare different brands of gasoline to end up with the one that best answer to your needs.

Now, the decision of whether or not to use Mobil gas is a personal one to a significant extent. If high-end, environmentally friendly gasoline is your call, Mobil gas is a good choice coming at a hefty price. On the contrary, if you are on a budget or if Mobil gas is not available in your area, then you may want to consider gasoline produced by other companies.

As for high cost, there are several things in it to compensate that include friction modifiers, injectors-cleaning detergents, and more.

Shell Gas

Shell gas is a product of Shell PLC, a London-headquartered multinational oil and gas company. This company has been in the petroleum product scene for over a century, with several vehicle utilities under its banner.

History Of Shell Gas

Shell came to be in 1907 after the merger of two rival companies: the Netherlands’ Royal Dutch Petroleum Company and the UK’s Shell Transport and Trading Company. The merger was a 60:40 deal, with the Royal Dutch taking 60% of the dual-listed firm’s shares. The main reason for its formation was to venture into the global market dominated by entities like Standard Oil.

This petroleum company grew in leaps and bounds to become the leading oil company worldwide as the 1920s folded. During this timeframe, Shell notably took control of the Mexican Eagle Petroleum Company to form Shell-Mex Limited. This new entity sold Eagle and Shell commodities in the UK. 

In 2002, Shell cemented its association with Standard Oil after acquiring Pennzoil Quaker State Oil Company. The company has been through several ups and downs throughout the 20th and 21st centuries, but it has withered the storm to be among the top companies in the world, ranked by revenue.

How good is Shell gas? Shell does not compromise when it comes to quality, an attribute you will appreciate when you get gas from its outlets. The E15 gasoline contains 15% ethanol, which is lower than most brands, considering it is regular fuel.

The Shell V-Power Nitro Plus is a premium-grade fuel sporting a patented formula. The formula features four defense levels to deal with wear, gunk, corrosion, and friction; as such, your engine and fuel systems will be in excellent shape. 

Apart from gas, Shell deals with other products like engine oil, lubricants, and electric vehicle charging.

The premium V-Power Nitro Plus gas enhances engine efficiency by doing away with gunk, corrosion, wear, and friction. 

The regular Shell gas fuel has E15 rating, or 15% ethanol content. It is a low value, translating to low emissions and smooth operation.

Mobil Vs. Shell Gas Differences

The central part of our discussion focuses on Mobil vs. Shell gas differences. We look at the contrasting points based on various features as highlighted below.

Product Quality

Gas quality is a crucial factor to consider when determining the best fuel for your car. Mobil gas and Shell spare no effort regarding quality, a reason why they are market leaders. Mobil gas has detergent and friction modifiers to boost the engine’s efficiency. 

Flipping the page, Shell gas’ formulation effectively deals with gunk, corrosion, wear, and friction. The Exxon vs. Shell gas quality debate ends in a draw, as both brands bring their best.


Regarding accessibility, we look at the market share and how easy it is to get Shell or Mobil’s services. The accessibility discussion is a tie, as both firms have a decent market share and are present in various regions of the world.

Ethanol Content

Up to 98% of gas used in the USA contains ethanol, whose primary role is oxygenating the fuel to enhance the combustion process. While ethanol is significant, it has high evaporative emissions, which can be destructive to the environment; as such, it is advisable to go for fuel with low ethanol content.

Talking about ethanol, we compare Mobil E10 vs. Shell E15. E10 means the fuel contains 90% gasoline and 10% ethanol, while E15 gas has 85% fuel and 15% ethanol. Mobil E10 is the victor as it contains less ethanol. Shell E15 has reasonable ethanol levels, as per industry regulations.

Still, on ethanol content, Shell stocks the ClearFLEX E85 fuel. It is flex-fuel comprising 83% ethanol and 17% fuel, and intended for flex-fuel vehicles.

Price And Variety 

Price is a crucial factor to weigh when picking an ideal gasoline brand. The Mobil vs. Shell price discussion reveals a tiny margin, as the products cost roughly the same. However, you will notice that Mobil and Shell’s gas prices are higher in some places and lower in others.

Furthermore, the two brands are diverse, with various gas options under their catalog. Both have regular or standard gas, which is less costly than the premium varieties. A look at Mobil Synergy vs. Shell V-power, the premium gas grades of each brand, we see that their quality is almost similar.

Mobil Synergy and Shell V-power have many additives, like detergent, to ensure smooth performance and boost engine life. Shell takes the victory on variety, as it stocks flex fuel, while Mobil doesn’t.

Shell and Mobil gas are among the best gasoline brands in the world and boast a lengthy presence in the market. On the better brand, it is more about your preferences and accessibility as the two companies bring their A-game and offer high-quality products and services.

Both have top-grade products, though Mobil stands out due to its accessibility as it is available in most parts of the world. Nonetheless, some people may prefer Chevron due to its relative affordability.

Is Exxon Mobil Better Than Shell?

Exxon Mobil and Shell tie in several aspects, notably product quality, with several automotive brands recommending them. Exxon Mobil slightly edges out Shell due to its gas’ low ethanol content. Shell has a higher ethanol level, at 15%, but it is within the recommended limits.

Does Shell Have the Best Quality Gas?
