Why does Shell continue to develop new fuels?

Shell is dedicated to continuous product improvement and innovation. Advanced engine technologies are coming to the market, and consumers are keeping their cars longer. Consumers are becoming increasingly conscious about the quality of the products they put into their vehicles because they want to protect their second largest investment. Hence, the increased need for a gasoline that can protect critical engine parts.

Shell Nitrogen Enriched Gasolines provide 20 percent more active cleaning agents than before, and are designed to protect engine’s intake valves and fuel injectors from performance-robbing carbon deposits or “gunk”. So no matter what you drive, no other gasoline protects your engine better than Shell Nitrogen Enriched Gasolines in ALL three grades.

At Shell, we have an extensive research program dedicated to continuous product improvement and innovation, striving to provide drivers with gasolines that can improve their vehicles’ performance. Our experts spend countless hours listening to consumers to better understand their needs.

We also work with the industry, such as auto manufacturers, allowing Shell to understand the needs of changing vehicle technologies and driving product development for improved performance. With Shell Nitrogen Enriched Gasolines, consumers can enjoy an improved cleaning system in ALL three grades of gasoline (Bronze, Silver and Shell V-Power® NiTRO+). 

What vehicles benefit the most from using Shell Nitrogen Enriched Gasolines (sports cars, compact cars, trucks/SUVs)?

No matter what you drive, Shell Nitrogen Enriched Gasoline works in all types of engines, both conventional and modern.

In conventional engines, the unique, patented Shell Nitrogen Enriched Cleaning System cleans and protects intake valves and fuel injectors, so the engine can perform at its best. In modern engines, like direct injection and turbo-charged, fuel injectors are subject to greater heat and pressure, which can cause a breakdown of cleaning agents. The Shell Nitrogen Enriched Cleaning System is designed to maintain thermal stability and work under extremely hot engine temperatures, actively protecting against performance-robbing gunk.

You said Shell Nitrogen Enriched helps improve engine performance as you drive. What does this mean?

The Shell Nitrogen Enriched Cleaning System uses a patented molecule, which cleans and protects intake valves and fuel injectors. Enriching the molecule with nitrogen makes it more thermally stable and therefore more effective in tough engine conditions with higher temperatures and increased pressures. This is particularly important in modern fuel-efficient engines. The Nitrogen Enriched Cleaning System gives all three grades the ability to clean up performance-robbing gunk from intake valves and fuel injectors. Industry data indicate and car manufacturers recognize that a clean engine is more fuel-efficient, produces fewer emissions and allows vehicles to perform at their best.

What does nitrogen do and how will it help the performance of my vehicle?

The Shell Nitrogen Enriched cleaning system uses a patented molecule, which cleans and protects intake values and fuel injectors. Enriching the molecule and the overall cleaning system with nitrogen makes it more thermally stable and therefore more effective in tough engine conditions with higher temperatures and increased pressures.

This is particularly important in modern fuel-efficient engines. The Nitrogen Enriched cleaning system gives all three grades the ability to clean up engine gunk on critical engine parts, and auto manufacturers recognize that a clean engine is more fuel efficient, produces fewer emissions, and allows vehicles to perform at their best.

Where does gunky build-up on an engine come from?

Carbon deposit build-up on critical engine parts is the result of various chemical processes that occur in the engine during its operation. These processes can create a residue, which consists of carbon particles that may build up on intake valves and fuel injectors. Shell Nitrogen Enriched Gasolines are designed to actively shield to help keep your engine clean and protect it from this performance-robbing gunk.

Is engine gunk harmful?

Gunk on intake valves and fuel injectors can result in deposit-related drivability problems. Gunk acts like a sponge, absorbing and trapping gasoline, and making the combustion less efficient. Industry and literature data also refer to potential engine performance problems. The industry data indicates that a cleaner engine can perform as originally designed, making it more fuel efficient with lower emissions. Shell Nitrogen Enriched Gasolines contain a patented formula exclusive to Shell designed to actively shield against performance-robbing gunk in all three grades.

Why is it important for companies like Shell to develop technologies and products that support today’s engine technologies?

We work with car manufacturers to gain good insights into upcoming engine technologies. As a result, we know that some new engine technologies, including direct-injection, present specific challenges that must be managed to help maintain optimal vehicle performance. For example, today’s direct-injection engines expose fuel to higher temperatures and require more thermally stable products like Shell Nitrogen Enriched Gasolines to protect critical engine parts and maintain performance because even small disturbances caused by gunk can have negative impacts.

Since Shell Nitrogen Enriched Gasolines clean up engine gunk in all three grades, what makes Shell V-Power NiTRO+ different?

Shell V-Power NiTRO+ is our best, most advanced product. It contains the highest concentration of the Nitrogen Enriched Cleaning System to provide maximum protection against performance-robbing gunk for optimal performance. Shell V-Power NiTRO+helps to seek and destroy engine gunk that lower-quality gasolines can leave behind faster than other grades of Nitrogen Enriched Gasoline. Shell V-Power NiTRO+ has been successfully tested in today’s modern direct injection engines, proving that this new cleaning system performs under the toughest conditions found in these engines.  Shell V-Power NiTRO+ provides the BEST TOTAL engine protection you can get.

I see all brands collecting fuels from the terminal - so aren’t all fuels the same?

There are actually two key components to a gasoline—the base fuel and the additive system. Base fuel quality is generally the same in an individual terminal. However, Shell blends a unique and patented additive package with enriched Nitrogen into all three grades of Shell gasoline before it is dispensed from the terminal. The Shell Nitrogen Enriched Cleaning System contains a patented formula, exclusive to Shell that cleans and protects intake valves and fuel injectors from gunk left behind by lower quality gasolines.  No other gasoline protects better!
