What is Gunk?
Gunk is another name for carbon deposits that can build up on intake valves and fuel injectors, which can make your engine work less efficiently. Shell V-Power® NiTRO+ has seven times the cleaning agents required to meet federal standards and removes an average of 70% of baked-in deposits left by lower-quality premium gasoline, starting with the very first tank.** Shell V-Power® NiTRO+ provides unsurpassed protection against gunk to help improve engine performance.
The intake valve on the left is protected by Shell V-Power NiTRO+, the one on the right by a lower quality premium gasoline. Intake valve deposit results based on a 10,000 mile vehicle fleet test of part fuel injected vehicles comparing Shell V-Power NiTRO+ with lowest additive concentration (LAC) gasoline.
What is Corrosion?
Corrosion is caused by moisture and other contaminants that can make their way into a vehicle’s fuel tank. It can impact the fuel pump, fuel lines and fuel injectors. Furthermore, formation of particles from corrosive processes such as rusting of steel surfaces can contribute to the blockage of fuel filters, impacting overall vehicle operation. Shell V-Power® NiTRO+ is formulated with a unique agent to provide unbeatable protection against corrosion.
The image on the left demonstrates protection from corrosion with Shell V-Power NiTRO+, the one on the right, by a lower quality premium gasoline. Corrosion results using ASTM D7548/D665 using corrosive saltwater. Results depicted may not reflect what consumers will see in their vehicles under normal driving conditions.
What is Wear?
Wear can occur slowly, over time, when two metal surfaces rub against each other, leading to loss of metal from those surfaces. This can occur in the piston assembly, fuel pump and fuel injectors and can cause higher oil consumption, loss of power and higher emissions. Shell V-Power® NiTRO+ provides our best protection against wear and tear in your engine.
The wear results on the left demonstrate protection with Shell V-Power NiTRO+, the one on the right by a lower quality premium gasoline. Wear results obtained using ASTM D6079 comparing Shell V-Power NiTRO+ with lowest additive concentration (LAC) gasoline. Results depicted may not reflect what consumers see in their vehicles under normal driving conditions
What is Friction?
Friction in your engine occurs as piston rings move against cylinder walls, generating heat, wasting energy, and reducing the overall efficiency of your engine. Too much friction can also damage metal surfaces, increasing wear on critical engine parts. Our proprietary Shell SmoothGlide Technology™ provides our best protection against friction by filling in the rough spots in your engine, forming a protective layer to help reduce friction and improve efficiency.
