Shell V-Power Shell V-Power®. Actively cleans for better performance. On today’s tough, demanding roads, performance is what counts. At Shell, we believe all great performances begin with a clean engine. Shell V-Power® premium gasoline can clean up deposits on intake valves and fuel injectors left behind by low detergent gasolines. That’s because it contains more than five times the amount of cleaning agents required by government standards. Shell V-Power is also recommended for vehicles that can benefit from higher octane (check your owner's manual for the octane level recommended for your vehicle.) Try Shell V-Power. It actively cleans for better performance. How Shell V-Power® works under your hood. The power source in today’s vehicles is a sophisticated, computer-controlled engine that operates on a basic four-stroke combustion cycle. That cycle consists of intake of fuel and air, compression of the mixture, ignition and subsequent power, and finally exhaustion of the combustion products. Proper combustion depends on a precise mixture of fuel and air at the time the spark plug fires. A vehicle’s engine needs to draw fuel and air (oxygen) in precise quantities. It’s important the engine has the maximum amount of air and the exact amount of fuel to burn with this air under all driving conditions. Use of low detergent gasolines can allow deposit materials to build up on your engine’s intake valves and fuel injectors. This material can cause less efficient mixing of air and fuel and result in incomplete combustion in some cycles. Tests prove that, with regular use, Shell V-Power can remove those deposits that low detergent gasolines leave behind. Shell V-Power®. Putting it to the test. Shell V-Power® is the result of a three-year development program completed by Shell fuels experts in the US working in conjunction with our global fuels design team. Using experience gained from years of developing specialty fuels for Ferrari, Shell V-Power was carefully designed to be safe and effective for use in all vehicles. It was first tested in the lab on vehicles run on chassis dynamometers. After successfully completing this phase, Shell V-Power was tested for deposit clean up on vehicles in normal service over the road . The vehicles in the lab and road tests included new and old models, domestic and imports, sedans and SUVs, representing a wide array of manufacturers and engine types.
