working on engine - technician

Like anything else on your vehicle, keeping various systems clean and in good shape is essential to long life and reliability. Your fuel system is especially important - parts are expensive, problems can be difficult to diagnose, and it doesn’t take much contamination to cause a huge issue. It’s much easier to keep your fuel system clean than it is to clean a dirty or problematic system. Performing regular fuel treatment can prove very beneficial to the life of your vehicle.

Keep your engine running strong - Dirt and debris in the wrong places will restrict fuel flow - it can make your engine run poorly, and even cause catastrophic damage in some instances. A speck of dirt in an injector nozzle can cause the engine to run poorly, or even wash out a cylinder over time, resulting in an engine rebuild or replacement. By taking care of your fuel system and any issues that arise, you can prevent worse problems down the road.

Keep vehicle components in good shape - Fuel lubricates moving fuel system components, making it dually important. Buildup on components will damage moving parts and further contaminate the system. Fuel system cleaning keeps those components clean and in good working order, so they lubricate and operate properly. When components are maintained professionally and correctly, they last much, much longer.

Fuel system treatment doesn’t only affect the fuel system - specially formulated additives keep other components like your valves, oxygen sensors, and so on clean and functioning properly as well.

Keep your vehicle running efficiently - Dirty fuel or fuel that doesn’t flow correctly will wreak all sorts of havoc on the system of sensors that constantly read running conditions and adjust fuel conditions. It can also damage or cause buildup on valves, inside of intakes, etc. When sensors can read conditions properly, or read that there’s a problem, fuel mileage decreases and emissions increase, which will affect your operating costs dramatically. It’s better to keep everything running right.
