The 10 Best Fuel Injector Cleaners For Every Price Point
Fuel injectors are a crucial component of your fueling system. They are the reason your engine can process and be powered by fuel, which is why they also need routine cleanings to ensure sediment and debris don’t prohibit fuel from reaching your engine.
Fuel injectors take pressurized fuel — in a mist-like state — and spray it in an inlet in the manifold or cylinder. The engine then burns this petroleum-based substance to power your car. Over time, fuel injectors can develop sediment and carbon deposits, decreasing their efficiency and potentially hindering your fuel system and engine’s performance.
It pays to have a good fuel injector cleaner on hand to ensure your fuel system is working correctly. Fortunately, there are many cleaners at various price points with different additional abilities.
Check out these picks of some of the best fuel injector cleaners out there.
