I Compared 6 Fuel System Cleaners Over 20K Miles — Only ONE Actually Worked

I Compared 6 Fuel System Cleaners Over 20K Miles — Only ONE Actually Worked If your car feels weaker than it used to, burns more fuel, or idles rough — your fuel system may be clogging long before any warning light turns on. In this long-term test, I compared 6 popular fuel system cleaners over 20,000 miles of real-world driving to find out which ones actually do something — and which ones are just expensive placebo. Carbon and deposits slowly build up inside fuel injectors, intake valves, and combustion chambers. Over time, this restricts fuel flow, ruins spray patterns, and forces your engine to work harder while delivering less power. The result is lower fuel economy, rough idle, and accelerated engine wear — even in cars that still “feel fine.” Across the full 20K-mile test window, only ONE cleaner consistently worked. That cleaner maintained injector cleanliness, preserved spray pattern, and slowed carbon buildup in a way the others couldn’t. The rest showed early deposit return, uneven combustion traces, or declining performance as mileage increased. In this video, you’ll see: Which fuel system cleaner actually held up over 20,000 miles What real injector spray degradation looks like over time Why some well-known additives fail in long-term use And how to protect your fuel system before costly repairs begin If you care about fuel economy, smooth idle, injector health, and long-term engine life, this test may completely change how you buy fuel additives. Only one actually worked. #FuelSystem #CarMaintenance #EngineCare Subscribe to Auto Care Lab for real car tests, oil analysis & maintenance truth 👉    / @autocarelab
