The engine sounds a little rough, and it’s sluggish when you ask it to hustle – as though it’s getting a cold. Taking it to the mechanic for a scratchy throat will probably cost you more than you want to pay. So, try some at-home remedies to heal what’s bugging your motor.

Even though the gas companies say their fuels have detergents, carbon and gunk can still build up on the fuel injectors and intake valves. Combustion isn’t as sharp as it should be, so your engine lags.

The automotive aisle is filled with labels promising hope in a jar that will magically floss the system. They must work – right? Only if you are diligent.

We loaded a container of Dura Lube Fuel System Treatment into the gas tank of a neglected Honda Civic and waited to see changes. The company claims the liquid treats the metals in the engine, not the oil.

As the product information indicated on the website, it took a few tanks of gas to notice anything. Or was that to not notice anything?

Our driver isn’t convinced the fuel system additive is the magic pill, but he did say one particular tapping noise is gone. It may be the ounce of prevention keeps the mechanic away. Time will tell for how long.
