Should I decarbonize my car's engine?

Asked by 斐婷 Oct 06, 2016 at 01:36 AM about the 2015 Honda Civic Hybrid FWD

Question type: Maintenance & Repair

Should I decarbonize my car's engine? When I went to auto service shop,
the workers always suggested me to decarbonize my car's engine. They
told me that my car has direct fuel with enough buildup, the engine could
misfire. The dealership said the best way to maintain my car is to clean the
carbon from my auto engine. They wanted almost $1,000 for this service. Is
it worth the money to pay the dealer to do it?

From my perspective, it is necessary. Actually, this is an area of debate among technicians and engineers, with the opinions of backyard mechanics thrown in. According to our research, after running 1-2 years (about20000 kilometers), the automobile engine will have performance degradation in different levels: Economic performance degradation, fuel consumption increase, Short of power, fast acceleration not free, Start not smooth, especially in cold start, Excessive exhaust emission, Noise increase, The engine oil turns black fast or even slightly burned, The reason of above phenomenon might be various, but an important factor which can’t be neglected is that the engine has been contaminated. The accumulated carbon makes the engine cant's work normally and coordinately, which resulted in a lower overall performance and the car no longer has a good manipulation ability. It also brings hidden danger to the safe driving.

I must tell you that engine carbon clean divided into two types: one is engine carbon cleaning for repair, the other is engine carbon cleaning for maintenance.

With todays fuels decarbonizing an engine is a waste of money. Use a good fuel additive every 5000 miles and you will keep everything including injectors clean .

Direct injection engines definitely need de-carbonizing. Gasoline is injected directly into cylinder so no gas washes over valves to keep them clean. The buildup of carbon on the valves causes them not to seat properly resulting in misfires, rough idle and loss of power. . $1000 does sound like a lot for a four cylinder engine, though, even though the intake must be remove to do the job properly. I would get another price from a reputable repair shop.

We just completed these jobs on a 2007 Mini, a 2007 A-4 cabriolet with 3.2l engine and a v-10 Audi S8. All three were misfiring and generally running poorly. Decarbonizing cured problems in all three cars.
