Hey fellow Lykker drivers! Is your car feeling a bit sluggish lately? Struggling to overtake even a Wuling Hongguang? Don't rush to blame the high gas prices just yet—it's likely that your engine is clogged with "black gunk"!

Engine carbon buildup is like arterial sclerosis in humans; if ignored, it will eventually cause serious problems. How many of us truly understand the dangers of carbon buildup after years of driving?

If left unaddressed, it not only wastes fuel and ruins performance but can also leave your car stranded. Today, I'll give you some tips on how to spot these "danger signals" of carbon buildup!

Signal One: Significant Loss of Power, Feeling Weak When Climbing Hills or Overtaking

Remember the thrill when you first got your car, and stepping on the gas made you feel pushed back into your seat? Now, no matter how hard you press the pedal, the car still feels anemic and lacks power.

Especially when climbing hills or overtaking, even with the pedal to the metal, the engine sounds like an old ox struggling to pull a cart, unable to muster the energy.

This is the first sign of carbon buildup! Carbon deposits severely affect fuel combustion efficiency, causing poor airflow and deteriorating the fuel injector's atomization effect.Data shows that for every 0.5mm increase in carbon thickness, engine power can drop by about 15%. No wonder that 200 yuan of fuel used to last you 400 kilometers, but now only gets you 300 kilometers.Don't be fooled by the myth that power loss is a normal phenomenon—it's the carbon buildup stealing your horsepower!

Signal Two: Unstable Idle, Shaking Like a "Sieve"

When waiting at a traffic light, does your car shake like it's dancing disco? The steering wheel vibrates so much it numbs your hands, and the whole body of the car is buzzing? Some owners might think this is due to engine aging, but it's actually caused by carbon buildup!

Carbon deposits lead to uneven cylinder compression ratios, preventing the air-fuel mixture in the combustion chamber from burning fully.

For manual transmission owners, it's even worse—unexplained stalling can occur, and in severe cases, the car might stall while coasting in neutral, terrifying the drivers behind you.

I've heard from owners who spent a fortune on spark plug replacements at the 4S shop, only to find the problem persisted. In fact, after cleaning the carbon deposits, 83% of cars saw their idle shaking issues resolved. Don't get scammed again!

Signal Three: Strange Noises, Detonation, and Skyrocketing Fuel Consumption

If you notice your car making "click-click-click" noises during acceleration, along with an unexplained 20% increase in fuel consumption, that's a clear sign of severe carbon buildup!

When carbon deposits are excessive, they can cause the combustion chamber temperature to rise, leading to detonation.

If this continues, not only will you waste fuel, but it can also damage the pistons and crankshaft! Some owners have reported a 2-liter drop in fuel consumption per 100 kilometers after cleaning the carbon deposits, saving over 3,000 yuan a year on fuel! That's no small amount!

Check your exhaust pipe—wipe it with a tissue. If it's as black as coal, that means too much carbon is preventing the exhaust from being fully expelled. Your engine is practically suffocating!

Don't Get Fooled! What's the Most Cost-Effective Way to Deal with Carbon Buildup?

There are plenty of misleading methods for dealing with carbon deposits on the market:

High RPM Brute Force Method: Running the engine at over 4,000 RPM monthly does have some effect, but only on minor carbon buildup. Hardened carbon deposits won't be removed this way.

Fuel Additives as an Intelligence Tax: The 4S shop's recommendation to add fuel additives every 5,000 kilometers is almost as effective as throwing a sugar cube into the ocean when it comes to hardened carbon deposits.

High-Speed Driving to Clear Carbon: Pure nonsense! In fact, urban driving can lead to more severe carbon buildup due to frequent stops and starts, causing engine temperatures to fluctuate.

My Honest Advice: Consider cleaning the carbon deposits after about 20,000 kilometers of normal driving.

In terms of cost, a simple non-disassembly cleaning can cost a few hundred dollars, while a full disassembly cleaning might run into the thousands.

But compared to the high fuel consumption and shortened engine life caused by carbon buildup, this expense is truly worthwhile!

For prevention, try to avoid long periods of idling, choose high-grade gasoline from reputable gas stations, and reduce the habit of sudden acceleration and deceleration.

A special reminder for owners using ethanol-blended gasoline: this type of fuel forms carbon deposits 40% faster than regular gasoline, so the maintenance cycle must be shortened!

Fellow drivers, don't take carbon buildup lightly! It's the "chronic cancer" of your engine! Taking every maintenance seriously is the key to keeping your car running longer and more smoothly.
