The real reason for the high fuel consumption of the Lancer Evolution is excessive engine carbon buildup in the short term. Function of car emblems: The function of car emblems is to facilitate identification of a vehicle's "identity" by sellers, users, maintenance personnel, and traffic management departments. According to Chinese national regulations, these emblems must be inspected during new vehicle registration and annual inspections. Related classifications: Initial letter emblems, brand English emblems, symbolic object emblems - Maserati's trident, Lamborghini's bull, Buick's three shields, Ferrari's horse, abstract graphic emblems, Audi's four rings, Mitsubishi's three diamonds, Renault's diamond, Toyota's three interlocking rings.

When my Lancer's fuel consumption suddenly skyrocketed, I spent some time figuring it out and realized the issue was with my driving habits. I used to keep it in D gear and step on the brake at red lights, thinking automatic transmissions didn't need attention, but the torque converter was constantly struggling. Also, during hard acceleration, the engine would roar with RPMs soaring. Later, I tried maintaining a steady 90 km/h on the highway, shifting gears around 2000 RPM, and my fuel consumption dropped by over 2 liters. Tires are crucial too – last time the pressure dropped to 1.8 bar unnoticed, making the wheels roll like they were glued. Now I check tire pressure monthly, keeping it at 2.3 bar. Clearing out the trunk full of camping gear also saved me 0.5 liters per 100 km.

My Lancer Evolution has been consistently consuming 11L/100km in city driving. One day I casually checked the air filter and was shocked – the filter paper was completely clogged with willow catkins and dust. After cleaning it with a vacuum cleaner, the fuel consumption immediately dropped by 0.8L. Carbon buildup in the throttle body was even worse – when I disassembled it myself and sprayed carburetor cleaner, the valve couldn't close properly due to thick black sludge. Changing the spark plugs made the most noticeable difference – the original nickel alloy plugs had been used for 50,000km with electrode gaps worn to 1.5mm, and switching to iridium plugs significantly improved ignition. I also tested the oxygen sensor – voltage fluctuations exceeding 0.5V after warm-up definitely indicate problems. As for the AC, since last year's refrigerant leak, the compressor has been running at full power, no wonder it adds 1.5L to fuel consumption when turned on.

I once refueled at a small gas station, and the next day my Lancer's fuel consumption shot up to 13 liters per 100km, with black smoke coming from the exhaust pipe. The repair shop said two injectors were clogged with impurities, and after cleaning, everything returned to normal. Later, I learned that this car's direct injection engine is particularly sensitive to fuel quality, and using 95 octane saves 0.6 liters compared to 92 octane. I've also had issues with the mass air flow sensor—its contacts oxidized, causing poor contact and making the ECU misjudge and inject more fuel. A stuck carbon canister purge valve can also steal fuel, especially in summer when you hear a suction sound from the fuel tank. Oh, and don't skimp on engine oil—a friend used low-viscosity oil, which increased engine running resistance and wasted fuel.

My old Lancer used to consume over 14L/100km. An experienced mechanic found the aging PCV valve was causing excessive exhaust gases to enter the combustion chamber. Replacing it with an improved version showed immediate results. A clogged catalytic converter is even worse - increased exhaust backpressure reduces engine efficiency, and the catalyst substrate turned white when inspected with a borescope. The timing chain had also stretched by half a tooth, causing ignition delay and extra fuel consumption. I once upgraded to 225/45R17 wheels which increased rolling resistance and fuel usage - switching back saved 1.2L/100km. Overfilling engine oil is problematic too; after one service, the cold dipstick showed levels above maximum - removing half a liter restored normal fuel economy.
