✅ 1. Carbon Cleaning (Engine Detox)
Best for: Restoring power and improving combustion efficiency.
Carbon Flush - Hydrogen Carbon Cleaning (or HHO cleaning): A machine feeds hydrogen and oxygen into the intake system to remove carbon buildup from combustion chambers, valves, pistons, and the exhaust side.
Chemical Intake Cleaners: Professionally sprayed into the intake while the engine runs (e.g., Liqui Moly, Wynns, BG products).
Benefits: Smoother idle, restored throttle response, lower emissions, and better fuel economy.
🔧 Recommended every 30,000–50,000 km.
✅ 2. DPF/EGR/Turbo Cleaning (for Diesel Engines)
Best for: Diesels with poor fuel economy or power loss.
DPF Regeneration: Forced regen using diagnostic tools or off-vehicle cleaning.
EGR Valve Cleaning: Removes soot buildup causing hesitation or stalling.
Turbo Vane Cleaning: Restores turbo boost efficiency.
💡 These components often get clogged over time, especially on short-distance driven diesels.
✅ 3. Fuel System Cleaning
Best for: Improving injector spray pattern and combustion.
Injector Cleaning: Via additive or direct injection cleaning (e.g., pressurized system flushes).
Fuel Additives: Use high-quality cleaners like Liqui Moly, Techron, or BG44K every few months.
🛢️ Helps remove deposits from injectors, fuel lines, and combustion chamber.
✅ 4. Oil System Flush
Best for: Reducing sludge and improving engine lubrication.
Use an engine flush additive before your next oil change.
Follow with high-quality synthetic oil with good detergent properties.
🛠️ Sludge buildup can affect oil flow and cause power loss.
✅ 5. Replace or Clean Critical Filters
Best for: Ensuring optimal airflow and fuel delivery.
Air Filter: Dirty filters restrict air, reducing power and economy.
Fuel Filter: Replacing improves fuel flow and injector lifespan.
Cabin Filter: Not directly engine-related, but improves HVAC system efficiency.
🌬️ Simple, inexpensive, and often overlooked.
✅ 6. Spark Plugs & Ignition Coils (Petrol Engines)
Best for: Better combustion and smoother acceleration.
Worn plugs reduce power and increase fuel consumption.
Replace every 40,000–100,000 km depending on type.
⚡ Critical for consistent ignition and efficient fuel burn.
✅ 7. ECU Recalibration / Software Update
Best for: Optimizing engine performance and economy.
Dealership or performance tuner such as Unique Motorsport can reset adaptive learning or install latest firmware.
On some vehicles, an ECU remap may improve fuel efficiency.
💾 Ensure it's done by a reputable technician.
✅ Bonus Tip: Drive Cycle Adjustment
Best for: Maintaining a clean engine long-term.
Combine short trips with occasional long-distance drives to allow proper regen and operating temps.
Avoid excessive idling or very short cold trips.
