Mannol 9202 Catalytic Ester Petroleum Fuel Additive 450 ml is a premium engine cleaner crafted in Germany to restore fuel system and exhaust performance in petrol and hybrid vehicles. This synthetic ester based complex detergent and lubricant cleans injectors, intake valves, spark plugs and catalytic converter cells without the need for dismantling. It optimizes combustion efficiency, enhances catalytic converter lifespan, improves oxygen sensor sensitivity and lowers carbon monoxide emissions. The advanced formula combats soot, varnish and resin build up while forming a protective oil film that prevents future buildup. Suitable for all petrol engines including two stroke and hybrid models. Add one bottle to 30 L of fuel for deep cleaning or one per 45 L for maintenance. Ideal for city driving this additive delivers smoother engine operation improved acceleration and reduced fuel consumption.

Mannol 9929 Ester Engine Oil Additive 500 ml is a German engineered formula that provides advanced engine protection and performance. Powered by synthetic ester technology this additive magnetically binds to metal surfaces forming a strong protective oil film. The result is reduced friction and wear improved load tolerance and extended engine life. It enhances oil stability decreasing evaporation and boosting thermal resistance which supports longer oil change intervals. In low temperatures it improves cold start performance and lubricity. Ester molecules also clean and disperse deposits while rejuvenating worn seals to help prevent leaks. Compatible with all engine oils and suitable for petrol and diesel engines two stroke and four stroke this additive delivers smoother engine operation better fuel efficiency and reliable protection. Add 500 ml per 5 L of oil regularly to maintain optimal engine health and performance.

Mannol 9954 Octane Plus Additive 450 ml is a high performance octane booster and fuel system cleaner for petrol engines. It raises octane number by 3 to 6 units depending on base fuel while protecting against knocking and engine detonation. The premium detergent formulation cleans injectors intake valves combustion chambers and spark plug tips to restore smooth idling sharp throttle response and optimal fuel economy. It adds lubricity to fuel pump and injector components which helps reduce wear and extends component life. Compatible with all petrol fuel grades including ethanol blends and safe for catalytic converters. Add one 450 ml bottle per 45 L tank for regular maintenance. Mannol 9954 supports cleaner combustion reduced engine noise and improved engine performance.

Mannol 9955 Cetane Plus is a premium diesel fuel additive engineered in Germany to boost cetane number by 2–5 units and enhance engine performance. This advanced formulation cleans fuel injectors, combustion chamber, valves, pistons and diesel particulate filters, effectively removing soot, varnish, carbon and ash. By promoting more complete combustion this additive increases engine power, smooths idling, reduces noise and vibration, and improves cold start reliability. It also protects injectors and high pressure pumps against wear and corrosion while lowering fuel consumption and exhaust emissions. Compatible with all diesel fuels and engines including turbocharged systems, exhaust aftertreatment systems and biodiesel blends, Mannol 9955 is designed for regular use. Simply pour one 450 ml bottle into a full tank (approx 135 L) to maintain optimal fuel system health and enhance diesel engine efficiency.

Mannol 9968 gear oil leak stop is a premium additive for manual transmissions transfer cases differentials and mechanical gearboxes. It uses ester technology to revive rubber and plastic seals restoring shape elasticity and preventing leaks. This formula works at operating temperature and can be used in any mechanical transmission oil offering protection under demanding conditions. One bottle treats 4 to 5 liters of transmission oil and for severe leaks two bottles are recommended. Safe for any gear oil type but not suitable for automatic transmissions. Regular use at each oil change helps slow seal aging maintain seal integrity and extend transmission service life. Ideal for fleet vehicles commercial use or daily driving seeking reliable transmission performance.

Mannol 9981 Gasoline Fuel Injection System Cleaner 300ml is a premium fuel additive designed for petrol engines to boost injector performance and combustion efficiency. This high-quality cleaner rapidly removes carbon, tar and scale buildup from fuel injectors, intake valves and combustion chambers. By eliminating deposits it restores smooth idling, improves acceleration response and reduces engine misfires. The formula enhances fuel atomization which leads to sharper throttle response and lower fuel consumption. Fully compatible with all petrol engines including turbocharged systems and catalytic converters this cleaner is perfect for preventive maintenance and performance restoration. Add one 300ml bottle to a full tank before refuelling to keep your engine running at peak condition. Mannol 9981 ensures reliable fuel system performance and supports long engine life with every use.
