Purpose of Oil Additives

Oil additives serve an important purpose in modern engines by providing extra protection and performance. Liqui Moly uses a range of specially formulated additives to enhance the properties of its motor oils.

Some key types of additives found in Liqui Moly motor oils include:

• Detergents - Help keep engine internals clean by preventing deposit build-up. Detergents disperse oil sludge and residues so they can be drained out.

• Dispersants - Also help suspend contaminants in the oil to be drained out. They prevent sludge from coagulating.

• Anti-wear additives - Form protective layers on metal surfaces to reduce friction and wear. Important for protecting camshafts, pistons, bearings.

• Rust and corrosion inhibitors - Protect engine parts from corrosion damage from moisture, acids.

• Antioxidants - Help prevent oil from oxidizing and breaking down prematurely. Maintain oil's viscosity and lubricity.

• Friction modifiers - Lower friction on certain surfaces. Can provide fuel economy benefits.

• Pour point depressants - Allow oil to flow more easily at lower temperatures.

The right additive package allows Liqui Moly oils to better resist breakdown while protecting critical engine components.

Specific Oil Needs for Motorcycles

Motorcycles have different lubrication needs compared to cars and trucks. Here are some key considerations for motorcycle oil:

• Motorcycle engines tend to run hotter and at higher RPMs than car engines. This puts more stress on the oil, requiring formulations that resist viscosity breakdown and provide excellent wear protection. Liqui Moly motorcycle oils use high quality base stocks and additives to meet these demands.

• Motorcycles tend to have separate engine, transmission, and primary case oils. Each component requires oil meeting specific friction and viscosity properties. Liqui Moly offers oils tailored for each motorcycle fluid reservoir.

• Wet clutch systems are common on motorcycles. These clutch systems bathe the clutch plates in engine oil, requiring specialized friction reducing additives. Liqui Moly oils for wet clutch bikes provide smooth clutch engagement without slippage.

• Air-cooled motorcycles lack radiator-based cooling systems. This increases the importance of oil helping to dissipate heat. Liqui Moly motorcycle oils feature thermally stable formulations to maintain protection in air-cooled bikes.

• Motorcycle engines produce more contaminants from blow-by gases and combustion soot. Liqui Moly oils use shear-stable polymers to keep soot dispersed and provide extended drain intervals.

With their expertise and experience in powersports lubrication, Liqui Moly offers a full range of motorcycle oils meeting the unique needs of bike engines and transmissions. Riders can trust Liqui Moly to provide outstanding protection, performance, and peace of mind.

Unique needs for diesel engine oil

Diesel engines have different needs compared to petrol engines when it comes to engine oil. This is due to fundamental differences in how diesel and petrol engines work.

Some key considerations for diesel engine oil include:

• Higher operating temperatures - Diesel engines tend to run hotter than petrol engines, putting more thermal stress on the oil. Diesel specific motor oils are designed to withstand higher heat.

• Contamination resistance - The injection process in diesel engines can cause more soot and deposits to form in the oil. Oils for diesel need to be robust against this contamination.

• Shear stability - Diesel oil needs to maintain its viscosity grade for longer in order to cope with the demands of a diesel motor. Special viscosity improvers help with shear stability.

• Detergent/dispersant additives - More detergents are needed to keep diesel engines clean and disperse soot in the oil. This prevents thickening of the oil over time.

Liqui Moly offers a range of diesel specific motor oils designed for both passenger car and commercial vehicle diesel engines. Key products include:

• Top Tec 4100 5W-30 - Fully synthetic low ash oil for diesel particulate filters. Keeps DPFs clean.

• Top Tec 4200 5W-30 - Minimizes wear and oil thickening in Euro 6 diesel engines.

• Top Tec 4600 5W-30 - For modern diesel engines with exhaust after treatment. Excellent protection against soot.

So in summary, Liqui Moly diesel oils are formulated to withstand the unique demands of diesel engines compared to petrol engines. This includes higher heat resistance, soot handling, shear stability, and detergency.

Considerations for classic car oil

Classic and vintage cars have different lubrication needs compared to modern vehicles. Using the wrong oil can lead to increased wear, sludge build-up, and engine damage over time. Liqui Moly offers a range of oils specifically formulated for classic and older engines.

When selecting oil for a classic car, it's important to consider the operating conditions and design of the engine. Most vintage engines are lower compression and run at lower temperatures compared to modern engines. The oil needs to flow well when cold but also maintain film strength at operating temperature.

Many older engines also have wider bearing clearances so the oil needs to maintain adequate pressure. Using a multi-grade oil helps provide protection across a wide temperature range.

Detergent and dispersant additives found in modern oils can be too harsh for some older engines as well, leading to seal deterioration and leaks over time. Liqui Moly classic oils use milder additive packages to prevent this.

Zinc levels are also important for protecting vintage engine components but need to be balanced to avoid damaging catalytic converters in collector cars. Liqui Moly oils are carefully formulated with optimal zinc for older flat tappet cams while remaining emissions compliant.

With the right oil matched to your specific classic or vintage engine, you can keep it running smoothly for many more miles down the road. Liqui Moly's range provides excellent lubrication and protection tailored for older design needs.

Recommended Oil Change Intervals

Liqui Moly provides guidance on recommended oil change intervals for a variety of vehicles. Intervals can range from 5,000 miles/8,000km to 10,000 miles/16,000km or more, depending on the vehicle make, model, year, and engine.

Some key factors that determine optimal oil change intervals include:

• Vehicle age and mileage - Older vehicles and high-mileage engines require more frequent oil changes. Newer vehicles can often go longer between changes.

• Driving conditions - Vehicles used for towing, hauling heavy loads, extensive idling, or short trips require more frequent oil changes. Cars driven primarily on the highway in ideal conditions can have longer intervals.

• Climate and weather - Extreme hot or cold temperatures, and dusty conditions cause oil to break down faster. More frequent changes are recommended.

• Engine type - Turbocharged, supercharged, and high-performance engines need oil changes more often to preserve engine life.

Liqui Moly oils are formulated for extended performance and protection, so relying on their guidance for oil change intervals can help optimize engine life. Consult your owner's manual, however, for the intervals recommended specifically for your vehicle.

Importance of Oil Filters

Oil filters play a crucial role in engine health and performance. They help remove contaminants and particles from the oil to keep it clean. Over time, engine oil picks up metal shavings, dust, dirt and carbon deposits which can damage internal components if left to circulate.

Oil filters use a combination of filter media to trap and hold these impurities. As oil passes through, contaminants are captured while clean oil flows back into the engine. The filtration process extends the life of oil while protecting precision parts from unnecessary wear.

Regular oil and filter changes are key to reducing friction, preventing sludge build-up and maintaining proper oil pressure. Quality filters with efficient flow rates ensure full oil circulation for cooling and lubrication. Premium brands like Liqui Moly utilize advanced designs and materials to provide superior filtration. Their oil filters can withstand high temperatures and pressures while trapping more contaminants between changes.

Proper oil filter selection depends on the vehicle make and model. Using the manufacturer's recommended filter ensures optimal fit, flow rate and filtration for the engine. Liqui Moly offers a full range of OE replacement filters meeting strict specifications for many European vehicles. Their filters provide trusted protection recommended by mechanics.
