Engine additives play a vital role in reducing wear within internal combustion engines

Continuous mechanical contact between pistons, bearings, and valves gradually erodes metal surfaces unless properly lubricated

They work by chemically bonding to surfaces, forming a shield that reduces direct metal-to-metal contact under extreme conditions

Zinc-based antiwear compounds are among the most widely employed solutions

These chemicals, such as zinc dialkyldithiophosphate or ZDDP, react with metal surfaces under high pressure and temperature to form a thin, durable film

This film acts as a barrier between metal components, preventing direct contact and اتوسرویس داوود minimizing the abrasive effects of friction

High-revving race engines and turbocharged units demand these films to withstand extreme thermal and mechanical stress

Another category of additives includes friction modifiers

By smoothing the interaction between cylinder walls and rings, they reduce parasitic losses

This results in less thermal stress and slower degradation of bearings, pistons, and valve guides

Detergents and dispersants also contribute indirectly to wear reduction

By keeping engine internals clean, they prevent the buildup of sludge and carbon deposits that can act as abrasive particles

Clean oil flows freely, reducing particle-induced erosion

Many aftermarket products exaggerate benefits without third-party validation

Independent lab tests often reveal negligible or even detrimental effects

Choosing additives that meet industry standards, such as those certified by the American Petroleum Institute or OEM specifications, ensures compatibility and effectiveness

Overuse or incorrect application can lead to negative consequences, including clogged filters or damage to emissions systems

Regular oil changes with high quality base oil and properly formulated additives remain the best defense against engine wear

Skipping service intervals negates even the best additive benefits

Properly treated engines often exceed 250,000 miles with minimal wear

For vehicle owners seeking long term reliability, understanding and using the right additives is a smart investment
