Motor oil enhancers are essential for protecting engine components from friction-induced damage

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

Other effective formulations include molybdenum and phosphorus-based chemistries

Under extreme load and heat, ZDDP decomposes to create a sacrificial phosphate-glass layer that coats metal

It effectively decouples high-pressure contact points, reducing wear rates by up to 70% in demanding applications

Vintage engines with flat-tappet camshafts still rely heavily on ZDDP for survival

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

These cleaners maintain internal engine cleanliness by suspending contaminants

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

When these contaminants are suspended in the oil and filtered out, they are less likely to grind against surfaces and cause accelerated wear

Many aftermarket products exaggerate benefits without third-party validation

Independent lab tests often reveal negligible or even detrimental effects

API SN, SP, or Ck-4 ratings are reliable indicators of quality

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

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

They enhance protection but cannot compensate for neglected oil changes

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

Informed choices prevent costly rebuilds and preserve resale value
