Description

Restore and Protect Your Engine

Würth Engine Oil Performance Improve is a hydrocarbon-based additive that enhances the performance and longevity of modern engine oils. Over time, engine oils lose effectiveness due to heat, combustion by-products, and contamination, leading to deposits, sludge, and reduced lubrication. This improver supplements depleted additives and restores optimal oil function.

Comprehensive Engine Protection

  • Sludge Removal: Cleans and removes oil sludge while unblocking critical lubrication ducts.
  • Deposit Control: Loosens and removes resin coatings from piston rings to restore mobility and sealing.
  • Corrosion Resistance: Neutralises aggressive acids produced during combustion, reducing internal wear.
  • Lubrication Improvement: Minimises friction, allowing smoother engine operation and helping reduce wear-related noise.

Versatile Application

This additive is suitable for all petrol and diesel engines, including those running with biofuel blends. By restoring oil stability and protective qualities, it ensures that engines remain efficient and protected between service intervals.
