Engine Treatments: Top-End Treatment

Extended oil drain periods and stop-start driving place high demands on modern oils, leading in some cases to premature wear and excessive valve train noise.

Tec4 Top-End Treatment is a complex blend of lubricity agents, viscosity improvers and oil fortifiers which combine to reduce oil consumption and inhibit engine noise.

Key Benefits:

  • Releases sticking valve stems and hydraulic valve lifters
  • Inhibits engine noise
  • Provides anti-wear protection
  • Improves engine performance and response
  • Reduces excessive oil consumption
  • Compatible with all modern API and ACEA specification engine oils.

Tec4 Top-End Treatment is designed to be used in conjunction with Tec4 Oil System Cleaner.

Add one 400ml bottle of Tec4 Top-End Treatment to the crankcase of a typical motor vehicle following the oil change.

For larger capacity engines the product should be applied at a rate of 10% by volume.
