Long Life Oil System Cleaner

Tec4 Long Life Oil System Cleaner is a high-performance oil additive designed to provide continuous engine cleaning and long-term protection of engine oil. The product combines the cleaning power of an engine cleaner with an advanced additive package that actively enhances oil performance.

By using viscosity improvers, premium lubricants and surface-active agents, the engine remains clean between oil changes while wear and contamination are effectively reduced.

Unlike traditional engine flushes, Tec4 Long Life Oil System Cleaner is added directly to fresh engine oil, immediately after an oil change or during extended service intervals.

Key Benefits

  • Keeps the engine clean between oil changes

  • Improves engine oil performance and stability

  • Dissolves contaminants and keeps them safely in suspension

  • Protects wet timing belts

  • Reduces the risk of Low Speed Pre-Ignition (LSPI)

  • Extends engine and oil service life

  • Suitable for petrol and diesel engines

How It Works

Tec4 Long Life Oil System Cleaner continuously cleans the entire oil system during normal engine operation. Contaminants are dissolved and held in suspension, preventing deposits from forming. During the next oil change, these contaminants are completely removed with the drained oil.

This makes the product ideal for preventive service and for engines operating with extended oil change intervals.

Directions for Use

Tec4 Long Life Oil System Cleaner can be added at any stage of the engine’s service life.

For best results:

  1. Pre-clean the engine using Tec4 Oil System Cleaner

  2. Change the engine oil

  3. Add 1 bottle of Tec4 Long Life Oil System Cleaner to the fresh engine oil
