Purpose and Specifications

PRO-TEC EF Engine Flush is a powerful 375ml additive designed for thorough cleaning of gasoline and diesel engine oil systems. Add it to your old engine oil before the oil change to safely remove sludge, dirt, and harmful deposits that build up over time, restoring your engine to peak performance without harsh chemicals.

This mid-class product from PRO-TEC excels in practical benefits: it cuts friction and wear on vital parts like pistons and bearings, extends oil drain intervals up to 10,000 km or 12 months, and boosts engine life by neutralizing corrosive acids. Works reliably in operating temperatures from -30°C to 150°C, protecting against rust and overheating for smoother, quieter operation and better fuel efficiency.

• 375ml bottle treats engines up to 6 liters
• Suitable for all gasoline and diesel vehicles
• Shelf life: 3 years unopened

When to Use / Replace?

Use PRO-TEC EF every oil change, especially if your vehicle has over 50,000 km, shows signs of sluggish performance, increased fuel use, or noisy operation. Run the engine for 10-15 minutes with the flush mixed in old oil, then drain and refill with fresh oil for immediate results like reduced emissions and longer catalytic converter life.

Replace flush treatment at every major service (every 10,000 km or 12 months) to maintain cleanliness; no need for more frequent use unless heavy deposits are suspected.
