Purpose and Specifications

PRO-TEC HLC is a powerful engine oil additive designed for cleaning hydraulic lifters and the entire oil system in both diesel and gasoline engines. This German-made formula, in a convenient 375ml bottle, effectively removes sludge, varnish, and contaminants that cause noisy lifters and reduced performance, restoring smooth operation.

Add it to your engine oil for practical benefits like quieter hydraulic lifters, better fuel efficiency, and longer engine life. Use at a 1:15 ratio - 375ml treats up to 5 liters of oil - ideal for routine maintenance every 10,000 km or 12 months to keep your engine running clean and strong from -30°C to 150°C operating temps. Shelf life is 3 years unopened.

When to Use / Replace?

• Use PRO-TEC HLC when you hear ticking or tapping from hydraulic lifters, especially in older engines over 100,000 km.
• Perfect before oil changes to flush out buildup, improving compression and reducing wear.
• Replace or reapply every oil change (typically 10,000-15,000 km or 12 months) for ongoing protection against acid corrosion and friction.

FAQ

Is PRO-TEC HLC safe for all engines? Yes, it's compatible with gasoline and diesel 4-stroke engines, transmissions, and differentials when mixed with any standard motor oil.

How soon do I see results after adding it? Lifters quiet down within minutes to hours as the engine runs, with full cleaning benefits after 100-200 km of driving.

Can I use it in high-mileage vehicles? Absolutely, it's best for engines over 100,000 km to stop leaks, reduce wear, and extend life without changing oil viscosity.
