Purpose and Specifications

Wynn's 76844 Hydraulic Valve Lifter Concentrate is a premium 325ml oil additive that cleans and lubricates hydraulic valve lifters in petrol and diesel engines, including turbocharged ones. It releases sticking valve stems, dissolves dirt, gum, and varnish in oil channels, and quiets noisy valve train for smoother engine operation.

Key benefits:

• Restores efficient lifter performance without adjustments
• Reduces engine noise and improves power
• Protects against wear with EP agents
• Safe for catalytic converters and wet timing belts
• Compatible with all mineral, synthetic, and low SAPS oils

One 325ml bottle treats 3-6 liters of engine oil. Add directly to the oil sump; it stays effective until your next oil change. Use every 6 months or 10,000 km for best results. Shelf life is typically 3-5 years when stored cool and dry.

When to Use / Replace?

Use Wynn's 76844 when you hear ticking or tapping from the valve train, especially in engines over 100,000 km or after cold starts. Ideal for daily drivers operating in -20°C to 120°C temps. Replace at next oil change or every 6 months/10,000 km to prevent buildup.
