Valve seat wear
Wynn’s Lead Substitute is a treatment with dual action for petrol engines:
• Protects the valve seats and reduces their wear when using unleaded petrol.
• Preserves the fuel when stored in a tank for a long time, when the engine is put out of service for a long period or at irregular use, e.g. LPG engines, motorbikes, lawn mowers, yachts, outboard engines of pleasure boats, etc.
