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. * Forms a protective and lubricating coating on the valves and valve seats, just like the one built-up by lead in leaded petrol. * Protects the soft valve seats against premature wear when using unleaded petrol (prevents formation of micro welding). * Prevents degradation of the fuel in the tank when the engine is put out of service for several months. * Protects the fuel against oxidation. * Prevents deposit formation in the tank and filter caused by oxidation products. * Eases starting of the engine after a period of extended shutdown. * Is safe for the catalytic converter. * Is completely soluble in petrol. * Does not influence the octane number. * For all two- and four-stroke petrol engines. * For engines of cars, motorcycles, LPG engines, yachts, outboard engines, generator sets, pumps and lawn mowers.

Old engine is in good order because...
3 x Wynns Lead Substitue with Fuel Stabilizer 250ml I have an old vehicle - 1982 - which really doesn't like modern fuel. I've been using this product more than ten years (it actually may be nearer twenty!) and found it to be consistently excellent, and easy to use.I recently had the cylinder head removed to have the tappets checked, and the mechanic was genuinely surprised how good everything looked. I feel I can ascribe this to my conscientious and regular use of this product.Don't leave home without it. Keep one in your vehicle. The top acts as a measuring cylinder, so you won't end up with a smelly mess anywhere!

Fuel additive
It's a fuel additive, you add it fuel and drive your car.
