Are you the proud owner of a classic car, bike or boat? Or maybe you’ve got an old Atco or similar classic lawn mower tucked away? Well, if you do, then you’ll be aware of the importance of lead replacement additives. Basically, lots of old engines fitted with soft exhaust valve seats will require lead in the petrol – This lubricates and protects from recession, which is an integral part of keeping a classic engine in top performance. At Opies, we stock a product that is designed from the ground up as a top quality petrol lead replacement additive that is easy to use and gives guaranteed protection – Motul Valve Expert.
