★ Essential protection for classic engines developed for leaded petrol. Prevents costly engine damage to valves and valve seats.
Application
For use in petrol engines built before the mid-1970s, originally designed for leaded petrol and not fitted with hardened valve seats. Not required for engines with already fitted hardened steel valve seats.
Installation notes
Add to fuel tank before refuelling. Mixing ratio: 1 ml additive per 1 litre of petrol. During intensive use (high revs, heavy load) increased dosage may be applied. Use at every refuelling for continuous protection.
Compatibility
Suitable for all older petrol engines with soft (non-hardened) valve seats. For engines fitted with hardened steel valve seats during overhaul, lead substitute is no longer necessary. Not harmful to catalytic converters.
Historical context
Lead was added to petrol from the 1920s onwards to increase octane rating and protect valve seats. After the ban on leaded petrol in the 1990s, lead substitutes were developed to enable continued use of classic engines without costly cylinder head overhaul.
