Lead Substitute

Nulon Lead Substitute (LS) makes unleaded petrol (ULP) safe for use in all vehicles that were designed to operate on leaded petrol (pre-1986 in Australia). LS is also formulated to provide maximum protection for LPG engines when added to under - bonnet lubricator kits.

For use with petrol engines

LS uses the latest and safest potassium technology to provide unsurpassed valve and valve seat protection. Nulon LS can also be used in unleaded vehicles where additional upper cylinder lubrication is required. LS is safe to use in all brands of ULP and PULP (premium unleaded petrol) fuelled engines with cast iron cylinder heads for an indefinite period of time to avoid costly cylinder head modifications. Nulon Lead Substitute has been tested to, and passed, the stringent and demanding requirements of Australian Standard AS4430.1-1996 "Engines designed for leaded petrol to operate on unleaded petrol".

There are numerous products on the market that claim to provide protection that will allow engines designed to run on leaded petrol to run on unleaded petrol. The above Australian Standard is to protect consumers. So, beware of any similar product that has not been tested to, and passed, the requirements of the standard.

For vehicles sold in Australia prior to 1986 there is no fuel available now that will provide valve seat protection for these pre 1986 engines.

For use in LPG fuelled engines

LPG enters the combustion chamber of an engine as a completely dry fuel. As a result it burns very much hotter than does petrol, which enters the combustion chamber as air and very fine droplets of petrol. The petrol droplets provide a cooling affect. The increased operating temperature in the upper cylinder area of an LPG engine is very harsh on valves, valve seats and valve guides.

Nulon LS is ready for use in under-bonnet lubricator kits. If the lubricator kit is adjusted correctly 1 litre of LS should last fro 7,000 to 10,000km.

Nulon LS is cost effective, has been tested and proven to protect valves and valve seats in harsh operating conditions and, more importantly, will be around for a long time to come.  Nulon LS puts the consumer in control of what goes into the fuel system of their beloved old car, or LPG powered engine.
