: Hi Damien,

: With the number of cars that require Lead Replacement Petrol (LRP) decreasing,
: Shell is progressively reducing its distribution of LRP throughout Australia.

: Most cars that use LRP were built before 1986 and have valves in their engines
: which require protection from valve seat recession.

: Valve seat recession is the wearing down of the exhaust valve closing surfaces
: in the engine by abrasion and corrosion. Excessive wear can result in the loss
: of compression, power, fuel efficiency and engine performance.

: With leaded petrol, lead protected valve seats against wear. LRP was introduced in its place in 2000 to offer the same protection as leaded petrol without the health and safety concerns. LRP combines a specially formulated 96 octane rating unleaded petrol with a non-lead additive which protects against valve seat recession.

: Who will be affected?

: Only cars that currently require LRP to protect against valve-seat recession.
: Typically these vehicles are manufactured before 1986 and require the addition of an anti-valve seat recession (AVSR) additive to every fill of premium unleaded petrol to ensure valve seat protection.

: Some pre-1986 cars can use regular unleaded. Other's do not require AVSRs but still require a higher octane fuel such as Shell Optimax.

: A list of pre-1986 cars that can run on unleaded petrol without AVSR protection is available on the Australian Institute of Petroleum's website, alternatively contact your vehicle manufacturer.

: The Solution

: 1. Shell Optimax or Shell Premium Unleaded Petrol

: Shell recommends LRP users switch to Shell Optimax or Shell Premium Unleaded petrol and where necessary use an anti-valve seat recession additive.

: The cleansing properties of Shell Optimax premium unleaded petrol care for a car's engine regardless of age, making it ideal for current LRP users.

: Built up carbon deposits on inlet valves are removed and fuel injector, or carburettor systems are also kept clean and in top condition. This leads to consistently good fuel/air mixture preparation, better combustion and driveability and improved performance.

: 2. AVSR Additive

: AVSR additives act as a solid lubricant between the exhaust valve and the soft exhaust valve seat, preventing the valve from recessing into the cylinder head.

: AVSRs, such as the Valvemaster range, are added at the pump when refueling to add the extra protection leaded cars need to prevent valve burning and loss of engine performance due to reduced engine compression and possibly engine failure.

: AVSRs are available in the shops of most Shell and Coles Express stations.
: AVSRs are added directly into the fuel tank but it is important to read the instructions before use to ensure you are using the right product and the right amount. Use of incorrect amounts of AVSRs could damage your engine.

: Also, please find attached a brochure issued by the Australian Institute of Petroleum with more information about the phasing out of Lead Replacement Petrol.

: I hope this information assists.

: Kind regards,

: Fellow Travellers;

: In the next issue of 'leylines' there is an article on using ULP in the six and 8 cylinder P76's.

: Ask your club editors for a look at the article when it is sent to them.

: Or you can go to the p76act yahoo group and read it there.

: Ive attached below a response from Shell to a question I asked them on the phase out of LRP, which is a related issue.
