None is needed. The car came from VW with hardened valve seats, and by now this specimen has had the heads changed--and all aftermarket heads have unleaded valve seats.
lead
No.
Tetraethyl lead was previously used as an additive in gasoline to improve engine performance. However, due to its harmful effects on the environment and human health, its use has been largely phased out.
Yes, I would add a lead additive.
In the past we used gasoline with a lead additive in it. Since lead is a heavy metal and can cause birth defects, the US government required that gasolines be lead-free.
The abandonment of lead as an anti-knocking additive to gasoline and the discontinued use of lead as an insulator in water pipes, contributed to lower demand beginning in the 1970s.
lead additive to fuel and CFC gases
maybe, should be using a Lead substitute additive to prevent trouble.
A royal blue or lavender tube is typically used for lead blood tests. These tubes contain an additive that helps preserve the stability of lead in the sample during transportation and analysis.
No, lead and tetraethyl lead are not the same. Lead is a chemical element (Pb) found in nature, while tetraethyl lead (TEL) is a compound used as an antiknock additive in automotive gasoline. TEL contains lead as one of its components but is a distinct compound with its own properties.
most all auto parts stores carry a lead additive for this purpose, it is fairly inexpensive and works very well because it is simply a lead additive that the unleaded fuels do not have. it is complete of course with the mixture ratio instructions and they must be followed correctly, if they are not then youwill damage your valve train or valves in the engine.
No, pure lead is rarely used in manufacturing due to its softness and poor mechanical properties. Instead, lead is typically used as an additive in alloys, such as lead-acid batteries or solder, where it improves certain properties like machinability or conductivity.
