You hear that being said many places, but I think it is just old
superstition. There is nothing in the Lucas manual to suggest that lead
is required.
A friend of mine with a TR6 wrote to an oil company asking about this, and
got an answer in writing that the unleaded fuel would not harm his pump.
Which should mean they were serious - they would risk liability claims if
harm was caused.
The tetraethyl lead could only have a lubricating effect at elevated
temperatures (as found on the exhaust valve), they said. Which makes
sense to me. I have been driving my 2.5 PI on unleaded for a few years,
and have not had any problems. FWIW.
