Not all premium gasoline needed lead (TEL) to increase anti knock rating. Some refiners offered high octane unleaded gas AND Kiedhaefer recommended
it when available back ing the days of Green Tank Mercs. Kiekhaefer also offered a premium 2 cycle oil well before TCW-3.
There was a lot said about need for lead to avoild damage
to valve seats when nonlead
was mandated. Not a word about
problems with the unleaded premium that had long been on
the market by a major refinery. Then again, cars in the 1950s were made to last
until the 36th payment was mailed.
