Dick,
What: Valvoline - VR1 Racing 20/50
Why: it is 20/50, it is formulated for high temp/prolonged stress, AND it has
higher levels of Zinc/ZDDP additives that were present in the period oils but
are absent/reduced in modern oils as they trash catalytic converters. A
threshold level of ZDDP is needed in older design/metalurgy engines that have
flat cam followers et al - as Healey engines have.
