Back in the late 1950s, I used two synthetic engine lubricants, one was
a clear liquid that was made by Prestone and the other was purple but I
don't remember the manufacturer was. Is todays Royal Purple the same
synthetic oil?
Guess I haven't been paying attention, being a long-time Mobil 1 user.

the engineer who was selling me the motor about motor oils, and I mentioned
Mobil 1 and Castrol Syntec, his only answer was, after testing oils for the
past seven years, he uses Royal Purple.
