What Randall said, the concerns about valve recession when they took out of gas does not seem to have turned out to be as bad as some projected. I have run a number of cars for a number of years without hardened valve seats and haven't seen any problems. If it were a daily driver I might be more concerned, but I put couple thousand miles a year or so on my Triumph, will probably have some other major malady befall my car (or me) before I have terminal valve recession.
I run Valvoline VR1 as well, I noticed the straight 50w was on clearance at Advance Auto, hope they are not phasing the line out. Brad Penn is a popular choice too, though a little harder to find, there are others as well as Randall mentioned.
