<VV> Multi-Grade 10W-40 Motor Oil in Corvairs ?

[Bryan Blackwell]

IMHO, you absolutely should.  The thing to be concerned about these  
days is the ZDDP content, look for something that explicitly says  
"Recommended for flat tappet applications".  If it doesn't, don't use  
it.  Remember that "high mileage" cars these days are still only 10  
years old and have roller lifters, they aren't talking about Corvairs,  
or anything else built before 1990.

Threads in the VV archives and lots of other classic/antique car  
sites, but that's what it boils down to.  Based on the above, seasonal  
usage (no really cold weather) and local availability, I've selected  
Mobil 1 15W-50 for the Corvairs.
