<VV> Multi-grade oils in Corvairs

[TOM DUDAK]

I have had my share of VW's and always ran 15W40 in the winter and 20W50 in the summer, and very spirited driving, plus flat out highway running and I've never experienced a problem. So with that in mind I now run my Corvair the same 15W40 in the winter and 20W50 during the summer. I was partial to Castrol GTX but have switched to Royal Purple and have been pleased so far.
