<VV> oil change to 15-40

[J. R. Read]

Ken,  Has this engine already been broken in with regular "dead-dino" oil? 
I think you want to get 1,000 miles and about 3 oil changes along the way on 
it before you go full synthetic.

Also, I had not noted the SN rating on the chart for 15-50 Mobil 1 until Jim 
Davis and Bob Helt pointed out the error of my thinking on using nothing 
past SL.  Maybe that only applies to non-synthetic oils?  Or, maybe my 
thinking is just out of date at this point.  Things change and it behooves 
us all to try to stay current on what is correct for our Corvairs.

In other words, I learned something in this recent exchange about oils.

Later, JR
