[Fot] isky oil recommendations

[Mike Harmuth]

I used VR-1 oil as well and during the last rebuild, the bearings could
have been reused (didn't). The cam (journal end, not the lobes) did have
wear, but I think it came from a soft, "new chilled" blank, not the oil.
Here's a nice chart from Speedway motors with zinc by brand, even ones they
don't sell. VR-1 is good, just not the highest concentration on the list.
