what oil to use

The Fram story is a myth as well. They may be marginally more expensive on the high end, but their good filters are just as good as the other's good filters and their cheap filters are just as bad as the other's cheap filters.

The Fram myth has been perpetuated basically due to volume. With the lion's share of the market for many years, it was only logical that more filter failures were attributed to Fram than other brands. Once the myth ball gets rolling, it's darn near impossible to stop.
