  Te 10W-30 is more of a problem than the brand of oil filter. It is
  common for the oil to get hot and the oil pressure to drop when the
  engine is operated at high speeds for long time periods. When used in
  this fashion, 20w-50 or synthetic equivalents are the only way to go.

I agree that 10-30 is marginal, unless you are constantly driving in very
cold temperatures.  My solution for a climate that seldom gets below 0 F but
can be over 100 F in the summer is to run 20-50 in the warm months, and
15-40 in the winter.

It's not going to thin out as much as 10-30, but it enough thinner than
20-50 when cold to make it easier to start the engine.
