Note that it says 30-35 for cruising. I have a Continental manual in
my lap and it specifies 30-40 for cruise. 30 is fine though towards 40

revs and you're not running sewing machine oil, you don't have enough
to keep from scraping bits of metal together on your cam or your
bottom end.

OK, well if your pressure is good at the high end, it's probably not the
relief valve. Any adjustment or replacement I've ever seen on that usually
changed it right across the board. In fact, if it's OK at the high side and
you replace it or put some washers in or whatever, you'll probably find it
going over the top on the high side and staying there. OTOH, it costs
nothing but a bit of time to try it.
