RE: Low oil pressure?

The 15W40 in Canada can be found under the Castrol GTX brand name and
probably others.  I find that 20W50 is just too heavy, even here in 'The
Great White North' our summers are often pushing 85/90 very humid degrees
(F).  I'm running 10W30 currently because I'm about to do my fifth oil
change in two months.  I found it to be the best way to clean the crud out
of the engine and eliminate lifter noise. 20W50 just seems to cause to much
drag on the engine - performance reducer?

Having no recent experience with diesel engines I do seem to recall that
there are different additives/detergents used than in the gasoline engines
and they are not compatible.
