ISTR that hot idle oil pressure of 20-30psi was normal on the four pot engine
when it was new and running on a 20W/50 mineral oil like Duckhams, Castrol and
Shell.
Only use synthetic in the family Kia and Hyundai through necessity.

make sure the oil pump clearances are correct and on the tight side.
