Question about 1983 Isuzu Pickup
What is the main problem when there is a low oil pressure when the engine is hot?
I am assuming that the last people to change the oil were probably not the dealer?! If this is true, replace the filter with a AC Delco filter. There IS a difference in filters, pressures and design. If the level is good (?), this should really take care of the issue. Many manufacturers have addressed this issue in dealer TSBs and recognized that the aftermarket quick lube places have failed in quality as well as many aftermarket filter manufacturers.

Replace the low oil pressure indicator sender switch.
If you still get a low oil alarm at idle, there is some other engine problem causing it.
Get the oil pressure checked with an independant gauge before proceeding further.
