First set of questions:
What viscosity oil is being used? Should be 20w-50 or synthetic equal like
15w-50.
What is the fill level? Top mark is too high.
How hot is the engine running? Use infrared thermometer on case. 200-210
max.
What is the idle speed? In gear. 850-900.

Next it is possible to have a bad switch or better yet, the wire is frayed
somewhere and shorting out turning on the light.

Next step is to check the oil pressure with a gauge.

Subject: Flickering Oil Light 84 auto

I have an 84 vanagon, automatic, after it gets good and warm and has been
driven vfor a while I notice at  idle I get a flickering oil light. Oil
level is good, rasing the RPM's ever so slightly makes it go away, as does
putting it in park and letting it idle.
Any ideas?

Thanks,
