A general question about my grandfather 86 Dodge Caravan...
When you first start it up the Oil Pressure Guage (its a basic analog dial
like the speedometer, engine temp and such) goes up to 3/4 mark between High
and Low pressure.
After driving it for 5 miles or so, it slowly floats down to half way
between High and Low pressure.
After that if the speed drops below 20 or 30mph it settles down to 1/4
between High and Low pressure. It tends to stay there as long as the speed
stays below 30 (I notice it when I'm stuck behind a snowplow for a long
distance) but it goes back up to half way once I get back up to 50mph+
I check the oil levels every so often just to make sure and it hasn't moved
nor are there any leaks. Am I worrying for nothing or should get a mechanic
to check it out?
Its fine other than this, and everything else runs and drives nicely. Is it
something to worry about or should the pressure guage move like this in all
thanks for any advice!
