Oil Light comes on ((and freaks me out))

[JeffnDes1977]

1977 Bus 2.0FI - Lately my oil light has been coming on randomly and I don't care for it. It usually happens after it warms up and I head out to work. About a mile down the road, it comes on at the second stop I make. Then its usually normal the rest of the drive. I took it in to my local aircooled VW service shop and they checked the oil pressure and its fine. I have an engine saver dipstick and I feel like I never saw the oil light on until I started using that dipstick, other than on start-up.

A couple notes

I've owned this bus since 2007 and have been driving it at least once a week for the last few months - the most its moved since I got it. It sat off and on for several years previously.

I have a print of the oil pressure numbers at home, but not in front of me at this moment.


Any info helps

Do the 2L engines have a pressure relief valve like the 1600s? Maybe it's sticking from a burr or debris?

Unhook it from the dipstick and see if that stops the light from coming one.

Another solution looking for a problem, those dipsticks…

I'm going to assume that 'second stop' is at a downhill slope/grade & the oil is pooling near the 1/3 cylinders. Just some air. Happens.

As long as it goes out on light revolutions, ignore it, just like the manual says.

The "save my bug" dipstick starts the oil light blinking if you put it in a bus, and get the bus properly warmed up, not even hot for a bus.

Because a bus runs hotter than a bug.

At least on a Type 1 it’s not in the cooling airflow inlet AND passing through the fan shroud.

Heat soak city.

Sales of the dipstick rocketed after the Dukes ofHazzard aired….

I used to figure that any add-ons being sold for VW's by JC Whitney were very apt to be bogus, while today this same business has been taken over by others like CIP. Glad that when I first got into VWs, the recommended oil for that car was a straight 30wt for warm season use with a note about not using multi-grades, which was the same advice given in a class on lubrication that I had taken, which was taught by a former EXXON lubrication engineer who had helped develop EXXON's late 1960's multigrades. I figure that advice helped save me from ever going down the VW engine oil rabbit hole that so many still willfully crawl into.
