I just changed oil in my Vanagon, (1.9 engine) and even after running for several minutes, the oil pressure light won't go off. Also, I have not used the van much lately, but when I do the gas mileage is really bad!(1/3 or 1/2 of normal) Can the gas mix with the oil in any way if something blew? It smokes some, but not horribly. Seems really low on power though. Don't know where to start. Thanks for your help.

To start, it sounds like the oil pressure switch needs replacing. That should turn off your oil light. Assuming you have sufficiant oil and all is well.
But you know what? Not to alarm you,but I would take it to a local shop and have them do a compression check on the motor. Because what you are describing does not sound good. This is worst case. If it has miles on it,and the compression is low in the cyliders...time for a motor exchange.

You said gas but I've only heard of diesel 1.9L engines. Sorry I haven't memorized all of the VW engines available. So if it is a diesel then here is a guess.
If you did not use 15w40 oil then your seal for your cylinders will be bad, lowering you compression, lowering your fuel efficiency, lowering your power, lowering your oil presser.
So make sure to use the correct oil for the weather.
Also the oil pressure unit in the dash panel (the thing that beeps) is very common for VW's to go bad and will normally start beeping after 2000rpm when it looks for the signal from the High Oil Pressure switch on the side of the engine head. The sensors are also common for malfunctioning and are cheep to fix if they are found to be bad but the dash panel is about $400 Canadian dollars for the part alone.
There are also a lot of complaints about engine sludge with VW's but I believe that problem to be people switching the type of oil they use often because they got a better deal on different oils and having the different additives make the sludge when they mix.
(but none of this Idea is for sure). Just another thing to be aware of.

I would take the car into the dealership or another automotive repair expert. I suspect that you have an oil leak. You should check under your car for oil spilling onto the ground which is a tell-tale sign that there is an oil leak. Good luck.

ok so how did your gasket replace and oil replace? have them verify to work out if the positioned your oil sending unit wires back on all the way? if that isn't the topic then do away with the detrimental battery cord then replace it back and see if that resets the oil stress gauge.

There is a reset switch that needs to activated, a shop secret...
