Just had oil changed in 1986 VW cabriolet. They used 5w30 and after driving about 20 miles the battery and oxs light came on and will not go off. Why would this be? No manual. Is 5w30 wrong oil?

Possibly different issue. I would check battery connection and output voltage of the alternator. It should be around 14.5 volts
