Went to Mobile and got it changed there,,, last week.. in a 2019 VW Beetle convertible. The manual says to use 508 oil,, asked them about this,, they ''did not know''. However,, I did let them change it,, they said,, ''we use the same oil as a Jetta'' and a few more--- it doesn't look green at all-- neither did what came in when new. In the meantime, I have bought 6 quarts of VW 508/509 oil, plus an extractor, so I CAN swap it out-- if needed. I really don't know whether to or not,, what do y'all think? I really wonder about NOT using the 508 oil, what might happen to the motor? Will the motor blow up? Got any thoughts on this?
