My girlfriend told me recently that she rarely changes her oil on her 2001 VW Beetle 2.0 engine. She also told me that last time she just added oil until it was full. I pulled the dipstick today and the oil was black, gritty and thick!
I am having trouble figuring out which oil weight to put in and whether I can put synthetic in or not. My google searches have come back fruitless since every result i get is the turbo engine
