I used 20-50W engine oil to my VW 2009 1800cc Gol and I put more than 4 lit , two times sensor of the engine got out of order ,does it have any thing to do with the engine oil or is it something else?
20W50 is too heavy engine oil. The book shows 5W30 is recommended. Why did you go so heavy?
I live in a small town, I can't find it easy. the nearest shop having such oil is 20 km away.
