Volkswagen Passat B5 Discussion
I have 1998, 1.8T AEB. I went to O'Reilly to get some synthetic oil for the oil change. They did not have 5W-40 Passat recommended. So, I got 5W-30 Castrol Edge Synthetic.
Do you think it is ok to use 5W-30 grade oil, rather than 5W-40? What grades can be used to substitute 5W-40...
