My dad gave me a 2008 Scion xB.
Hello everyone, I hope you're having a good day. I had a question. My dad recently decided to buy a 2008 Scion xB with 234,000 miles on it; I don't have the car in my possession yet. My question is: should I stick with 5W-20, or should I opt for 5W-30? The car doesn't smoke, though it did have a "check engine" light triggered by an oxygen sensor in the catalytic converters. What approach should I take? Also, I’d like to know if I can use my VIN to check if the car was part of the ZE7 service campaign, but I don't have access to the "My Toyota Owner" portal since I don't live in the United States.
I want to use 5w20 valvoline Maxlife
