Yikes that looks terrible! Already wavy after only 50 miles
What did you replace it with?
I replaced it with a Wix XP (which has the correct bypass setting) and filled it with Castrol Edge EP 0W-20. Over 75% of the 5,000 miles I've put on it have been EV only. The range extender is really only used for long highway trips, so it'll probably be following the two year OCI by the book.
