Bravo! Thank you for taking the time to take the pictures and write the description. The location of the drain plug behind the trap door is great info.
Couple questions for ya:
1. Did you measure the new oil, or just try to get close, then check the electronic gauge and adjust, or what? Guess I'm and old fogey and miss having a dip stick, which has been a wholly reliable device on every car I've owned.
2. What about pre-filling into the filter compartment - is it possible? I'd always dumped a-third-of-a-quart into a canister style filter before fitment
