Just changed my oil at 1500 miles.
Used the 4.4 quarts and it fills it to about 1/8th inch or 3 mm below the full mark.

 

How did you get under it to change the oil and what covers did you have to remove?

 

There's a single smallish cover just for oil plug/filter access on the passenger side, just forward of the front wheels. You can see it in the image below. It's part of a much larger cover.

The front jack point is not fun to get to. If I was doing it, I'd probably use ramps and chocks for something quick. For something longer where I'd want more room and safety, I'd use ramps to get better access to the jack point, then use a floor jack to lift the front enough to get jack stands underneath.


a. jack points
b. support points
c. center of gravity (unloaded)

 

Yeah once again it looks like the front jacking point is waaaay back.

 

How long is your arm? I've been able to just reach the drain and filter with my cars. Driving the front wheels up onto a 2x6 piece provided enough clearance for the catch can, and to work.
