Mazda cx-7

My husband is trying to change the oil in a Mazda cx-7 but we cannot find a diagram to locate the oil filter. Can anyone help?

from another forum:
“on the passenger side towards the back, if you look from the top of the engine you can see it. Best view is from under the car.”

Is there anywhere to get a diagram? We are thinking that there may be a panel that needs to be removed to change the filter. Is that true?

I got the quote above from an quick internet search. The implication is that there is no panel. A more extensive search may get more info. But, just take a look behind the engine as described (between the engine and the passenger compartment), it should be barely visible. It looks, apparently, like an oil filter.
