on the bottom of the oil pan

Subaru's have an opening in the plastic splash pan below the drain plug. If you look you will see it.

If you can't find the drain plug, do us a favor and DO NOT change oil yourself.

I agree with Bob as changing the oil yourself may void the warranty as it is not documented.

Changing your own oil will not void the warranty. Just keep a record of it and receipts and use the proper viscosity and quantity. Changing it and messing it up is another thing. If you can't find the drain plug it is probably best not to change your own oil.

The question quality here just keeps going down and down.

Whatever you do, avoid 0w20 oil in the summer.

What do you think about installing a Fumoto valve at the first oil change?

Why? I see them once in awhile, but don't think there's any advantage to them. And if one blows, you've got an expensive mess, eh?

A magnetic plug is a better choice.
