Sorry for synonyms in title, for easier searching.
Also sorry for new thread, I tried searching to find it, but I only found one on the Outback forum.

Like this outback owner, my 2018 Forester XT has a popping/knocking sound coming from (what I believe) is the left power rear gate motor.
It's not as bad as the following video,

First post, so not allowed to post links yet.

As well, I went to the Subaru dealer for an oil change. Instead of putting in the Subaru Synthetic Motor Oil SAE 5W-30 (gold bottle and blue label), they put in Mobil1 synthetic (silver bottle)
Is there a major difference between the two? There does not seem to be consensus on differences of OEM vs third party motor oil. Is the Subaru synthetic still made of mineral oil and not 'truly' synthetic? Not sure about this point, hope someone could clear it up definitively.

I wanted to know if the power liftgate issue is covered by the base warranty or the extended mileage warranty, as I have both on this vehicle.
I'm pulling up my Subaru Protection plan, and the fine print basically says we don't cover "squeaks and rattles" and they won't fix things unless there is a "Breakdown", which essentially means it could be up to their interpretation. Do you think its worth a shot to bring it in to get it fixed under warranty? The worst is I'll leave without fixing it.
