One of the better, 'on the shelf', affordable oils out there.

Our engine oil Ford WSS spec calls for a 5W-20, but many (most??) of us are using a 5W-30 weight oil most of the year, if not year round, as long as we live south of the Arctic Circle.

^^^ALL of the 'on the shelf at Wal Mart', labeled as 'fully synthetic' (even though technically they are not) are really good products.

Many on here (and elsewhere) seem to think that Pennzoil Platinum Plus (even though the plus is not at Wally's, and is a bit harder to find than the regular Platinum) is THE best of the non-boutique (super premium, truly fully synthetic, full Group 4 and/or 5 base stocks used) oils which can be 3 times the price (or more!) of the readily available, usually found on the shelf at retailers, oils.

I personally have an extreme case of OCD severe 'overkill', so I use one of those mail order only, exorbitantly priced, truly fully synthetic 'boutique' engine oils (Ravenol DXG 5W-30), and change it out once a year or every 4K miles.

If Mobil1 hasn't given you trouble then no reason not to keep using it - I come from Subarus, which did not get along with Mobil1 back in the day, so I use Pennzoil Platinum.

I remember long ago reading something breaking down Pennzoil Platinum being SLIGHTLY better on turbo direct injection motors, but I have long since lost the link, I've just used Penn Platinum on this car ever since and I've never had any trouble.

It has already been said a couple of times in this thread that this oil will work fine in your car. Relax and use it.
