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.

I was doing 5k OCI on my Mini, but they had a tendency to use oil.
I do 7,500 in our Expedition Max, and was planning on the same with the FiST.
