I believe Warren Oil makes Service Pro Full Synthetic...not sure about the oil filters as I think there are different ones including their Extended Protection synthetic filter which supposedly competes against similar higher end filters from M1, Fram Ultra, etc.
The one time I didn't change the oil on my old Mazda myself they put a Service Pro oil filter on it. That one was a cheap jobber filter so you'd probably need to know which one it is to assess it. Warrens makes or resells a lot of different private label products.
