I'm looking for a true/full/real (pick whatever word you would like) synthetic. Basically I'm looking for an oil with either a PAO or POE base stock.
The two cars that the oil is for, both call for 5W-30 all year round, are a 1997 Oldsmobile Cutlass Supreme SL (3.1L V6) and a 1988 Mercury Topaz (2.3L I4).
At present the Oldsmobile has 5W-30 Mobil 1 in it, and the Mercury has 10W-30 (has to be changed out for the winter) Motomaster Formula 1 100% Synthetic (its the Canadian Tire store brand, and meets the Corvette spec).
The Mercury sees about 5,000 km (3,125 miles) a year, and the Oldsmobile sees about 10,000 km (6,250 miles) a year. The driving is a mix of both city and highway miles, with more city than highway (about 60/40 or 80/20).
I'm basically looking for a synthetic oil with a high TBN (8 or higher) and a strong additive package (I know that the SM oils have reworked the whole additive package and may or may not be weaker, UOAs will solve that question).
Any help and suggestions would be greatly appreciated.
P.S.
If you want to suggest any oil filters that are available in the Toronto area (and where to buy them) that would be good enough for a 1 year OCI that would also be welcome.
P.S.S.
Does any one know if the Motomaster Formula 1 100% Synthetic is a good oil for 1 year OCIs? I think its a group III, but I'm not sure.
