There is a general consensus that manufacturer oci's are conservative so 7500 oci's with any quality oil are ok.
BUT this does not take account for situation specific variables such as driving conditions, vehicle condition and manufacturer instructions.
So, if you're trying to decide this through judgement / feel, you need to consider these to evaluate whether going to 7500 is ok.
Of course the best way to know is to do a UOA.
Next best thing you can do is search for UOAs.
If you don't do these then go for a extended mileage oil like M1 EP.
Or try to infer something on longevity from PQIAs comparative testing.
My go to oil at full retail (and more so because of rebates) has been QSUD. It and PP, are the lightest 30 weight oils. Synpower and the other brands are heavier and MaxLife I think is heavier.
If I was in Canada, this would be even more important to me.
