Was in the oil aisle at Wal Mart today and noticed they started selling gallon jugs of Magna1 10W30 syn blend oil which is FCW-Catalyst compatible for $20.46 a gallon, not bad at all. My buddy just had his new 225 Tohatsus installed on his new boat and he wants to change the oil now that he has 10 hours on them. They call for an FCW 10W30 but my question is, is the FCW catalyst oil any different than FCW oil or should it be fine?
