international recommends an 85w140 but I cant find a full synthetic at that exact weight. would there be any detriment in using mobil1 75w140 instead? as far as I understand the 140 is the main number the other is flow rate while cold which may help it during winter a bit or is there more to the cold weight than that?
would you recommend mobil1 synthetic or some other brand for this rear axle and diff?
