I have been using M1 in this engine starting at about 6000 miles.(1 free change from dealer). This engine with slightly more than a year on it has about 37,500 miles on it. We recently got back from a trip to Oregon and back which put 6400 miles on the M1-10w30. Should I change it at 7500 miles...
I have a gallon jug of Wal Mart ATF left over from filling my hyd. lift in my shop and I am curious about who makes this atf. I also want to change my oil in my SS T56. Is this good enough for the T56 or should I get a name brand. Thanks Jimmy
