I am aware that the mobil 4t is recomended but as I said I cannot find any in town olny 10/40 that was wy I asked . In one thread It was stated that some of the 10/40 was not jasmo rated but all I have found are and I just wanted To know if anybody was running it and if they felt there was a noticable difference between the 15/50 or 20/50
