It seems you are changing every 5 or 6 K miles... and your Mobil 1 costs how much?
Where is your gain? I'm not with you ... I use fleet oil (NAPA) for trucks 'cause it has zinc compounds in it (EP additive)... since EPA mandated all auto oils remove the zinc compounds...because that was damaging the converter element(s). Cheap, too....
