drove to work today in my "new" 715,By the time I got to the yard about 14 miles , I noticed the oil pressure gauge was at 0, I was hopeing it just was a bad sender or gauge ,buttttt I dont think so. I picked up a mech. gauge at the parts store after work , and installed it when i got home, It seems to be slow reading and hangs around 20 to 40, at an Idel it lookslike it drops of the scale
