I have been putting more oil than needed in the T3's engines for a while now , and by accident found out , asked the dealer for a set of filters and 14 quarts of oil , and they told me it only takes 12 now , I asked how did it go down , they said cause the dip stick has been changed because too much oil in the pan was not letting the crank turn freely and causing a running hot problem , so I put in 12 quarts and it was about 3/4 of and inch from the full mark , I marked the new spot with a hack saw , took measurements and from the bottom of the rubber on the dip stick to the old full mark is 5 1/2 inches , and the new mark is 6 1/4 , went back to the dealer and measured the new dip stick and it comes out exactly the same , there are a lot of machines out there running too much oil , what gets me is Bobcat should send out lettters to the owners of machines and give them a new dip stick , all you have to do is remark your old stick , the new stick isn't really expensive $12.00 part number 6690692
