On my M7040 the books says it holds 11.6 quarts or just about a pint less than 3 galllons. Ok. Well was doing the 35 hour oil change on my new M7040 and went to fill it up with 3 gallons of Kubota 15W40 oil. I had drained the used oil into buckets, changed the filter too. Tractor was maybe a fraction low in the front and high in the back but about as level as I can get it. Poured all 3 gallon jugs in and its exactly half-way between the marks on the stick.....it was full on the dip stick before I changed the oil.
So I poured the used oil back into the Kubota gallon jugs and it filled them to the very top of two and almost to the top on another. I would guess the tractor will hold about 3.3 gallons or 12.3 quarts to get it to the top of the stick. So is Kubota saying that the 11.6 quarts gets you to the bottom full mark on the stick or what? I know its not good to overfill a diesel crankcase but I'm already .4 over the listed volume and still have about 3/4" left to go on the dip stick to hit the "full" mark. Has anyone else found that that Kubota lowballs the oil volume in their manuals?
