I just bought a BX23s, well, a month ago. Day of purchase, when I checked the engine oil level, it showed about 1/2" above top hole in stick. Yesterday, I did the 50 hr oil/filter change, new filter and 3qts of Kubota oil. I used a vac pump to empty the old oil; indicated close to 3 qts coming out. Dipstick shows, again, about 1/2 " above top hole. Neither the dealer, nor Kubota HQ, can tell me if something is amiss. I have not had any indication; ie frothing, smoke, etc that oil level is too high. Anyone had a similar experience? Any thoughts? Thanks
