Does it continue to use oil after the first 2 quarts (if you do not top it offIJ) Our 6275 tractors will never stay at the "full" mark, but seem to stop using oil after it drops about 1_4" down from the full mark. Might just be the nature of the Deutz engine. Has never seemed to hurt anything on the tractors running them just a touch low. The other Russ in Iowa
