In 1983 I sold my last P51 Mustang, the maintenance had become to burdensome. In 1984 I bought my first and only T-28 which I flew until 1998 when I sold it to Russ Myer, the CEO of Cessna Aircraft.
I had flown the T28 in the Navy, it was categorized as an intermediate trainer. You could always tell where T-28s were parked because of the large deposits of oil left on the ground, and the T-28 was referred to as a Thunder Pig because it was such an oily mess. The laws of physics applied aptly to the T-28; when the engine was shutdown, all the hot oil would drain to the bottom of the engine and lower cylinders; then the overflow in the lower cylinders would overflow and leak on the ground and on start up the engine would belch a large quantity of liquid oil out the exhaust stacks. The Navy’s solution was to paint the side of the aircraft with wide black arched stripes on each side of the fuselage to mask the oil deposits.
