Aircraft
After repairs had been completed on a failed vacuum pump during a previous flight I departed the repair station in my Cessna 210 and was flying solo to [an out of state] airport. About 10 or so minutes after departure and before opening my VFR flight plan; the engine started to lose manifold pressure. I looked at the oil pressure gauge which was reading zero; then landed without incident at a nearby grass strip.
A C210 pilot suffered the loss of all oil pressure shortly after takeoff on a long cross country. He landed safely at a nearby grass strip airport.
