    3/4 qt per hr oh my that’s it!!!? Was it running?

    Seriously though. That is good.

    Remember the joke the flat engine folks use..,round motors dont leak oil.......they mark their territory.

    Sill that C-45 N491DM would be a nice x-country machine @ 200kt for 1000mi but as you said ~40 gal/hr

    On XC flights my Jacobs 275 HP was good for about 1/2 quart per hour but on short flights for sightseeing or just the enjoyment of it all, it seemed like it was more like a quart an hour. I surmised that maybe the initial start and warm up was responsible for the extra on an hour or so flight.

    Yeah, running was 3/4 at an hour. Sitting, with the “snot box” connected it would leak about a gallon every 2 weeks into the can. Good thing there was just dump it right back into the tank. Just had to remember to be sure to empty it every 2 weeks, but it seldom sat that long without exercise while I had it.

    Just to back up what dgapilot says. The DGA-15 I flew back from Walla Walla WA,- Page AZ,- Houston TX. did not use any oil and it has not in about 30 hours. It doesn't have the "snot box" drain and has 450 hrs. SMOH. Our fuel burn was 19-20 GPH at 170,TAS+-MPH at 11,500' and 9,500' A lot of big piles of rocks to get over
    2000 Miles in 11.5 hrs and one gas stop. A Damn Good Airplane

    Our 1340 in the SNJ-4 will use about 2-3 qts. in 25-30 hrs.and it has 300 SMOH. It has a "snot box to drain the lower cylinders.

    Both these Engines were done by Tulsa Engines. My neighbor's brother worked for Tulsa at the time these engines were done and told me. "If done right they shroud not use oil". The P&W Radial engine has come a long way since 1927
