M20J Range

[McMooney]

not a j but in my E with 52 gallon tanks, i do approx 3 to 4 hour legs.  actually it's more based on which tank i'm on,  i start on tank 1, switch after an hour, empty tank 2, land.   tend to land with  15 to 20 gallons of fuel.

I use about 8.7 GPH (LOP) at 8-9000’ but plan on 9 for easy math and to be conservative, so 7 hours is my absolute limit, but 6 is the maximum I plan for. This gives me conservatively 150 kts TAS, so no wind absolute max range is 900nm.

The longest I've flown in the mooney was a 4h trip. I like to run LOP at lower RPM settings, so I consistently get lower CHTs and fuel burn (1990 M20J).

Cruising at 11,000, WOT/2300 and LOP I see between 7,5 and 8,2 gph at 143kts TAS.

The longest I did in my E was 5:12 covering 993 sm (863 nm) at 13,500. Landed with 8.8 gallons left out of the full 54.8. The winds were good at altitude, and using oxygen kept me in good shape.

I once flew from KRDM KCHD. it is a little over 800. @201er holds the record on here, but he has long range tanks.

My F is essentially a J, although turbonormalized so I can fly in thinner air.  BOS to OSH is about 750 - 800 miles.  I have done that trip several times landing with 1/4 tanks remaining, 75% power, 100 ROP.

This is with long range tanks, 90 gallons.

So, what? Not my idea of a pleasant flight experience just to save a 45 minute stop.

Additionally, my wife is not enamoured with the Travel Jane solution (or, any other in flight 'solution')

You, and your wife's, mileage may vary.

I just hate to come down from the teens and have to climb back up again.

My SO is not happy with the solution, but accepts it.  We found a silicon funnel on Amazon that works better.  Still use the Travel Jane as receptacle.
