Is this legal/valid? If so, why don't all manufacturers do it?

Yes, diets are completely legal and valid and most of us should do so.

Mooney didn't "define" a gallon of 100LL to weight 5.82 lbs, that is
what it DOES weigh. Someone else "defined" it as 6 lbs many moons ago
to simplify calculations. If Mooney is doing as you say (I didn't
take time to verify), then they are just being more precisely correct,
if more impractical for their pilots.


Matt
For 50 gallons of fuel the difference is 9 pounds. Not much of a
difference as most peoples weight can change 4 pounds in a day based on
time of day and water in/out

I didn't say it made much of a difference, just that it is valid.
