The main reason being--1 gal mogas= 7.422 lbs.
1 gal avgas= 6.978 lbs.

Avgas has a density of 6.02 lb/US gallon at 15 °C, or 0.72 kg/l, and

The Avgas weighed 168.3 gms/250cc---The Mogas weighed 179.0gm/250cc----

Please let me know If I made any mistakes in the conversion----If not,
I'll re-weigh two more samples tomorrow..

Plugging your avgas numbers into my conversion software, I get 0.371
lb / 0.066 gal for your measurements ... which my calculator gives as
5.62 lb.gal. I didn't run the mogas.

One of us has bad conversion data, maybe both of us.
