OEW = DOEW + Catering Allowance + Flight attendents
dry operating weight + take off fuel
Basic Operating weight is the total weight of an unloaded a/c, meanwhile, the DOWis the Basic weight+Bags+flight crew+catering.
Yes, trapped fuel is included in the basic weight of an aircraft because it represents the weight of fuel that cannot be used for flight. This weight is accounted for in the aircraft's operating weight calculations.
5w40 is a heavier weight oil at full operating temperatures, but are the same weight when cold.
DOW (Dry Operating Weight) in aviation refers to the weight of an aircraft when it is empty and without any fuel or payload. It includes the weight of the structure, systems, equipment, and furnishings of the aircraft. DOW is used to calculate the aircraft's performance, fuel calculations, and maximum payload capacity.
5w30 oil is thinner in cold weather at 5 weight, and is 30 weight at full operating temperatures. 10w40 is heavier in cold weather at 10 weight and heavier at full operating temperatures at 40 weight.
Takeoff weight is the total weight of an aircraft at the moment it lifts off the ground, which includes fuel, payload, and the aircraft itself. Landing weight is the weight of the aircraft at the moment it touches down on the runway, which is typically lower than the takeoff weight due to fuel burn during the flight. These weights are calculated based on the initial weight of the aircraft, fuel consumption, and payload changes during the flight.

Three tons is the difference between them
about a 75 # weight difference between both sides.
The difference in weight between platinum and gold is that platinum is denser and heavier than gold.
