8 gallons
34 quarts
On a 7400, with a 466DT engine, the snow valve is located on the engine side of the air intake housing; which is located on the driver's side of the engine compartment.
The oil capacity is 30 quarts or 7.5 gallons.
If I remember correctly, I believe oil capacity is 32 qts.

The oil system on all DTs from '94 to current holds 30 Qts (nominal) including the filter. Some engines do have smaller capacity oil pans, but they are front-sump type pans (4x4 applications I think).
