to drain or not to drain

[Railcarmover]

My father ran a '31 coupe from new york to florida on penny a quart drain oil..in 1946..the service stations back then would do oil changes and bottle the drained oil to resell.

this whole thread is a doozy,from 89 year olds diagnosing loose bearings by ear to deciding whether the change the oil when doing a repair..you're just pulling our legs aintcha wingski..you just have to make shit like that up dontcha
