I worked for Chrysler Canada in the 1960s in skilled trades as a pipe-fitter.
Part of our duties was servicing the "tank Farm" where the railroad tankers off-loaded fluids for the assembly plant (oil, trans fluids, brake fluid, glycol, etc). A sample from each tank car was drawn and sent to the lab for approval before accepting and off-loading the rail cars into the tank farm storage tanks.
It would be cool if an engineer from Marysville was on BITOG and could confirm the source(s) of those rail-cars in their tank farm
Assy. plant fluids don't come in yellow or white jugs ... they arrive in tank cars
