That happened on a smaller scale in my home town.
Tanker filled the gas tank with diesel at the local station.
While meeting for a ride on a Sunday morning, three of use topped off there.
About 10 miles into the ride, my bike started smoking, as well as the 2 HD's.
I'm thinking head gasket, stuck piston ring? W T H, Valks are not supposed to burn oil. (Or coolant)
I wasn't surprised about the HD's

We all stopped and started looking things over and we figured out all 3 of us got gas that morning at the same place.
We rode on and topped off again after a little while and eventually the smoke cleared.
I blew it off, but one of the other riders couldn't and went back later to the station to complain. Not that it did any good, but he felt better I guess.
I heard some expensive cars had damage to the fuel injectors system and sued, but can't confirm that.
