I removed all the trucks on all six tanker cars and lightly hit the axle points with the Dremel tool and my problem was solved. They all roll free just as good as other brands I own. The wheel spacing was off some but I left that alone. I ran the cars several times around the layout with no derailments.
Glad it worked for you. Not sure why I first tried it, but it works.
