Ya, well over on this side of the pond, we used to
use old motor oil for killing weeds, now I know
that isn't very green

I wash mine constantly at the wash a block from my house before I park it for the night. I also go wheelin in the snow at least once a week. I think the fresh powder cleans out the under carrage well. Ive been lacking on the snow wheeling this year cause were really really short handed at my job lately. Its hard to find a good, and fast mechanic.
