Well I would not want to be responsible for an abandoned oil drain pan, i just could not live with that on my conscious :laughing:
Many moons ago tere was a mob who installed coin operated oil pumps at service stations, next to those hot water engine washers, remember them ?
A clever idea for servos that did not have a workshop, drive in give the engine a tib for $ 2, suck the oil out for another $ 2 then go in and find the servo did not have any oil left :laughing:
very quickly back yard mechanics ( like me ) realised for $ 2 I could pump out 20 gallons of contaminated oil liquid waste as against paying $ 50 tipping fee at the local waste transfer station so they started to dissappear.
And cement dust or builders lime dust will suck up oil much better than sawdust.
My floor is carpeted with old rugs I get from roadside clean up.
Much more comfortable to work on, stuff that gets dropped does not go too far away, dust gets caught in it so does not cover every thing in the shop and when they get grotty , roll em back up and put them out for the next roadside clean up.
