Where would i be able to test sample of the oils? We did this in the army but i was an operator and never saw it after the mechanics took the bottles. And as for scrap value we have a shredder at the place i work. They paid $300 something for it. It weighs 4460 with my ass in it. I know the core value of engine is $150 and tranny $50. Im pretty sure its got aluminum rims at $8 a piece core value, cat around $50 and brake rotors around 2-5$ each. Battery $10 plus other parts. If it blows i also like making trailers out of the beds and got scrap lying around to make at least two more of em. And as for negotiating price they might drop maybe $50 but they generally charge for what they can get out of it not what they paid. They'd charge $900 to an outside party. But i dont know maybe i do have more room to negotiate with them since not only do i work there i also make as much or more after work collecting metals i bring to them. So i guess if the trucks running not only will it make me money but them as well.
