Like many of you here, I'm pretty anal about oil and I'm even more nuts about getting oil deals. Of course since I have kids, I'm also concerned about the environment. That brings me to the following story. Growing up I worked for a bunch of gas stations. One of them was an unscrupulous U-Haul dealer. U-Haul used to have to beg their dealers to maintain their trucks, paid the going retail rate to do so. Well this guy would take oil(or ATF) cans from regular customer oil changes and lay them on a piece of angle iron sloping into a drum. This would get every last drop of oil out of them. By the way, I know I'm dating myself with the story about oil cans. I digress... He would then change the oil filter on the U-Haul trucks, add a quart of the "drip" oil mix, bill U-Haul for a full oil change, and send the truck on it's way with the next rental. Living in a college town, the trucks would roll in and out. Hell, he made a fortune doing this. Some time ago I noticed I'd never get all the oil out of a plastic oil bottle. So, using an old Mobil1 5 quart container, I just drain the 99% empty oil bottles all the way. I buy a lot of junker cars and it's a great way to use up the "drip" oil without going into the stash of good oil. Anyone else do this and how do you do it?
