Personally, I wouldn't use oil that is out for pick up at the end of someone's drive way. Knowing what I put into those containers sometimes, I'd stay far away. The last container I put out had some pieces of RTV from the diff fluid change I did.
BTW: A guy I work with has a Saturn SL2 with 200K miles on it. His burned a lot of oil and he did a Marvel Mystery Oil piston soak. He let it sit overnight. Now it still burns oil, but much less than it did before. Its worth a shot.
