Tony - you might consider renting a ride on floor scrubber. All of the commercial cleaning companies that I've seen use this product with good results use the ride on scrubber. Probably have to make several/multiple passes with it too. This is not a miracle solution if the machine oil has been there for decades though, once it gets into the concrete unless you shot blast the surface (which creates other issues and even then it's likely the stain is permanent) it's not coming out.
