I'd be afraid of running such high contentrations of used motor oil often, especially if it is not filtered right.
Here's a quote from the Chevron Lubricants site: http://www.chevron.com/products/prodserv/fuels/bulletin/diesel/L2_qa_fs.htm
Quote:
Can I get rid of my used engine oil by adding it to diesel fuel?
Adding used engine oil to diesel fuel used to be a common practice. However, it almost certainly results in a blend that does not meet diesel fuel specifications. One or more of these properties may be too high: 90% boiling point, sulfur content, ash, water and sediment, viscosity, and carbon residue. A diesel fuel/used oil blend may not be sold as diesel fuel, and we recommend against using it as a diesel fuel.

But I have yet to hear any problems from adding one or two quarts at a time, if it's filtered properly.
