I'm a little late on this reply but before running SVO check out the web. Some sites I visited seemed to suggest longevity could be a key issue and recommendations leaned towards using it only in older IDI engines with a limited life expectancy of 10,000 to 15,000 miles. Some European companies warrant their new engines for commercial bio-diesel fuel but I'm not aware of any of them providing warranty coverage if SVO is used as a fuel, which could be another clue to the risks in running it in your power stroke.
