Dr. Diesel’s First Tech Tip
The following letter was reprinted from Practical Sailor
While the verdict certainly isn’t in yet on synthetic oil, and the controversy bubbles along in the PS Advisor column (August 15, 1993, and December, 1994), maybe the answer is a mixture of both synthetic and petroleum-based lubrication. In assembling and test running Perkins and Deutz Diesels, we’ve determined with heat sensors and visual inspection, petroleum fortified with synthetic oil gives the best of both worlds. We gained the advantages of synthetics without the rapid drain-off from engine castings (leading to dry starts). We’ve used the same fortifying process for other transmissions with equally good results.
