Ack! I ran Semi-synthetic in my 1776 and it went from a mildly warm running engine to a cooker. I quickly went back to dino and solved my problem. Apparently synthetic sheds the heat into the case, and in our little air (really oil) cooled engines, you need the heat to stay in the oil until it goes through the air-cooler. - Mike White [Mail: mike.white@law.utah.edu - mwhite@eng.utah.edu] Visit my '57 23-Window VW BUS at: [http://cloud8.law.utah.edu/]
