Ok it is time for an oil change. This will be the first one since I bought my 2000MM RSV. I went to wally world and picked up some Rotella 15w40 which is an oil many members use on the RSV's. I also picked up a couple of Super Teck 7317 filters. The oil cost $11 for 1 gal. While I was looking at the different motor oils I noticed a Motorcraft 15w40 Heavey Weight Diesel Motor Oil. The Motorcraft wa $11.50 for 5 quarts which is a little cheaper. Has anyone used the Motorcrft Diesel Motor Oil and if you did how did you like it?
