Switching to a synthetic oil helps the engine crank faster when it's really cold. Since switching to the Rotella Synthetic I haven't "had" to use my block heater at all. I just started the SD in 15 degree weather after it had been sitting a couple weeks. No problem. Before, with 15W40 dino Rotella, I had to crank about 20 seconds at 8 degrees once to get it to kick over.
