Personally, I would recommend a 10 W 30 oil with ZDDP (Zinc) to protect the flat tappet cam that these engines are equipped with. You can use either a good name brand engine oil, or the more expensive synthetic oil in your engine. Personally, I prefer to use the more expensive synthetic oil. It's a matter of personal choice. Synthetic oil lasts longer, and provides for easier and better cold weather starting, since it does not thicken as much as standard crude base oils do in cold weather.
