The official answer is located in the owner's manual, which I highly recommend. If it's not available, and you live in the southern 2/3 of the US, I recommend 10W30 oil that has at least an SL rating (ask your parts store if you can't find it). In the northern 1/3 of the US and in Canada, I recommend 5W30.
