Onan Generator in 996 Arctic Fox...how to?

oil drain bolt is easily accessible on the bottom of your Onan the way arctic fox installs it. Pull the drain bolt, drain it, add 1 L of oil (1qt) and your good to go. to check, u dont screw in, this is pretty much standard practice in all small engines as far as i know. Personally i use synthetic oil and change it every 2 years no matter how many hours on it. synthetic also makes it very slightly quieter. If you use regular dino oil i would change once a year.
