How do you change the oil on a Honda Elite 80, and what kind of oil should I use?

I have a 1986 Honda Elite 80, and the red light has come on again. I know where to empty the oil, but I don't know:





1) What type of oil should i use? (weather is always 40 to 75 degrees where I live)





2) Do i just empty the oil and refill, or is there something else that needs to be done, like cleaning a filter?





3) How do i get the switch to go back to green once i change the oil. The last time I changed the oil, it stayed on red.





Thanks.|||Hi. Honda GN4 oil in 10w30 weight should be fine. 10w40 would be ok too. Put the scooter on the center stand, remove the drain plug, allow to drain (use a drain pan), replace plug, fill with oil. I don't know what the correct amount of oil is, so pour in 1/2 quart and check level. Set the dipstick on the threads- do not screw in to check. Add a small amount at a time until oil is on the dipstick. For the change light, there should be a slot just under the speedometer big enough for the ignition key to fit. Insert the key and watch the color change from red to green. Hope this helps.|||check out this scooter oil: http://www.amsoil.com/redirect.cgi?zo=14鈥?/a>
