What would be the proper oil to use in my wr450f?
I live in an area where the temperature is mostly below 20 degrees celcius. :cry: :cry:

20 degress Centrigrade (oC) is about 68 degrees Fahrenheit. The Yamaha technical manual for the wr450F suggests 20W-40 Type SG motor oil at 5 oC and higher or 10W-30 at 15 oC and lower. I use Valvoline 10W-40 (winter) or 20W-50(hot desert summer) 4-stroke motorcycle oil, it has worked well for me for many years and is much cheaper than synthethic.
