Recomended Oil? WR400

2 posts in this topic

Just wondering what oil I should be running in a 1999 wr400? Should I be running thinner oil in the winter than in the summer? I have 10w 40 in it now and it starts right up everytime.

Thanks,

Austin

10w40 will be fine. Just change it when it needs it. There are lots of oil question threads out there and people will give lots of opinions, here is mine. Use a good oil , change it often ( somewhat ) but the big thing in my opinion is a clean and WELL oiled filter. Keep the dirt out and the motor will last. These bikes are not hard on oil but like all motors hate dirt. My WR has been great and my DRZ has 27,000 miles on it. WATCH THE AIR FILTER MAINT. AND IT WILL LIVE A LONG LIFE.
