06 WR450F Oil...

I live in Australia and i am riding in 30 to 37 degree heat most of the time.
Went to get some oil yesterday and this guy gave me BelRay Thumper 20-50w semi synthetic..............Do you guys think this oil will be ok or should i take it back seeing the reccomendation is a 10-40w?

The 20/50 will actually be better for that type of heat.

In general, a lighter oil flows better, and the oiling system works best when the rate of oil delivery and the volume delivered are higher, not when the oil itself is thicker. 40 wt is really quite adequate for a YZ450, even at 38˚C, but at that high a temperature, a 50wt flows well, and does give a little extra cushion to the ball bearings and transmission.

My range of oil around here is Yamalube, Belray and Motul......Belray is the cheapest followed by Yamalube and Motul is a bit more

"Semi-synthetic" in and of itself doesn't mean the oil isn't good to use any more than "synthetic" automatically makes it good (or bad). By itself, the terms mean fairly little. I know of a few syn-blends that are among the best oils you can get.
