You could go down to a 0w30 if you really wanted to.
I have found that a 15w50 seems to last longer, so thats what I use.
How long are you getting out of the thinner oil?

You shouldn't see a drop in performance if the higher number stays the same. Only a slight drag co-efficient difference as the engine warms from dead cold but never enough to notice a performance drop at temperature. Your ambient temp and riding habits will dictate the oil weight to use. Ontario is pretty cold eh? A 0w30 is fine for colder climates and up to a 10w50 for the hot stuff. I use a 20w40 in Arizona summertime and 10w30 the rest of the time.
my, question is, is ams oil 0w40 safe for a wr 450f or would the "0" be to thin? hard on valves ect? i ran it before for about 300 miles and seemed to work good, then i switched to ams oil 10w40 and found my power had dropped off? also some extra info this bike is a supermoto on road and riddin hard. thanks
