what oil to run?

[CarFanatic]

I've done 3 oil changes on my 450, would like to change over to a synthetic, what kind is best? Also what weight?

[feature05]

AMSOIL Formula 4-Stroke® 0W-40 Synthetic

OR

Mobil 1 Racing 4T 10W-40 Motorcycle Oil


I personally use mobil 1. In my opinion these are the best two.

I just bought some klots to try out. I use it in my 2 stroke just ski and its done well, figured I'd try out the 4 stroke stuff.

I ordered the stock weight... is the 0w 40 better?

I'm running Shell Rotella 15w-40 but I have the rekluse, thats what they recommend. Its around $10/gallon at walmart too:cool:
