Anybody use this oil? Its only $5.40/qt and seems like it meets the yamaha's specs while being much cheaper than all other types of oil.

If its not full synthetic don't bother in my opinion, unless you change your oil very often, do not use just regular oil. so if its synthetic, and you are able to use such a thick oil where you're located, then go for it.
