Best oil for my Suzuki Bandit 250?

[FruitLooPs]

A new premuim oil and a new cheap oil, to the same API std with the same viscosity and viscosity index will emonstrate the same viscosity charactoristics over the range of operating temps.

What does change is how long an oil will maintain the stated viscosity. That is where quality comes in to play. Extreme service or extended service intervals will likely affect the VI of the lower quality oil sooner, that is why used oil anlysis includes a viscosity check to advise how well the oil is coping with its work load.

at the end of the day it is the correct viscosity of the oil in service that maintains the film thickness

Pretty much this

I've heard good things about the mobil-1 v-twin product from bikers overseas.

Just keep to good change intervals, good filters don't run it hard until its fully up to temp on a motorcycle specific oil of the weight specified and you shouldn't run into any issues. You can run non-bike specific oils if you know the various standards and avoid any oils which contain friction modifiers etc. I believe bike oils are designed with pretty decent shear strength compared to some cheaper car oils (some people run rotella t synthetic diesel oil overseas because of the properties to price value). Not sure if ours is the same stuff though so I stick to bike oils.

Anyone ever tried one of these? And no, I'm not going to. Have my genuine Yammy filter in hand.
