Car oil (yes, thin of worms...) experiences

[Farjo]

"I used Castrol Magnatec once and remember the bike absolutely hating it, so i had to get it changed."
"Why would you want to use anything other than what the manufacturers recommend?"
From a previous topic:

Don't use "Magnatec" ... it has molybdenum sulphide in it and that may well bugger up your clutch. That's what Mr Yamaha means when he says "Avoid oils woith friction reducing additives"
Having said that, several on here have used Magnatec or fully synthetic with no reported problems.

Any standard car oil that meets the SE, SF or SG spec or has a grade "CD" or higher will do fine: (ie NOT "Car-lube's" cheapest offering).
Asda or Tesco semi-synth are both cheap and good.

If you like your oil to be "reassuringly expensive" then use something with a picture of a motorbike on the label.
Bike oil is simply car-oil with added marketing by suits that sponsor bike-racing. I have yet to see any evidence otherwise.

What he's saying is that any oil that meets Yamaha's specification is fine, and that some car oils do indeed meet that specification.

Whilst I too have never seen any actual evidence to the contrary, other than a picture of a motorbike on the can, I've never tried car oil, so I too prefer my oil "reassuringly expensive" :\
