what oil....

[Crazy-Duck]

Morning all.

I know this may seem like a bit of a daft question, but I noticed yesterday on my way home from work that I need to top up the oil in my monster. It was too late to go anywhere and get some so thought I'd look in the manual. It says 10W/40, I have some of this laying about in the garage, but it's the rating bit I dont get. It says equivalent or higher than SE, SF, SG.
Please help.
Thank you.

SF superseded SE, SG superseded SE and SF.

Any modern 10/40W oil will be fine unless it's something like Magnatec with friction modifiers which can cause clutch slip.

Thank you!

I am always told not to mix semi with fully synthetic. Best to check which one your bike has in it before you do...

You can mix mineral, semi- and fully-synthetic as much as you like.

If you have a 10W-40 oil available it will almost certainly be fine - 10W-40 oils are not used in energy-saving applications so will not be full of friction modifiers or anything.

If I understand it correctly, semi-synthetic oil is a mix of mineral and fully synth oils so yes....they do mix.

In olden times, (I'm 53 you know), mixing mineral and synthetic two stroke oil would be disastrous which could be why so many people are under the opinion you can't mix engine oils.
