A "religious" question... (Oil)

[PutteLiten]

Well, it´s an engine oil question.
And, I have learned that Oil is religion, so...

The question is easy.
Can I mix two brands of Oil

I currently have Motul 300V Competition SAE 10/40 100% Synthese in the TLR.
In my other bike I have Shell "something"(Don´t remember the name, blue bottle with gold text) SAE 10/40 100% Synthese. (This oil is acctually more expensive, so I assume they are equally good. more or less...)

Can I mix them safely?

The treason is that I can get Shell easy, and have it in the ohter bike. I have some spare in the garage.
I don´t have spare Motul. And I cant get it easy either. (No local store have them). And worst is that I don´t really have any Motul in the TLR eihter...
Actually, I drove 750kilometers (465miles) with WAY to little oil. So little that it dosent even show in the window when you lean it to the right!!!
(The diod doesn´t flash red on the instrument panel yet though.)

Have I damaged anything??
I drove wery easy, even though I didn´t know there was "no" oil.
I was just doing som touring, and wanted high milage count out of my gas money.


Anyway. I have already mixed the oil. I need the bike funktional.
And it due for service as soon as I can get a time at the workshop. It was time for service, guess it will get new oil then anyway. But untill then ( hopefully ony a few days)...

Help. Scared!

Mixing brands is not a problem. Mixing weights, however, is not good.

Hmmm, oil as religion. How's this: Mixing brands is kinda like mixing Roman Catholics with Russian Orthidox. They'll understand each other and not fight too much. Mixing weights is more like mixing Jews and Muslims.

Nice explanation.

But. Weight??
Is it the 10/40 that is weight?
(Don´t know sh*t about oil, more than 100% Synthese is supposed to be the best for high performace engines - and that is has to be made of gold.... damn expensive stuff... )

Yup. That is your weight.

10/40W is the weight - viscosity numbers.

Thanks Steve, EvilTwin v2 and HandJuice

I filled up with 0.65 litre, and I could use another 0.2 litre...

Anyway. Service comming upp (32000km). 14 day from now. But untill then it will be easy riding.

Actually, mixing viscosity isn't a problem as long as all of them are rated higher than what you need. It may come out a bit "thicker" but won't really hurt anything in the area we're operating.
