Car oil

[lcarron]

Hello

I can’t find any 5w40 oil for my 2021 s1000xr unless I order it online at $20 per quart.
I found some Mobil one synthetic 5w40 for European cars with the same specs but wondering if I can use it, especially for the clutch.

The label says.
Meets or exceeds the requirements of:
-APISN, SM, SIL, SJ

What do you think?

Do not use car oil, most car oils usually have "friction modifiers" in them which may make the wet clutch in your bike slip. Use only motorcycle specific oils.

You can use 10w40 if you live in a warmer climate, I've been running 10w40 shell advance ultra 4t for a while now and it's cheap and basically the same stuff as BMWs own Advantec Ultimate (since Shell makes it for them lol)

Here in Aus where we often get silly 40C+ temps I run Penrite 10W60 Full Synth in mine...have done since the bike was new.....just ticked over 50k km now and no issues to speak of. Engine internals were as good as new during the 30k km service.

I know I will get a backlash for this, but I use Mobil 1 (normally 0-40) in just about everything.

Great oil and a fair price, never had a problem and never had a clutch slip because of it.

I have never run it in a BMW though - they have always been kept dealer serviced
