SO Boxer Oil

Any recommendations as to what to use?

ISTR BMW say 20/50, but the only 10/50 I could find was Halfords Classic
Mineral oil.

Any harm in using 10/40 semi-synth? - and does it matter if it's car
oil, rather than bike oil, in a boxer? (I have copious amounts of 10/40
semi-synth car oil)

 

(SteveH) gurgled happily, sounding much like they
were saying:

Don't go to Halfrauds, then...

I wanted it today / tomorrow - not next week.

 

Sling it in! I had 10/40 in the Beemer for the winter rally IIRC and the
viscocity is right for the warmed up engine.

I've always found basic car 20/50 in motor factors and it's what I use. I
don't think old Beemers mind, they just like it fresh and regularly changed.

 

Good stuff.

Next time, I'll buy the Halfords Classic Mineral Oil, as it comes in a
posh metal can ;-)

 

10/40 semi-synth will be fine but there's no real need to be that posh.
Supermarket 20/50 would do fine also.

As I understand it, the only reason that bike oils are different to car
oils is that they have to cope with engine, clutch and gearbox all in
one. Unless it's gone horribly wrong, the oil in your SO Boxer shouldn't
have to do that.

 

Almost tempted to keep the 10/40 for the cars and buy some cheap 20/50.

 

(SteveH) banged this out on the bongos:

Check your local lidl - if they have their own brand in. Meets all the
required specs and works fine in airheads, Ks and Accords.

if you want to errrr splash out

 

That's a very pretty can to leave on display in the garage once you've
used the oil.

WTF is going on with the oil filters on a SO boxer? - never seen
anything like it before.

 

They'd get it to you within a day or two IMHO.

 

IME they don't like running on 40 if it's getting warm outside, but as I
pointed out to the guy who bought my Elise, the UK definition of warm is
slightly different from the, say, German one.

 

They're a bit old school, but I don't really see what you think the
problem is?

 

Just surprised me that it's 2 filters joined by a bit of flexible
plastic.

Need to get the Haynes BOL just to work out where the hell to put
them....

 

The non oil cooler models can take a one piece filter but for the RS/RT you
need the split number to get the fecker in.

 

Ah, OK. Yes, I can see that.

Pay attention to the shim locations too, if it's got any.

 

That filter was developed for the RS, so you could shove it in without
having to remove the fairing panel.

 

Handy.

Just got to find some cointainers for all the used oil I'm going to be
draining out now.

 

Shim locations?! - for an oil change....

 

Some - not all of them - have a shim or multiple shims under the oil
filter cover to ensure that there is enough pressure on the oil
filter. Not a good idea not to have them if you want oil flowing through
the filter.
