Oil Specification

[chang5]

After reading various threads I think I will be using a mineral oil change soon on my new GS,( I think it's lived on a 10w 40 for the past 5 years ) unfortunatly the bike never came with an owners manual so i'm unable to check the oil spec. And to be perfectly honest the codes and lettering confuse me.
Will this oil be ok.

Thanks in advance

20W-50 is what you want. I've always been using this

I was rather hoping my post would have brought it to close

Blown away by the civility of responses here

...so far

For what it's worth, I've used this stuff for the last couple of years. Cheap as chips and comes in 1 litre bottle so if you buy four to do an oil change then you've only got to store a small bottle instead of a mostly empty large one:

With the change, buy some more petrol and ride on

How hard can it be.

How hard can it be.

Completely agree. One thing I did learn from this site though when I started life with the GS was to use 20/50. A good steer. But after that...each to his own.

I've always used 20/50 in my R's, but a when I took it in for a service as I thought I'd let someone else do it used 10/40 semi... a local mechanic with 30+years BMW experience, so I suppose whatever, as long as it goes fine... though I was concerned riding back through Belgium last week with air temp around 30 degrees

Cheers guys i've opted for a semi syn 20w50

10W40 or 20W50 semi synthetic will do fine, whether it is car or bike specific ... it doesn't matter.....at all ... ever

I used to use Halfords own semi-synth 10w-40. Conformed to the BMW specified standard and was a reasonable price. Alternatively get on the Opie Oils mailing list and buy bulk when a suitable spec is on offer. Oilheads are like tractor engines, they don't need super standard oils to run perfectly for 100,000 miles plus.

20w50 API SN, SM, SL, SJ, SH, ILSAG, GF-2, GF-3 etc. rated. You don't need motorcycle oil (JASO MA or MA2 rated) as the 1150 doesn't have a wet clutch.

There's a school of thought that believes "old-fashioned" higher levels of the anti-wear additive zinc dialkyldithiophosphate (ZDDP) are preferable to newer formulations, which use low levels of ZDDP to protect catalysts.

From Wikipedia (other references are available - search if you're bothered): "Oils with reduced ZDDP have been cited as causing damage to, or failure of, the flat tappet camshafts and lifters which undergo very high boundary layer pressures and/or shear forces at their contact faces, and in other regions such as big-end/main bearings, and piston rings and pins. Roller camshafts are more commonly used to reduce camshaft lobe friction in modern engines."

I use this, it's good quality, high ZDDP and not too dear: LINKY
