Oil, yes I know, again !

[David.]

One Oil I have looked at as an alternative to the Castrol is Morris Super Sport V Twin 10W-50, http://www.morrislubricants.co.uk/produ ... 0w-50.html, this is a Motorcycle specific oil, which currently costs £32.00 for 4 litres.

For £30.00, you can get 5 litres of Morris X-RPM Competition 10W-50 (car oil),  http://www.morrislubricants.co.uk/produ ... 0w-50.html, similar to the Total Quartz.

Both oils are available from Andy who has a Unit adjacent to the Riverside Stadium in Middlesbrough, he can be contacted on 07931 770494.

Andy also does Service Kits for RT's on ebay, looks like there may be a choice depending on which make of Filters you prefer.

I have an LC bike with wet clutch so have to go for bike oil. Due to warranty I have stayed with what BMW have specified.

As yet no Shell branded 5W40 just BMW branded made by Shell. Asked how much ? £16/litre. I'm sticking to Castrol Power 1 4T 5W40.

Should you now be using BMW Advantec to maintain the Warranty.

If & when I buy a BMW Extended Warranty, had I better do an oil change.

I've found the correct Oil, "Does exactly what it says on the tin".

Crikey, £16 a litre. We're going the wrong way !!.

I do seem to remember having Motorex Oil fitted to one of my BM's during a service at Barrie Robson's quite some time ago. "It's the official BMW recommended oil Sir". Eee ba gum. what goes around comes around !!.

It's also strange that between 2007 & 2010 during my Ownership of a Hexhead, BMW in their wisdom decided to change the recommended oil from 20W-50 Mineral to the 10W-50 Fully-synthetic, now work that one out!

BMW Motorrad UK
20W-50 will be ideal, although we have just introduced the Power 1 Racing 10W-50 full synthetic which is BMW preferred grade now for the boxer engines, so if it's run in and you want a higher performance product, the Power 1 Racing would be the best oil for protection and performance - but Only BMW will carry it."

So, BMW have gone forward from 20W-50 Mineral to 10W-50 Fully-synthetic, then backward to 15W-50 Semi-synthetic.
The greater the Viscosity range (10W for cold start) & the higher spec. Fully-synthetic, surely gives the best Engine protection.

Excellent article in the quoted link from David. The writer mirrors everything I have always thought about BMW and Engine Oil.

Incidently, David, did you ever find out just what caused the partial cylinder seizures.

"Incidentally, David, did you ever find out just what caused the partial cylinder seizures."

I'm not too sure that they ever got to the bottom of it.
The reason given by Cooper Sunderland was that BMW were investigating a number of Piston Crown failures, whatever that means.
I was told that the new Pistons fitted were of a different design.
