Exhausts and Engine » Oil thread - treasure it

Changed over to Silkolene (10w 40) full synthetic and first impressions are that the clunk between 1st and 2nd is noticeably reduced. Anyone else tried this product?

Thanks. I am aware of the difference any new oil can make, but the synthetic seems noticeably smoother than my previous experience with BMW dino oil.

I suspect you took your time and set the level correctly as any overfill will cause additional drag in the gear change as I found out the 2 times my bike was serviced by the local dealer and each time I had to drain 1/2 litre out to bring it to just below the red line at the top of the sight glass. I have used Silkolene and will continue to do so now the bike is out of warranty and home serviced.

I learned a long time ago (flying bricks) that the middle of the sight glass is optimum. Pour in the last half liter very slowly to avoid overfill.

I thought the recommended BMW oil is full synthetic??

The recommended BMW oil for the R1200RS is not synthetic. I prefer Synthetic ester oil in all my bikes.

There is a semi synthetic Advantec Pro and a fully synthetic Advantec Ultimate

“Full synthetic" is a marketing term and is not a measurable quality.

More than you wanted to know:

There are Group III full synthetics that are hydrocracked petroleum (mineral oil in which sulfur and aromatics are removed using hydrogen under high pressure), not synthetic based, Group IV 100% synthetic polyolefin PAO chemical compound based, and Group V 100% synthetic Esters based.

Confusing marketing terms even more: Semi-synthetic oils (also called "synthetic blends") are a mixture of mineral oil and synthetic oil based.

Measured quality ratings include: SAE (Society of Automotive Engineers), API (American Petroleum Institute), ACEA (Association des Constructeurs Européens d'Automobiles), JASO (Japanese Automotive Standards Organization) and others.

Are dealers still doing that?
