As an aside. it is interesting to note that many (esp Ford) automobile manufacturers have gone to very thin oils... 15 weight for fuel efficiency, but along with this oil viscosity, accommodating engineering within the engine. That is, smaller oil passages etc.. going to thicker oil, thinking that would be better, wouldn't. The thick more viscous oils wouldn't pass through the smaller orifices as designed for the thinner oil...

The reason I say "theoretically" is the newer specifications substitute "newer" additives in the place of "older" additives.

I was concerned about this a couple of years ago, so I asked a friend who's a diesel engineer. He laughed at me and I felt stupid, but since he makes me feel stupid a lot, I'm practiced at toeing the dirt and turning away when he answers my technical questions.

Yet I, too, still read about smaller clearances on the Interwebz. Just use Google and see for yourself. I guess you pick your experts and take your chances. (That's true in nearly everything, I reckon. Witness the infuriating popularity of "Che" t-shirts with America's college kids.)

The range of 212 degree viscosities for my 2011 RT is 40-50 depending on ambient temps.

The range of "w" (winter) viscosities for my 2011 RT is 5-15w depending on ambient temps.

Lots of latitude there.

About the only oil ruled out by my rider's manual is BMW's own 20w-50 dino oil. But the boss says it's okay for our idyllic climate. Cop bikes use it, too. And since LEOs are never wrong when asking for your license, registration, and proof-of-insurance, I'm betting they know their motor oil as well.

Now I'm perspiring. Is it thoughts of having the wrong oil in my crankcases or flashing lights in my mirrors?

Next time I'm avoiding the controversy and getting Wesson oil from Sam's Club. A 1.25 gallon jug is only $8.98 at the store in Bakersfield.

Thanks for the article, good info. We all sweat about the oils we use. I bought some Liqui-Moly 10W-50 synthetic motorcycle oil from Beemerboneyard. The Beemerboneyard catalogue showed an SG rating on the label. When I got the 5 liter bottle, it was SM rated. I wrote to Beemerboneyard and said they sent the wrong oil. They replied that it was good to use in BMW motorcycles. Not being satisfied with that, I wrote to Liqui-Moly in Germany. They said that the 10W-50 Motorcycle oil was safe to use in BMW's. They said the lower amounts of ZDDP was mitigated by other additives (proprietery I'm sure). I have the unopened bottle in my garage...thinking about it. smirk

Getting it back on topic :-)
All oil changes on my current 2nd hand bike. are done by me, using the recommended oil specifications for my bike and climate.
When the new watercooled boxer comes out (which will be my 1st new bike), all services including oil changes will be done by the dealer for the period of the warranty....no exceptions.

That's what we are doing with our previous and current new car. For the rather small additional cost, it gives us peace of mind when there might be/is a warranty claim.

So..do you need BMW Brand OIL?...NO
Should you use BMW recommended oil specification wise?....YES
Do you need it??..NO. You can use Turpentine instead...it's your bike. Although your bike's durability might be drastically reduced.

Assuming the link works, here in the UK we appear to have a choice.
For what it's worth, our police 1200's get 20W-50, & I can't say that I've noticed them wilting under the pressure.

Good to understand you're talking about BMW USA only. Since they can't get any cooperation in the USA from their worldwide partner Castrol, they contract with Spectro to produce oils they can label BMW in the USA. This happens in USA only.

For those posting about "lighter oils" above, note that this is strictly for fuel economy, as there is less drag with a lighter oil, resulting in improved fuel consumption. It's got nothing whatsover to do with new engine design/assembly parameters. Note also that these companies specifying lighter viscosity oils I think NEVER specify anything but synthetics.

So, a couple evenings ago I got to look over a just-out-of-the box Police R1200RT being prepped at my dealer. It had a BMW (NA) sticker on the fuel tank stating that after 600 miles use only BMW synthetic oil.

FWIW it also had a thumbscrew cruise control, or more properly a throttle lock for maintaining voltage for radios and lights when stopped.

I've been using Mobil 1 15-50 synthetic, 5 quart jug from Wallmart on my 99r1100r. I get a bit of clatter when I first take off until the motor warms up. Switched to synthetic from fossil oil at 12,000 miles, now have 13,800. Did not have the clatter issue with fossil oil. Live in a warm climate, reason for change.

Sounds like you need the cam chain tensioner upgrade.

The radio & the lights run off the "slave" or auxilary battery in the fairing compartment on the right side. They don't run off the main battery. The advice in the RT-P handbook is to switch off the engine when stationary at an incident, as even if the "slave" is run flat, it won't affect the machines ability to be started & ridden away. I've run the lights & radio for several hours at a time, engine off, & no problem. The last thing you'd want to be doing is running an engine whilst stationary with in effect, a raised tickover speed
