Thread: oil type

  1. #1

    oil type

    I have had oil head RTs since the first R1100RT. Now with a 2015 RTW, I am reluctant to purchase less expensive engine oil (than the Advantec), as I once did from the more nearby other MC dealers (Honda, etc). Is there a less expensive engine oil which complies with the BMW recommendations?

    Welcome to the forum!
    Oil questions open the flood-gates to a raft of opinions.
    Advantec has a spec to it or you can probably find the spec in the owners manual. As long as it meets the spec, you should be fine.

    Welcome. Here's what I bought (Castrol brand) because it's not too expensive, exceeds BMW's specs for the wetheads, and was delivered to my door.

    You don't NEED the Advantec, but you should at least meet the BMW specs of course - and there are many choices.

    I had intended to meet the specs, but got the impression that few if any other brands met them. Great tip, thanks

    I believe that if a manufacturer requires you to use only their brand of oil, they have to supply it free of charge. Since I don't think BMW wants to give you oil, there must be other oil that meets the required specs.

    Very good find thanks for letting us know. Some of the hype for BMW/Shell Advantec Ultimate is that is utilizes a very uniform molecule size that is resistant to breakdown and *should* retain its full protection for the recommended 6,000 miles. A local rider who is OCD on oil typically changes oil out at 3K miles. He decided to go to 4,500 miles using Adv Ult and sent a sample in for analysis and was advised the oil had lots more life in it and was atypically intact of its important attributes. Adv Ult is made from natural gas. It would be an excellent test to use this exact Castrol product for 6K miles, and contrast the used oil analysis against Adv Ultimate, in water boxers w/ similar miles and patterns of use in similar climates.

    Not so long ago Castrol made the BMW line of oils. Guess Shell had the low bid... er, better technology.

    I've read several posts and articles about a variety of oils testing satisfactorily at 8000 and beyond.

    Just wondering what specs it exceeds when all I have to go on is:

    Advantec API SN, MA2
    Castrol API SL, MA2

    That's got to be untrue. All owners manuals that I've ever read caution you against using "inferior" non-OEM parts and accessories and say to only use their brand.

    I believe that this is federal law about the oil. They can require a spec but cannot require a brand. Surely someone here knows how to verify this or has knowledge of this. They can most likely recommend a brand of oil but not require it.

    Edit: Just found this on the Amsoil. http://www.enhancedsyntheticoil.com/...ed_to_Know.htm

    "In addition, the Federally mandated Magnuson-Moss act states that a manufacturer may not require the use of a specific brand of aftermarket product unless it is provided free of charge."

    They do not say that at all; not in my 2016 manual.

    I'll quote...

    SAE 5W-40 , API SL / JASO MA2, Additives are not permissible because they can attack coated components of the engine, BMW Motorrad recommends BMW Motorrad ADVANTEC Ultimate oil.

    "Recommends" is not "only use their brand". Although I can understand them wanting to use an oil they have experience with.

    The Internet...the greatest source of unconfirmed information.

    Firstly, I said "all the manuals that I've read" so you cannot say that "they do not say that at all".

    Secondly, I said they "caution you against using", which is not the same as a total prohibition.

    You need to work a bit on your reading comprehension.

    Well I have BMW manuals from 1980 to present. Take a pic and post it of what you read.

    Considering you wrote: "say to only use their brand", I don't think so.

    My quote is out of a wetheads (the folder we are in) manual that I actually have, not my imagination.

    Yes, to "say" to use their brand to me, is different than demanding or threatening you if you don't. I did not say they mandate the use of a certain brand, but encourage you to do so. Maybe I wasn't clear or chose a poor adjective to use. My comment was meant in general terms, not specifically toward wetheads or even solely BMW.

    Actually, it's true, part of the Magnuson Moss Warranty Act. A manufacturer cannot make warranty coverage contingent on the use of their parts, unless they provide those parts free of charge to the customer. However, if you use another manufacturer's product and suffer a warranty-covered failure as a result of that product's inferior design or characteristics, you're out of luck.
