    Is Mobil 1 5w30 synthetic safe on 2001 530i?

    The "service and warranty information" booklet that came with my 2001 530i lists the following as approved synthetic oil:

    0. BMW High Performance SAE 5W-30 Synthetic Oil* (07510017866)
    1. BMW 5w30
    2. Mobil 1 5w30
    3. Mobil 1 5w40

    When I searched bmwusa.com, the following is listed as approved oil(in addition to BMW 5w30):

    * Castrol Syntec European Formula SAE 0W-30
    * Mobil 1 SAE 0W-40
    * Pennzoil Platinum European Formula Ultra SAE 5W-30
    * Valvoline SynPower SAE 5W-30

    Does this list apply only to newer BMW cars? Can I still safely use Mobil 1 5w30 as listed on my maintenance manual? I don't feel like mixing Mobil 1 0w40 with BMW 5w30. Any thoughts?

    I'm sure you can follow either recommendation>>

    w/o ruining the engine. The single most important thing is to change the oil frequently, at 5-6k, especially if you live in a cold winter climate, and the car sees short, low-speed trips. In any event, do not slavishly follow the Service Interval Indicator. Some split the difference, when half the green LCDs go dark.

    If you're changing oil every 5,000 - 7,500 miles >

    practically any of the Mobil 1 products will be fine. The BMW certification as an approved oil is predicated on the ridiculous notion that you might actually only do an oil change every 15,000 miles. I have been using Mobil 1 10W-30 for several years but I change it every 5,000 miles and can't imagine a scenario where that Mobil 1 product would be unsuitable given the frequent oil change intervals. If I'm driving the Autobahn with long periods of high RPM operation, maybe we're having a different discussion but with 5,000 mile changes and very moderate driving habits, I doubt it. The BMW engines are incredibly well engineered and well built but they aren't that exotic. I don't think they are using Unobtanium in any of the bearings. A good dose of common sense will allow these engines to continue to operate flawlessly long after practically every other component has reached the end of its service life. Oh, and the 0W spec is primarily aimed at a trivial improvement in fuel mileage and not related purely to protection of the bearing surfaces.

    However, your mileage may differ.

    No problem ...

    BMWUSA said okay when I queried them in 2001. I've had great experience with Mobil 1. I change every 6K and burn about 1/2 quart over that time (97K miles now). The longer you go between change intervals, the more time you spend at higher rpm, the more you might need an ultra-premium oil (Redline, Amsoil). Otherwise ...

    As an aside, Back in the day BMW used to recommend 3K changes with dino oil, usually 10w40 or similar. Those engines used to be good for about 250K+ before a rebuild was desirable and failures were almost non-existent.

    The M30 engine was bulletproof. My E12, >>

    when sold, had 220k on the clock, and used a quart every 1k. Oil pressure was still 65 psi, and the bottom end had never been apart.
