BMW 3-Series Oil Questions

edited December 2013 in BMW
Hello all, I'm a new BMW E46 330i owner. I bought my car used at a Ford dealership and I am concerned about if they put Castrol Synthetic oil in it or not. My service indicator says i still have about 2,000 miles left. Does the oil really last for 15,000 miles on the right oil? How often should I get the oil changed in this type of car?

Thanks in advance!

    What makes you think the Ford dealer changed the oil?

    Try to get a look at the filter and see what brand it is.. If it is Motorcraft, then head straight to the BMW dealer and pay for an oil change.

    What year and how many miles?

    The BMW branded oil is OK, but I would use either Castrol Syntec 0W-30 or Mobil 1 0W-40. On my BMWs I change the oil at 7500 mile intervals, using a BMW filter and Mobil 1 0W-40 oil. It's an easy 30 minute DIY task.
  • It's a 2003. The car had about 39,000 miles on it when I bought it back in mid-August. There was a "next oil service due" sticker on the window is why I think Ford may have changed the oil.

    Thanks for the advice!

    My local dealers only carry BMW 5W-30 and 10W-60. If I went with 0 weight as you recommend, I'd have to buy Castrol or Mobil 1. Do you run 0W-30 during the Summer and 0W-40 during the Winter? If I understand this correctly, the first number indicates the viscosity of the oil at cold temperature, while the second number indicates the viscosity at operating temperature. Since it's hotter during the Summer, you'd want the lower viscosity number (30) and the higher number (40) during the Winter, no? Also, 5W is for better fuel economy strictly I guess?

    Hey Brave,

    When reading an oil label, the first number means that when the oil is cold, it flows like a straight weight oil of the same number when it too is cold. The second number means that when the multi grade oil is warm, it will flow like a straight weight oil of the same number when it is also warm. Said another way, 0W-40 is still thicker when cold than when it is warm, it just doesn't thin out as much as it warms as a straight weight oil or another oil that starts with the same first number but has a lower second number.

    Regarding fuel economy, the first number only affects the fuel economy for the first few minutes following a cold start. The real benefit of a lower first number is that since it is less thick when cold (especially when it's REAL cold), it pumps up into your engine faster during a cold start and as such, keeps engine wear to a minimum.

    Relative to the oils that carry the BMW label, the 5W-30 is the Castrol oil made for BMW for their non-M cars while the 10W-60 is for the Ms.

    As there is some question as to the true quality of the BMW/Castrol oil, it seems that the best choice for a certified BMW LL-01 oil is either Mobil 1 0W-40 or German (as in says "Made in Germany" on the label) Castrol Syntec 0W-30. As I prefer a spotless engine (on the inside at least), I lean toward Mobil 1 which seems to be unmatched at keeping the innards clean.

    Best Regards,
    Shipo

    Shipo beat me to it, Brave. I think Mobil 1 0W-40 is a better oil overall.

    Does anybody know why air intake should be restricted at low RPM?
    Why VANOS are better than air intake butterfly at low RPM?

  • shiposhipo Posts: 9,152
    One word: Turbulence.

    If the intake system of an engine is too free breathing, then said engine will be gutless until the RPMs come up to speed. Why is turbulence so important? It aids in creating a uniform distribution of air and fuel within the combustion chamber. The better the air and fuel is mixed and the better said mixture is distributed around the combustion chamber, the greater the amount of power that can be derived when said mixture burns.

    That was helpful, I'm sold on the Mobil 1 0W-40.

    Div2, you run Mobil 1 0W-40 year-round?

    Shipo, you know quite a bit about turbulence. Still flying that little Cessna?
  • div2div2 Posts: 2,580
    Div2, you run Mobil 1 0W-40 year-round?

    Yes. That said, my 1995 318ti owners manual states that I can run conventional 15W-50 at ambient temps of 0F and above- and if the car was going to see significant track time I'd probably switch to M1 15W-50. FWIW, I used to run it year-round until the Mobil introduced the 0W-40 grade.

    Actually I'm spending my flying time these days in a fabric covered 1948 Piper Cub "Taildragger" out of a 2,100 foot grass strip. This plane is such a throw-back that it doesn't even have any "electrics". Said another way there is no radio, no navigation and no starter, meaning that you have to yell "Contact" out the window after you've turned on the "Master" so that someone up there can "Hand-Prop" the engine. :shades:

    How's Brave Junior coming along? I'll bet he's getting big. ;-)

    I'm taking early retirement in a couple of years and and if things work out I'd like to find a nice Ercoupe to piddle around in.
  • brave1heartbrave1heart Posts: 2,698
    Brave Jr will be 5 in January, time flies by. He is all into sports - we play football, soccer, hockey or baseball every night - it's part of his bedtime routine :o) He has an imaginary friend called Winner Racecar and he goes racing with him a few times a day - it sounds like someone just fired up an engine and is revving it up loud right in the middle of the playroom. I tell him stories about my own everyday encounters with Winner Racecar who always surprises me when I least expect it with a "Hey, buddy, wanna race?" He wants to go to race camp the day he turns 5 and I think you know what he'll be dressed like for Halloween. My wife had a bear of a time finding a race suit his size :o)
  • shiposhipo Posts: 9,152
    Funny you should mention the Ercoupe, there are a couple of them at the Nashua, NH airport, and I happened to see one of them flying low and slow over our house last weekend. Nice toy. ;-)

    Geez, I remember the bedtime games when Shipo Jr. was 5. Pretty much anything went as long as there was lots of yelling, bumping, rolling around on the floor and such. ;-) He's now 12 and graduated to full time Soccer. He's currently on two different teams that are both nicely positioned in second place, and both of his teams have already managed to beat the first place teams once each heading into the playoffs starting next week. He'll be insufferable if both teams win the championship. :shades:

    BTW, good choice on the Mobil 1 0W-40, I've been using the stuff in all of our cars since 2001 and have had the odd UOA performed on it. It not only holds up very well (per the UOA results), it keeps the innards of our engines literally spotless as well.

    FWIW, I run Mobil 1 10W-40 year round in my M3. Of course, it rarely goes below freezing in Seattle.

    BTW, I'd never heard of an Ercoupe before. I checked the web and it looks like a fun weekend runabout - kind of like a Miata for the sky (where the Piper Cub would be like an MGB)!

    Someday, maybe I'll have the time and money for more toys like those...

    Thank you, Shipo.

  • Hi, new here. Bought a 1991 318i --- took out both oil pans got repaired. Either son or husband drove the car and took out the lower oil pan. What if anything can be done to prevent this from happening? (Can't afford to keep replacing the oil pans). I know its operator error the dealer suggested putting a skid plate over the lower oil pan? How do others avoid this issue? My first thought was to sell it and cut my losses hubby won't hear of that.

    Thanks and I appreciate any advice you can offer
  • Have a 328xi with 800mi and it's down a quart.
    Is this normal ? I added 1/2 qt.but it did not register on the I DRIVE. BMW forgot to put a simple dip stick in !!
    could it be the oil sensor? I have never had a brand new car burn oil.
  • shiposhipo Posts: 9,152
    Relax, many new cars use oil while they complete the break-in process. That said, your sensor should have registered the oil you put in it (BTW, what kind of oil did you use?), so you might want to have your dealership check it.

    I have never had a brand new car burn oil.

    Many BMW engines will use a few quarts until they are broken in. It's no big deal; I've had some BMWs that didn't use oil and I've had some that did. In every case the engines have run past 100K with no problems.

    If you don't mind me saying so I think you guys are a bit too blase about this...you may be totally correct as I've observed the same thing you have, but if I were in his shoes I'd definitely keep a close eye on oil consumption this early in the game....if it doesn't clear up by say 3,000 miles, he's got a problem I think. At his current rate of consumption that about 3.5 quarts in 3,000 miles.

    You know how the odds go in mass production....there's always that .5 of 1%.......

    Well, he's covered by the BMW warranty to 50,000 miles, so I wouldn't worry until there was at least @10,000 miles on the clock. At that point I'd be concerned if the oil consumption was greater than one quart every 2,000 miles.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,619
    True, true...but I'd get the complaints written down early in the service record history so there is at least a paper trail. You know the dealer is going to give you the "acceptable limits" song and dance...what is it they claim...that down to one quart per 1,000 miles is "acceptable"? Is that correct?

    so my concern for the owner is that they'll stall him past warranty if the oil consumption isn't "bad enough" (by their standards).

    A quart in 800 miles is NOT normal. Go to your dealer immediately. Let them clear this and register your visit as well as your concern.

    Oil consumption of 800 miles/qt during the break-in period of a BMW is a bit on the high side, but it's certainly not that unusual. It's wise to report the matter to the dealer, but I'd run the sled several thousand more miles before I'd start to worry.
  • div2div2 Posts: 2,580
    It's also possible that the engine left the factory a half quart low. There's no way to know for sure since Munich has eliminated the dipstick.
  • circlewcirclew Posts: 8,369
    True, but it doesn't hlp much if he doesn't visit the dealer to log the issue.
  • kominskykominsky Posts: 850
    Eliminated the dipstick?! Is that for real? I haven't been paying much attention to the new BMW's since I plan on keeping mine another couple of years at least. Why did they do that?
  • circlewcirclew Posts: 8,369
    Technology Marches On! Yes,I lost mine, too!

    I think it's just like the plastic covers they put over the engine, so it's harder for us to service on our own and need to take it to the dealers.
