Oil light is triggered by a multitude of
variables including cold starts, mileage, rpm's, etc. but the light should not have come on with such low mileage under any circumstances. But BMW does recommend changing the oil every year regardless of all other inputs.
Only 5W-30 oil with the highest european rating is approved by BMW for the e46. BMW does sell such an oil with Castrol roots. See the oil filler cap on the top of this engine. What does it read?
Do you not have an owner's manual?
Sorry, not my E46. Belongs to a friend of mine...
who's currently in Iraq. Car is at her mother's house, so I don't have access to the manual.
Who knows, I might actually step into the 21s century one day & buy a E46...I know I've been casually looking. Would have thought about a E36 M3, but it's difficult finding one in decent shape for a decent price...a E46 330 Coupe will probably be my next auto purchase.
Not taking you to task, the point being that you
can download a manual for free from the BMW site.
Good running e46 is a beautiful thing! Think about it.
Re: Oil service indicator
First of all, please thank your friend for her service. I pray for her (and all our brave soldiers ) safe return home.
Regarding the oil change, for the longest time I thought that BMW uses a sofisticated sensor that measures the viscosity and chemical changes in the oil, but not long time ago I found out that the oil change interval is triggered by the amount of fuel the engine burns.
By mistake, when I was reseting the oil change interval on a '04 745i I pressed the buttons the wrong way and the amount of gas ( in gallons ) until the next oil change was displayed, if I recall correctly it was around 600-650 gallons. Evidently, the harder the car is driven, the more gas it burns and the more often the oil change. Same with city driving, cold starts, etc.
Yes, it is recommended to have the oil changed once a year regardless the mileage. Computer won't allow you to reset the oil interval if you try to reset before it shows the service is due.
Re: Oil service indicator
What was the price quoted for an oil change? I've stopped changing the oil at the dealer long time ago, the price at the dealer is as high as $200. I buy my owm Mobil 1 synthetic from Costco ( when it is on sale, I pay approx $4-$5 a quart ), buy the filter from one of the discount parts store on the internet for $5 and pay approx $20 a mechanic for the labor.
Thanks Dan! I also purchase my Mobile 1 from...
either Costco or Walmart, and buy my (Mann?) filters from BavAuto or BMP.
Spoke with her mother, and it seems that she thinks the BMW oil is "better" than any other oil she can buy. I'll try to reassure her that changing over to a less expensive brand of synthetic oil won't harm her engine...lol
Costco doesn't carry Mobil 1 0W-40
I'm sure you're changing more than once every 15K miles/1 year.
Just be aware that the 5W-30 or 10W-30 that Costco (don't know Walmart) carries isn't BMW LL-01 tested. The only Mobil 1 that is LL-01 is 0W-40.
Since the other weights are ACAE A1/B1, they can not be used for extended intervals.
The Mobil is not the correct weight at the correct
It is not rated for the 15K BMW prescribed changes.
Probably OK if you use Mobil 1 5W-30 and change at 7K or so.
I found Mobil 1 0W-40 at Walmart and Advance Auto

Sorry my good man, but 15W50 is the recommended
weight for my M88/3 engine. And yes, I was able to source that from both Walmart & my local Costco (although I haven't seen that weight at Costco recently).
The M88/3 engine is what powers my "euro" M635CSi. It is basically a slightly modified version of the engine found in the M1. BMW just had to tilt it slightly to fit under the hood.
Question to begin this thread was posed
with regard to your friend's e46, and this is an e46 board.
Don't know nuthin' bout no other BMW.
