Thank you for your concern(s) and advice(s).
It has been long time since I last typed a message here on this forum. However, I would like to make a announcement that I have actually bought the 2003 BMW 530i with 111,000 mi. We did look at other vehicles like economy class ('07 Camry with 27,000 mi, '05 Focus with 85,000 mi, '08 Dodge Avenger) before the purchase. We test drove all of them. They were in the range of 10~18 grand, however, we could not get a good deal especially for the camry. Any ways, I am happy with the purchase and the car is running excellent. I changed the rear brakes and the alternator all by myself. Changed the spark plugs and put a new K&N filter as well as did synthetic oil change. Topped up the tyre pressure as per the specs. Initially in the first week I was averaging about 18~19 mpg, but now with the tune-up I am getting about 22~23 mpg in city driving. How about that!!
Thought I'll just update you guys. That's it for me to say now.

I highly recommend you pull that K&N and put a standard paper filter back in; you're fuel economy and performance will be just as good and you won't run into any airflow-sensor issues. As for your engine oil, did you use an oil that is BMW LL-01 certified? If you didn't then I suggest you change it again with something like Mobil 1 0W-40.
Enjoy your car.

I would agree...ditch the K&N asap. It's not helping you.

I used the Mobile 1 oil 5W30 as per the spec given in the book. The K&N filter is the same size as the standard filter. I am aware of such tune-ups where one removes the whole air box and the airflow sensor and being replaced by aftermarket air intake system which runs all the way to the throttle body. However, this is not the case with mine. I am not one of those typical tuner where I seek power or anything. I have used K&N filter before in other cars and I have seen some difference (namely improvement in performance). However, I am not going to ignore your advice as I shall observe the performance for over a period of time. If I think it is not giving me any improvement/advantage but instead problems, then I shall replace it with the standard filter.
I appreciate your concern very much.

"I used the Mobile 1 oil 5W30 as per the spec given in the book."
You need to read it again; unless you're using the Mobil 1 ESP 5W-30 then your oil is incorrect and insufficient for use in your car. The only two Mobil 1 oils sold in North America that are BMW LL-01 certified are Mobil 1 0W-40 and Mobil 1 ESP 5W-30 (which is an expensive low SAPS oil meeting the VW 504.00 and 507.00 oil standards as well).

I couldn't find an LL-01 certification on the Mobil 1 oils. The last letter I saw showed them as an alternative for a top off IF you couldn't find one of the LL-01 oils. Now, not sure it they would actually meet the spec, as they'd probably have to pay for it and may not care to. So, as I read it (and I could be wrong), they should not be used during a full oil change. Probably won't hurt, but possibly could.

I do not know what the difference between LL-04 and LL-01 is, but Mobil lists the former and not the latter in it's specifications, which is what they now specify. I'm new to BMW, and have no experience. I won't get mine back from the European delivery until the end of the month, so it'll be a long time before I have to pay for an oil change, but I've been looking to see what's around (not much, and hard to find).
What you might want to do is send some oil out for analysis after maybe 3K miles, and see what it's doing. SHort enough where it probably won't do much, but early enough to see if it is lacking. But, at the cost of the analysis, I'm not sure...this isn't my area, just going on what I read.

Same thing here. I do not just buy things blindly without doing some research. Even though I have worked as a mechanic for about one and half years I do not have much experience on european vehicles. I have mainly worked on japanese and some american ones. So I need more time to know about my car, and general BMW(s) information and maintenance records.
#2614 of 2735 BMW Oil Specifications...
Jun 15, 2011 (3:13 am)
BMW Long-Life 2001 (aka. LL-01) is BMW's required oil specification for ALL late model BMWs with a gasoline engine (except "M" series cars).
BMW Long-Life 2004 (aka. LL-04) is BMW's required oil specification for ALL late model BMWs with a diesel engine.
Mobil 1 oils which meet LL-01:
-- Mobil 1 0W-40
-- Mobil 1 ESP 5W-30
Mobil 1 oils which meet LL-04:
-- Mobil 1 ESP 5W-30
Simple as that.
