Do you wait untill the computer tells you to do it or just do it on 5k,10k and what comes up- oil service inspection1and2 . I got 1995(E36)with the blocks counting down across the bottom.

I wait until it goes to the yellow and says oil service. It's a tiny motor with a huge oil pan. No need to do it any sooner. Waste of money, and I know people with disagree. IF my motor does die though, it just gives me an excuse to upgrade!

I did follow that and I only did 2 oil changes in a year and a half!

Most people with older cars will come and say, change it every 5K, not realizing that new cars have changed a lot.
I too changed my oil at 5K for my older cars.

On my 97 e36 with synthetic, it used to do oil changes every 7K
(before the lights run out).

On my E46, with synthetic, I change it every 10K
(BMW recommends every 24K, but I do it much earlier).
I also had some head mechanics at BMW recommend 10-12K intervals rather than the 24K.

I never let the oil or the filter get over 12 months old.

I just do every 10,000 k on my 98 528i with over 230,000 on the clock.

I talked with the service tech last time I was in and he said: "Bring it in when the computer says its due". I thought 24,000kms was a long time. He said the filtration systems are very efficient. The actual oil does not "break down" for quite a while, so lubrication is not the biggest concern. It the filtering which eventually starts to become compromised and that is what the computer is monitoring.

I don't want to be doing damage anymore than anyone else but at the same time you have paid more $$ for a car with highly efficient filtration system then you're spending $60 every 8000k, to throw away perfectly good oil...I don't know. I'm tempted to get the old oil anaylzed after it's changed.
