How often do you change your oil?

[Jsantos]

5k

For me, its either 4.5k - 6k miles, or every half a year whichever comes first. I love doing oil changes =D I always look forward to changing it that usually i change it too often too.

As one person said previously, short oil change interval might be a waste of money and oil (especially those who do oil changes based on analysis), but it is also a cheap peace of mind, so i totally dont mind doing it more often than not. Cheers

I change it every 7.5k miles. I think that's reasonable.

[e92zero]

Every 7.5k here.

[w0ady]

5k since I track.

[E36Racer]

Blackstone will tell you how long to go. For me they recommend 9.5k

For the first 4 years, BMW did it once a year, which averages out to 8k. Since then I have done it about once a year, which probably also averages out to 8k. I don't track the car.

I think BMW's original 15k mile intervals were probably too long. I also think 5k is probably too short.

I'll do every 7500-8000 or one year. Whatever comes first.

Just got mine changed today. My fellas used Liquimoly in preference to Castrol. I've heard from 3 separate BMW service agents that Liquimoly is the best oil to use. I was strongly advised to ignore the car's service alert for engine oil changes and stick to 10,000km intervals.

Since im supercharged every 5k, sparkplugs every 15k.

I changed it whenever the CBS tells me to or once a year. Whichever is sooner.

I purchased a 2011 M3 E93 with 72K miles on it. Had an oil change at BMW just about two months ago and about 4500 miles later. I like to drive the car. I received a message yesterday indicating that I need to add a liter of oil. I found this strange that this would be required so soon.

Is this normal or should I begin to think that something is wrong with the car?

[BayE30]

adding 1L @ 4500 miles is not out of the ordinary. instead of adding oil, i tend to change my oil around 3500-4000 miles. Being as how i drive my car only about 4k miles a year, this equates to 1 oil change per year, and im more than happy with that interval.

[Logitech]

I did mine at just about 1k. I changed it because it was 1.5 years since last oil change. Tells you how much I drive. They gave me back the original filter in a bag. The oil was still super clean.

I wont' make that mistake again. Waste of money. I just thought it wasn't a good idea to go that long even with the low miles.

[pbonsalb]

If you burn 1L every 1000 miles and add new oil, could you change just the filter and extend the oil change interval?

[M3ANMACHINE]

Every 5k miles. I don't burn any oil after adding Liquimoly MOS2 at ever oil change.

[Mpow-wow]

5-6k liquimoly
