Interesting reading, I wish the crappy comments and entire (unnecessary) quotes would be deleted by a moderator, waste of time and space

We're not chumps doing the 'least' possible maintenance - overkill all the way, too may washes, too many waxes, too many pointless trips to the store down the street.

Heck I tie my breakpad wear sensors up in a big knot - the day I let my pads go down that far!!!! As a matter of fact I change my rotors when I change my pads! 'Liftime' on my Bilstein sports meant 10,000 KM

F A N A T I C S

of course we are going to change our oil often WE LOVE OUR CARS! - I would change my blood too if there was a DIY

If you are looking for praticality or reason your in the wrong spot.
Love it!

I probably change the oil too often on my cars because I enjoy doing it. I have several cars and bikes, and I get bored, oil changes are cheap and easy "fun" for a DIYer who wants something to do.

As for me, I do the E46 at 5,000 miles because it takes over a year to get that many miles these days, the E90 gets it every 7,500 miles.

15k oil will lubricate better than 3k oil. The oil needs time to break down, which happens right between 3k-5k miles depending how you drive. From there until 10-15k, the oil is at its optimal state. So the most wasteful thing to do in this situation would be to change the oil at or before its optimal point. That's been discussed on here for years.

I do mine once a year, period. I've never driven this car more than 8k miles in a year.

This. I can't find a direct source, but I've read more than once that the oil must be used for at least 6,000 or more for it to form its full protective coating.

I try to stick to 7,500 mile intervals. My car has 146k has had the oil changed every 11,500 miles on average. Practically 0 oil consumption and no other issues.

I'm interested to see what the inside of the engine looks like. Granted the lead is gone, tolerances are much tighter, and fuel inj has drastically improved efficiency. I'll be pulling my VC sometime soon as it's lkng... I like to see spotless interior surfaces. Judging by my oil filler cap, it's not gonna be pretty.

And I've never heard about oil getting "conditioned"... Link?

Interesting thread. I change mine when the service interval hits 7500 miles, and then again at 0. This typically is about 8,000 miles per oil change with the way I drive. On my other cars, using synthetic, I change at 10,000 miles. I don't think I'd want to run more than 10,000 miles on an oil change, regardless of what the manufacturer recommends. They are in the business of selling cars, not preserving them.

When I got my last oil analysis back from Blackstone, they said to try a longer interval next time as the oil appeared completely fine at 8,600 miles.

I'm old too. Back in the day, our family had a '74 Vega. We changed the oil on the recommended 7,500 mile intervals, and overhauled the engine every 40,000 miles. A friend of mine had the same vintage Vega, changed the oil every 3,000 miles, had 120,000 miles on it, with no overhauls and used/burned no oil.

Times have changed.

I think even BMW's standard 15k interval is on the conservative side for their recommended LL-01 oils.

I am fully aware of the time it takes for a generation or two to pass. LOL

"Pass" is an ugly word to those over 50, sonny. Respect your elders.

LOOOL

I meant for their (mis)conceptions and all to pass. It is amazing how those kind stuff will stick for a whole generation no matter what. Well, I will have some for my generation that my kids will laugh off for sure.

OMG! The Cosworth Vega! That was THE car to have in the late '70s. How often did people change the oil in those?

5,000 Miles. I plan to do it in a few days, maybe less than a week. They aren't that expensive, and make your car run better, and for longer, so why not? And Stick with the LL-01 specified SYNTHETIC only engine oil. Get the Mann or Mahle (oem) filters as well.

For the first 120k it did my oil at intervals of 15k

After that for the next 60k miles, I did it at every 10k

From 180k miles to current 205k miles, I change it at 5000-7500k.

Last couple were at 5k

This was advice I have so far followed that was given by 2 separate BMW specialty mech's; both with 25+ years experience.

No complaints so far.
