In my 1990 E34 535i, 5 speed, 103K miles, I use dino oil. I found that
at about 2500-3000 miles, my oil is black and very dirty. So it gets
changed. I think more important than mileage is the type of driving you
do. If you drive mostly freeway with very few stops, then a longer
change interval is warranted. However, if you're like me and live in a
City with lots of hills and stop and go driving then a shorter change
interval is needed.
The service indicator already takes this into account.
Actually, the current service indicator is run strictly by fuel usage.
After so many liters, a light goes out. X's 5 and its the yellow light
indicating the oil change. Fuel burn (greater in urban than highway) is
a good approximator of the oil's condition, but not absolute. There's no
oil analysis going on under the hood.

No, there's no analysis, but the calculation is more complicated than just
fuel burned.

Not according to my technically proficient sources. Used to be some other
stuff figured into the equation, but BMW determined that total liters burned
was a good enough solution.

You don't want runny 0W30 synthetic in an older motor, but synthetic of
the same viscosity (20W50?) as the dino you're using, or as specified in
the manual, should show significant benefits.
Black is not the same as dead - diseasels can make their oil look foul
in a few tens of miles...

Re: Vaccuum tubes |

My Dad was in car business all the time I was growing up. I worked in a gas
station as a kid. I've done all of the general maintenance in every car I've
ever owned. And, I've never seen a need to replace all of the vac hoses. To
be honest, I've only seen two or three hoses in my life that needed
replacement, and most of these were repaired by simply snipping the end off
that was cracked.
I gotta wonder if you arrived at this diagnosis on your own, or if a shady
mechanic is feeding you a line of crap ...

1)Is this something relatively easy to do on the I6?
2)Is there an online diagram that shows where these are located?

I haven't dug into it yet. I came to the diag on my own and asking on here.
There is a hissing noise from the drivers side of the I6. When Idle over
time the RPM's will 'dip' and almost cause the engine to die. As the time
goes longer they get worse and after about 15 mins the car dies, i can
imediatly restart the car and the prossess starts again. When driving its
fine, only time this is happening is when the car is Idle.

Well, yau are describing a vac leak, but there is seldom a need to replace
all of the vac hoses. Find the one that is leaking and replace it.
Have you considered the power brake booster? I've heard of this developing a
tear in the diaphram inside, and it can cause a vac leak. Try applying the
brakes at idle and see if anything changes ...
