E39 Fluid Maintenance Guide

Engine Oil - Varies
BMWs list of approved synthetics (call them 1-800-831-1117) are Valvoline Synpower, Castrol Syntec, and Mobil One, and of course the BMW Synthetic Motor Oil from the dealer, all in 5W-30 weights (5W-40 for warmer climates), but check the owners manual for your model year to be sure.

If you want to have best synthetic, look to Redline or Amsoil.  

I wanted to interrupt this post with another reader who had the following to say [Malachi]:

Unfortunately, that is not very good information…

1) Getrag of Germany has warned consumers to stick with factory fill only and NOT use Red Line due to confirmed incompatibility & failures.

2) Red Line has admitted that their product causes failure in certain Getrag transmissions.

3) The Red Line street lubes being recommended as a "good choice" do not meet minimum BMW specifications. They do not meet minimum Ford, GM, Chrysler or Yugo specs either. They are not appropriate for use in any newer street vehicle of any value. Red Line does not even produce the additives they use in their street lubes. Chevron makes the additives...you know, that famous, leading synthetic lube company, not.

The high number (40) only applies at highly elevated oil temps under severe duty. In this case, the hot oil will still be MUCH thinner than 0W-30 is under cold start. The only difference between this 0W-40 oil and 0W-30 is it'll maintain better oil control (not get as thin) at severely elevated oil temps (240 degrees and higher).

The low number is what impacts cold start wear (the thing that wears motors out). A "wider" viscosity is generally fine, so long as the lower viscosity number (0W) is not higher than the one recommended by BMW.

A anything from 0W-30 to 10W-60 would work, depending upon climate and duty. In Alaska at 30 below zero, 0W-20 in a short-trip vehicle will be "thicker" than 10W-60 in Phoenix. The viscosities recommended by the mfr are for the typical driver.

A 0W-40
oil has a wider operating range than 5W-30. Generally, the 0W-40 oil contains more viscosity stabilizers, so it will probably break down quicker and require changeout more often. For a car that sees widely varying duty (short trip, high speed, cold weather, hot weather), this viscosity is probably a good choice...assuming you change it more often.

 

 

Resume original post:

I think $8/bottle is too expensive for engine oil because I change mine so often (5000 miles), but it is all that I'll use for long service items like transmissions, final drive, or bearing grease applications. I exclusively use BMW Synthetic from the dealer, its less expensive than most synthetics and is made for BMW by Castrol, it is very similar to Syntec, but it has a unique additive package (the one specified by BMW for BMW's, compare Syntec additives to BMW additives at the Maxima website below), but its only $3.42/bottle (with BMWCCA discount, http://www.bmwcca.org) from my dealer. Great price, and the only value you'll every find at the dealer, and you need to get a filter from there anyhow, unless you've mail ordered a stockpile.

Transmission - BMW say's lifetime fluid, I say every 30,000ish miles (Auto or Manual)
Be sure to remove the fill plug first, just to make sure that you can fill it before you drain it. With the Manual Trans I suggest using Redline D4-ATF, or Redline MTL. Amsoil and Royal Purple Syncromax are also popular choices.

With the Auto Trans, I suggest only using the fluid and procedure specified by BMW. I would change the filter every other time (60k) or every third time (90k).

ZF (Esso LT 71141) Fluid Source: http://www.jie.com/, $30/liter at the dealer, $14 here.

Brake Fluid - Every 2 years from the "Date of Manufacture"
Brake fluid should be changed every 2 years no matter what your mileage because it is Hygroscopic and absorbs water over time. For fluid, I think that the ATE Type 200 is the way to go.

"If you have the BMW 4 years or 50,000 miles Full maintenance plan on your E39 it is an included service and its very common for them to forget about brake fluid changes, so remind them. Plus, the fluid change is supposed to happen every two years from the date of manufacture, not the in-service date. So that puts this service out of synch with all the other work that has to be done.", brake guru Dave Z.

Power Steering Fluid - Varies
PS fluid is just like any other fluid and it breaks down and gets contaminated with time and needs to be changed as a preventative measure, unless you think that its a "Super Fluid" and impervious to the elements like no other fluid that I know of. I can not believe that auto manufacturers continue to ignore this fluid in their list of regularly scheduled maintenance, maybe they like being paid to replace PS racks and pumps? I know that bearing clearances inside modern PS pumps are incredibly tight (a particle of anything in the right place could burn it up) - plenty of reason to keep new clean fluid in there. Although, I'm sure the reason that it's not part of the normal OEM maintenance schedule is the likelihood of sloppy mechanics introducing some contaminants into the system, or starting the car with no/low PS fluid, etc... So, the big picture risk of having issues is probably much lower if they just say to leave it alone. So if you choose to do this service take extra precautions and make sure that everything is clean (like you would for a transmission fluid service).

If you are starting with a new car, when performing an oil change service (every 5000 with synthetic) draw the fluid out of the PS reservoir and replenish it with new PS Fluid. By continually doing this you should have clean PS fluid forever and probably will never have to flush the system in this car because this service was started very early on the car.

If this hasn't been done on your car since day one, you might want to do what I did with my car. I changed the PS fluid in it by drawing the fluid out of the reservoir with a simple turkey baster and replacing it with new fluid (synthetic ATF for this car). I did this once a day for about a week when I got home from work, and used about a quart and a half of new fluid total. You could do this all in one day if you wanted to, the key is to exercise the power steering in between draining the reservoir, and I was in no rush. I figure that I changed about 95% of the fluid this way, and it still looks ruby red. Also when performing an oil change service (again every 5000 with synthetic) I draw the fluid out of the PS reservoir and replenish with new ATF, the old ATF gets added to the waste engine oil and recycled. By doing this I hope to have ruby red PS fluid forever and probably will not have flush the system again.

Final Drive - Every 30,000ish miles
This is an easy DIY and only requires a 14mm hex head key or hex head socket and a decent fluid pump to refill the differential case. Again my preferred fluid is Redline and you'll need 2 quarts/liters. You can use 75W-90 or 75W-90NS in a stock final drive, if you've upgraded to a limited-slip unit, you'll need the 75W-90NS. As with the transmission, be sure to remove the fill plug first.

Coolant - Every 4 years
The cooling system capacity is around 12 Liters, for a 50/50 mix of Coolant/Distilled Water you will need 2 gallons (3.8 Liters/Gallon) of each, this will leave you with an extra gallon of 50/50 for toping up later.

BMW Coolant Product Description:
“This product is exclusively formulated and produced by BMW to protect your engine all year round.
It protects against freezing, boilover, corrosion and excessive silicate gel preciptation. This ethylene glycol based antifreeze contains no nitrites or phosphates, greatly reducing the possibility of harmful deposit formation. This coolant is superior to off the shelf brands that contain phosphates. Your cooling system is expensive to replace so use Genuine BMW Coolant.

If you are going to spend the $ on the BMW coolant (82.14-1 467 704) consider using Distilled water ($1/gallon) as the 50% mix suggested by BMW. I just say that because the label on the BMW coolant touts how it was made with no impurities like nitrates or phosphates, why take the chance at adding contaminates back in with city water? I can guarantee you'll at least be adding chlorine and fluoride into your cooling system with city water. I have no experience with well water, but I’m guessing it would contain minerals that would precipitate out into your cooling system.

BMW does not specify the use of distilled water, they also don't specify any service interval for the power steering fluid, but I change that too. Why? Because both are cheap prevention. It cost me $2 more to use distilled water when I did the coolant service. $2 is not excessive. When paying $14 a bottle for the BMW Coolant that claims to be Nitrate and Phosphate free, if an additional $1 will indeed keep that bottle Nitrate or Phosphate (and who know what else) free in my cooling system, then I think I can spare it. If distilled water was expensive, I wouldn't use it, but it is so inexpensive I couldn't justify not using it.

Battery - Yearly
During normal operation, water is lost from a flooded lead-acid battery as a result of evaporation and electrolysis into hydrogen and oxygen, which escape into the atmosphere. I would suggest checking the electrolyte level in your battery every Spring, and topping up with distilled water if necessary.

OTHER NON-FLUID MAINTAINENCE ITEMS:
Engine Drive Belts - Inspection II (Every 60,000 miles)
Spark Plugs - Inspection II (Every 60,000 miles)
OE stock Bosch or NGK, NOT Bosch +4's
There has been more than person that has discovered that their Bosch +4's have "backed out" or worse yet that some or all of the electrodes were actually missing from the plug. I myself found Bosch +4's finger tight after 10,000 miles and I know I torqed them to spec.

Message: couple of the spark plugs were drenched in oil. By the way, the Platinum 4 all 8 of them the tiny electrode had dissapeared completely, like it had vaporized. Put a set of the Bosch coppers from the dealership and the car is not missing any more. However, the power is not like what it used to be. I've gotten a catalytic efficiency a code a couple of times. I am thinking that, I might have
messed up the cats by dumping fuel in them when the car was missing for some time. Once I get the valve cover fixed tomorrow. I'm chaning out the O2 sensors since they are stock and the car has 110K and see what happens.

Message: Hi All, just wanted to send this warning out. I had the same weird idle problem as Ken S. and used some techroline to get rid of it. But it didn't. I took it to BMW and they said no codes set customer using BOSCH platinum +4, not recommended. Bosch recommended them when I put them in but just to see I put the old plugs back in and it doesn't miss a beat. Thought all of you would like to know not to buy these plugs.

Message: I complained to my dealer, they check the codes, none and told me to get the Bosch Plat +4 out, no recommeded. Replaced them with the bosch as F7 LDCR and my smae idle problem is gone. I have a 98 540i 6 speed, hope this helps.

Fuel Filter - Inspection II (Every 60,000 miles)
Raise your car in the air (ramp/jack/whatever) and you'll see a removable panel behind the left front tire wheel well (under the drivers feet in the U.S.). That panel drops down with a couple screws and plastic expansion rivets. You're fule filter should look like 2 Coors Light cans stacked end on end. DISCONNECT THE BATTERY, keep a fire extinguisher close, and wear safety eyewear. Place a tray for the fuel to drip into on the ground, then loosen the hose clamps on either end of the filter. Once it has stopped dripping fuel, then remove the center support for the filter and remove the old filter. You may want to prime the new filter with NEW fuel, and you may need to take the large rubber "wrap" off of the old filter and place it on the new one if your new one did not come with one.
