#6577 of 8199 Oil Consumption Problems
Aug 19, 2002 (4:12 pm)
If the car has been good in every other respect, I would keep it. I have a 1998 ML that I bought new and now has 56K on it and runs like a top with no oil burning. I run Mobil 1 in it and change it myself every 5,000 miles. Using the FSS system depending on the kind of driving you do, the engine could go up to 12,000 mile between oil changes and that is too much. Ask any good independent mechanic and they will tell you the same. I don't recall what year your ML is but Mercedes only came out with the mandate to use Synthetic about a year or 18 months ago or so and before the switch they used dino oil resulting in some problems, hence the switch to synthetic. During the time while I was using dino oil, I changed the oil every 3,000 miles. I have been driving Mercedes for the last 15 years and have adhered to this schedule and have never had an engine problem. But none the less, get it in and have it fixed and it should be fine. For what it's worth, I would then change oil every 5,000 miles with the synthetic, ideally Mobil 1.
Hope that this helps.

I agree with you - its a great car! I just drove back from Toronto - reached speeds in excess of 95MPH and the darn thing drove like a charm!!! I have a '99 and MB has recommended synthetic oil. Since the filter sits on the top, it should be quite simple to change the oil and the filter. Where did you purchase the oil filter wrench?

(Where did you purchase the oil filter wrench?)
I ordered mine from my independent mechanic, but I'm sure that you could get it from the MB parts dept. or a auto tool store.
I would highly recommend that you get a Topsider that sucks out the oil through the dipstick tube instead of unscrewing the drainplug as it's terribly messy, getting oil all over the tire and the cross members. Any marine supply store would sell it or you can call them directly at 1-800-225-2224 and order it directly. The name is Airpower America. I'm told that you can also get it at Overtons.com. They also are a marine supplier. Many of the MB dealerships use a system that sucks out the oil. If you want to contact me directly you may.

Hi Folks. When I was filling up my ML500 on a very very hot day in the desert, I left the vehicle running to keep the air on. As I unscrewed the gas cap, it ran across my mind that the "check engine" light might come on. (remember reading that in the manual) Anyway, I filled the Mercedes up and then notice that my gas level was showing a little over half full. I put in over $35.00 so I knew it was full. I thought, uh oh, by letting the vehicle run while putting in fuel, I must have messed up something. Well, I watched the gauge for a while (going on a 120 mile trip) and it stayed in the same place for a long time. Then, the needle went up towards full mark where it should be after about an hour of driving. So, since then, no problems and it has measured fine since then.
Someone above mentioned about a "green fluid" on the garage floor. It happened to me too. I noticed I was leaking windshield fluid. (mine was greenish-blue) Apparently, it's a problem on some of these SUV's. A friend of mine had the same problem on his 2001 S500. The dealer replaced it and I'm good as new.
Happy Motoring. M.

Now I know I am not crazy!!!! I have had the exact same problem of an oil consumption issue. I had taken the car in to MB over 6 times only to be told that it does not exist. They ran oil consumption test to determine if leaking...no results. I just accepted that this car burned oil faster than most. I had the '99 ML 430 also until it was totaled about 3 weeks ago. Good news...car was absolutely incredible in handling the accident....I am buying another...hopefully without the oil consumption issue.

I'll try the sources for the topsider and wrench. Went to the dealership this morning to have the oil consumption problem checked out. I was told that adding 3-4 quarts of synthetic oil for every 7,000-8,000 miles was "normal". Also, I was told that they'd be happy to perform the oil consumption test - but I'd have to pay for it! So much for MB's legendary service.
I find it appalling that a Mercedes engine would consume that much oil. Maybe I'm just unrealistic - I'd like to get others' opinion on this.

Almost running out of oil between oil changes is WAY too much. A colleague of mine has a '90 500SL with 43,000 miles in perfect condition... uses NOT one drop of oil. My '91 560SEL began to use oil after 53,000 miles because of a leak in the gasket. While on the interstate, the red light came on and I was not able to stop.... drove it home, put oil in. After that, it would consume about a quart every 1,500 miles then increased usage to a quart every 800 miles by the time I got rid of it at 83,000 miles. The car was beautiful (Black with Palomino hides) but the oil usage drove me crazy.

Finally spoke to a not so friendly "Customer Service Rep" at MBUSA. Who very matter-of-factly said that oil consumption of upto a quart for every 600 miles was normal and within MB's specs. If the consumption falls below 1qt/600 miles, then I should have the SUV checked.
Needless to say, I was stunned!! We've all heard about the Enrons and Worldcoms of the world, I guess in this day and age it's also ok for large corporations to bend reality and stake any position they desire.
Can't do much but vote with my wallet. If anyone's interested, I now have a '99 Silver/Grey Leather ML320 for sale with 44K miles, 3rd row seat, upgraded Bose, and the sun-roof, etc.
#6585 of 8199 Rear post crack
Aug 22, 2002 (4:33 pm)
Has anyone had this problem?
I have a 99 ML320 that is out of warranty. Recently I noticed that the exterior plastic posts on either side of the lift gate were cracked. The seam runs horizontally midway on the posts. I noticed one post had the crack approximately 8,000 miles ago. The opposite post did not have the problem. Upon returning from a 1,900 mile trip, I noticed that the remaining post had the same defect at a similar location.
Today, I contacted my dealership to be told by one person that she was not aware of a structural defect or that other MLs had this problem. I then contacted MBUSA and was advised that they would not advise as the ML was out of warranty and that the dealership should make a determination as to whether it should be repaired by MB as their problem and not mine. The manager of the local dealership contacted me and stated that he had seen similar cracks but because I was out of warranty, they would replace at my expense. They also indicated that if I wanted the regional office to examine it, I would have to pay the fare.
My question at this time is: Has anyone seen a similar defect and what causes the fracture. I don't want to have it repaired only to find that I am doing something to cause the crack

This was a very common issue on this board between 1 and 2 years ago. I have a '99 ML320 and have not had that problem, but many here did and got them replaced under warranty in 2000 and 2001. My guess is that it has to do with the material strength and the stress it takes on the body, but I'm no engineer. I have 63,000 on mine(original owner) and no cracks. I would just fix them if it looks bad and costs less than $500. You shouldn't have to, but we have all realized that we were guinny pigs for buying 1998/1999 models anyway. I learned my lesson no more 1st year models!!! After a couple of years of rattling door latches, sunroof wind noise, mine is very reliable and drives better than most vehicles would with 63,000 on it. I'd trade it but I'm too afraid of all the new junk on the market today and of course, mine being a 1999, they NAIL me on a trade for a new ML, so I may be driving it for awhile.
