My 1992 300D 2,5 turbo has 188 000 mi. (need to update my signature). I have it from the last 17 000 mi. (1 1/2 year). Average mpg is 23, ranging from 19 to 29 (half highway, half short move in town, all fill up compiled).

Runs great. May need new engine mounts and glow plugs in the next few months. Front suspension work maybe in a couple of years.

Major repairs to date (don't have any previous records) :
- brakes (disks and pads, 4 corners)
- header pipe
- ASD line and fluid
- oil cooler (road hazard !)
- injectors
- windshield (again road hazard !)

Wow, Dana! Sorry to hear about your problems. I'm not getting warm fuzzies here. I hope I can escape these problems. The previous owner replaced my A/C evaporator at 60K and the engine mounts at 90K. I think an injector was serviced along the way. The rest was brake pad replacements, hoses, fan belt, tires, batteries and routine maintenance.

There are two reasons I chose to buy this car. Safety and fuel economy. My daily commute is 120 miles R/T through rural countryside. It's a comfortable, heavy car that gets 32 MPG.

Every time an unreliable car breaks down on the highway, the personal safety of its occupants becomes the real issue. Regarding economy, I figure if my component failures over the next four years begin to approach $5,000, I'll likely sell the car. Down time can be much more costly to me than shop time.

Jcyuhn, I wonder how the OM606 engine has been holding up?

Hey Guys,

Do you adjust your pump timing as maintenance? Just curious after reading CJ's link. Also, is "P/S service" power steering?

Thanks for the link, CJ. What's that? Fuzzies may be coming back. Definitely some fuzzies here. Any bets Houlihan goes to 500K?

*Laugh out loud.*

Glad to see I'm not the only guy with a shovel and a deep hole. Am 43. Figure another 40 years in snow-free Calif. with my w124 before I tuck it in ... or they outlaw diesel.

Re: mechanics. The dealer may have done a better job. Then again, the dealer couldn't diagnose or fix my handling dillemma, or my turbo glitch (a service manager drove it around the block, said everything was fine, though I had to hit the cruise control accelorator to activate the turbo boost.)

No sour grapes.

My next project: fix A/C -- then repair the dents my grandfather left, paint the car, detail the interior and Presto.

Cherry folly.

Dana B,

Can ya help me out on the soot issue with Mobil 1 15W-40? I checked and can only find that the oil is rated appropriately for gasoline and diesel engines.

Is CH-4 required to suspend soot - the standard was developed in 1998; CG-4 in 1995? Would not seem so if the oils (many others aren't CH4 rated, but are rated for gas and diesel engines.

Am I missing something?

Checked the site below to see if there was something specific ... no joy.

Help.

mine has 113857 miles on the clock. Purchased it a year ago.
Here are things that I've fixed(10k miles):
4 new structs
gasket on the side of IP(twice)
glow plugs
Cleaned seat switches on driver side.
Motor mounts
Sunroof noise
2 new tires

need:

Alignment
Headlight Doors
muffler(has some little holes)

Did a quick fix last weekend on climate control so that I don't have to play with temp. dial in order to get the air come out of the center vent. It's been a puzzle to me. why????

Stephenson,

Not an expert on oil. You might check www.tdiclub.com, then go to the FAQ section on lubricants.

Dana B,

Nice TDI site ... Fred has put lots of work into it!

So, as Fred contends (and in my words) the issue is not so much that Mobil 1 15W-50 won't suspend, it is the level to which it accomplishes this and the difference between that level and what the new standard CH-4 dictates ...

This couple mean, then, that M1 15-50 will suspend only 90% of Delvac's capability within a particular recommended change interval, right? What does your TDI book recommend for intervals?

I would be using Delvac 1 right now if it wasn't so darn hard to find - and to pay for! Example: Would M1, at about $3/qt at Walmart on sale with CF rating, changed at 5000 mile intervals may be equivalent to CH-4 rated Delvac at $6.50 per quart changed at 6000 miles?

Stephenson,

Glad you liked Fred's TDI site. I run Delvac 1 in my VW, which recommends oil changes at 10K miles. Some owners with bypass filters even go further with periodic oil analyses.

But I'm too cheap to run Delvac in my MB. Two gallons of the stuff, available through a local oil distributer or farflung truckstop, would run between $45 and $50. Not sure if I could make it 10K before the next change.

So I run 15w40 Delo 400 or Delvac 1300, sold all over town, at 5k intervals. I should try an oil analyses to see how they're treating my engine.

Would be curious to see the same test done on Mobil 1...

Holy cow, Dana, that's an amazing story. Sorry you had to finance your mechanic's kids' college funds! Ouch.

About the oil, the only Mobil-1 oil you should use is 15W-50. And I've never seen it on sale for $3/qt, at best maybe $3.89/qt. WalMart does have the 5-quart jugs on sale every now and again but only in the 10W-30 and 5W-30 weights, which are too thin (besides, MB only approves the 15W-50 and 0W-40 Mobil-1's.) I'd consider 5k-10k change intervals with either, for mostly highway use, or 5-7.5k around town.

Delvac-1 will suspend roughly DOUBLE the amount of soot Mobil-1 will, otherwise there is little discernible difference, although chemically the Delvac-1 uses a better base stock etc. I am currently doing 10k intervals with Delvac-1 and having the oil analyzed each time (it's only ~$15 per analysis). I didn't drive the car much recently, and my Delvac-1 went 11kmi and 24 months (!) and came back with a perfect analysis. If I drove the car more I could probably extend that to 15-20kmi, although I think by that point the analysis would dictate a change would be needed. I was changing the filter every 5k but Dr. Booth on the MBZ.org diesel list may have finally convinced me it's not necessary.

Also, the only 15W-40 that Mobil makes is Delvac-1300, which is an excellent non-syn diesel oil. Delvac-1 is available as 5W-40 only. Typical price is $20-22/gallon, which is not much more than Mobil-1.

Slowmoe, no, injection timing is not "normal" maintenance. However, IP timing (and timing chain stretch) should be checked every, oh, 30-50kmi depending on how much you drive the car. And it should be checked if you just bought the car.



BTW, my cars and their current mileage are below my signature!


Regards,

Gixxer,

Who's doing your oil analysis? Gotta link? Does your car run better on 5w-40? Any difference in mileage? Am thinking of switching to Delvac...

Dana,

I was getting it done at Performance Analysis, which was something like $45 for three kits. I switched to the Delvac AccuTrack analysis because it was cheaper - $10 for standard analysis, or $13 for the "extended drain" analysis, which checks for two additional items (F-soot and TBN, I think.) You can order the kits from Snyder Petroleum, 1-800-773-8357. Shipping ends up being about $5 so it's more cost efficient to order several at the same time. No link that I know of, sorry.

I don't notice any difference compared to Mobil-1 with the Delvac-1. But it will handle more soot that Mobil-1, and theoretically mileage may be a wee bit better too. Basically, either synthetic will provide noticeable improvements over dino oil (Delvac-1300, Delo-400, etc) but differences between synthetics is negligible. Just make sure you do NOT use Mobil-1 0W-30, 5W-30, or 10W-30! Mercedes has only approved the use of the 15W-50 and 0W-40 variants. The 0W-40 is factory fill now for all Mercedes, gas and diesel, or so I'm told. Very hard to locate though, I've only seen it at the Mobil distributor where I bought Delvac-1 and it was $4.99/qt!

Sorry to hear about your mishap. Well, you could always take this opportunity to upgrade the awful stock lights to some nice Euro lights! The difference it light output is truly amazing, and a pair probably won't cost much more than one stock replacement anyway.


Regards,
