Dieseladdict,

What's the matter, the facts starting to interfere with your fairy tales?

Now that you and the great Larry "change your oil continuously, even while you drive" Bible have been proven WRONG, you go into the attack mode again.

It really is very simple. Just as gsxr said, the 3kmile oil change myth HAS been proven dead.

Get it? DEAD....over with, finished.

Dave, the owner's manuals for the 603 as well as the 61x engines say severe service is 2500 miles, normal is 5000. Su Ritter (author of the MB E-class Bible) said turbocharged engines should be considered as running in severe mode all the time, but I think he meant when using dino oil. Like you said, everyone's car and driving habbits are different. I personally prefer not to go over 5000 miles even with synthetic because 5000 miles for me means almost a year and because I'd rather change it early than bother with oil analysis and save a few bucks.

240Joe, I'm stating the facts here, no fairy tales, and I don't know what you're talking about. I'm really tired of arguing with someone like you who just jumps around and twists what others say. I'm done talking to you.

Dieseladdict,

3kmiles is just a joke under normal conditions. That has been my point from the beginning. It is totally unnecessary, a waste of time and money, and is ONLY based on old wive's tales. There is no modern scientific basis for it.

If you have a OM61X and you use dino diesel oil, and half a mix of highway and city driving, 5kmiles is fine. If you use synthetic under these conditions 7.5kmiles is fine, but many of us are using 10kmiles, or more, and have no problems.

Those are the facts. You can deal with them as you see fit.

Really! I'll have to take a peek at my owner's manual again. Stu's book as a whole slew of errors, I've been meaning to document them & post on the web somewhere (as well as send the list to Stu in case they want to fix it before a second printing...)

"Short trips are the worse, so changing oil at 3000 on a car that never really gets warm up is probably about right."

(240Joe, 03-17-2001)

and

"Let's see if I can get it right....change your oil hot, and change it often."

(240Joe, 01-08-2001)

and

"I couldn't agree with Larry Bible more."

(240Joe, 01-08-2001)

OK, that last one is out of context, but it was just too good to pass up.

Joe, it would appear that you have become much more of a zealot against frequent oil changes then you used to be. Please enlighten us with what caused you to change your mind.

And, hows the weather up there in Collinsville, Illinois?

DieselAddict · #36 02-20-2004, 11:51 PM

Dave, I found it. Take a look at p. 168. Here it is for those who don't have the book (the MB E-class Bible):

"As with all diesel engines, rigorous oil change frequency is the key to long life. The factory-specified change interval for normal service is 5000 miles and severe operating conditions require 2500 mile changes. Turbocharged diesel engines should be considered to be running under severe operating conditions all the time."

The 5000 and 2500 mile intervals match what the owner's manual says as well, though it doesn't mention the turbocharged severe thing. This is for the 616, 617 and 603 engines.

As I said earlier I personally believe to follow what MB says and while it's highly likely one can go over 5000 miles without damage, especially on synthetic, I choose not to because it's cheap insurance and because I don't put many miles on my cars.

Palangi, nice.

Obviously the man converted to the other side.

240Joe · #37 02-21-2004, 08:22 AM

More weak thinking by this group. You need to be very, very specific when talking about oil change intervals. This thread was talking about normal operating conditions on our OM61X engines only.

Many short trips where the engine never warms up is a severe operating condition. Look it up.

And if you are saying I agreed with Larry on something, I'll agree with you.

What's interesting about the Stu Ritter quote is that the Diesel Doctor on MBZ.com changes his mobile 1 synthetic oil at 10kmiles. He is Stu's smarter brother.

Take that.

Why is it that I knew you from Texas before I looked it up?

Where the hell is Ignorant Ridge, TX anyway?

Palangi · #39 02-21-2004, 09:36 AM

Joe, I guess you just knew that a lot of the smarter members and contributors are from Texas. Get used to it.

Thank you for providing all the free entertainment the last few days, but please don't feel compelled to keep making A on our account.

Well, it's been 3000 miles, gotta go change the oil on the old 240D, like the ownwer's manual specifies.

Smarter members from Texas....hehehehehehe...that is funny. You are a card.

Since you base your oil change interval on witchcraft, I've heard that if you put eye of newt in your fuel tank once a month, you won't have any black smoke. Also it cures bad breath and impotency, a frequent Texan problem.

Joe

Palangi · #41 02-21-2004, 10:06 AM

What? The owners manual is witchcraft?

Palangi,

Dieseladdict posted this "The 5000 and 2500 mile intervals match what the owner's manual says as well, though it doesn't mention the turbocharged severe thing. This is for the 616, 617 and 603 engines."

What are you saying?

Joe

Palangi · #43 02-21-2004, 10:39 AM

HeHeHe.... I thought you might take the bait, but you're too smart for that. I was referring to the 75 240D (616.916) where the maintenance schedule specifies 3000 miles.

On the 123 240D's, I believe you are right, the book say's 5000. Since there is very little real difference between a 616.916 vs a 616.912, it makes one wonder why MB extended the oil change recommendation. My guess is, it was because the oil quality improved significantly, say, 1977 vs 1968.

Just for your information, I also think that 3000 is too soon, assuming that a good universal grade oil is being used and no other negative factors are involved. I go 5000 on all of mine. At the moment, For the time being, I have gone to 2500 on the 300D only because oil analysis shows potassium, which is probably from coolant (although analysis does not show antifreeze in the oil). If this clears up over the next few changes, I will go back to 5000.

gsxr · #44 02-21-2004, 10:52 AM

That's another good point. The interval specified in the owner's manuals was based on the quality of oil commonly available at that time, i.e. back in the mid 1980's. When it comes to oils, well, we've come a long way baby! Current Mercedes engines with the FSS setup tell the owner to have the oil changed based on the computer's perception of engine operating conditions, but I think the interval is roughly 8k-18kmi (!!). They also *require* the use of synthetic oils, I believe (don't quote me on that.)

(stir stir stir)

Palangi · #45 02-21-2004, 11:00 AM

Exactly.... The first multigrade universal oils appeared in the early 70's. Prior to that time, MBNA was recommending stuff like Pennzoil 10w40 and actually recommending against Rotella-T. No wonder all those 220D's croaked before 100,000 in spite of 3K oil changes.
