MBUSA's recommended oil service interval for all '09's has been reduced to 10K mi.

Goatman

And as every auto manufacturer continues to do poorly, you will see the intervals continue to drop.

You heard it here first!

TMAllison

I assure you that it wasn't heard here first; been discussed ad-nausem.

Time will tell if the extended interval was truly appropriate or if it got ahead of itself and was leading to problems.

That said, oils and engines continue to improve and some degree of extended interval ought to be acceptable.

Goatman

Ahead of itself? Its been 25K since 1972... LOL.

Just have your oil tested at blackstone labs. They can analyze the oil to tell you how much usage is left. The results will give you a better understanding of how long engine oil lasts in your engine.

Goatman

Amsoil also has a testing facility. They have some big rigs with over 100,000 miles on the same oil....

Goatman

Has anyone noticed all the challenegers and clowns dissapeared since I dropped some resume on them?

harkgar

I think there is more to it than that. GM made diesel Suburbans up till the last couple of model changes and they could have taken this into consideration in its product planning. The high costs (read profit) in the diesel package would negate the attraction of fuel savings. In the Sierra trucks, the package costs around US$10,000.00.

harkgar

Yes. The owners of truck and bus fleets do this routinely to make sure the oil continues to protect and therefore save on the long run.

harkgar

I wish MB would do what GM is doing in crate motors. There are numerous high horsepower engines at good prices. They are brand new and there is no guess work with the output. If MB does the same thing the engines would cost the earth.

Having said that I have seen Seats (Fiats made under license in Spain) with MB engines in Marbella in 1983 as some premium Seat 131 & 132 rear wheel drive models.

I do like the new SRT8 Challenger with the MB derived 5 speed automatic though.

TMAllison

We are speaking mercedes on this forum partner, specifcally diesels. Not big rigs with sumps holding 30 or more quarts pulling down major highway only mileage.

There were syns and MB pontons with 25,000 mile oil change intervals in 1972??? Show me the documentation.

harkgar

Your diesel is one of the best due to ease of maintenance and durability. The newer MB diesels are too complex and too many things can go wrong with the emission equipment just when the cars are worth the least. I feel very strongly against the urea injection method. Car makers are made to put in electronic policemen in the car computers to stop the cars after the urea runs out. The 99 is a keeper. What is the mileage?

Goatman

With the 4L80E trans. Allison is much bigger. Would have meant redesigning the floor pans, console, dash, etc. The new design Suburban was out before the 2001 HD truck chassis (1999 they started), so a redesign would have cost a fortune.


I didn't order my 2001 HD with the diesel for the same reason. It was $4500 more than the 8.1L and Allison at the time and that figured out to be around 5 years of driving with the limited miles I was using the truck for.

Goatman

For what they cost, I first imagined they had an entire MB drivetrain and interior...

Goatman

Amsoil has been around since 1972. Who's used it where is a mystery..


I plan on running my oil in my SDL at least one year or 25K in between full changes. I just need to change the filter every 12.5K, since they don't make the EA filters for the MB's....Yet.... Plus the car leaks some and I'm sure uses some, so there will be changeover.

Untertürkheim

It is not a quesiton of alliances with manufacturers, that is marketing bs. None of the oils except Mobil have any sort of endorsement deal with MB. It does happen to be the case that M1 and Liquimoly are the only 229.5 oils that can be used in AMG, so those would be the only companies with which MB could partner.

TMAllison

I suppose that also means Mobil was making SYN in '72.......That I didn't know. I can promise you that MB did NOT have a 25000 mile interval on a 72 pontoon; 2500 maybe.

Harkgar - Theres nothing wrong with the W211 I6 CDI's except for SBC brakes. They've been around for 10 years already and its a proven design.

The V6 Bluetec is unique from a maint standpoint with matched valve covers, heads, etc, etc. Again, time will tell how successful of a design it becomes. Its been met with considerable skepticism; no diff than much of what others here say sometimes.

Goatman

Mobil 1 didn't know sh*t about synthetics untill Amsoil did it.... Synthetics didn't become "big" time untill the late 1980's... When word of Amsoil started to spread. But by then, Amsoil already had the jump on them all.




That's a easy statement to make, seeing as no one TO THIS DAY has a 25K interval. On top of that no one knew what Amsoil was, or believed its "powers" in 1972. This was basically jet lubricant (the owner was a retired airforce pilot) that he converted for use in auto's.

Goatman

LOL. All the major oil manufacturers fall in line with what the OEM's wish if they want to read their names on their recommended oil change lists..



That's a FACT, not marketing BS..


Perhaps in this 229.5 case, the amount of additives and lubricants in that particular rating are so high and so expensive to produce that only two bother.

Perhaps there's no practicle need for an oil to meet those standards.

Perhaps there are other manufacturers who meet those standards and some folks are shutting the door on those who won't "play ball" with their oil change intervals...


While none of us here knows the answer, the statement and question remain valid on all three of those possible scenarios.

240D 3.0T

Ah, the 'ol net built piston slapper. Good choice.

TMAllison

You're not too good with your facts are you.......?

Go back and re-read MB229.3. Note the 25k Mile interval.

I'd still like to see your documentation that 25k intervals existed in 1972; although you do seem to have refuted your own statement.

Goatman

Note that they just reduced it...



I see the king is back fro another round. I don't respond to swing and misses though..

Goatman

LOL. And I've got you jumping through hoops...


Maybe they should call me the pupett master..

Goatman

Waiting to hear about the kling's race car forays.. If 700 hp is sad, what's 150 in a Volvo wanna-be mean? ROTFLMAO.....

Goatman

Or a fool of you. Whichever one works, right? LOL
