Because you can drive a Mercedes engine all day long at redline .... as long you keep the oil CLEAN!!!!

Mercedes engines will not tolerate running out of oil or running dirty oil. The old addage pay me now or pay me later comes to mind.

I agree 100% that engine oil must be topped up and clean. I was taught that in High School shop and stands almost any logical test that can be applied.
But I have never received an explanation why my three beaters that should have stopped running at some point in time did not! If the theory that proper, quality, clean and full oil makes an engine run a long long time, then should improper, alegedly poor quality, certainly dirty, but always full oil result in a grenaded engine? The theory is wrong; I proved it wrong.
A lot of people here claim one must use synthetic and one must change it often. Often there are arguments as to which brand is the only brand to use. My actual experience has disproved all those. And let me tell you, that 3.0 litre Chrysler motor was at redline while pulling the trailers. For many, many miles. I did have to put the heater on for a while because I saw the temp gage climbing.
And I would say that there are not major differences in crankshaft loadings and oil shear loadings in most engines regardless of RPM/howrsepower/torque ratings. Mercedes, Nissan, Plymouth, Chevy, Mercruiser, Crusader, Caterpillar, Cummins, Mann, MTU, even high speed deiesels like Yanmar. The same oil is used in a 3500 HP 16 cylinder Mann diesel as in a 90 hp 4/5 cylinder diesel engine made by Benz or VW or any other.

Having been in the lube oil business for over 30 thirty years, i cant help myself to enter into this topic,,,,,27,000 miles. well enought has been said about such a task...but to get back to reality, many a factor accumulate to the lack of req. lubri. in an engine oil.....i wont bore you with it all, the only real answer to lenght of time b-4 need changing is done with reg. oil anayl. to determine additive and unwanted devils claiming residence in the oil pan,,,,i also dont mean to be unfair to our friendly well meaning mechanic, but most do not recognize a bearing failure due to ozidation, lack of oil, worn out oil (additive package used up), and my favorite........oil break down???????? ,,i dont know just what that really refers to, therefore change oil on a reg. basis no matter what brand or color using, or have oil anayl. done on a regular basis..jack

waybomb - you are an amazingly lucky person, I think.

I inherited my dad's 1979 Volvo 240D when I was a kid.

I let the oil go for 7k miles.

Seized the cam (as I mentioned earlier). The techies at Marten's Volvo of Washington said: "Yup, skipped the oil change, didn't you? Also snapped the timing belt when it froze, didn't it?"

Fortunately, the head could be remachined.

Later I was told that these Vovlo engines are built to last almost forever, PROVIDED that you do that Castrol thing religously and regularily...

Proved "wrong" on American and Japanese motors. I don't think you'd have similar results with Euro engines.

I think the oil debate is right under Religion and Politics! I have seen verbal throw downs on other sites about what oil to use and when to change. This is how I see it on two of the topics in this thread; Cars that run a long time with never changing the oil depend on a few factors, the way they are driven and the quality and care of their build. I had about 13 cars between age 16 and 25, the one that stands out was a Pontiac 6000le with a 2.8 multiport. I beat the living hell out of that car daily racing my friends who all had Audis and VW’s. I sold that car with 220Kmiles on it! I did change the oil every three K but here is the part about the care taken when it was built, All of the other American made cars I had which I took better care of and changed the oil every 3k did not last near as long. My other thought on this idea of no oil changes is this, Oil is the blood of the car and gas is the food! What happens when your blood is toxic? Same idea for a car! Also I think we can consider the engine in the 560 a high performance engine for those year ranges. In a high performance engine the conditions are very demanding! At the end of the day it is all opinion. My 87 560sel gets Mobil 1 10w-40 high mileage oil in the summer and Shell Rotella T6 5w40 in the winter. Now to start a real fight on this topic,,,, I also use the Shell Rotella T6 in my motorcycle!!!!!! I can see the pitchforks and torches coming already!

But....

When I was around 18, I bought a used 1970 Chevy Impala from an estate with a 350 and a turbo 400 (came like that from the factory!) It was a light green 4 door with a kinda green, kindaq tan plastic interior. I got it for a song and what the heck, it was my beater. A good beater because it only had about 34000 miles on it. Well, this car turned out to last much longer than expected. In fact, I kept it till it had over 200,000 on the odometer. I then sold it to a buddy that gutted it and ran hobby-stock at the local 1/4 mile asphalt roundy-round. I never, ever, not once, changed the oil. Ever. Added about a quart every 5000 miles or so. Never changed the filter. Granted, most of the miles were highway miles going back and forth 50 miles each way to school. My buddy did not change oil either, ran and won a few races, then plowed it into the wall. Who knows how long the engine would have gone.

When I got a different job about 45 miles from home a number of years later, I decided driving a 15 MPG GM Cutlas car was not going to cut it. I saw a brown 1986 Nisaan Sentra, 4 cyl, stick shift, no air, am/fm radio with about 40,000 miles on the clock. This car had brown outside, brown plastic seats, and a brown plastic "carpet". The owner sold it soo cheap, I figured the odo was rolled back. I just needed 40 mpg for a while till I could afford a car I could be seen in. Considered tinting the windows! Anyway, with no intent on keeping the car long, I again drove it to death. Changed a clutch once, a few brake jobs, tires, exhaust, timing belt, etc, but never changed the oil. Again, not ever, not even right after I bought it. At about 190,000 miles, the trans broke and only worked in a couple of gears. It went around 150,000 miles without an oil change, just an occasional top up with the cheapest oil I could buy. I gave it to a neighbor when I moved. Probably still running.

I bought a used Plymouth mini van because my wife said I needed one. I hate the thing. So I want it to go away. So I decided that it was luck with the Sentra and the Impala; I'll just say I change the oil in the van, but don't, and hopefully the thing will simply lock-up. Well, 6 years later, and no oil changes, the WPOS is still going strong. Pulled a camper trailer with it over the rockies with it (mostly in second gear and lotsa rpms), and a 17' drag boat back over the Rockies, again in second gear most of the way. Sucking some oil throught the valve stem seals at idle, but it did that when I bought it. Van had about 90k on her when I had to buy it, now has almost 200k. Still pull the drag boat with it.

So, tell me again why I have to change the oil so often in my current engines? I have hard experience that shows I don't have to change oil. This guy with the 27,000 miles on synthetic that had overheated bearings, maybe it was not oil related? Maybe he ran it low on oil? I've seen many many engines fail because of low oil, but have yet to see one fail from type of oil or length of oil change interval. Or because of an overheating condition in the cooling system, causing a breakdown of oil. As for severe service, cheap dino oil is what I used in my beaters. And I think I have severely overloaded the minivan. I hate that van but it sure has been good to me. A lot cheaper to run than a Benz!

This is hilarious!!

Has to be a troll. No sane person would listen to a word he says.

Must be a real pos camper and drag boat that you would risk towing it 5000 miles into the mountains with a van thats such a pos you wont even change oil.

This guy I knew was talking about two BMW diesels and a Mercedes diesel hed owned, how much a pos they were that they had valve trouble at less than 100K. Then I learned he was a 25K oil change Mobil1 nut.

I dont want to call Bravo Sierra on your claim, but its sounding like a whopper.

Dudes you do realize that until our newbie Wikkedpissa resurrected this thread the last post was made in March 2003? Nine years and ten months must be a record for longest undead thread.

ILUVMILS · #26 01-11-2013, 12:10 PM

I've changed the oil in my 124 about thirty times since this thread was started.

Holmesuser01 · #27 01-11-2013, 07:05 PM

This was an old thread years before I bought my car!!!

Mine gets 20w-50w every 3000 miles, and a filter, and mine is one of the goofy ones with the filter cartridge.

"Earlier today, I saw a failed engine on a Jeep Grand Cherokee that is interesting to consider. All the engine bearings failed. The bearing inserts saw high heat. They and the connecting rod caps are black. The crankshaft is ruined. It looks like the fix is a new long block. The engine was using a synthetic oil which starts with the letter A and is distributed by independent distributors. The owner had the idea that this fabulous synthetic oil is good for many, many thousands of miles of around-town driving with filter changes every 6 to 7 thousand miles. The oil had 27,000 miles on it at time of engine failure. The tech believes that the engine failure is directly related to the owner's failure to change oil on a regular basis."

even A's best oil isnt rated for more than 25k in non-severe service.....he probably had one of the cheaper formulas for not-so-extended drain interval, and thought "it doesnt matter" <------ very famous quote, u here this alot while discussing the topic of synthetic lubrication ....

here's one that mike (specialdelivery) and i always laugh about, caus this guy we know recommends this mystery crap.....lol......(new york accent) "If you put IXL in your........you dont even need motor oil.......DOESNT MATTER !" LMFAO "If your "A" stuff is so good, then why cant u drain it all out and drive to Sarasota.......DOESNT MATTER !" LOL LMFAO

EDIT: oh wow, i didnt even notice how old the thread was.......oh well the facts still stand....

(disclaimer) (I have used "A's" diesel oil in my 2 diesels, for over 200k miles combined, over 11 years, driving many many deliveries......i do every 15k on the diesel oil.....filter every 5, its awesome...

old engines require ZDDP additive .Do the newer oils have thator just the diesel oils?
