Dessert Menu: OM642 = "The Pudding Maker"

This is NOT necessarily a knock on the OM642 engine (no pun intended). It's a PSA on what happens if the wrong oil is used and/or if someone tries to be penny-wise and dollar-foolish when it comes to trying to do extended oil change intervals.

It's a long video; you may want to watch it at 1.25x or 1.5x speed. Go grab a can of whipped cream and enjoy...

Thanks for link. I wish he had mentioned the condition of the rings.

This is why I stick with the m112s over this nonsense. All the fuel economy in the world doesn't make up for the Kafkaesque complexity and expense of maintaining one of these egr choked "modern" diesels.

I would guess that engine had not had an oil change in tens of thousands of miles, regardless of the oil used.

I have an early OM642 in my motor home and it does just fine...and its moving ~11,000lbs !

The one in my dad's 2013 ML350 is also a beast. Moves that 5,000lb SUV completely effortlessly.

The M112 is a great engine, but it is very thirsty compared to a Bluetec diesel. At higher fuel costs that adds up fast! They can also develop lifter ticking at higher miles....mine is starting to do it now around 162k....and my bro and dad's both did it too.

I can drive my GLK (equally fast...heavier, more capable, more comfortable) for about 1000 miles for $104 at current diesel prices.

The same in my E320 wagon would cost $210....and thats being generous. Most of the time around the city when I use it I am getting about 14-16mpg. My GLK does 29-30.

$100+ saved every 1,000 miles of driving, even more if doing all freeway with the diesels....I saw as high as 39.5mpg on a 100 mile trip last week!

Weird.
My E320 is costing me 15.8 cents per mile ($158/1000 miles). And that's on California gas. My lifters are dead quiet at 178k and 194k miles (2 cars). Maybe you should get those lifters replaced, it might improve your fuel economy. Have you checked your oil pressure?
Looking at my fuel records, the E320 has never dropped below 17.3 MPG. If your E320 getting 14-16 MPG something's not right.

Premium around here averages ~$3.75 currently, though I no longer use it in the E320, went down to 89 and it made no difference.

In ideal/best conditions like freeway cruising it will do about 23.5mpg or so. Driving very frugal in the city might get close to 17.5-18. I don't drive that way.

I think we're talking about different generation E320s. The 04 wagon is substantially more fuel efficient despite having the same engine. I run mine on 87 octane except when towing in the summer.
