Why is there such a difference in power between the older diesels and the present day ones, particularly in torque? The engine capacities are very similar at around 3 liters.

I checked out my engine bay and there is very little room.

Goatman

The king didn't have anything to do with that? I'm shocked..... Then again, that one runs....



Very simple, improved intake and exhaust design along with computer controlled everything and better turbo's...

Goatman

Flushed and filled the power steering system last week with Amsoil.


Just the engine oil flush and fill to go!

Its the progress of technology. Computer aided design allows precise combustion/swirl control, more valves improve airflow flow, high pressure common rail injection improves atomization, computer control improves operating precision and (most importantly) CDI engines are direct injection which accounts for 15% efficiency and power.

This was the king's response before he edited it:

In short, he's not ignoring me, he copied and pasted my answer......

Goatman

Well, the car god smiled on Massachusetts today after dropping 2' of snow down on us last weekend, its all gone!!!!


50 degrees this morning and I finally got around to FLUSHING the engine oil with Amsoil engine flush and then refilling with Amsoil Heavy Duty 5w/40 Synthetic. I actually got 9+ quarts out of the drain, which I attribute almost exclusively to adding the Amsoil engine flush and idling for 20 minutes.


Going to my sister in laws which is about an hour away in a few minutes. Will let you all know how she performs after we come back!

Goatman

Car runs great, as usual. Seems quieter to me, but the wife didn't seem to think so. Who knows..


Anyway, I'll be trying to gauge the mileage if I can, but I don't drive the car that much with my work truck being, well, free..


I'll see my next oil filter at 12,500 miles and the next oil change next December! Gotta love it!

Goatman

For all of you that have PM'd e about the results of the Amsoil mileage improvements, I finally have a decent result for you. My wife made a two hour round trip Saturday, then her and I used the car about 3 hours on Sunday, as well as running errand, etc.


We pulled excatly 26 mpg out of it! 70-80mph on the highway, I idled it for about 10 minutes while waiting for my wife in a store one day as well. Plus the normal stop and go BS.


That's a solid 1-1.5+ mpg improvement! Not too shabby!

harkgar

Hey Goatman,

26 mpg is mighty good for a W126! My sold 560 SEL never went beyond 15 mpg no matter how slowly I was driving it.

Goatman

No doubt. I hope it continues!



The real test will be the road trip to Florida the wife and I are taking in February.

Goatman

Leaving for the looooong trip to Fla tomorrow night with the wife, mother in law, and my Dad. All piled in the SDL with the dog, of course.


Will the Amsoil lubed SDL hold up to the 3000 mile test? Will the mileage best of 26mpg be beat?

Got the cruise fixed, along with a nasty fuel leak from the #1 and #2 pre chamber seals. What a nightmare that was.


Stay tuned sports fans.

TMAllison

Best not forget a couple of gal jugs of oil too.

Rob CL

Good luck with your testing.

I am personally, not convinced of AMSOIL's claim of superiority. I find that Lucas oil products work just as well and are available in storefronts.

Goatman

I have 9 quarts of oil in the trunk. Shoudl theoretically burn through 6 up and back. A couple of quarts of PS fluid and trans as well. Plus a bunch of tools, jack, etc..


Amsoil can be found in stores if you look. Just not as common.

harkgar

Goatman: if Amsoil is so good why is your engine still consuming so much oil? 6 quarts for a return trip cannot be normal. I used to drive down from Toronto to North Carolina (Durham) and North Florida frequently in my wife's sold half ton Suburban and the old small block burnt very little oil, not even a liter.

Secondly, why risk doing harm to your MB engine? Surely the oils they recommend cannot do harm to their engines.

Have a nice trip.

Goatman

Not aware any oil has stop leak in it... Nice swingandamiss though...

240D 3.0T

I hate to burst your bubble goatboy, but one quart in 600 miles of driving is significant. Maximum oil consumption listed by Mercedes is .8 liters for every 1,000k.

Even my engine with more than 350K miles only goes through 1 gallon per year (8-10k miles).

Untertürkheim

Are you using the 15w-40 (with MB passenger car approval) or 5w-40 low SAPS (without MB approval)?

TMAllison

Thats pretty tight; is it more-so consumption or leakage?

My 606 at 257k uses one make-up qt per 16k mile oil change.

G'man prob will reach 25k miles on his oil and test out ok because he will have added more than 40 qts of makeup oil to the original 8 along the way.....dino oil would prob test out ok at that rate.

harkgar

Good point Unterturkheim. 15W40 was recommended for my sold 560 SEL too. For the last few years of ownership I switched over to full synthetic. I feel that the oil leakage was due partly to aging gaskets and a easier flowing oil.

Goatman

Made it down with NO problems what so ever.

Average mpg with 4 adults, one dog, and all the luggage: 25mpg

Average speed: 75mph

Oil consumption in 1500 miles: nearly 0, maybe 1/4 of a quart.

Don't understand it, nor do I care. Just lovin' every minute!


Also digging the $1.99 fill ups in Va and NC.




Looks like Goatboy wins again.

Goatman

Just made it back!



Green Anti-freeze and all.. Car ran flawlessly the entire way, MPG averages were about the same, we were going a bit faster; with the A/C on when leaving Fla., but everything worked out to about 24-25 MPG on average!


$1.98 diesel in VA. rocks!


I have one small fuel leak that sprang up on us about half way home near the injection pump fuel lines, but other than that and possibly an oil change, the car is unscathed!


3000 miles, 25 MPG with four adults and a dog for $3000!

Untertürkheim

I am running 229.5 spec Valvoline Synpower 5w-40 in my 560SEC, no measurable consumption (or leaks) between 5k mile changes.

Goatman

Got the fuel leak fixed today with a simple gasket change at the junctions of the two intakes.. The mechanic conspicuously put it back together without one.

I find it curious that fuel can make its way UP the intake to the junction. Opposite the air flow path. Will have to look into that.

6,000 miles down, 19,000 to the next oil change.
