Just like the thread title says, why do they take ~8 as compared to our ~4.5qt?
My friend has a c240 and has to buy 8qt of 0w-30 which comes out to around 70 bucks.
His engine's compression is 10.5:1 (2.6L) compared to our 10:1 (3.5L)

So why do they need so much more?
Yeah 8 to 8.5 quarts is the norm for the 99-05 C240, very large oil sump and oil cooler is why they hold so much oil.
Compression ratio has nothing to do with oil capacity.

Better cooling
Less contamination (1g of fuel will contaminate 4.5 quarts almost twice as much as it will 8 quarts)
Bigger crankcase (I6 has a bigger oil pan footprint than a V6)
More awesome (because they are)

Yeah, but what is the purpose for designing it with a larger oil sump?
My friends car isn't high performance per say (160hp?) And the high end companies aren't stupid wasting extra money on 4 extra qt of full synth oil... so why did they do it? Would it allow the engine to run smoother?

So they can have those 8-10K service intervals? More oil get dirty slower I would assume.
Because 80% of their owners are dumber than bricks.

yeah, but if nissan used mobil 1 full synth [4.5qt] from the factory, our change interval would also be ~15k miles...
I understand more oil will have to be changed less often, but good oil (w. good filter) is also changed less often.
So why not use the mobil synth and have it be a normal amount of oil?
Because it's not needed and implies higher cost of maintenance (as well as creates more production cost for the manufacturer) by making the maker have to justify synthetic oil as a factory fill. Keep in mind there are NVH benefits to having that much oil too.

Tear apart an S65 and tell me oil capacity is only used for extended maintenance intervals
Considering the amount of oil it holds it's OCI's are a hell of a lot longer than they otherwise would be considering it uses an oil life monitor.... Also this topic deals with more casual people movers that don't have the performance pedigree to warrant large oil capacities like the S65. Nice try though.
Back to bed with you.

Sure because 100,000rpm turbochargers on the N54 will spin with cat piss flowing threw them. I imagine the N54 is still too "performance" oriented for what you had in mind, despite it being used in every people mover they make. No you probably had the N52 in mind, no turbochargers, no 8300rpm, no F1 engine block, just a couple VANOS units and a valvetronic system, sodium silicate does the trick. Yep, the only reason BMW uses more than 4.5 quarts is for when your wife forgets the "casual people mover" with the bearing clearances and valvetrain of a 70's big block needs new 710.

Tell me another story.
Go soak your head already. Unless it is a high performance engine that needs that additional thermal sink of the extra gallon of oil in its system it is only going to serve for extending maintenance intervals.
Go ride BMW's nuts in some other thread.

jus to add my .02 cents...like mentioned before maybe the excess oil capacity is a fail safe measure for idiotic drivers...do you think the averagr benz owner checks his dipstick regularly...hell the average camry owner doesnt. so maybe the excess oil capacity is just in case oil is not consistantly monitored there will always be more than enough there to make sure no major problems come up from having lack of oil. thats my thought since these euro luxo brands like to give owners the misconception that these cars are absolutely perfect and nothing can go wronger ever
other than that the extended service intervals make sense too... owners of these cars dont want to be at the dealer getting service done, they want to be out driving their cars lol.

Well, the newer BMWs and Merc' have a sensor which checks the resistivity of oil and can tell when an oil change is necessary. So the average bmw/merc owner sees the light on the dash and takes it to get it changed....
I'm not a fan of either motor, giving examples of the thoughtlessness of his statement.
Your petty argument is the only thing thoughtless in this thread. Sorry you are so thin skinned. I'll try to keep that in mind if I ever decide to imply criticism of anything BMW related.
