Oil Smoke, 2006 S65
Searched the archives and found a few comments about oil consumption. Car has 13K miles and I'm beginning to see oil smoke, sometimes a little, sometimes a cloud on startup. I've added a couple of qts in the last 3K miles, and the car is going to the dealer later this week. Any body have any official feedback from MB about the oil use of these cars? My 04E55 never burned a drop, but that driving experience did not begin to compare with this rocketship.
Cheers,

Nothing to comment on the oil burning but curious as to your comment about the difference in the two cars. The 65 is that much better than the 55? I ask because I would like to get a S65 at some point myself and used to have an 05 E55.

I don't know about "better," but it's certainly different. The torque at any RPM provides a very different driving experience. Feather it at any speed and it responds. The V12 smoothness also has to be experienced to be appreciated. The car pulls from idle to redline with no vibration. It's uncanny.

The other plus is the inside of the S65 is great. Real leather on the panels, dash, and console. The S has lots of room, first car I’ve ever had where I don’t set the driver’s seat all the way back to drive. Lots of leg room in back, lots of space in the trunk. On the weekend trip we put about 650 miles on the car, averaged 71 MPH on a mix of country, town and interstate roads and the trip computer reported 20.5 MPG.
Do I need the Twin Turbo V12? No, but I’m sure glad I have it.

All 65s burn some oil. The oil spray cooling of the cylinders accounts for some, by design. I burn about a quart per 2,000 miles. AMG (at the Private Lounge) says this is normal. Also, my service advisor told me that they burn from 1 quart per 1,500 to 2,500. He told me that when I told him I was thinking of trading in my S55, so he had no reason not to be honest. In fact, he did it because it was a customer satisfaction problem for some of his other 65 customers. I just keep a quart in the velcro tie down in the trunk.

I had an 2006 S65 that would belch smoke upon start-up. Along with everyone else, this is normal.
It set off my smoke alarm in my garage once.

No obvious sign of problems. They did get a little smoke on start up a couple of times. We are now engaged in a full blown oil consumption test. Car was filled with oil, then fully drained. Oil was weighted (?) and then put back in the car. Now I drive it until (if) the "put oil in at the next stop" light comes and then the car goes back to the dealer, where the oil is drained and weighed and examined.
We will see.

its normal for a turbocharged car to burn oil, when you shut off the car the turbo is still spinning and with no oil circulation due to the car being off that little bit of oil gets burnt up while the turbine is winning down. when you park let it run for a bit to slow the turbo down and keep oil circulation, this will reduce the little bit thats burnt. mine was burning up oil like crazy on 0W-40, (recommended oil) i switched to 5W-30 and the oil burning stopped. thicker oil is better especially for turbo cars

Mastertrust, what grade of oil are you using? AMG dont' recommend any 30W grade oils for their cars - just 40W. They say the engines need the better high temp shear strength. Don't think the low temp viscosity is so important. Maybe try a 5W-40?
I can't see that a 13k mile car will have worn turbos. Mine did more than ten times that with no problems, and the exhaust had virtually zero unburnt hydrocarbons when last tested.
In general, turbos don't normally leak oil like engines do. They do have seals, but not in the usual sense. They stop pressurized exhaust gas from going inwards into the turbo bearing housing, they don't stop oil going outwards. Oil is controlled with a centrifugal spinning disc in front of the shaft seal, and it all drains away under gravity.
The V12TT also has water cooled turbos with a run-on electric pump, so the turbos are still cooled after shut-down. They have two journal bearings, not one, and they have two hot shaft seals, not one. The same basic turbo is also used on lots of mega-mile commercial vehicles; its a very robust and durable installation. Just don't go cheap with oil changes.
I'll be interested to hear what your dealer finds.

You're right there, that's the EGR pump.
The turbo cooling pump will be pretty small - the feed pipes are only 8mm ID. In fact, I'm not so sure any more that there is a separate pump.
The M275 training document says the cooling feed is at the bottom and the return at the top.
The bottom pipe simply connects to the block, which is pressurized by the main engine pump.
I did read somewhere that there was an electric pump, and I just assumed that was right. So I'd have to say I don't know, and I apologize for the bad information.
