I use Mobil 1 ESP Formula 5W30 and I buy it at AV Lubricants.

How often should the oil be changed in a 35d?

Dealer says every 10k miles but i do it every 7500, some people do it around 5000. I think 7500 is a save bet, thats what im going with in my 35d.
I used Pennzoil Euro L 5w30.

Just changed from the last of my cases of BMW SLX/OE oils to...

Mobil 1 ESP 5w-30; BMW OE filters

roughly 7k intervals

Just did an oil change on my 8/2011 35d. The oil filter canister lid is 32mm. I couldn't get 1 1/4" socket on there but I had a 32mm one kicking around for some reason.

Oil level was right below the MAX mark on the dipstick before the drain with oil temperature around 81-84C. The oil level page on the iDrive monitor was at MAX.

I pit a little less than 7 Liters of oil back in. With oil temperature around 75-78 and after about eight miles of driving, oil level was below the MAX line around 7/8 and the iDrive displayed a level representative of that level. I will continue checking it.

Drained Mobil 1 ESP 5W30 and put in BMW TwinPower Turbo 5W30. Before these I used the Castrol EDGE Professional OE 5W30.

Same here, I think bmw techs do not have the time to wait for the old oil to drain completely so they maybe put the screw back on while its still dripping.

at 8 quarts i am still 2/3rds of the way from max

Are we sure we’re not confusing quarts with liters (8 quarts = 7.57 liters)?

FWIW my most recent oil change came in liter containers.

I pured 2 gallons of Rotella t6

so that's 8 quarts

unless the container of rotella I poured in came in slighlty low?

7.0+ liters every time. I open the fill cap and pull the filter before draining the sump. I let it drain for over 30 minutes or close to an hour if I'm in no rush.

6.5 liters in, let it warm up a little, drive around the block and then check. Usually it's 1/2 to 3/4 on the dipstick. I add the rest of the liter bottle and then drive it. Check again and 90% of the time I need to add another 0.5 liter.

To check the dipstick, I use the same method I use for my E39 M5 because I know no better. Maybe that's wrong.

The Mobil 1 ESP 5W30 comes in liter bottles.

While looking for Valvoline 5W40 MST at my local WM (Raleigh, NC), I stumbled across Penzoil Platinum Euro L 5w30 (LL-04 and MB 229.51 approved oil). Best part it was in stock and $22 for 5 Qt jug.

Valvoline MST is usually $6.98/qt, but never available in store. I usually order on line and pick up the same day.
