Given the model year, if you want an oil with MB approval you'll need a 229.5 or 229.3-listed oil.
A VOA for the Mobil 1 10W-40 HM is
here.
FWIW, I've been using the Mobil 1 10W-40 HM in a 1995 E320 that I purchased last year with a minor oil leak (I think front timing cover, based on where I would see oil on the pavement). I've got 12,700 miles on the oil, although it isn't really fair to call it a, "change interval" ... I've been incrementally removing some used oil and adding fresh oil to put fresh additives into the oil.
Somewhere in the last 3,000 miles, the oil leak stopped. Full disclosure, I also had the timing chain tensioner replaced during this time, when my mechanic realized its internal ratchet mechanism was broken. He didn't call it out as leaking oil, but since it is oil-pressure driven, I suppose it could have been involved. Anyhow, either the repair or the chemistry in the HM oil seems to have fixed my leak.
On cold morning starts last winter I was hearing either some lifter rattle or the timing chain slapping around until things reached pressure. My fall oil change will be to the Shell Rotella T6.
So we have one vote for M1 10W-40 HM instead of 0W-40 ...
How else did the car act on that Oil?
Its also refreshing to know that this Benz doesnt need a 50 as its high Weight.
0W-40 was my first guess, too.
If M1 HM 10W-40 STOPPED a leak, seems that may be the car's good Oil. I always thought you could go a ittle higher on the "W" number. (Example: Car secs a 5, can go to 10. Vice-verse, car specs a 10, you can go to a 5, or 0.)
Now. S500 at Jiffy Lube..
