Preferred oil?

What is the ideal oil to use in my E320?

Yes, I know it's kind of a stupid question, but I want to be sure I'm using the correct oil.

Mobile-1 15w50 synthetic is what I run in all my w124's. Until recently it had a very high ZDDP content which is good for our motors, it is still higher than most other oils. If your making the switch then run it for a few thousand and change it because it will pull a lot of crap out of your engine. I wouldn't worry about it damaging anything like on American cars because the Germans believe in actually filtering their oil.....I haven't had any problems at all with it. I think the cars actually run better. Just FYI synthetics tend to leak more than dyno oil.

More info on different oils can be found here, but be prepared to read :P

My manual says 15w40 or 15w50 for all year oil, so I'll go with that.
Will it have any negative effects if it's ran with like 5w30 much of its life?

Oh God, not the never-ending oil thread, again! LOL

Seriously, those oil discussions on Ecstasy leave nothing out and it is something that everyone wants to know about, at some point.

I think the previous owenr said he only used Mobil 1, so I should probably use the same brand...

1992 300TE 4matic wagon
Preferred oil?

Trying to avoid the pitfalls and quagmire of "what type of oil?" discussions....I've always been a proponent of Mobil 1. However, their early product was loaded with PCB's and I don't even want to think how much of that stuff touched my skin. In the last three of four yrs in every independent synthetic oil test that I've seen, Amsoil has a slight lead over Mobil 1, in every category.

Problem with Amsoil has always been their dealer sell network and hence the way they market their product-but it's a great product nevertheless. Now, it's showing up in auto stores across America, albeit at whoring prices. My wagon has too many miles on it to go with anyone's synthetic however, as their lubricity & viscous properties tend to make the stuff seek any opportunity to vacate my engine and live elsewhere.

On the rebuild, I'm breaking in the rings with dino and then going Amsoil. You might find some exotic synthetic oil as good, but not better. No, I'm not a Amsoil dealer, never will be one and always hated their sales approach-one step away from 'pyramid sell'.

Castrol GTX 10w 30. I used castrol syntec 10w 30 for a while but I don't think synthetic is good for our cars, not to mention it leaks much more than conventional oil.

In my old diesel I ran 20w 50....
