As a former Shell employee for most of my career, and a current owner of an SL500, PLEASE DON'T USE ROTELLA T 15W-40 in your Mercedes.
Shell's Rotella T is a wonderful product for non-catalytic exhaust applications. I use it in my Kubota's front-end loader / backhoe, and in my lawn tractors.
However, using Rotella T in your M-B will plug up your catalyst bed, causing reduced performance and big $$$ to replace the catalytic converter.
The best oil you should be using is MOBIL 1- Full Synthetic, High Mileage 10W-40....... that's correct, you are hearing this from a Shell man!
This particular MOBIL 1 oil contains extra anti-wear additives for added protection, and seal conditioner to help prevent leaks and reduce oil consumption. It's also the recommended oil by M-B for the older SL-series engines.
It's also fairly cheap to buy...... I buy it at WalMart for $24.97 for a 5-quart jug.
Pic is attached should you wish to use this particular type of Mobil 1.
Hope this helps. God Bless, Arctic.
