I've read a lot in other performance car forums that you get better performance and a smoother, quieter engine by changing from regular mineral oil to synthetic oil at your first service, and every scheduled oil change thereafter.

I used to prescribe to this phylosophy when I had my Honda S2000 - but that engine was frequently maxing out at 9000 rpm, so synthetic could have been more beneficial for such a high revving engine.

I just wonder if anyone has any guidance on whether synthetic oil is a benefit (or even necessary) for the SLK, or will just be an extra drain on my checkbook.

MB recommend the use of synthetic oil for the R171, namely Mobil 1

you should not be using a mineral oil with this car.

My dealer says my car came with the synthetic oil not mineral oil and I have been using the Mobil 1 SYN for European cars 0-40W.
