MBZ SLK
My SLK is my weekend car, and usually don't get much attention in the winter. I drive less than 4,000/yr so I try to change oil/filter once a year. Mobil 1 oil is what is recommended from the factory, not sure about the filter.

In my C43 AMG, Mobil 1 oil, no idea what kind of filter (I feel bad now), changed ever 5K - - overkill, though.
I'll do the same with the SLK. Can't change the oil too much, I sleep better at night. New filter each time. Clean air filter 1-2x per year.

Wyatt. I read an article from 6speedonline(porsches) that said changing the oil too much actually INCREASES engine wear. that once the oil has broken down a little it provides the best protection. That oils now aday are so advanced you can wait longer but that he was concerned with the decrease in Zinc and phoshates in the newer oils. That boron is being used to replace some of the zinc...He said every 7-10,000 miles was best with synthetic. and he rued the day that he went away away from normal, parraffin based oils(the best are from pennsylvania)...he said mobil 1 oil filters are amongst the best. I can't remember if he said he changes his filter every oil change or every other. i guess every change couldn't hurt at all.

Here you go Wyatt.

got from 6speedonline. 997 forum. page 4. "The reason for 10,000 over 20,000 mile oil changes". they get into it. it's an interesting forum.
he is referencing porsche but i'm sure it applies to M.B.'s.
Please tell me what you think..

Also, be wary of the article you posted - it centers on air cooled powerplants (ie Porsche), not water cooled powerplants (which have different thermal properties & cooling requirements based on different operating temps & oil dispersion & filtration set ups.....AMG filters, for example, are fabric for increased filtration over std dual pass oil filter designs).

Thanks for your reply. I have never heard of Royal Purple before. Has anyone else here heard of it or used it?......I checked out R.P. website. It sounds good. I'm surprised I haven't seen an ad or heard any enthusiast mention them. Auto stores sell it but do any MB dealerships or certified MB shops use it I wonder.

I run Mobile 1, and I do the oil changes every service interval, i.e. about 10k miles (15-16k km's). Honestly, I think I'll have parted my ways with the car waaaay before it gets to the point where it wouldn't run anymore, so I don't care to do oil changes every 5k miles or something like that...
I most likely won't have the car ten years from now with 200k km's, and modern cars should be able to last that many just fine. Back when bits and pieces were not machines to perfection, some cars required engine rebuilds after just 60k miles, but we now hear of cars frequently lasting hundred and hudreds of thousands of miles just by following standard services.
Of course, if you're the kind who WILL drive the car for several hundred thousand miles, then extra care can be taken.

Good point. I'll probably begin the 10K intervals.
Royal Purple is great. I have heard amazing thing about their syncromesh transmission fluid.
Also Redline, heard great things about their differential fluid.
I'd stick with Mobil 1 for the engine, though.

Yellow. do you have the P30 package on your SLK? If not, was that a choice?
thanks
Wyatt...Royal Purple recommends the Max-ATF for mercedes tranny fluid.

I'm sure their Max ATF is great in our cars, but never used it before.
