Need advice
I change every 3-4k miles because I own my car and will drive it until it explodes.
The dealer charges $90 per oil change and uses Castrol Synthetic.

There's a link somewhere on these boards with pics of how to change the oil on a MB V8 engine.
you should at the very least change your oil once a year. my mother has a 99 E430 she never uses. it only has 4300 miles on it and i drop the oil once a year(Mobil 1!!!!). i was reluctant at first but the manual recommended it. with the new factory provided service maybe it won't be stated in newer manuals...cost savings for MB corporate!!!!
also....acids that are suspended in the oil from the combustion process are not removed by the oil filter and these acids will remain trapped in the oil. i would use full synthetic oil. it's just a little bit better than natural based lubricants in protecting your engine but hey...it's a benz right!! as for the oil plug...i have yet to change the oil on my S55 but the 00 E430 i owned the oil plug was....just....an oil plug. i for one have never had much faith in the topside method. it makes it easier but i have to believe that gravity will do a better job removing anything nasty that might be laying in the oil pan. also..as for the MB in dash service indicators...i just don't feel comfortable leaving oil in for 10000 miles. the fact that these autos are designed with a larger oil capacity still doesn't win me over. i drop mine every 5000 and use mobil 1. when i get to the 10000 miles mark i let MB change the oil during the scheduled service interval(they also use Mobil 1). well.....that's my two cents worth.
good luck.
