Been doing oil changes on all my cars for the past 10 years... but this is the first time I've purchased a luxury car. Planning to take it to the stealership for the first oil change or two, but would like to do them myself later. Problem is, I can't find any info online about this brand new model, nor the MB 229.71 oil spec or oil filters. Hard to find oil meeting this spec here in the USA. Thanks.
