Hi Guys

which would be better for my standard 2015 c200.

a - genuine merc oil from dealers

or

b - a decent aftermarket oil like millers?

i was a webchat from one of the friendly guys at opie oils and they said - "Aftermarket oils from quality companies will exceed the minimum requirements for the specifications, whereas own brand oils will meet, rather than exceed the spec"

what do you guys use?
 
ive just ordered genuine filters, spark plugs and oil from MB newcastle's ebay page but i just wondered what would be better. the actual genuine oil from merc which meets the specs or aftermarket like the millers performance oil which exceeds the specs. just wondered what you guys are using.

Mb don't make oil. Anything made to mb standard requirements is good enough .
 
Try Smith and allan and look up the spec.

I found a while back that Asda's fully synthetic oil meets the latest MB standards ( it says so on the bottle ) and I've been using it ever since .


I could only see the 2L bottle listed on Asda's website , but they usually have it in 4L bottles if you go to your local branch , the other variants are all priced at £22 for 4 litres , and I've ran my SL , my S-Class and now my W124 on it for years .


The ASDA BMW branded fully synthetic oil meets MB specs up to 229.52 and is £22 for 4L

no, fuchs, millers and liqui-moly were recommended to me by some subaru specialists when i was in leicester. richard henry motorsports (impreza specialists in bradford) and scooby world recommend millers.

When I went to my local merchants for oil ,they only had one bottle of Fuchs left , I wanted two ,because my car uses 8 litres , the parts guy said he couldn't give two Fuchs. So I went on eBay and bought shell helix.ive used it ever since.

I hope you replied Fuch you as you left !
 
I would quite happily use and have used any oil that is approved to the correct MB spec.

If anyone needs persuading that the "genuine MB oil" is nothing special then consider the relatively low price it sells for or at least did sell for. It's 5 years years ago or more now but the last 20L drum I bought off ebay was £42 and I assume they didn't make a loss on it. The really high quality oils, particularly the tue synthetics are much more expensive than that.

I'm not suggesting there is anything wrong with the "genuine MB oil" but neither is there any reason to put it on a pedestal. Buy anything that is MB approved to the correct spec for your engine.
 
A high performance model like a C63 etc , probably, a 2015 dirty diesel c220,I'd say not .
Which one would benefit more from a low volatility long-life oil? The one with the constant EGR problems. That'll be the diesel then.

You'd simply buy a suitable oil for that , it wouldn't necessarily be a high grade oil that costs fortunes. I've been using mannol low saps c3 in my cars for 10 years . 20 litres costs £50 . Hardly high spec which the question was .
