Hi all, I want to treat car to a really good quality oil change. Have searched all the oil checkers, and there seems to be a lot of variation in suggestions.. from 0/40 to 5/30 synthetic. Any suggestion as to which make and grade would be best? Sitting at 115,000. Many thanks

Use midrange recommendation in yr owners /guide. And if u want to "treat"yr motor do changes at half intervals .

No it’s the older (And more reliable) OM605
I wouldn’t be using a really thin oil in it. 10/40 is what I’d be looking for

So would you say there is any advantage to spending money on the likes of castrol edge, or is that just a waste of money!

As per above just change it twice as often if you want to look after the engine

On paper a waste of money if your going to only drive half of the amount of miles, look at a 20 litre bag in box mercedes oil on ebay , or shell helix . If your doing 6 month oil changes.

The difference is how “thin” it is at low temperatures.
With modern right tolerance high performance engines the lower (0W) is required. Your 1999 engine does not require such an oil and will use oil so you’ll end up tipping the oil up as the engine burns it as it’s not made to the same tolerances.
0w-40 is also a lot more expensive and you’d be much better served buying 10w-40 and changing twice as often.

A 10W40 is more commonly found as a lesser semi synthetic and 5W40 a fully synthetic with all it's benefits .


0W30 to 5W40 is actually listed by Fuchs and 5W40 to 10W40 by Opie Oils , somewhere in the middle of everything is good .

Go 5W40 fully synthetic .

My w124 has been using mobile 1 from day 1 till today as the recommended oil. Still does today and doesnt use a drop and engine is clean as a whistle. depends on the condition of engine re oil usage.

Very interesting.
Nobody mentioned an engine oil flush as a treat for the engine. Any views.
