That would be disappointing, because we've bought cars from them before and my sister has her Land Rover usually serviced there. But your guess is as good as mine to be honest. As we discussed, the manual does say that the car would use up around 1l of oil per 1000km if driven at higher speeds. Given that I usually drive it at 70mph plus as I only really go between London and Kent, using up 1l wouldn't surprise me. Let's see how the next 1000km are like.My guess is that the dealer put the minimum amount of oil that they could get away with at the service and now the car has used 100-200ml in the last 1,000 miles and that has triggered the message. My bet is that you won't see the message again ......until after the next service!
I bought two 5l from Mercedes online. It can be used when the car then needs an oil change. Price-wise it wasn't bad at all. As mentioned, I wasn't initially sure if maybe it needed an oil change, was just the case of needing a little top up or maybe the sensor failing. I haven't had the chance to drive it very much during lockdown as I work in the hospital, so when the light came on, I imagined the worst.Why 10 litres of high performance MB AMG oil 229.5 at home?
