Time for an oil and filter change...I measure I have 2.3 litres left from last March's oil. So as capacity is 7.1 litres I can only buy one 5L pack this year . Will get to the same MB spec again but assume I can mix totally different brands of oils in this way?
I notice that in winter months the car uses hardly any oil (less than a quarter of a litre for over 5000 miles), however in summer (35 degrees plus ambient temp) after long motorway trips/ particularly including long windy mountain climbs the car can use up to half a litre every 3,000 miles. Should I increase viscosity (currently use 10W40) and if so can I mix viscocity e.g, 5L of 10W50 and 2L of old 10W40?
I don't really mind topping it up, although the rather bright oil warning light comes on at just under half, and usually decides to do that at the start of a long night drive thus being exceptionally annoying so if it uses less oil then all the better ... I remember starting the long night drive through France once where there's no street lights and 5 miles in the oil light flickers on. Was so bright/annoying I stopped, waited for it to cool a bit and added oil, only to use the washers 5 miles later and then the windscreen washer light came on (this also comes on when the bottle is not far under half full)
