What is a good oil change interval with a pure synthetic like > Mobile 1? I mainly look at the colour of the oil. These days I do a lot of motorway driving which is less demanding. I use the cheaper Halfords 5W40 fully synt and change at 4k miles. Then I use Shell Optimax petrol which I believe is good for the engine.
