I will check it weekly when I first buy it.
Once i figure out if it actually uses any oil I may adjust what I do.
I always liked the way most Renaults since the 80's have an oil level check every time you start the engine, and it is accurate.
Checking the oil on the Smart is a pain in the you know what, empty the boot, remove the parcel shelf, remove the sound deadening, undo the screws that hold down the boot floor and then struggle to get hold of the slightly awkwardly situated dipstick.
Annoyingly the Smart is based on a Renault Twingo and I wonder if the Twingo has the usual oil level check on the dash every time you start the car.
Preferable to the nightmare of the Smart.
