Engine Oil and Filter Replacement

Model: Smart Smart 450 - Years 1998-2007
Part: Engine oil

Replacing the engine oil and the corresponding filter is a very simple maintenance task that does not require special recommendations other than properly disposing of the used oil. Access the rear of the vehicle where the engine is located and position a container under the oil sump (the filter is located directly above the sump). Unscrew the drain plug (the plug includes a filter) located on the side of the sump to drain the used oil and the filter. Clean the filter present in the plug and screw it back in, then also screw in the new filter after coating the gasket with clean oil. Finally, fill the engine with new oil until it reaches the maximum level.
