Choosing the right type of oil
Use only oils approved by smart gmbh
(acc. to MB sheet 229.5). The MB sheet
number is marked on the oil containers. A
list of the approved engine oils can be
obtained from any smart center or
smart service.
>Important!
Do not use special additives. They may
lead to increased wear or engine damage.
A qualified specialist workshop such as a
smart center will be able to provide fur
ther details.
Engine oil viscosity
The SAE class (viscosity) has to be chosen
in accordance with the average outside
air temperature for each current season.
Exact adherence to the SAE classes ac
cording to the outside temperatures
would, however, necessitate frequent oil
changes. The temperature limits for the
SAE classes therefore should be viewed as
guidelines which can be temporarily ex
ceeded or undercut.
Oil level
Environment!
When topping up the oil, take
care not to spill any. Oil must not be
allowed to escape into the soil or wa
terways. You would otherwise be damag
ing the environment.
