Engine oil
Checking engine oil level
The engine can seize if theoil level is low, and this canlead to accidents.
Always make sure that the oillevel is correct.
The oil level varies with thetemperature of the oil. Thehigher the temperature, the high-er the level of oil in the sump.Checking the oil level with theengine cold or after no more thana short ride will lead to misinter-pretation; this in turn, means thatthe engine will be operated withthe incorrect quantity of oil.
In order to ensure that the en-gine oil level is read correctly,check the oil level only after alengthy trip.
