The oil level should be checked each time you refuel. Be sure the oil level is maintained between the upper and lower marks on the dipstick.
Low oil level can cause internal damage to the engine and overfilling can result in high oil consumption. The distance between the dipstick
marks represents approx. 1 US qt (1 liter) of oil.
