Checking the quality and level of oil (Hyundai Tucson LM)

1. Check the oil for deterioration of its properties, presence of water, color change. If the quality has deteriorated, replace the oil.

2. Start the engine and let it run for five minutes. Turn off the engine. Then check the oil level. The level should be between the "L" and "F" marks on the dipstick. If the level is below the "L" mark, check the system for leaks and add oil up to the "F" mark.

Note: Do not fill oil above the "F" mark.
