The engine oil in a Hyundai Tucson acts to lubricate the internal components of the engine to prevent them from seizing. The manufacturer recommends changing the oil every 3,000 to 5,000 miles depending on driving conditions. An extreme upper limit of 10,000 miles between oil changes is rarely acceptable. This is because engine oil breaks down over time due to the heat generated inside the engine. While the oil does help to control the friction of the internal components--and thus the heat--it is unavoidable that some heat will be generated and that this heat will work to degrade the oil.
Jack up the front of the Tucson using the floor jack. Place the jack underneath the front jack point and lift the vehicle off the ground.
Place a jack stand under each of the front pinch welds and lower the Tucson onto the stands.
Climb under the vehicle and place the oil catch pan under the oil pan.
Remove the oil drain bolt from the oil pan and allow the oil to drain out.
Remove the oil filter. The filter is located directly above the oil pan and is screwed into the engine block. Turn the filter counterclockwise to remove.
Replace the oil drain bolt when all the oil has been drained.
Place a small amount of fresh engine oil on the rubber seal of the new oil filter. Install the new oil filter. Tighten the oil filter hand-tight only.
Open the engine oil filler cap on the top of the engine and pour in four quarts of fresh oil. Check the oil level by pulling out the dipstick, wiping it off, reinserting it and pulling it out again. The oil level should be between the upper and lower marks on the tip of the dipstick. If it is not, you may need to add additional oil until it is between these marks. Tighten the oil filler cap when you are done.
Pull the oil catch pan out from under the Tucson and lower the vehicle to the ground.
