Locate the Dipstick: The oil dipstick is usually situated on the side of the engine. It is a long, thin metal rod with a T-shaped or L-shaped handle that allows you to grip and pull it out.
Wipe the Dipstick: Using a clean cloth or paper towel, wipe the dipstick clean to remove any oil residue. This ensures an accurate reading.
Insert the Dipstick: Carefully reinsert the dipstick into the oil filler neck (where you pour the oil). Push it in until it’s fully seated.
Retrieve the Dipstick: Remove it to check the oil level after reinserting it. Hold it horizontally to get an accurate reading.
Observe the Oil Level: You’ll notice two marks or indicators on the dipstick. One is typically labeled “Full,” and the other is labeled “Add” or “Low.” The oil level should fall between these two marks. If the oil level is near or at the “Full” mark, it’s adequate. You need to add more oil if it’s closer to the “Add” or “Low” mark.
Add Oil (If Necessary): If the oil level is low, carefully pour the appropriate type and amount of oil into the oil filler neck. Be cautious not to overfill, as excess oil can lead to engine problems.
Recheck the Level: After adding oil, repeat the process. Reinsert the dipstick, then remove it to check the oil level again. Ensure it now falls within the “Full” and “Add” marks.
Secure the Dipstick: Once satisfied with the oil level, securely reinsert the dipstick into the oil filler neck and ensure it’s fully seated.
Clean Up: Wipe any spilled oil and residue from the engine and dipstick, and securely close the oil filler cap.
