Step-by-Step Guide: Checking Engine Oil Level

  1. Park the vehicle on level ground and ensure the engine is turned off.
  2. Open the hood and locate the dipstick, which is typically a brightly colored handle labeled “Engine Oil.”
  3. Pull the dipstick out of the dipstick tube.
  4. Wipe the dipstick clean with a cloth or paper towel.
  5. Reinsert the dipstick fully back into the dipstick tube.
  6. Pull the dipstick out again and observe the oil level.
    • If the oil level is between the minimum and maximum marks on the dipstick, it is within the acceptable range.
    • If the oil level is below the minimum mark, it indicates that the engine is low on oil and requires topping up.
    • If the oil level is above the maximum mark, it indicates that there is an overfill and some oil needs to be drained.
  7. If the oil level is too low, add the recommended oil through the oil filler cap, a little at a time, and recheck the level using the dipstick.
  8. If the oil level is too high, drain the excess oil using the drain plug and recheck the level.
