How to check your engine oil

Thinking about your engine oil might not always be at the top of your to-do list, but it plays an important part in protecting your engine and helps keep your car performing at its best.

It only takes a couple of minutes to perform an engine oil check, and you’ll quickly see if yours needs a top-up.

  • When should you check the engine oil level?

    You should check engine oil regularly and in-between oil changes so you can keep an eye on it and avoid any long-term engine damage taking place. It’s particularly helpful to have a quick look at your oil levels before taking your vehicle out on a long journey.

  • What do you need to check your engine oil?

    You don’t need much to perform an engine oil check. Grab some paper towels or a clean cloth (that you don’t mind getting dirty) and a pair of gloves to help keep your hands clean. It’s good to have a funnel and a bottle of Mobil engine oil to hand in case you do need a top-up.

How to check your engine oil: step-by-step

1.Open bonnet  2.Remove dipstick  3.Wipe dipstick  4.Dip again  5.Take reading  6.Top up if needed  7.Replace dipstick, close bonnet
  1. Park your car on a flat surface and wait ten minutes to give the engine a chance to cool and for the oil to drain.

  2. Open the bonnet of your car and secure it well.

  3. Locate the dipstick and pull it out

  4. Use the cloth or paper towel to wipe off any oil from the dipstick.

  5. Push the dipstick back into place and then immediately pull it back out to see where the oil level is.

  6. There will be two marks on the dipstick, a higher and lower mark. The oil should be nearer to the higher mark, if it’s near the lower mark - or beneath the lower mark - it’s time to top-up your oil.

  7. If you do need to add more oil, make sure you have the correct Mobil engine oil at the right viscosity. You can then slowly funnel the oil in bit by bit, regularly checking the new level using the dipstick.

  8. Once finished, replace the dipstick, and close your bonnet.
