How Can You Check the Oil Level?

It is quite simple as well as similar to how you check your vehicle’s oil level. Take the dipstick from the lawnmower and with a clean rag, wipe it off. Now, insert the dipstick fully into the oil tank. To get the best results, ensure that the dipstick goes fully into its place, before you pull it out to check. Ideally, the residue mark should be between ‘full’ and ‘add’ notches. If the oil stain is lower than the ‘add’ mark, then it is time to add more oil.
