How to Read the Oil Dipstick in a Toyota Corollaby eHow Cars Editor
Checking your oil on a regular basis keeps your vehicle running smoothly and efficiently. There are some basic similarities in cars when it comes to checking oil, but slight variations in dipstick appearance can throw one off. The Toyota Corolla uses circles on its dipstick to help owners check their oil levels with ease.
Park your Toyota Corolla on a level surface then make sure your gearshift is firmly set on "P" for park so the car doesn't move while you are working. Open the hood.
Look toward the front of the car for a dipstick. A dipstick is a long metal measuring tool with a grip at the top end so you can pull it out of its sheath.
Grasp the ring at the top and gently pull the Toyota Corolla dipstick out of the sheath. Wipe it off with a rag or tissue to clean it.
Notice the two circles on the dipstick. These mark the safety zone for the safe running of your engine.
Slip the dipstick back into the sheath and pull it right out to get a clear reading. Look at the oil level on the dipstick without wiping it off.
Make sure the oil level mark is between the two circles on the dipstick. If it is over the top circle, you need to drain some oil out; if it is below the bottom circle, you need to add oil and recheck until the oil level lies between the two markings.
