Tools Needed:
The engine oil funnel is now ready to be installed where your oil cap screws on.
Check the dipstick after adding this amount of oil to see whether you are close to the recommended level. When in doubt, it is preferable to add oil gradually and check frequently as opposed to overfilling.
Remove the funnel once the dipstick’s reading is accurate. You can clean it by wiping it with a rag.
To build oil pressure and fill the oil filter, start your Prius and let it run for a little while. When the dipstick reaches the full mark, turn off your engine and fill off the oil.
