Check the level before you drive
- Park on level ground. Turn off the engine and follow the waiting period in your owner's manual.
- Pull, wipe, and reinsert the dipstick. Use a clean cloth, then push the dipstick all the way back in.
- Read the level between the marks. Pull it out again. The oil should sit between the upper and lower marks.
- Top up a little at a time, then recheck. Use the specified oil. Don't fill above the upper mark.
A quick level check, not a full oil-change guide. Follow your manual's procedure.
Confirm with your own manual, dipstick or door-jamb label.
