I have a 2004 4cyl Ranger. When I got the truck I couldn't get a reading on the dip stick so I drained the oil and put in new oil and a new filter. I put in exactly the amount of oil the book called for so I know it's full. Thing is that it still doesn't read right. I am starting to think the last owner may have lost the dip stick and just stuck another one in.
If anyone has a picture of the right dip stick I would love to see the correct one. I'd also like it if someone could measure the length of theirs so I can measure mine to see if it's correct.
