I have never owned any vechile until I bought the Lasaber for the wife that had a low oil level sensor. I know that known of the Toyota's that any of my family has ever owned has ever owned one. I think they are silly. If someone is too stupid or lazy to check their oil when they get gas then they should not own a vechile!If the vechile burns so much oil that the OEM thinks it needs one or the OCI is so extended that it needs one then something is wrong! I would rather have oil pressure guage, amp meter and temp of all fluids.
