    Hello everyone I have a 2008 Toyota Prius with 300,000 miles on it I have a main rear seal leak and go through two and a half quarts of oil every oil change I'm wondering if I can add Lucas Oil Stop to my oil change to see if I can slow down the main seal leak?

    I wouldn't use any "stop leak" products, in any fluid system.

    they tend to stop flow in places you don't want to stop flow like:
    cylinder passages
    heat exchangers
    small orifices
    pumps
    accumulators
    etc
    it's always better to fix the leak properly whether it's a seal or what have you

    Your thinking coolant stop leak he’s on the oil side.

    The effect can be the same, that stop leak stuff can easily block small passages.

    Oh yes it’s at best a temp fix at best with bad after effects.
