    Hey everyone, I just bought a 2014 Prius Four with 200k miles on it. I plan to keep this car for a long time. It currently is averaging about 37-39 mpg depending on my driving. I

    have a couple of questions to those with more experience than I do, I have a good budget to work with for preventative maintenance and would like to know what to have done. Ideally, I would really like to get about 10 years or more out of this car.

    I have already had the brake booster replaced as it was needed when I bought the car and the reason I bought is due to the great deal I got because of the brake booster/accumulator.

    I would like to try to get MPG back in the high 40s to low 50s if possible. What recommendations does everyone have for me? It has new brakes/rotors all the way around also. I have read some of the forums but in generally they are spaced out as issue to issue forms. I have some of the maintenance history but not all, it seems in general it was well maintained.

    Does this one have a new head gasket? How frequently oil was changed based on maintenance history (5K or 10K intervals)?

    It does not have a new head gasket, oil changes done approx every 5-7.5k miles

    You know its service history? Private sale or?

    keep an eye on the engine coolant level in the reservoir.

    For the most part yes, from what I can see on the carfax it has been well serviced.

    Make sure you are regularly checking the oil.

    Replace transmission fluid.

    Replace engine coolant and inverter coolant.

    Entire EGR system cleaning service including the intake manifold.

    Spark plugs? Take note that these are a VERY commonly counterfeit item, but the OEM's can easily go well over 200K.

    Mentally prepare for the head gasket to blow within the next 50k miles.

    Get yourself a OBD2 bluetooth dongle so you can monitor codes, temps, battery health, etc.

    With 200k miles, and so far no mention of EGR cleaning, there's a decent chance it's got a stop-leak product in the coolant, to hold the head gasket together.

    Again, private seller, dealership, or?

    ^ Always worthwhile, but considering you're at 200K, maybe just something to study up on, and concentrate on head gasket assesment:

    Private dealership, thanks for the recommendations so far. Is it worth it to just go ahead and have the head gasket replaced?
