    I am new to the Chat but have put on a few miles on my 04 Prius (125,320). My Toyota Service log ends at 120k. What do you do for routine service after that? Just start over? I have searched through the boards but haven't found anything that addresses this question.

    Thanks!

    Yep, just continue the cycle at the suggested intervals.

    I hope that you have drained and refilled the ATF in your Tranny. If not, do it soon. Every 60,000 miles is a good idea even though Toyota doesn't suggest it in the service log.

    Good advice. In my opinion, by 120k miles you should have replaced the following fluids;

    1. Tranny fluid.
    2. Coolant.
    3. Brake Fluid.

    First, welcome Haiku and thanks for posting the big numbers! How are you doing in fuel economy? High 40s is par, and 50-something means you are good with the right foot.

    Agreeing with Jeff and Winston, pretty much. For the new model Prius the coolants end up getting changed every 50k, so why not do the WS transmission fluid at the same time?

    New iridium plugs every 100k, with removal and applying 'antisieze' to the threads at 50k suggested.

    Any good brake shop can easily test how much water is in your brake fluid. Above 1% suggests a change there. 2% will cause internal corrosion to expensive parts. Happens sooner in wet climates than dry ones; VA might be in the middle. Have it checked and then you'll know.

    By this time you must have your own philosophy for engine oil/oil filter/air filter. Stay with it, and maybe for fun, get the oil analyzed.

    Elder-Prius ought to pay more attention to 'the rubbers'. Coolant hoses and CV and steering boots. For the first, a coolant change is the ideal time to change hoses. You do have one drive belt (for the engine coolant pump) and please replace that before the cracks in it get too deep.

    Elder-Prius ought to pay more attention to mechanicals in the braking and suspension systems. Front wheel cylinders get corroded. Sooner or later somebody is going to need tie rod ends; I just know it. If your Prius is receiving competent maintenance (shop or DIY), all of the above is being monitored.

    Along those lines, when you bounce the front and rear bumpers and they keep bouncing, replace the struts or shocks.

    Lucky you, Haiku, you have one of the lowest-maintenance vehicles available. Just do what needs done and it will continue to provide good service.

    Thanks to you all for your guidance. I will compare your recommendations with my service log and will get on it. I have averaged low 50's mpg for highway driving ( I used to drive 150 miles a day) but lately with more city driving it has dropped to high 40's. Isn't this backwards?

    It's not quite backwards. The higher MPG at low speeds only happens when your Prius is fully warmed up. You are likely to be using it for a larger percentage of short trips now where the ICE has to run just to get warmed up. This lowers your MPG.
