Low mileage drivers: keep sticking with months vs miles/km for maintenance schedule?

    I just received a notice that my car is due for maintenance. In the past six months, I've put on 3000 miles (5000 km). I average ~6000 miles (10 000 km) per year, and have been following the time-based maintenance schedule since I bought it new. I'm just wondering if this is still the smart thing to do, or am I just throwing $ away.

    It's actually my first new car, so I'd like to ensure that it lasts as long as possible. So, I may have answered my own question. ;) Just curious as to what others think, and have done. I'm fine with doing my own oil and filter changes, so that's not an issue (except for trying to shimmy my fat @$$ underneath the Prius... :ROFLMAO:).

    I have gone to annual oil changes on my two low-usage Toyota hybrids. Each gets fewer than 6,000 miles a year.

    agreed, once a year oil change. it depends on the service. for now, i would go by miles

    when it is much older, time becomes more important on certain services. not engine oil though.

    The "maintenance due" message simply means you've traveled 5,000 miles since you last reset it. It's really up to you to keep a maintenance log to determine what or when anything is due. Personally, I give more credit to miles driven (10,000 for oil) than time (12 months) in deciding when I need to change the oil. This is based on sending used oil samples to Blackstone Labs and having them tell me that there is plenty of additive protection left in my oil. If it takes me 18 months to reach 10,000 miles, then so be it. This also assumes you do not perform "frequent short trips" where the oil does not reach normal operating temperature...otherwise known as "special operating conditions"

    Oops, I should have been clearer on the 'notification' description. I meant a snail mail notice from the dealer. I've never received the 'maintenance due' from the car.

    I agree with using Blackstone. I've used them with four previous cars. The only problem with the current Prius is that all of the oil changes have been completed by the dealer. I thought of handing them one of the Blackstone jars and asking them to grab a sample when it's draining, but I wouldn't fully trust the results unless I did the change myself.

    Speaking of Blackstone, when you send yours in, do you include the percentage of actual ICE usage in their 'mileage' box? Or, just the odometer mileage?

    I follow date schedule dutifully, miles always lags behind. For example the coolant change at 10 year mark, even though we only have 89000~ kms (schedule says 10 yrs or 160K kms). Ditto for oil changes:,every 6 months (3rd gen CDN schedule).

    But I’m DIY’ing, so doesn’t cost much. And I need something to do, lol.

    My car has traveled very few miles this year. Only a couple hundred miles per month and the ICE has only run a few times when I wanted to burn off some old gas. I'd guess the ICE has only run for an hour this year. I have synthetic in it, so I'm waiting till my next 1000 mile trip to have the oil freshened. Maybe next summer.

    Just the odometer reading.

    There’s quite a bit of variables. One big variable is oil filter. I have seen the YouTube videos of people opening up FRAM oil filters and I would definitely be scared to use the cheapest grade one. I’m pretty sure it’ll provide you filtering up to a certain point, but I would never go 10,000 miles with it. I believe the OEM is a mid level quality filter, which I wouldn’t want to go too close to the 10,000 miles. I rather be safe going near 10k miles or 1 year if I was using premium oil and filter.

    If it wasn't for warranty requirements of 10k miles or annually, I would go on mileage, with an annual visual check, as I do less than 3k miles a year.
    As it is I have an annual dealer service and I can't even tell if they've changed the oil as it still looks new before I take it in.
    It seems a waste of good oil as this modern synthetic stuff is good for 10-20k miles, especially as the ICE only does about half the mileage of the car.

    Honda has a much more advanced in-dash maintenance reminder. It apparent monitors various factors: miles for sure, but others as well. Not sure what, but I’d suspect factors that would vary the need for maintenance, say short trips where coolant gets only partially warmed, average revs, and so on. It does vary the miles to maintenance, not just counting distance travelled.

    Also, it’s more than just a simple alert; it counts down percent to next maintenance, and once it’s below 15% remaining a code is displayed, which you can look up in owners manual, decipher exactly what needs doing.

    The latter is priceless with shady dealerships pushing the extras.
