    New cars absolutely do have dipsticks; they’re the ones designing them.

    Notwithstanding the potential for software bugs or other issues inherent with monitoring oil levels only digitally, monitoring just the oil level is not the sole purpose of the dipstick. Being able to physically see a sample of the engine oil is a vital diagnostic tool and can alert an owner or mechanic to a head gasket problem or other oil contamination issue, or if something is grinding metal shavings into the oil, etc.

    For what it’s worth I have yet to actually physically see a new vehicle without an oil dipstick. I guess they’re out there, but so far I’ve been lucky. But I have already had quite a few automatic transmission equipped cars without a transmission dipstick cross my path, and that’s already enough of a pain in the ass. If you’re lucky there’s a side plug in the transmission case you can use to check the fluid condition and level (after crawling under the vehicle…) but in a lot of cases there isn’t even that – your only recourse is to drop the transmission pan off entirely, which causes you to lose all the fluid in the process. And you’ll probably also have to replace the gasket while you’re at it. Needless to say, this is an incredibly moronic design decision.

      My wife has a 2015 Jeep Grand Cherokee. The AC condenser got a leak in it and it was going to be over $2k to fix in a shop. I took it on myself to save money. The condenser mounts to the back of the radiator, so I had to get at it by removing the bumper and everything between that and the engine block. Also attached part of the radiator is the transmission cooler. Unhooking everything meant that I was going to lose some fluids, but that was fine, I’d top them off and pay to have refrigerant added.

      After I reassembled, I when to check the trans fluid levels, and couldn’t find the dipstick. It turns out, like you said, if you crawl under the vehicle, on the back of the trans pan is a bolt you can remove, and if you have a special dipstick that you buy separately for this sole purpose, you can stick it in there to check levels. There’s not way to add fluid without pumping it in there, but at least you can see how much you have.

      Since I only lost less than a quart, I took it into the shop, explained what’s up, and asked for it to be topped off. The shop guy calls back later, and told me that to do the trans fluid, the filter is only sold with a whole new pan, and because Chrysler, the fluid cost like $40 a qt, and I needed like 15 to fill it. It still cost more than $800 to just do that, then more than $500 for the refrigerant. I still saved about $500-1k in parts and labor for what I did, but, the lack of dipstick and fill tube was an extremely inconvenient and expensive thing.

        You don’t need a disptick, you just fill it until it starts coming out of the hole. Lots of heavy equipment works this way.

          You just check it with your finger. Then you use a container with a tube and squeeze the fluid in until it overflows.

      For what it’s worth I have yet to actually physically see a new vehicle without an oil dipstick.

      It seems to be mostly a euro thing. BMW stopped using oil dipsticks nearly 2 decades ago. Land Rover also somewhere in the late 00’s.

      But I agree it’s a moronic idea. Not only does it prevent you from checking oil condition like you said; if it’s after an oil change, it takes about 15min just to check the level (and another 15 if you messed it up). At $150+/hr shop rates, that adds up.

        I used to be a lube tech in a different life 15 years ago and would occasionally see vehicles without dipsticks. Like you said the German brands like BMW and Mercedes but also Chrysler vehicles like the 300 and Magnum had a tube for the transmission dipstick but no dipstick inside of it just a cap on the tube.

        It seems to be mostly a euro thing. BMW stopped using oil dipsticks nearly 2 decades ago.

        I was about to make this joke: “That’s just not true. My 2008 BMW had a… holy shit, that car is nearly 2 decades old now.” Then I went to confirm, and that car did NOT have a dipstick. The car came with 5 years of “free” service and never gave me a day of trouble, so I never realized it didn’t have a dipstick. That’s probably a major reason it was removed, since even a DIYer like me who likes to work on things myself never even tried to use the dipstick in 4 years.

      I thought it was hilarious when I saw that Briggs and Stratton has been selling small engines featuring “no oil changes needed” (or possible). They advertise that it’s “oiled for the life of the engine” … well, by definition, yes, that’s like saying “if you light a man on fire he’ll be warm for the rest of his life”. These companies are so predatory and transparently trying to turn durable products into disposable replacement services, it’s unbelievable.

        Can confirm; I used to manage a hardware store with an attached small engine repair shop. There’s a reason Briggs and Stratton abbreviates so readily to “BS.”

        They’ve been trying to do the absolute bare minimum possible to maximize profits and making their machines flimsy and deliberately uneconomical to repair for several decades, now. All I can say is that we ought to be thankful for aftermarket parts.

    I’ve had a car with where the oil pressure sensor failed; combine that with an oil leak, and you quickly have a major problem. So, what happens when the sensor telling you the oil level fails? A dipstick is extremely unlikely to ever fail to work correctly, so…?

      I know it can last longer than that, but I think there is a benefit to doing so even if it doesn’t need changed that often. It’s the same reason I have my mechanic do my oil changes instead of doing them myself. It’s so that they can look at the rest of the car and let me know about problems before they become a much more expensive fix. Kinda like going to a doctor for a yearly checkup and blood work.

      I can fix almost anything on a car if I know what the issue is and have the shop manual, but I don’t work on cars enough to know all warning signs or quickly diagnose things.

      However, I do realize how difficult it can be to find a mechanic that is trustworthy, competent, and reasonably priced. I’m generally not a fan of dealership mechanics or the places that are dedicated to cheap oil changes. Not saying none of them have good mechanics, but it can be hit or miss.

      That chronological duration is more of an estimate based on how much the “average” car may be driven and is just to give someone an idea of the frequency.

      The standard for cars built for synthetic (“conventional” cars may have a bit more susceptibility to contamination, so they normally have shorter durations) usually usually go for 10-15k miles (~16-24k km). So going 30-45k miles in a year isn’t really unheard of. (Some cars are much less, while others like company cars/taxis can be more than double)

      Depends on how much you drive, and what the recommended interval is. If the interval is 7k miles, and you drive 18k in a year, yeah, you need to change the oil 3x/year.

      It seems to me that counting the number of cycles each makes, and basing your intervals off that would make more sense than mileage. If I’m constantly running at high RPM, that should require more frequent oil changes in terms of mileage.

    This sounds like an old Mercedes problem: Why even having a dipstick when there isn’t any drain bolt? The Mechanic sucks all the oil from the top using a vacuum. Grime buildup down in the oil pan? Ain’t care! The car will break anyway, once it’s out of warranty.

      I would argue that it adds a new failure point, and a catastrophic one at that.

      Yes, many hunans don’t monitor their oil properly. I’ve seen some destroy engines because they thought the low oil light could be ignored for a week.

      Even if you still had the dipstick, owners would become reliant on the sensor and grenade the engine when it gets it wrong. Remember how Teslas had hoods that flew open while driving? The problem wasn’t the latch. The problem was owners relying on a crappy sensor.

    Knowing the exact oil level is very important for new cars. The piston rings are now made of softer metal to get a few more mpgs. If you overfill oil, you will get blow by, damage the rings, and start burning oil. Toyota now has an involved process of changing oil, running the engine, then topping off the oil while the engine is hot so as to not overfill. But not even my dealer follows that official procedure Toyota put in their manual.

    I don’t like it because:
