Image Credit: calypso.solara / TikTok.Some people skip flossing. Some people skip the gym after January 15th. And apparently, some people skip oil changes entirely, then go on TikTok to brag about it. According to her TikTok, content creator Annabelle, who goes by @calypso.solara, told millions of viewers that she has never once had her oil changed in the four years she's owned her car. Her logic? Just keep pouring more oil in when it gets low, and skip the whole "changing it" part altogether.The video racked up more than 6.4 million views, and Annabelle stood firmly behind her method. She explained she has driven her car across several states without a single hiccup, and she is tired of people warning her that her engine is a ticking time bomb. "Y'all keep telling me my engine finna blow. When?" she asked her audience, sounding less like someone in denial and more like someone daring fate to prove her wrong.That is when Valvoline, a company that knows a thing or two about oil, decided to step into the comments. Their response was short, blunt, and got more than 112,000 likes: "U can't be serious." Even the professionals could not let this one slide quietly.AdvertisementAdvertisementCommenters piled on too, and honestly, some of them were pretty funny about it. One person joked that her oil filter was "fighting for its life." Another said her engine probably resembles the inside of an air fryer at this point. We are not doctors, but we are fairly confident that is not a compliment.Topping Off Is Not The Same As An Oil ChangeHere is the thing. Adding oil when the level gets low, often called topping off, is not the same as an actual oil change. A real oil change drains the old, dirty oil completely, swaps out the filter, and starts fresh. Topping off just adds new oil to old oil that is already full of grime, metal particles, and leftover combustion residue. The filter, which is supposed to catch all that junk, never gets replaced either, so it just keeps recycling debris through the engine.There is also a chemistry problem. Oil contains additives designed to fight wear, corrosion, and oxidation, and those additives break down over time. You cannot restore them by simply pouring more oil on top, the same way adding fresh coffee to an old, cold cup does not make it a new cup of coffee.So How Often Do You Actually Need OneThe old "every 3,000 miles" rule is outdated for most modern vehicles, with many automakers now recommending intervals of 7,500 to 10,000 miles. The real answer lives in your owner's manual, so that dusty booklet in your glovebox is worth a look. Oil also degrades with time, not just mileage, so even a car that mostly sits in the driveway needs its oil checked regularly.AdvertisementAdvertisementOur take: Annabelle's car may be running fine today, but "it hasn't broken yet" is not exactly a maintenance philosophy we would recommend. A few minutes and a modest bill every several thousand miles beats a very expensive engine replacement later.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
