Hyundai is one of the most popular vehicles in the US. Every year, the company breaks sales records, and in 2025 it almost crossed the 1 million sales threshold. But as much as people love the car, it’s become increasingly clear that many don’t understand proper car maintenance. Luckily, a mechanic on TikTok explained exactly how poor oil care, in particular, is making the car a nightmare for drivers.
The mechanic goes by Sparks Car Care (@sparkscarcare) on TikTok, and many commenters in his comment section were commending him for “restoring faith” in his trade, especially amid recent reports about mechanics either leaving the profession or, in some cases, being fraudulent. But really, what the mechanic was saying should be common knowledge — even for non-Hyundai drivers.
