Does my car accept conventional or synthetic oil?
However, for many consumers, deciding whether to pay more for synthetic oil during an oil change is a challenging decision. Synthetic oil producers claim their product will last longer and perform better than regular motor oil, but they charge more for each oil changesometimes twice as much. Is the more expensive motor oil worth it?
High-performance automobiles and those with turbocharged or supercharged engines are typically more likely to need synthetic oil. The oil selection is more difficult if the automaker of your vehicle does not mandate synthetic oil for your engine, and there is no simple solution.
Typically, synthetic motor oil outlasts conventional motor oil in terms of resistance to breakdown (typically 7,500 miles to 10,000 miles, sometimes up to 15,000 miles, as opposed to 3,000 miles to 7,500 miles for conventional oil). Increased viscosity that reduces efficiency, the depletion of additives, and the accumulation of sludge in the engine are all effects of breakdown. Even if you spend twice as much on synthetic motor oil, it won’t be worth it if you only need to replace your oil half as often. Synthetic oil for your automobile is also said to clean engines, improve flow in cold conditions, protect better in hot weather, and enhance turbocharged engine performance.
Synthetic mixtures are another option. These are mixtures of synthetic and conventional oils, as the name suggests. These hybrid engine oils are believed to last longer between oil changes than traditional oils but not nearly as long as synthetics. They cost more than conventional oils but less than fully synthetics. But once more, it’s difficult to pinpoint a specific number because manufacturers don’t always back up their assertions about how often to replace the oil. According to an independent testing lab we spoke with, synthetics frequently don’t perform all that much better than regular oils.
However, synthetic engine oil may be advantageous for older engines because it is less likely to produce sludge.
You should conduct a cost-benefit analysis if your car doesn’t require synthetic oil, but this can be challenging due to ambiguous engine protection and interval claims made by motor oil producers. Other than for your own peace of mind, there may be no good reason to spend more on synthetic oil. Using conventional in your car won’t be a mistake.
How long does it take to replace the oil in a Kia Optima?
For traditional oil, Kia advises having your 2021 Kia Optima’s oil and filter replaced every 3,000-5,000 miles. Generally speaking, synthetic oil needs to be changed every 7,500 to 10,000 miles. Remember that the best way to read the intervals that work best for your car is to consult your owner’s handbook and your franchise.
