When should you use high mileage oil?
Who needs high mileage oil? Cars with more than 75,000 on their odometer can usually benefit from high mileage oil. Older vehicles with fewer miles can benefit too, as engine seals can erode over time regardless of mileage. Degraded seals mean leaking oil, and leaking oil means your engine isn’t working at its best.
Can you put high mileage oil in a new car?
Using a high-mileage oil in a new vehicle would be ill-advised, since no manufacturer recommends this type of oil for a new vehicle. Would it harm your engine? Most likely not, but it would be better to adhere to what is specified in the owner’s manual, at least until the warranty has expired.
Can high mileage oil damage an engine?
High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. Most vehicle manufacturers would say it’s normal for an engine to consume some oil between oil changes.
Can I replace 5w30 with 10W40?
Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
What if I put 10w40 instead of 5w30?
One must use the oil specified by the manufacturer. If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
What is the best grade of engine oil?
In tropical weather, most OEMs still recommend multi-grade products, such as SAE 15W-40, because the lubricant flows faster through the engine than a pure SAE 40 even at higher ambient temperatures. Another important consideration when choosing an engine oil is the quality certification or performance level.
