5W-20 and 5W30 motor oil are winter viscosity grade oils primarily recommended for older engines and light-duty use. These oils are best utilized in colder temperatures.Is synthetic oil OK for older cars?
It protects better, performs better, and lasts longer, and it's no longer made with a chemical compound that could hurt older vehicles. Modern synthetic oil is safe to use in all types of vehicles, ranging from new purchases to classics to aging not-so-classics.Is Thicker oil better for older engines?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil - 10W - can help protect worn engine bearings as well.Is Synthetic Motor Oil Bad For Old Cars?
What happens when you use 10w40 instead of 5w30?
Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40.

While both 5W20 and 5W30 motor oils are suitable for high mileage engines, the best viscosity type for your vehicle depends on how the manufacturer designed the engine. Using 5W30 when it is advised that you use 5W20 can result in your vehicle not getting good fuel economy.Is 5W30 good for high mileage?
Full synthetic 5w30 oils are recommended for high-performing cars, those that carry heavy loads, and vehicles operating in high temperatures. These oils are made with high-performance additives to enable them to deal with extreme conditions.Which is better 5W30 or 5w40?
5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.Should I use 10w40?
So, if you drive in a warm climate — especially more than 32°C (90°F) — or have an engine that runs hotter than others, 10W-40 oil viscosity is a good option. This higher viscosity oil is designed for hotter temperatures and can handle the added heat stress from the environment.When should I use 20W 50 oil?
A SAE 20W-50 motor oil is typically used in older vehicles or in particularly warm climates. Castrol GTX 20W-50 has been specially formulated to help extend the life of your engine by keeping it free from sludge, even when operating in extremely high temperatures.Which is thicker 5w30 or 10w30?
So both the oils 5W–30 and 10W–30 have exactly the same viscosity (SAE 30) when your engine is running, and will perform in the same way. However, the 10W–30 oil will be thicker (higher viscosity) than the 5W–30 when it is cool.Can you switch back to regular oil after using synthetic?
Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time.
