Can I use 10W40 synthetic oil?
Can I use 10W40 synthetic oil?
Using the correct viscosity oil eases starting, reduces friction, and slows wear. For even more effective start-up protection, use a synthetic 10W-40 instead of a conventional 20W-50. The synthetic 10W-40 flows easily and still maintains enough viscosity to protect piston skirts and bearings when it gets hot.
How long is Castrol synthetic oil good for?
Most synthetic oils, such as Castrol, are rated to last between 10,000 and 15,000 miles or six months. These ratings are only recommendations typically applied to “normal driving,” and do not reflect severe driving conditions that may require more-frequent oil changes.
Is 10w40 OK for 5w30?
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.
Are there additives in Castrol Edge synthetic oil?
Conventional oils may contain additives including zinc or ZDDP that help reduce cylinder wash problems common with conventional oils. Synthetic oil like Castrol EDGE is created through a man-made process. It often starts as an extract or byproduct of crude oil, but then goes through much more refinement.

What kind of oil is Castrol GTX made of?
Regular or conventional oil such as Castrol GTX is made from crude oil and refined through a process that thins the viscosity of the oil to desired levels. Conventional oils may contain additives including zinc or ZDDP that help reduce cylinder wash problems common with conventional oils.
What’s the difference between 0w40 and 5w40 motor oil?
The second number represents the oil’s viscosity at the engine’s normal operating temperature (usually 212 Fahrenheit). Oils that are too thin at operating temperature don’t provide adequate protection while oils that are too thick reduce efficiency. 0W40 vs 5W40: Which is Better?
