It's very important to check your car owner's manual, as it contains the specific oil grade, viscosity, and specifications that your manufacturer recommends for the country and climate your car was made to drive in. This is the only reliable source to determine the exact spec and grade that your vehicle needs. These details aren’t random - they’re based on how your engine was designed, the performance it requires, and the climate conditions your car was built to handle, so getting the oil spec right is important.
Using the wrong oil can affect fuel efficiency, increase engine wear, and even shorten your engine’s lifespan. That’s why the car owners manual should always be your first reference poin and not guesswork, advice from friends, or online lookup charts.
