What Is The Toyota Scion Tcs Oil Type?

Answering the question of which type of oil is ideal for your Toyota Scion TC can be somewhat difficult. The 2007 model year of your car requires either 5W-20 or 0W-20 full synthetic oil. However, the mechanic replaced it with semi-synthetic API SM 5W-30 oil, which is not recommended by Toyota for your model.

Should the oil be changed again to the recommended 5W-20 or 0W-20 oil, or may the semi-synthetic API SM 5W-30 oil be used? It depends on how important it is to you that you use the proper oil for your car.

5W-20 or 0W-20 engine oil is the ideal choice if you want to retain the maximum level of performance and protection for your engine. The complete synthetic oil will keep your engine clean and running smoothly, and it will also be more resistant to heat and engine wear.

Alternatively, if you’re seeking for a more cost-effective alternative, you might continue to use semi-synthetic API SM 5W-30 engine oil. Even while it may not provide the same level of protection and performance as full-synthetic oil, it should be suitable for your engine.

In the end, it boils down to your own requirements and tastes. Follow the manufacturer-recommended oil change intervals for your vehicle to guarantee optimal engine efficiency and protection, regardless of the oil you use.
