Toyota Vitz/Belta owner's manual recommends any engine oil with grade: 5W-30 ideally its good to change all the fluids including:
engine oil+ oil filter,
(Get the odometer reading noted after all the above so as to be used for reference for the next drain interval)
Get the condition of brakes checked,
Get alignment done.
also change air-filter.
Doing all the above at one time might seem a cumulative expenditure, however, if done now, it will save you hassle for a long period of time. Always stick to OEM parts/ manufacturer's recommended grades & specifications.
