Bro, first of all get original parts which are directly involved in combustion of the vehicle. Which includes:
1. Genuine toyota oil
2. Genuine toyota oil filter
3. Genuine air filter
Then check proper tyres inflation and alignment. It plays very important role. Check these parameters then start driving like old men do. That is accelerate very patiently and gradually avoiding any abrupt acceleration & braking.
Hope this may solve your problem
