Well from my experience :
1.Change the plugs to iridiums you mileage and power will improve(You can use Denso IK20,NGK BKR6EIX-11, NGK IFR6J11, AutoliteXP3923)
2.Use fully synthetic oil like ZIC XQ.
3.Keep your air filter clean.
4.In initial 1000 Kms don't drive above 100 Km/hr and don't accelerate much.
5.I also recommend not to use the tank to last drop, don't take it beyond 1/4 of tank.
- When in the workshop stand by the car, and don't let the worker do anything extra/suspicious.Get the entry done for every service in warranty book by the authorized service centre.
7.Drive in the RPM range 1500-2500.
- Get your car washed with good car wash and then get it waxed with good wax.
9.Keep the air pressure as per recommendation(33 front,30 rear) if the roads are good in the areas you drive.
