For quality and long life use liquimoly 5w30, 5w40. It gives you safe mileage of 7-8k km mileage. Use vic Japanese oil filter costs 400.
And oil is 4300rs for 4 litres pack and u can get 1litre packsx3 for around 3100rs
For transmission fluid add liquimoly
Atf III it is for 1250rs per litre and you'll require 4L
Then if you still have budget to spend for quality. Add ceratec in engine oil or
Add atf additive from Liquimoly.
I've used kixx.
To use kix you've to change trans oil over 12-13k km because it looses viscosity.
Lm atf III gives you a safe oil viscosity over 25k. You can get it changed around 30k km
Remember liquimoly products seem expensive one time but they give more mileage, plus are not fake like other oils.
If you wanna do guzara.
Like my pakwheels fellow suggested you can use those oils for guzara.
But if you want Quality and performance.
Go with the products i wrote above.
