@ 41500 km a new sound has started in my Indigo.
When you start the motor , sometimes , there is this pronounced
rough idle sound ( frfrfrrffrfrrfrfrfrfrfrf ) accompanied by incresed vibrations.
goes away when throttle is pressed or if clutch is depressed.
Doesnt occur everytime and all is well after either of the above.
Need help in diagnosing this problem.

I need to know the exact quantity of Engine oil for the Tata Indigo’s 475 IDI TC engine .
The service manual recommends 5.5 lit though the 475 IDI NA diesel used to take 4.5 lit. only if i am not mistaken.
On filling 5 litres only with filter change the dipstick max. mark is breached by 2/3 mm. Somebody suggested that maybe half lit.of old oil remains in the sump, which personally i am not sure of.
I suspect it takes only 5 lit. but since most Tata’s motors consume some amount of engine oil through the drain interval of 7500 km / 6 months , it may take say about 250 ml more ( over 5 lit.) as top up.
But 5.5 lit. at the time of oil change seem unlikely.
Is it one of the Tata typos?
I read that earlier Vista manuals too specified 3.7 lit of oil as against about 3.2 taken by the same engine in swift / fiat.

The point is you’ll realize that you are probly being charged for half a litre more only if you get the oil changed outside the TASS.
Can anyone shed light on this ?
