I dont think you do really need to worry about the brown smoke.
*Have you changed your fuel filter?
*Whats the cost to clean the throttle body?
I don't know the cost of general checkup at Maruti. Mostly it should be less than Rs.500 or even free.
You can do the compression test from any of the big maruti service center.
video was really very nice.
mechanic took 350 rs for throttle body.
he also tested fuel pressure by hand and told me that, fuel is flowing properly and filter does not require replacement.
since the colour of oil has changed,now i am also of opinion that something is very wrong with the engine.
i am constantly monitoring oil consumption and will reply soon about quantity consumed in 500 kms.
if i go for piston rings replacement as prescribed by mechanic, how much will it cost?
is rings replacement and overhaul worth it? how long will my car last after that?
i initially planned to keep it for further 3 years and then sell it, as i live in delhi and cars older than 15 years loose their resale value completely because vehicles older than 15 years are now banned.
but considering current situation, i am thinking of selling it within one year. but i am worried, because no one knows the exact issues and i might loose a good car.
one more thing, could too thin engine oil be the culprit?
my mechanic poured 3.5 ltrs 5w30 oil and it is above 40 deg cel in delhi.
should i give a try to 5w40 or so? could it be the culprit?
as per above chart i should use 10w40/10w50?
