So finally got time on saturday. Woke up called the dealership took an appointment for the 5k service.
I politely asked the service advisor, oil konsa daleinge, he said sir ultimate. 10-40 I said 0-20 daldein. He says sir company ne mana kia hua hai. I said okay. Carry on (wagonrs manual says 0-20, while no where Altos manual states 0-20) maybe the engines tweaked.
I dont mind the engine oil. It's okay. But what's astonishing is, since someone mentioned Altos oil filter is made in japan and it's very expensive. When I got the bill for rs.2650 I thot they didnt add the oil filter on checking its rs.203 LOL.
I asked the advisor he says sir jhoot nae bolra since suzuki is closed we are out of stock. This filter is totally okay. It won't harm your cars warranty.
Now I'm thinking to find the original oil filter from market and switch to after marker 0W20 caltex aswell. I agree the oil and filter used by the dealer ship won't harm my warranty but why risk my car.
