Alto vxl will come with 75w gear oil, no need to change it till 60,000km.
No, alto vxl will come up with 10w40 delux engine oil, its ur choice to keep it runing on it till 5,000km or you decide to go for 0w20 and change before 5,000km. Its totally about your preferences. As I didn’t care about warranty, as they will always come up with some excuse to deny your warranty claim, so why go to suzuki till 60,000km, only for the sake of warranty
When i got my alto vxl, i changed first engine oil on 4000km from suzuki and then on 9,000km i switched to ZIC 0w20, as i have ZIC official dealership near my home.
