Around 3 litres I think? Should know I changed mine yesterday just can't remember what was left I used 5w 40 synthetic for the first time yesterday I usually use 10w 40 but changed now as many on here seem to use 5w 40
According to my manual for the glanza V you need 2.6 litres without a filter change and 2.8 litres with a filter change,
Thats the ammount i use and it brings the oil level all the way to the full marker on the dipstick,
Personally i would used 10w30 in the winter as it is a lttle thinner than 10w40 which will help the car warm up quicker
i wouldnt be going by manuals or litres to be honest..
drain out old oil, change filter.. top up with new oil to max level on dipstick and turn the engine over for a for a minute or so..turn off, let the oil settle and check the dipstick again and top up..
NOTE; people tend to forget when changing oil/filter that you need to prime the engine, filter and turbo before you can assume that the oil level is right...
