after hunting a lot in the internet regarding Oil specs for Vento Diesel Highline, finally the looked into the manual.
I was shocked the manual had nothing written about the oil spec! It just said (a)
& below it was put like this
(a) - this information was not available at the time of publishing this book!
Called up VW Downtown & they too dint reveal much about its spec. Finally went to their showroom and purchase 1ltr oil. Topped it up myself, near off. Oil Spec Used:
Castrol SAE 5W40
Cost: Rs.970/- (including tax etc)
Pictures for your reference, sorry for poor quality.
I also added water to the coolant tank & its working fine.
This last picture was at a parking lot very close to the VW showroom. I was just wondering in case somebody stole something out of this Vento (Parked carelessly like this, who will the customer talk to?
