Good product
I got it for 1800₹ for my harrier , which translates for 100₹ a litre , which is extremely value for money ( tata retails at 180 per litre ) Nice packaging , no leaks , atleast for harrier you will require a funnel to fill . No pickup loss no nothing as mentioned by few ( all DEF are same ) , as good as tata original DEF .
