Hi, last Saturday i have serviced my Swift VDI in delhi from Service Masters, Okhla at 20K oddo reading but i feel that service centre have actually not replaced the engine oil which they have charged from me. I have shown the engine oil to representative when i got the car back after service which was looking as Black, he told me if you start the car just after changing the engine oil, it is hard
Why MultiJet Engines can't deliver power upto 100 bhps?
And why they produce more torque like 209Nm more than city's engine?
And if i add a tuning box or go for a remap does it gains me 100+ bhps? And how much does it alter my cars engine? ;lanning for my Sail diesel.
