For me, I stick with diesel for most cars.
Pune petrol pices - Rs.72.xx,
Diesel price - Rs.52.xx.
Price diff is some Rs.20/L.
Even if complete so called subsidy on diesel is removed, the price hike will be of max to max Rs.7.5-8/L as this is current under-recovery for oil cos.
This means you will still save 20-8 = 12/L even after diesel prices are completely deregulated. Apart from this price diff, there is higher FE of atleast 30% in case of diesels over petrol, which makes running costs far less. And with new gen diesels, maintenance price diff too isn't big as it was the case earlier.
By the way, does anyone have an idea what gives more margin to a car maker- a diesel or a petrol car?
In most cases, the manufacturing costs are almost the same. Car cos hike diesel car rates because demand is more. In case of Merc, the price diff is not even 2-4% !!
Let diesel price increase & see price diff in petrol & diesel cars reducing.
