Tyre pressure also plays a good role in affecting FE. I usually go 2 psi higher for city and 3 psi higher for highway driving. It gets me better figures.
Wouldn't the +3psi hamper the braking ability of the car ? I stay close to the highway. Would love to give this a shot

I use 33psi on my Fiesta and 32psi on my alto/zen, especially for highway driving. I haven't noticed any difference in my braking, though it may well be there. I find the ride to be pretty good, but I suppose it helps that I am driving on decent roads. Be a bit careful of higher pressure on bad roads. It would make for a harsher ride.

My suggestion would be to try it and see what happens. Worst case, carry a gauge with you and tyre pressure can be reduced on the highway itself. Just make sure all tyres are the same pressure when you do that though
