I have both and either is 100 times better than walking.

Great info, but could have also told pollution difference between those fuels used.

#2: Diesel motors produce high amount of some pollutants. On the other hand petrol engines produce high amount of completely different but still toxic pollutants ).

Great video manro. I've been a gearhead all my life, knew there were differences, but never really bothered to look into them much since they haven't been that popular in the US until recently. Actually amazed at how close they are. I thought there were bigger differences.

I had no idea about this, and he explained it so well, that even I understood it. Great video, manro!

3:55 "turbo feeds compressed air into the cylinder which helps the piston's descent therefore saving energy..."

That's a rather confused description of the function of a turbo. In fact by raising the air pressure at the intake, more air can enter the cylinder over and above what would be possible simply under normal atmospheric pressure, thereby allowing more fuel to be burnt, thereby producing more energy.

Diesel engines are more reliable, too, because there are fewer parts to go wrong. No ignition coil, contact breaker, distributor, wires, or spark plugs. And if you have a spill while refueling, it's far less dangerous. If you throw a lit match into a puddle of diesel, the match goes out.

#6 The video described with no confusion, you confused us all!
