An internal combustion engine burns fuel inside.
Most bikes use a type of engine called a "internal combustion engine," which burns fuel to create power for the bike to move.
LPG or Liquid Petroleum Gas is a fuel, not a car. Pretty much ANY motor vehicle that is powered by an engine that burns fuel can be powered by LPG.
The fuel pump on a 1995 Jeep is in the fuel tank.
Oil is mixed with Petrol in what is known as a 2 cycle engine. This type of engine has no lubrication built in (as say an oil tank on a 4 cycle engine) so as the fuel/oil mixture burns lubrication is provided to the cylinder.
