When the vehicle weighs more, the engine has to exert more effort to move the vehicle than it would moving a smaller vehicle the same distance. The extra effort comes from the incresed fuel consumption.

The approximate fuel consumption of this engine according to my experience is 10 Km/ Liter. It gives you more extra km. if you use tubeless tires size 205/70 R15" C tires.

Up to one pound a month, which adds up to 12 pounds per year!

Cured meat typically is fully cooked. However, it is best to check the packaging on the meat to be sure that it does not require extra cooking before consumption.

no because it is to small to make a difference

Any extra drag on the car would increase fuel consumption.
