DIESEL is more economical than normal petrol/gas
CNG (compressed natural gas) is better because it's a cheaper kind of gas, and you get more MPG (miles per gallon) out of it.
About 18 miles!
18-29 miles per gallon
More expensive gas burns slower and allows the car to run more efficiently, so you would get more miles with more expensive gas. So a minivan with higher grade gas would get more miles.
More than likely around 25 miles.
The gas in a V8 car will last varying amounts of time. One tank will last about a week if you are only driving 30 miles each day.
last month when he used 21 gallons of gas
14-18 miles per gallon not 50
More. If the car got a really poor 10 miles per gallon, it still would travel 150 miles before running out of gas.
That depends on the size of the gas tank. At a constant rate of speed, a 20 gallon tank will last for 560 miles.
It depends what kind of BMW you get, if it's a bigger one like the X360 then it takes up more gas than the smaller ones, but all BMWs gas is expensive because they use premium
Diesel engines are generally more efficient than gas engines. A Diesel Pickup truck will normally get far more miles per gallon than a gas one and still have equal or greater power available. Plus diesel engines tend to last much longer than gas engines easily running well over 300k miles with little to no issue.
