do 4 cliynders get the best for miles per gallon?

Question

do 4 cylinders get the best gas mileage?

Answer 1

Not necessarily.

You want more of an answer? Fine.

First off, there are 3 cylinder cars.

Fuel efficiency isn't as simple as the number of cylinders, or even MPG. A larger cylinder will tend to use more fuel. There have been six cylinder engines that use less fuel than some four cylinder engines. An older car will use more fuel than it used to. A car that hasn't been properly maintained will get worse fuel mileage. You'll also use more fuel the more work you make your car do. You could put a scooter engine into an SUV, but you won't get good gas mileage. You'd probably be able to walk faster, too.

You should figure out what you need your vehicle to do, then look at the estimated fuel mileage. Once you own your vehicle, start doing things to maximize your fuel consumption: drive conservatively, use high quality fuel (high octane does not equal high quality), switch to synthetic fluids (oil, transmission, etc), make sure your filters are clean, properly inflate your tires, and carry as little weight in your vehicle as possible.

Answer 2

Something like a diesel train or jet plane may measure its fuel efficiency by how many gallons of fuel are burned to travel one mile. That would be gallons per mile. Most vehicles will go several miles on a single gallon, from about 5 miles for a large semi to 50 or more for a moped. That would be miles per gallon.

Answer 3

Not always...

Depends on the car. For example, a new rav4 will get better mileage on the freeway with the V6 than with the 4 cyl.

In general, however, all of the cars that are in the "highly efficient category are very light weight (the primary factor in efficiency) and have 4 (or fewer) cylinders.

For a listing of the most efficienct vehicles (they are also the ones that produce the least amount of CO2, there is a linear relationship between gas mileage and CO2 emissions) see the following web site:

Answer 4

on some cars they do ,on some like some of the Chevy,s and a few other cars it has been proven that the v-6 engines will get as good and better in some vehicles,but in the majority of the times a 4 cylinder will get better mileage, a lot of this is based on the weight of the vehicle too,good luck.

Answer 5

As long as you do general maintenance on your car. Like oil changes when you are suppose to and rotating your tires, it will. My 4 cylinder gets almost 40 miles to the gallon. Its a 1998 Mazda 626. But my husband is a mechanic and he takes good care of it.

Answer 6

Most of the time they do, not because of the four cylinders, but because in most applications they are lighter and used in light cars.

If you tried to power a heavy car with one, it would be really dragged down in both power curve and gas mileage.

Smaller and lighter engines get better fuel use because they don't have to put out the power that the larger engines do.

Answer 7

no, there are cars with less cylinders. Gas mileage is mostly based off of displacement and type of aspiration, and effieciency, and how much work will be required of it

Answer 8

NOT ALWAYS THE CASE. SOME HOPPED UP 4 BANGER COULD EASILY BURN MORE FUEL THAN A 6, EVEN AN 8. WEIGHT OF VEHICLE, DRIVING HABITS,LOADS, VEHICLE CONDITION AND A WHOLE LOT MORE DETERMINE MILEAGE. I HAVE A 6 CYLINDER TRUCK THAT GETS LESS MILEAGE THAN MY '04 Z06 VETTE.

Answer 9

yes the lower the cylinder the better the gas milege. It takes up less gas to fire up 4cylinders than it does 8.

Answer 10

usually, but some older 4's are less efficient than some of the newer 6's.
