Default gas mileage v6 vs. 4 cylinder

I am 16 and looking to buy a car. My dad keeps telling me to only look for a 4 cylinder because they don't use as much gas. How much gas in used in a v6 than a 4 cylinder?

The difference between my wifes accord and her now camry is 2 miles per gallom difference on the highway and three in town type driving.Some of the smaller four like civic and carolla get better milage but are lesss powerful anhd smaller.I have know people who had corollas that got like 38 on the highway. Certainly a big difference if your 16 and the gas goes backup to around 3-4 dollars a gallon.

Well it depends upon the car. Some are significant differences and some minimal.

Besides that tuneups and timing belt changes are more expensive with more cylinders.

Johnfrisco is right. Too many variables.

As a rule of thumb, yes a 4 cylinder normally uses less fuel than a 6. But not always.

Any engine that has to "work" to push a load is going to consume more fuel than an engines that "doesn't" have to work.

I.E.....a 3000 lb car with a 4 cylinder would work harder than a 6 cylinder pushing a 2500 lb load....with all else being equal. So in reality that may mean the 4 and the 6 in this case getting about the same mpg.

Proper tune and tire inflation also play a role in MPG. Also manual transmissions as a rule consume less power from the engine than an automatic which equates to better MPG.

FWIW I have a truck with a V6 that gets 20/26. The 4 cylinder version got like 22/28. But the 4 cylinder version was also a pooch. Not that the 6 offered much more power, but it did have just a little more grunt.

Start listing cars you like, then look at the listed mpg for each. Premium or regular fuel will make a bigger difference in cost than a few mpg difference.

If he insists on a 4-cyl, look at something fun like a Honda S2000, Mazda Miata, used Porsche Boxster, etc... then again, you're 16, so you might just want to get a Volvo.

Are you serious? You probably haven't paid insurance as a teenager!!!

There are some Volvos that are fun and they are peppy. Check out the 850R's. Tanks for cars and all around good performers.

all things equal an I4 will get better fuel economy than a V6, but all things are not equal. Some high performance 4's get worse fuel economy than a V6, usually while requiring more expensive premium unleaded to do so. (Honda's "K" and "F" series engines come to mind.)

Usually the 4 cyl will get better city mileage but will be closer to equal on the highway. The 4 cyl should be geared lower and will therefore spin at a higher cruise RPM than the 6.

The 6 might even be more efficient than the 4 on the highway at high speeds. I've driven the same car with a small 6 and a big 6, and the big 6 got 1 mpg better highway mileage @ 85 mph.

There are plenty of 4 cylinder engines with a good balance between power and gas mileage. It also depends on the type of fuel injection, displacement, automatic or standard, etc. A 1.0L tin can won't compare with a 1.8L, DOHC, 16 valve engine.

The are also easier to maintain, cheaper to fix, weigh less, cost less, and do get better mileage in stop-and-go traffic.

Well, if dad is setting the rules, he's probably paying the insurance. Besides, when is insurance on a 16 yr old male not high?

cls152, go get a Civic Si sedan- 4cyl, almost as fast as an S2000, safer with fwd and stability control, lower insurance and cheaper tires. Other options would be a Mazdaspeed3, Golf GLI, or Nissan SE-R.
