hey i just bought a 2.4L king cab and i did not expect it to have alot of power in the first place but i thought it would have more than it does now. and for some reason i am only getting about 16mpg is that normal for my truck or shouldent i be getting more like 30mpg. my truck is in the shop right now and i am getting my O2 censor replaced btu if that does not help does any one have any suggetions for me.

If it's a 4wd probably 20-21 is the best you can hope for. A 2wd should get in the 23-24 range.

Bigger than stock tires, etc. will hurt mileage and also throw the odometer readings off to make it seem like you're getting less mileage.

A bad O2 sensor will kill mileage as well. See how it does once you get that replaced.

Also, make sure and change the fluids & air filter. The air filter can really bring mileage down when its dirty.

i already changed my air filter and i do regular maintenance on my truck so all my fluids are changed. my truck is a 4WD so maybe it should not get 30mpg but it should still get better than 13mpg and i have stock tire size on right now even tho that will change when i get some money. so i do not know what is wrong i hope the O2 censor will help.

with a 4wd the best your going to get is 15-18MPG. My 2wd 4cyl gets 18 around town and 25 on the interstate.

Also you have to lay off the gas with Nissan. If you floor it at every light a Nissan engine will eat you out of pocket. You pretty much got to take it easy all the time or your going to get 13-15mpg.

I am getting 20-22 in town, but I have a 87 HB Z24i

I was pulling the same when I was driving my 87 HB Z24 as well.

The NAPZ-Z engine's get the best fuel economy out of all of the Nissan 4cyl trucks.

now if it only had a LSD and a granny gear! it's a 2wd
