Gas mileage KA24E?

[Backfire]

About how much MPG should I be getting with me KA24E? It seems like the gas goes pretty quick, or maybe it's just me.

[neverlift]

well if you have not gone over the parts that make good gas mileage. I could list them but you probably know....

[Backfire]

well i was thinking of starting with the fuel filter. Any particular one I should buy like a 300zx or just use a stock one?

[nelson8708]

Get the 300zx one. It is less than the 240 one and it flows more. Still breaking in my newly rebuilt one but i get about 25mpg on the highway. With the old motor i got around 22mpg on the highway. A simple tune up and some sea foam will help the gas milage. Not to mention your right foot.

[Backfire]

any particular year of 300zx that i should buy? NA or Turbo?

Also how does the seafoam work? I know the lucas oil stabiler stuff is supposed to cause foaming in the SR's.

I get about 19-23mpg overall, Ive replaced almost everything and this is still the best I can get, so I just stoped worrying about it.

[skylinekin]

300zx tt and n/a fuel filters are the same.

[nelson8708]

as long as its a z32 filter. I should be getting better milage soon. I was having a hesitation issue. Turn out it was corrosion on the injector clips. Cleaned them off and it runs way better.

Sea foam is a product you but from autozone. You dont want your oil to foam up. It cleans out your injectors, piston tops, intake manifold and what not. I have not used it since the motor i just installed is new but i hear good things. Just seach sea foam.

After airing up tires to spec, I've gotten 27mpg, typical is probably 25.XXmpg. I love high mpg so my right foot is light and Im not in a hurry to get anywhere (which is funny because the only reason I found this sight is that I was searching for all the ways to get more power).

[Steev]

I am getting 21mpg with my heavy right foot(on my ka24de though, you should be pretty close to that if you drive like me)

I was getting 10.5mpg on the jeep I replaced with my 240 so I am still not over the "is the fuel gauge broken, it's hardly moved" feeling.

i dont even know....lol

Bump for this.............

[jmancini]

I've kept a mileage record since I purchased my '90 240SX in 1995 (yeah, 12 yrs):

Best MPG: 32Worst MPG: 19Average MPG (about 100k miles): 24

Of course, it depends on your driving style...lead foot or put-put?

[27RB240]

Well you guys I think I am about to get this Soch S13...I talked to the owner a few times and he said the car was good to go, its just that it uses alot of gas...He asked a mechanic what was wrong with it, and he or she said it might be an intake problem..But I concluded that it could be out of the following: fuel filter, spark plugs/wires, intake, or it could be some clogged lines or something..He told me that the car doesnt LEAK gas, it just uses alot (it runs good but sometimes it smokes when sitting for a while)..So thats the reason why I bumped this thread...If anyone has something to add/take away please let me know.I didnt wanna go out and make a new thread when there's a post already about it on the 2nd page...

I bought my 89 auto 250sx 11/06. Paid $900. Replaced distributor, wires, plugs, 02 sensor, hose's, fix loose/broken bolts exhaust manifold, gasket on valve cover, thermostat & sensor, fuel filter, air filter, tighten exhaust system, used a fuel cleaner(did not know how long it had been sitting), ran carbon cleaning stuff at redo of above parts, then again at 3k more at oil/filter change. Car runs great, i get 27 hwy and 24 city. Still have egr to replace and egr pipe leaks a little. car has 174k on it know and running strong, no smoke. This is my beater car, when i went to pep boys to buy stuff one of the clerks saw my car and wanted to buy it!

i'm getting like 10-15 mpg Partly becuse of my heavy foot Partly because of my straight flow Exhaust.

[hypertek_sideview]

you are stating mpg, but what are you getting in mileage per tank, when the yellow light comes on?? I'm trying to get a bearing because I feel my car is running rich. I had a '92 dohc that would get me like to 320-350miles a tank. now with this sohc i'm like at 300-315. I already changed cap/rotor,wires air filter. gotta change the fuel filter and spark plugs, but yah I want to compare this just in case I might change the o2 sensor as well.

[Soravia]

I have new Fuel Filter, Air Filter, Spark plugs, O2 Sensor, ERG removed.

I measured 30-33mpg on 90 miles (mostly Highway) trip while driving 65-75mph average on the 5th @ 2900-3200 rpm using 93 grade gas.

I might be wrong here. I don't know the exact capacity of S-13 fuel tank but I lost a quarter tank for the trip.Oh and mine is a KA24DE, sorry not SOHC.
