I was not sure where this should be posted, so I posted it here.

I have a stock '73 240Z, I was wondering what kind of gas mileage I can expect?

I have not started to drive it yet. Still have to get the gas tank repaired.

I would guess low to mid 20s on the highway.

My 73 240 all stock 173,000 mi. is getting about 26mpg combined city and highway.

I have a '73 with no smog, 72 SU's, stock intake and exhaust('72 manafolds) and I get between 18 and 22 combined depending on my mood and the density of traffic. I have gotten as little as 16 and I always use premium gas. I have also changed distributors to a single point and removed all advance retard switching units, thermo couplings and wiring for the auto(rebuilt) transmission with impressive performance enhancments. Will need to rotate tires soon...

Hearing what you guys have to say makes me jealous! I have a completely stock 72 240z and im getting around 14-15mpg city/highway mixed. Perhaps im running a little rich? The car runs fine except i have to get it pretty warm before i can let off the choke. Normally I have to drive it around for 10 minutes with the choke out so it wont bog when accelerating. I have a crane xr700 electronic ignition and a p60 coil on the way to my house via ups right now. Hopefully this will help some. I'll have to change my mixture settings. BTW I just got the car a couple months ago and i love it, except for the really crappy wet traction. My suspension is shot anyway...

Sounds like you have the exact same car as me.. only had mine a week, but it also takes about ten minutes no matter what before i can turn the choke of.. which isnt to bad (until i forget about it being on), will probably have to change spark plugs more often, but would like to fix it. Could you send me a message if you get yer problem fixed? i'll do the same if i get mine fixed. Was thinking of adjusting the carbs, but i realized i didnt know jack about them, will soon enough... I love the car, i wish i would've bought one sooner..

Hmm, I am getting really bad gas mileage. I was wondering if you guys could pin point my problem.

engine specs:

-no smog equip

-oem electronic distributer (10 over and a 36 max. I am not sure what that means)

-msd blaster coil.

-my mechanic convinced me to use 20w50 oil. I think I am going to change back to 10w 30.

-72' SU carbs

-oem exhaust manifold

- I do have ac, but I hardly use it.

The car drives great, but I get 13-18 combined driving and I am getting 10mpg city. I love the car, but I hate to fillup as much as I do. It was not this bad before I had the work done on my car (exhaust manifold, new coil and distributer, oil change, and removal of air tube.)

please help.

ooops... repeat

Wow, you guys all do pretty good. I would have figured my EFI would do better than the old carbs, but I only get 17mpg tops on a good day.

The highest reading I've achieved in my 78 was 27.53 and the low is 19.08 under normal conditions. It dropped to about 17.5 when I had a bad EFI relay and 16.8 when I had a bad cold start valve. I know this thread is about carbed cars but I was responding basically to Hrududu

My triple Webers get 18 on the Interstate. Never calculated the in-town mileage. However, on a road trip to Atlanta, my friends 72 with the SU's got 1/3 better mileage than me. We were travelling together; if I got 12 gallons at a gas stop to fill up, he got 8.

With my old L-24 with many miles on her she clocked a steady 23 on the hiway and 19 to 20 in town. All stock engine accept for a '79 ZX ignition and Round tops with F-54 needles . '73 Z automatic . v12horse , What air tube was removed ? Gary
