I believe that it is somewhere around 16city 27highway for the manual transmission.
I own a 1978 280Z and get 6 to 8 MPG, of course maybe the 383ci 465HP v8 might be the reason........
The 1975 Datsun 280Z typically achieves around 18-24 miles per gallon (MPG) depending on driving conditions and maintenance. City driving generally yields lower MPG, while highway driving can push it towards the higher end of that range. Overall, the fuel efficiency may vary based on factors like engine condition and driving habits.
Per the 1976 Datsun brochure (280Z and 280Z 2+2):Federal emissions:16 city, 27 hwy (manual) 17 city, 22 hwy (auto)California emissions:17 city, 25 hwy (manual) 17 city, 22 hwy (auto)
Usually around 25 or 26 mpg. I have a 82 280 zx and on my best weeks i would get around 26 mpg . I drive 115 miles round trip all highway miles every day and dont get much better.
It depends on the size of the motor!! 231ci to 403ci..............
50 mpg for diesel
I own a 1979 GS 550L and regularly get 45 MPG, sometimes a bit more.
15 mpg
12 mpg
There are a lot of factors to this. Gears, engine, carb. But if its a stock 350ci with 4 barrel carb i'd guesstimate at around 12-16 MPG.
19 mpg city and 28 mpg hyway
