Dice T Posted July 8, 2011 Report Share Posted July 8, 2011 I recently aquired a completely stock immaculately kept 1973 240z. It has the stock L24 engine if anyone was wondering. So does anyone on ratsun know the city/highway mpg for 240z? Quote Link to comment
Eagle_Adam Posted July 8, 2011 Report Share Posted July 8, 2011 its called google - use it :P 2nd thing that came up what i put in "city/highway mpg for 240z? " was a wiki page; - skip to the end for you answer 240Z Datsun 240Z Manufacturer Nissan Also called Nissan Fairlady Z Production 1970-1973 Engine 2.0 L L20 (JDM Fairlady Z) I6 2.0 L S20 (Fairlady Z432) DOHC I6 2.4 L L24 (240Z) SOHC I6 Transmission 3-speed automatic (1971 on) 4-speed manual Wheelbase 90.7 in (2,304 mm)(2 seater) Length 162.8 in (4,135 mm)(2 seater) Width 64.1 in (1,628 mm) Curb weight 2,355 lb (1,068 kg) Designer Yoshihiko Matsuo 1970-71 Datsun 240Z Series I (U.S. Model) in color code 907 Racing Green 1971.5-72 Datsun 240Z Series II (U.S. Model) in color code 113 Green Metallic The 1970 240Z was introduced to the American market by Yutaka Katayama, president of Nissan Motors USA operations, widely known as Mr. K. The 1970 through the mid-1971 model year 240Z was referred to as the Series I. These early cars had many subtle but notable features differing from later cars. The most easily visible difference is that these early cars had a chrome "240Z" badge on the sail pillar, and two horizontal vents in the rear hatch below the glass molding providing flow through ventilation. In mid-1971, for the Series II 240Z cars, the sail pillar emblems were restyled with just the letter "Z" placed in a circular vented emblem, and the vents were eliminated from the hatch panel of the car. Design changes for the U.S. model 240Z occurred throughout production, including interior modifications for the 1972 model year, and a change in the location of the bumper over-riders, as well as the addition of some emission control devices and the adoption of a new style of emissions reducing (and performance compromising) carburetors for the 1973 model year.[1] The 1970 models were introduced in October 1969, received the L24 2.4 liter engine and a 4-speed manual. A less common 3-speed automatic transmission was optional from 1971 on, and had a "Nissan Full Automatic" badge. In 2004, Sports Car International named this car number two on the list of Top Sports Cars of the 1970s. One of the most appealing Japanese cars ever produced, it nevertheless disappeared almost entirely from American roads within two decades, presumably because like most Japanese cars of the time it had insurmountable rust issues.

ggzilla Posted July 9, 2011 Report Share Posted July 9, 2011 Can't trust a wiki! Go directly to the source, the government 18/24 Quote Link to comment
mike Posted July 9, 2011 Report Share Posted July 9, 2011 Has anybody ever recorded the difference in MPG from the gas "back then" to the "gas" now? I know the ethanol makes a difference as well as the lower available octane. Quote Link to comment
ggzilla Posted July 9, 2011 Report Share Posted July 9, 2011 Octane is the same back then to today. Regular is still regular. Ethanol is limited to 10% so doesn't affect the fuel economy much (less than 5%). Quote Link to comment
Vitamin Pepsi Posted July 19, 2011 Report Share Posted July 19, 2011 I get pretty damn good MPG on mine. Fifth gear at 40mph most of the way to work, gotta be near 28mpg or so Quote Link to comment
Skib Posted July 19, 2011 Report Share Posted July 19, 2011 it depends on your carb tune, engine condition, trans and rear gears, your driving style and the roads/speeds you drive on/at. any numbers quoted from 1973 are no longer accurate because your motor/trans are no longer brand new.

datrod Posted July 24, 2011 Report Share Posted July 24, 2011 Who freakin cares. It's a 240 Mod it up and drive the piss out of it. I once had a guy tell me after I put triples on my 240. (That's really going to hurt your MPG.) WHO CARES!!!!!!!!!!!!! :lol: Quote Link to comment
DRIVEN Posted July 24, 2011 Report Share Posted July 24, 2011 My dead stock '71 got a consistent 25mpg @ 70mph with a 4 speed. Quote Link to comment
Vitamin Pepsi Posted July 25, 2011 Report Share Posted July 25, 2011 I tested mine today, got 28mpg, without any attempt to save gas. I likes! Quote Link to comment
qwik510 Posted July 25, 2011 Report Share Posted July 25, 2011 My LS1 powered 240Z consistently gets 30+ MPG on the highway in 6th gear. Quote Link to comment
datrod Posted July 25, 2011 Report Share Posted July 25, 2011 My LS1 powered 240Z consistently gets 30+ MPG on the highway in 6th gear. Now that's just wrong. To have that kind of power and get 30+ 1 Quote Link to comment
qwik510 Posted July 25, 2011 Report Share Posted July 25, 2011 Now that's just wrong. To have that kind of power and get 30+ LOL! I agree. Mid 12 second 1/4 mile times, hangs with vipers and porsches on track days and 30 MPG. Something seems off. :lol: Quote Link to comment
blue72 Posted July 25, 2011 Report Share Posted July 25, 2011 There was once a discussion or two on HybridZ about this. Found a link to one of them: http://forums.hybridz.org/index.php/topic/81858-how-much-miles-per-gallon-does-your-z-give/ Plus, another on classiczcars.com: http://www.classiczcars.com/forums/showthread.php?30380-Mpg....
