How's your MPG??

[jetdoc1971]

Been hovering around 23mpg with the waggin , L20 , 4 speed , bone stock. How is everyone else doing?

[datzenmike]

Hell I can get that on a trip with my 3,500 lb 620. I would think even a goon would get closer to 30.

 

I comes down to vehicle weight mostly. To a lesser amount, how you drive it, what motor size and power, the rear gearing, tire pressure. This assumes it's running well and in tune with fair weather.

1969 wagon, L20b with Shadbolt 445 cam, 38mm SU's dog leg 5 speed, 10.5L/100km or about 26.5 mpg....

[CharlieBucket]

i'm getting a little over 30 mpg with the b210, depending on the exact size of my tank. not quite the 50 datsun promised in the cool ads from the 70's, but better than most peaple. i think i am losing because i have reving it so much when it's cold. if i knew anything about carbs i'd adjust the choke. i'm slowly learning but with 2 babies i have little time to tinker with carburators. i plan on trying to get the a14 to it's peak mpg's.

620 with l20b and weber ...have trouble getting 20mpg

[Bleach]

the truck I used to have

 

L18, truck 5-speed, stock compression, Crane Cam, Weber 32/36 jetted down a little. 27-28mpg average

[420n620]

my bone stock 78 620 KC 5 peed gets in town around 23 mpg, havnt got it out of town yet, to busy workn on the other 620's :D

[Bugeye]

my bone stock 79 620 gets about 25mpg when I top off the tank

[Icehouse]

28 is my record with my KA 620, I think some better rear gears would easily get it over 30. My freeway RPM's are way to high to get any better milage.

My electric truck will go way over 100 miles on $4 of electricity :D

[DISLEXICDIME]

my stock 620 gets about 26 my dime with su's l20 a 5 speed and 370's in the back gets about the same

[mnementh666]

Getting about 20ish on cammed L20B in a 521, with the carb (probably running rich now) and 3.90 gears, 79 280Z 5-spd

[makya]

I'm getting 24-26 on the highway with the dually. 18-ish with a heavy load in it.

[datsunaholic]

31 in my King Cab, commute. Traffic and lots of hills, but 75% is 70MPH highway travel. Probably would do better if I wasn't carrying a wagon hatch and 2 spare tires with me. I put 6.5 gallons in tonight, full, after filling Monday (205 miles in that time- 2 days commuting). L18, '82 ZX 5-speed, Weber jetted for a 1.4L B210. It'll get 35 on occasion.

[DRIVEN]

In my 1200 coupe with the freshened up stock A-12 and 4 speed @40. After the dogleg swap @ 42-44. With the super tired A-15 and mikuni 4-pack @30-32 The carb tune is close enough. No use in fine tuning until the motor gets tightened up. I'll be shooting for high 30's. Maybe better with proper gearing. Roller skate sized tires and 3.90's don't help.

[hang_510]

:lol:

2dr + heavy lead foot = 15mpg :fu:

i got about 16.5 cruising on PCH over the weeekend

[MikeRL411]

Bone stock 1967 RL411 with 3 speed British Borg Warner. Really set up for production sedan road racing. Daily commute on city streets 20 MPG. Doing 60 to 65 on freeway 35 MPG. Never meant to be an economy car.

[datsunfreak]

L16, 38mm SUs, header, 2.25" exhaust, stock 4spd in a 510.

 

And I'm getting maybe 17mpg... :D

 

Methinks I need to lean it out a bit, dial some timing out of it, and maybe try to drive more conservatively.

 

Then again, maybe not... ;)

L16, 38mm SUs, header, 2.25" exhaust, stock 4spd in a 510.

1.75" exhaust. You'll gain power and fuel economy.... :blink:

[datsunfreak]

1.75" exhaust. You'll gain power and fuel economy.... :blink:

 

And it will sound like shit, too! That's a win/win! :D

 

Problem is, no one around here does pipe that small. On my last car I had to go to 3 different places to just find 2". 2.25" is everywhere, so I went that way.

 

And I know the car is eventually getting a KA24E and didn't want to do the pipe twice. ;)

 

The KA should solve my mileage issues, too. My last KA car routinely got 27-30mpg.

[bonvo]

76 610 stock l20b dogleg 5 speed last i checked it was getting about 16 mpg but thats cause i cant keep my foot out of it and it lives for the most part at 3500 rpm or higher :P

[datsunfreak]

Same here. I need to swap in a 5spd BAD...

[fiveNdime]

My MPG:lol: hah, I dont care about mpg's. It would help me anyway since I mostly drive about 4 miles a day round trip.

[]2eDeYe]
