Fuel Economy?

[DauTsun]

Hey guys, just wondering what kind of economy you are getting? I found out mine was about thirty seven MPG on the highway, going around 2000 rpms.

 

I have rebuilt my head, all new seals , and an EMPI Carburator. Is that good? or Bad?

never really looked into it. all i know is i can go an assload before filling back up. 2 or 3 days at work no problem. i deliver for a living. L20b webber and a fatory 4spd and stock 73 gearing. i turn 4k at 60mph....

Ok I must be doing something wrong... I get 16 in the city and 21 on the highway! I have 3.7:1 in the rear L20b and a five speed in my 79 620 O_o

mine burns half a gallon in 20 minutes just idling, but i need to adjust the float, and full tune up, the points are 20 years old lol, budget was tight this last year, but the build is about to take off,

I'm getting an average (fill tank, calculate and repeat a few times) of about 25ish on my tired old '76 L20B. 5speed tranny. Keep in mind its smoking and smelling of gas too. Doesn't smell as bad since I leaned out the mixture screw a little bit. My rebuild on the other L20 is waiting on the head...after that I'm hoping it will drastically improve. I also plan to take a stab at an HHO setup to see if its hipppy crap science or real. But that's another project once I get this truck running stable w/ the new engine :)

If you haven't replaced the speedo pinion then your really going further than the odometer is reading. You are going about 18.25% further than indicated. Or 24.78 on the highway
