What Mpg Are You Getting?

[BurninCB7]

I was getting 20 avg, then I changed my O2 sensor along with plugs, wires, rotor, etc... Also reset the timing.

Yesterday I got 22.75. This included half of the tank before the tune up.

I need to be getting about 25+... Thinking about a bump up in compression

On 10 gallons of gas I manage 300 miles which is about 30mpg. This is mostly freeway miles, I hardly drive city. But when I drive between 75 to 80 and accelerate up to 3k sometimes over. I have done a study when I went 60 for a whole tank and not over reving and got up to 320 miles.

I get about 300-320 a tank depending on how I drive. 80% city, 20% freeway. Our CB's have the low fuel light?! When I first got the car, it was choking and the needle was just under the white notch by the red. I ran out of gas one time. Where can I get that light back? The fuse?

I consistently get about 450 to a tank (14.4 gal) roughly 31-32mpg (90hwy/10city) on my 90' 4dr EX. I was getting 29 before I realized my PCV valve was junk. A simple 1.99 fix from Checker/Orielly and next tank jumped up instantly to 31~32mpg.

I also installed an AEM CAI (only mod). Before I was getting around 27, then that jumped to the 29. Most people gain 2-3 mpg just from doing this since the intake can breath easier.

My best mpg ever was on a strictly highway trip. I got 37mpg drafting cars at 85-88mph.

I also noticed that the mudflaps that came with my EX were causing aero drag, so I removed all 4 of them and I think that helped maybe 1-2mpg.

But this car also has a fairly new distributor, timing is dead on, and plugs/wires are new....well plug wires are from 03' (JY specials lol) a lot better than the original ones from 1990 w/ 250k miles that's for sure.

Its also a 5spd so that helps

Awesome! How much does replacing the stock hood and trunk lid with cf ones affect fuel mileage?

probably not much. it will certainly have a positive effect, since there is less mass to accelerate, but the cost of the hood will hardly make up the the gas you will save. i suppose if your car gets slightly better handling, you can take corners faster and use your brakes less, which is always good.

as for my cb7's mpgs: the best i have done is almost 350 miles before i got nervous and refilled my tank. this is a 92 lx 4 door f22a1 with a 5 speed manual. completely stock engine but a few weight reduction projects. mostly highway driving at about 65mph. at the time i was experimenting with adding a little acetone to improve mileage. it seemed to help a little, and my cousin noted more power in his jeep with it. it's hard to say if it actually helps, or if its just a placebo thing.

I've got 400 miles on 13/16 of a tank when I first got it. Drove all the way from N.C. to PA on 13/16 of a tank.

300- 320 a tank. in my 90 sedan. no idea when the fuel filter was changed. also, thats with a pretty harsh oil leak out of headgasket.

thats still not bad, definitely can get way more though.

Yesterday I had a day permit on my car so I could take it in for a safety, filled the tank. Drove 140km/hr to town 50 km away. Drove around town, being pretty hard on the pedal, Very hard at times. Then drove home at 120km/hr with a total of 175km for the day. Gauge went down to 3/4 tank full. I have yet to refill it to calculate mileage though. There were also periods of time when it was idling for a while.

I'll rewrite it over the next few days and post it.

Oh please do, I'll be looking forward to it.

well i did a experience in canada....since i got my car

2010-between 2011 of spring.....stock everything..no tune up

driving highway- getting 500km
driving city- getting 230km...

improvement...in mid summer and fall of 2011

Tune up....air filter(short ram), o2 sensor, battery, intake cleaning and seafoam,

running on steelies gave me a huge improvement
highway- 750km
city-400km

untill aftermarket rims degraded just a little plus other weight on!!
highway-712km
city-378km

degrading weight is best to improve fuel economy

When my car was bone stock (f22a1) I used to average 34-35 MPG freeway. I got 490 miles on one tank of gas. When I went to my H22a, completely stock, no upgrades, I got 27-29mpg and around 380-400 miles on a tank and that was always using 92 octane gas. My f22a1 I would use 89.

[Joey GT-R]

I generally get about 430mi on one tank. And that's going all the way to the fuel light. If I dug a little deeper I'm sure I could get maybe about 450mi out of it but that's pushing it. I drive 80 on the highway all day long. Crack VTEC maybe 3-4 times daily. And do a little bit of city driving as well. Maybe about a 65/35 split. All on a street tuned H22A with I/H/E. Gonna add that Bisimoto Intake Gasket soon so I'm hoping for maybe 450mi daily.

[Hitman Cody2130]

I got 180 miles on 6 gallons with 85% of that being highway driving and I did not get the fuel light coming on at 180. I figure a 30 MPG average is pretty darn good.

[JBradley500]

highway driving, between 65-80mph with cruise set, mixed with a couple of stop-and-go times because of car accidents... my cd5 got 33.xx mpg hand calculated. Id assume with a constant 65mph and no stopping, getting over 35mpg wouldn't be too hard. throw in a manual transmission and maybe even more.
