So i haven't seen this topic recently, how are the 1st gen with fuel economy?

I read they are around 20-23 mpg depending on driving habits, i also read online some guy who was able to get around 32 mpg with some modifications , like a WAI, oil catch can etc. http://www.gassavers.org/f72/32-mpg-...gon-13521.html

I am looking to get the most MPG out of my B20Z2 engine , any ideas?

thanks!

 

I'm also planning to increase the mpg of my crv. I just bought it wednesday though, so I haven't gotten an mpg calculation to start with yet. Lol. In to hear ideas, but I have a plan forming already

 

I usually get between 25 and 26.6 in my '01 5-speed but I've gotten as high as 28.6. The only mod I have is a muffler so this is all dependent on my driving habits

 

Around town I get about 18-22mpg, has had a recent tune up, just the 2 mi I drive to work doesn't bode well for fuel economy. On my trips back home from through Mountains of WV to VA I have gotten 27mpg for the whole trip.

 

that person who modified the CRV is me.

After a full year of experimenting, the only mods i kept were an intake that draws air to the stock airbox from in front of the radiator thus eliminating the resonating chamber of the OEM intake and the addition of an Ultra gauge to monitor my instant fuel economy.

You will not see any better improvement in MPG's than changing your driving habits...period, end of discussion. Our CRV's are big, non aerodynamic hogs with too wide of tires and a poorly geared transmission for fuel economy.

the b20 is under powered for the CRV platform thus requiring gearing to be setup such to maximize drivablity with fuel consumption. If we had a v6 or the likes, we could have a transmission geared to run at 1500 rpms or so on the highway. But unfortunately for us, running at 1500 rpms in 5th gear results in no torque to accelerate even a small amount. Catching my drift?

I have not experimented with skinnier tires but what I have found based on 9 months of experimenting with my 92 civic VX is that switching from 175 mm wide tires to 195mm tires yields a net loss of 10 MPG's with is roughly 23% of my fuel economy. If you apply this to the CRV, adding skinnier tires could increase your MPG's from 23 to 28 MPG's.

Our CRV's have too much ground clearance and might as well be shaped like UPS trucks. they are an aerodynamic mess compared to the gas saving CRX's, Civics, Prius's and the likes. Aero mods my do some to help but I did experiment with grill block off plates, resulting in negligible gains or somewhere around 0.5-1 MPG overall

hope that helps. I drive 120 miles per day so I have plenty of time for these experiments and reap the benefits of MPG savings much more than most average commuters.

 

^ I like you. And you are right on the $$.

 

This is awesome!! I read your story on that website i posted and i got to thinking about MPG's and getting the best MPG available!

Right now i am getting maybe 20-22 mpg around town driving slow and not accelerating quickly off a stop. I do howver have heavy wheels which the wife absolutely loves ( i would prefer the stock wqheel size with skinnier tires ) so i have to find other ways to get the best MPG i can.

I will try to experiment with backing off timing from the distributor , and trying to somehow lean out my a/f mix by maybe adding a line of propane if going on long trips ( not sure yert how i could do this though lol ) ...


Gonna research ... Google, here i come!

 

I got 29 stock I get 27 every single tank now with bigger tires. 215/75. I went from stock steels to oz racing alloys though i think that's helped me over people who get heavier steel wheels with big tires. didn't add much weight and I think it makes the final drive a little more highway friendly.
no engine mods, it is all driving style. and 5 speed makes a difference I think. I have always had the habit of coasting, a lot. I have been getting 26mpg driving my 350z with double the power and 2 extra cylinders. 6th gear helps some, but driving habits really are the best mod.

 

I normally get around 500 kms (310 miles) to a take. I only have a intake on my CRV.

 

From what I've noticed ever since I've changed wheels on my VCR, my MPG has gone down by about 1-2. They weigh a bit more than stock, but they sure do make it handle better. I have started changing gears from 2500RPM to 3000RPMS also. I used to get 26-28MPG average. Now I'm getting 25-26MPG. The horror!

 

This seems to be average.
I find, even with a heavy foot, I'm able to achieve this.

 

On a '99 EX I get about 340-350 miles on a tank. Only mod is a K&N drop in filter.

 

Mine is a 98 so I have 20 less hp then the 99-01s, and mine had 453,xxx kms (282,000 miles) on it. So I'm getting a little bit less then what I would if it was new again.

 

31mpg on a dyno tuned boosted/vtec crv..
99 ex 5spd, tuned on crome(1king tuned/wired electronics)

on my 2 vtec converted Vs before, 165miles on a half tank..
5speed too!

on my autobox 99, the most i got was 200miles on a half tank(hway),
same amount i put on twice while i was heading to pocono,PA

97 auto, crappy.. i might have a leak somewhere or needs better tune up!>?!?
150miles half tank....

 

Autos use more fuel anyways, that's just normal.

 

I get around 33 mpg. But I have a B18C swapped in.
