I would like to swap out my 10 gallon fuel tank for something a little bigger.
I can get about 420 miles per tank before I chicken out. I usually get gas around the 400-420 mark.

Will the 12 gallon tank for a DX or EX work? What would be nice is if I can get a 20 gallon tank. That could possibly up my range to 850-900 miles before I freak out about running out of gas...

Has anyone done this to their vx?
Gary

'93 Civic vx - totally stock!

The answer to that question is in my first post.
Gary

That amount of additional fuel would add a lot of weight to the car.

lol, I was just thinking about this. I could get 1100 miles with my identical car! I think it's funny no one is willing to humor the poor guy just because it's not something that would help his FE. If anything, it might hurt it. If I knew the answer Gary I'd offer it, but I don't. But one thing you'd have to consider is that your needle is going to be on E for twice as long, and you're still gonna chicken out too early, so you probably won't double your mileage with a 20 gallon tank. If you see my reasoning Gary. Wow, that felt like a click and clack response. Nice car btw.

IIRC, gasoline weighs close to 8 lbs. a gallon. So going to a 20 gallon tank would more than double the weight of the 10 gallon tank (taking in account the extra weight of the larger tank as well). Yes, the larger tanks from the DX and Si hatchbacks of the 92-95 era will fit in the VX and would be the least amount of headache to swap. But in my eyes the ~1.9 gallons you would be able to carry wouldn't be worth it.

The answer in his first post was that he could drive 900 miles on a tank of gas.
I think lugging extra weight around carries a bigger penalty than going to the gas station more frequently. I personally like being able to go 500+ miles on a tank of gas.

Forget about World Peace...Visualize using your turn signal.

Gary, with my '95 VX, I used to regularly trickle in 5 extra gallons of gas after the gas pump automatically stopped. I used to regularly get 700+ miles per tankful, sometimes 800 miles when I drove very economically. I don't know how it's possible to put 15 gallons in a 10 gallon tank, but I definitely did it, and it had no negative affects on anything (and no leaking fuel out of the filler neck or anywhere else).

I would need a manual to be sure, but there should be an extra gallon of two of capacity in the overflow bottle provided it has one and maybe another gallon or so in the gas tank hoses.

I have an 8 gallon tank, the smallest Ive heard of on a normal car, and I actually think its too big. I normally get about 425 aswell before I fill, but if I would have went the entire tank last time, I would have gotten 624appx.

A 4gallon tank would be great for me. I dont see the problem with stopping to fill up and it'd eliminate 32lbs of dead weigh.

Gary,

92 VX's have the 11.9 gallon tanks, and then Honda swapped to the 10 gallon tank. Check out this website http://www.civichatch.com/info/index.php

our honda n600 has a 6 gallon tank, and I don't see a problem with filling up every 3-4 weeks, I don't think there is alot of extra space under there from what I remember, but I supose you could get another gallon or so in, but if you really want to boost it, get a gas can and fill it up at the same time as you fill your tank, and make sure to use the whole thing befor you fill up again.

I think you should be able to, I know with CRXs you can swap the tanks around.

That said, how much gas are you using every fill up? What's your gas mileage like? If you improve your mileage you'll get the same result,

Darn, I have a '93 vx . Thanks for the info. A mechanic told me the thanks from the dx won't fit (but who knows, it's not like he tried the swap).

And for those who are asking me why I want to do it? I drive over 100miles/day. I have to fill it every four days.
Gary

Well, I'm trying to determine if you're being sarcastic, but there is no way you're gonna fit five gallons in there.

I filled up exactly 10 gallons once so I'm sure there is half a gallon extra (.5 gallon - perhaps that's what you mean).

Gary

I'm using about 9.5 gallons at every fillup. I'm getting about 48mpg (best of 52mpg). I have a CA vx.

I'm doing a 100+ mile commute/day.
Gary

Gee I must have a confused 94 CX cause my car has on numerous occasions taken well over 10 gallons even over 11 gallons so For my car I would say 11.9 gallons FACT. So for VX's and CX's all having 10 gallon tanks, I don't think so. Infact I drove 7 miles sputtering runnin outta gas to a station and filled it up with 11.6 ish gallons.
So take it for what its worth on the 10 gallon tank subject, some might but some(ONE) definitely DON'T.....
Try drivin past E but watch the gauge as long as the needle moves around you got fuel in the tank when the needle stops movin all together go fillup.
Well that's how my gauge works atleast.
Check my gaslog for gallons used.......

Their used to be companies which made auxiliary fuel tanks which went in the hole that the spare tire normally went into. If you went that route, you could probably get 50% additional fuel capacity.

I tried looking for one of those aux tanks a few years back but couldn't find one for our cars. Maybe I should buy a generic one and make it fit.
Gary

I'm so confused. At last fill up when i was empty i only was able to put in 8.5 gals of gas in my 92 VX which would put it at 10gal with 1.5 gals still left in tank. Now i can get a range of 450m tops and have new O2 and my buddy has 92 VX and he gets 600m trips = 12gal tanks. Something doesn't add up here.
Is it possible that some 92 got 10 gal and some 12 gal as that link says 93 got 10 gal and 94 got 12 gal....wth is going on!

I've put 12.84 gallons in my 11.9 gallon tank. I know there is extra space between the tank and the nozzle. If you check my gas log, you'll see I have routinely put very close to 12 gallons in my tank and over 11.9 gallons a couple of times. There's extra space that the specs aren't counting on these tanks.

I frequently had 500-600 mile tanks in my 95 VX. I had the 10-gallon tank. I had one tank of 680+ miles (77 mpg on the fillup). Spectra Premium makes a 13.5-gallon tank that will fit a VX.

The most I could fit in our 92 VX(canadian made/canadian model VIN), was about 10.5 gallons; while the car's passenger side was lower than the spout at the gas cap. So, level ground 10 gallons seems to be reasonably what this tank is. I have a hard time believe it is 'truly' a 12 gallon tank since it cuts off 2 gallons short. A true 12 wouldn't need 2 gallons of 'top off' near bone-dry. We're not talking about the normal 'top off in stages and potentially flood your EVAP system either).

THANK YOU ADDICT! I was and still am thinking the same thing, that MY 92 VX has 10 gal tank. One I filled it up to top with 8.5 gals while needle was on E so i figured another 1.5 as what was left inside. No way with 12 gal tank i would be on E. That's extra 3.5 which would be 1/3 or 1/4 of tank (depending what u think you have). NO WAY!!!

Sorry Arky. VX have 10 gal tanks so if you're sure you put in 12.xx gal u have custom tank installed by Chris.

Check my gas log. I've put well over 12 gallons in my tank. If Chris put a custom tank on it, that's great. The more gas I can carry, the further I can go!! A couple of extra gallons isn't going to hurt FE.

When you going to post some pictures of that jelopy, Seabass?

Eventually i will.

^Well, ya got me beat on paint job and antenna! lol, my VX still needs a bit of work. Ugh!

The tank in Arky's is the factory tank. I can't see any reason you couldn't put the larger tank in any year vx. The chassis are identical for the 92-95 hatchbacks as far as I know.

The US 92 VX has a 11.9 gallon tank. The fuel gauges suck. I have had 4 civics with that tank. They all read empty with about 3 gallons left. The 93-95 VX has a 10-gallon tank. I could overfill mine to 10.2 if it was bone dry.

Addict probably not. I took the pic from best side. My body work and paint needs some work done. Trust me
