if so, do you guys really get 40-50 mpg?

 

i dont have one but an aquaintence does...the gearing is nuts as in 50-55 mph in 3rd gear just cruising...and yes 40 mpg is about right. crazy cars...vtec-E for economy

 

yea, the max speed in third in a vx is 111mph, while my si can hit 88. i get like 30mpg usually, so those numbers are very possible, esp. w/ the vtec-e

 

I got one, it doesn't do 40-50mpg right now, but that's cos i can't fork out $400 for a new O2 sensor

 

I have a 92 VX. I always keep track of my mpg. I average 38-43 mpg. it has over 140k miles on it.

I don't drive like a granny..i like to take off at green lights once and a while..but other than that, i drive pretty conservative. If you shift when the shift light comes on, you'll do good.

 

I know you asked about the VX, but I have a CX that gets between 38-40 mpg when my wife drives it and 40-45 mpg whenI drive it. I hit 46.1 once. Completely stock, no mods.

Same here too...though I actually hit higher @ 48mpg - I couldn't believe it and thought the pump just shut off early, but I filled her till she spilled, so the mileage was right.

40mpg, 87 octane, and uses a $125 O2 sensor - golden.

the vx has a shift light stock?

 

The CX I had that was stolen had a light in the cluster but it didn't work. My gf brother has a 90 CRX HF and his has a shift light.

About the gas milage, my 92 CX that was stolen, I used to get about 40mpg consistant. It was stock, no mods.

 

I think the VX mileage rating would only apply to VX models that are either new or in very good condition. I believe the O2 sensor is the most important in retaining your mileage. And considering it is a wideband sensor which are known to not last as long as a narrowband, having a bad sensor can reduce mpg like my VX. Another factor contributing to mpg can be good amounts of carbon buildup througout the engine further increased by the EGR system that is present in the VX models.

I have a VX w/180k miles and the check engine light was coming on due to faulty heater signal from my O2. I ended up around 35mpg on the average.

Since my b16a engine swap, I've gone from truck gearing to motorcycle gearing. Quite a change.

Also have a nearly new(around 500 miles) VX O2 sensor if anyone is interested. It is the Bosch Wideband adapted to the NTK/NGK connector and works fine.

 

While we had it on the road (not in race trim), our VX got an easy 45+mpg using the shift light.

On the other hand, my built GSR swapped DX gets about 32-33 on the highway.


It's all in how you use the right foot.

 

Driving from SC to MD I got 47.7mpg traveling 70-80 mph with the ac on. Normal stop and go driving ranged 30-38 mpg.

 

yea, the VX came with an "economy shifting" shift light. It looks a like a green turnsignal, but it points up.

oh, i forgot to mention, my 38-43 mpg VX has only an intake and axle-back exhaust. The car came with a new O2 sensor when I bought the car used a while back. I have 14" alloys with meaty tires..and its lowered, but i dont think that'll effect the gas milage.

I don't really see any use for intake or exhaust on a VX unless it is strictly for replacement purposes. As for 14" alloys, depending on how heavy and wide they are, can contribute to the overall fuel economy, although it might be negligible.

VX owners should also check to see if they have front lip, rear diffuser, and front half radiator block off shield. All of these things can contribute to fuel economy, especially if you're trying to ring every ounce of it out.

 

i have a cx with a strock b-20 w/ a gsr tranny and i get over 30 miles to the gallon, including the occasional race

 

if you acually shift when the shift light comes on , and the car is in good shape then yes

 

With my del Sol SI, I have got 41.2 mpg before, and thats with it running rich, and a intake and huge exhaust

Now I have a GSR swap, with stock exhaust, gutted cat, intake, VX civic front lip, lowered, and lighter then stock wheels and tires (lowering + lip + lighter wheels= better gas millage) and I have got over 36mpg with it.

If I can get 36mpg with a b18c1, and 41mpg with a d16z6, I sure hope you can get 45+ out of a VX
