Record for my VX!
 

My typical driving style, I drive about 80MPH and get about 42-46mpg without trying on my 93 Civic VX.

If I start driving with mileage in mind, I can get 46+mpg. My record is 52mpg.

Well, this week I decided not to drive over 60mph, follow trucks for drafting purposes and to keep my speed down, and decide to take highway 101 over highway 280 (less hillls).

I'm not done with my tank yet, but let me say this, the VX responds well to conscious gas saving efforts.

With my typical driving style of 80MPH on the freeway, I get about 220miles before my gas gauge reads 1/2. Never mind that the gauge is nonlinear, I'm going to use it as a gauge.

If I drive with mileage in mind I can get about 240 or so before the needle hits the half way mark.

This week, I hit 307 and I'm at the half way mark!!!! I even took pictures! I've never seen that type of mileage at the half way mark.

It looks like I'm in for another 50+mpg fill up! I don't go over 50mpg much because of my typical driving style and because I have a CA VX.

Those with VX's, what is your mileage when you reach the half way mark on the tank?
Gary

You should add a garage and gaslog entry.

Welcome to the site!

Best I have got is 51.6 a/c on 100% of the time going 65-73 mph

my best tank with my 92 vx 57mpg
half way best 350 miles but the gauge is not accurate at all....

Done!

Do you have a CA or FED VX?
Gary

If you want to get good FE while driving fast, you'll need to aero-mod your VX. On an interstate trip last weekend (one leg at 75 to 80mph, return leg with more traffic at 70-75mph) I got 56mpg (526miles). I'm driving a CX with a DX engine. Since aero-modding the car, I get better FE at 80mph than I used to get at 60mph in its pre-aero days.

Maybe I'll aero mod mine some time. The VX aero modded would be something else. With your aero mods I think I could regularly get 80mpg basjoos.

Gary, I think my best 1/2 way mark was 300 as well. I wouldn't get too specific as it doesn't stay at any one part on the gauge for extended period of time. Sometimes half, sometimes a little over half, sometimes below half. Unless you are doing first time hit 1/2 was 307 miles, in which case you may take the new crown for best FE with a stock VX. :P

You'll notice making Right hand turns causes the gauge to drop and Left hand turns causes it to go up. Or is it the other way around? I suddenly can't remember.

Yeah when i hit bumps and make turns, the gauge will go down. I took that into consideration. I drive the flat hwy 101. If I hit a bump, I wait for the needle to settle and then determine where I'm at. I don't hit a bump and wait for the needle to go to the lowest or highest point to proclaim my high mileage mark. But definately, I was getting about 220 at the half way mark before and I'm at 300. I worked from home today so tommorrow I will have to fill up. I'll let ya know what I get. I'm thinking low 50's this time (I usually get a bit more than mid 40's mpg during my speedy drive to work with no effort on FE.

Fed Vx

You have pics? I don't want the car to stand out... It's a nice beater :).
Gary

Hey 1993CivicVX, can I proclaim myself as the king of stock CA VX mileage?

I got gas today and calculated 54.8 mpg!!! Thats with alot of drafting and about
95+% highway driving. Drafting really works. My best last time was 52mpg and I was drafting and going through the santa cruz mountains daily to/from work. Perhaps I could have gotten 55mpg if I didn't overflow my gas tank after two clicks.

I just ordered a federal VX ECU/ECM and I'm going to order the wide band O2 sensor to convert my VX into a fed one - I want lean burn!

If I didn't draft, the best I could do is around 48mpg.

Gary

BTW, I entered my last two fillups into the gas log.

nice one. :) Congratulations. I think you'll notice quite an improvement with the FED conversion. Once you get converted we can do a little competition. :P

Although if most of your driving is highway I don't think you will be able to get into the 60s (unless you do some hardcore tractor trailer drafting)

The reason I can get great mileage with little effort is because of where I live. Most people are happy to drive below the speed limit. And all the speed limits around here are 30, 35, 40 and 45mph. The few places that are 50 and 55 I try to avoid.

So imagine driving average speed of 40-45mph on the highway with pulse and glide. That is in effect what the majority of my driving ends up being. Except that I'm stopping a lot at intersections and what not and often doing short trips.

I think if you drive with your VX once it's converted the way you drove on this tank you will get 59mpg.

Gary,

i love the GMC Typhoon! what kind of shape is yours in?

It'll be awesome if I can get 59mpg! I just took a look at the gaslog of the guy who converted his CA VX and got 60+.. It looks like the times he got the 60+mpg mark is when he did a short fill. What I mean by that is that he filled up a tank when it was almost full. I guess what he did was fill it up, go about 100-150miles and then fill up. I don't think that's as accurate as running it down a tank and filling up.

I will draft more trucks next week and see if I can get similar mileage. I just pump up my tires slightly pass max so it'll help.

I can't believe I got almost 55mpg in a CA VX! Well, drafting was a major reason ...
Gary

It's in excellent shape, although it could use a wash. I had it since the mid 90's and it only has about 92k miles on it.

The truck is quick, but it's a brick after 100mph. Mileage isn't that great.. I get about 16mpg or so... but then, that's what my vx is all about... mileage and saving mula.. I take the truck out for fun and to the drag strip, not to save gas.

I love the typhoon too!!!!
Gary

when the cyclone first came out, i wanted one. now, with a family, i'd prefer the typhoon. but as you said, FE is not great, so couldn't afford either right now.:(

I got 56.21 mpg this fillup! This fillup includes a run through the santa cruz mountains (not good for FE). I drafted most of this week and got my first 450+ mile range on a tank (466 to be exact). On my way home from work tonight I drafted a semi. I decided to follow it the long way home since I had a good draft (a semi going contant speed in the same lane), but we ran into a traffic jam. I ended up in traffic for about 20 minutes and I took the side streets home with alot of stop lights. That killed my FE for sure, but I still managed 56.21 mpg!! I guess it helps now that I use the car 90+% on the highway.

In the 3-4 years I've own this car, I've recently been getting excellent mileage! I usually get mid 40's. The car was down for about 10 months due to a bad tranny (Oct 2006-Aug 2007). I changed all the bearings in the tranny (that'll help FE). I also smogged the car so I advanced the timing after smog which drops HC in emission at the expense of increase NOx (a definate plus for FE - my HC is only 9PPM at idle at 15mph which is lower than most VXs I've compared it to). I had a slightly clogged EGR system so I changed out the intake with another stock one that was not clogged. A clogged EGR system decreases mileage (a plus for FE).

I can't wait to get lean burn running on this car (CA vx)!

Gary

Through the years, I bought some performance parts for this truck I never installed, like two new turbos, fuel computer, and other stuff I can't remember. I still plan on installing them, but the typhoon is on the back burner now as I'm swamped with work. I love the typhoon, but with gas prices going through the roof and it getting about 16-18mpg I haven't focused on this vehicle. I'll probably do my vx ca to fed conversion before I touch the typhoon, but I still love that truck!
Gary

Nice one Gary. :) Looks like you edged me out for your overall gaslog, and you have the CA model. My next fill up should have me in the lead again, tho. :D

Thanks Jacinto!
I like the notes you left in your gas logs.
I'm attributing drafting as the main reason I'm
even getting over 50mpg. I wonder how much
better the lean burn will get me? If I can get 5mpg
more, I should be getting in the 60's mpg.

Hey I noticed you bought another O2 sensor. Is it the $79
from ebay? LMK.
Gary

Yep, it is. TomO emailed me the link to it. I guess the jury is still out on whether it's any good tho...

Have you seen this post from krousdb?

The vacuum guage should be fairly easy to install & would help increase FE.
