101 MPG segment for ZX2 at 32 degrees.

Old Reliable ZX2 did it again today. 11/17/2006

I believe noteworthy by virtue of being done at highway speeds.

101 MPG segment, 33 miles, 50 MPH avg. speed, 74 MPH max. speed.

ScanGauge Readings Below.



Weather not the most desirable today.

The general consensus seems to be that coId weather puts a virtual end to serious testing and FE. I decided to give it a try anyway. I blocked both front and rear of the radiator today. Had bought an engine block heater but didn't get it installed yet. Also added extra blocking at bottom of engine compartment. New 195 thermostat and new battery. This seemed to work well for getting up to temperature in 32 degree weather. I will make this run again on a nicer day.

Car is complete as sold new. Zetec DOHC Engine, 5 Speed transmission, Air conditioning, power steering, power brakes. Stock wheels and tires 185/65R/14.

Nothing missing on car, seats, spare tire, jack, small box of tools I carry, my wife, our cat & her equipment, on the road lunch, all there today.

We have had this car for about 4 years and the best mileage measured during that span was 43 MPG. The cheapo aero mods I have done cost practically nothing but produced a marked improvement in FE. I don't believe I have spent over $200 on the car otherwise including battery, block heater, thermostat, a 4X8 sheet of plastic, spun wheel discs, a couple switches and wire for shut-offs on the ignition and fuel injectors.

One notable exception to my cheapskate ways was to spring for a ScanGauge II. Paid $165 for it. A very important piece of equipment to me. I thought I was a pretty decent economy driver. WRONG!!!

EPA rating for this car 25 city 33 highway.

I got seriously involved in fuel economy in September, 2006. It has been since then that this car has transpired into what it is today. Since September 27, 2006 I have logged over 5000 miles FE testing. Average 53.25 MPG for those miles.

I hope this serves to inspire others who have taken up the fuel economy game.

Thanks for looking in.

Yes , cats can swim , but they usually dont because they look goofy when wet.
Yes , I can swim , I have scuba certification although that doesnt help here (not a very popular hobby)

Cats here are house cats , and I dont like the idea of that too much.
Some of my friends here have cats and they look dead and soul less ,,not like my Ozzie cat , always out having fun and killin some thing to eat.

I am looking for a used car right now. I didn't really consider the ZX2 because i thought it has a 2.0 and 130hp and a lower EPA. I figure i would only be able to get mid-30mpg with it. I guess not!

Amazing. ZX2 you are up to super-hypermiler status and you have only been here a week.

Thanks for the comments. I may have only been here a week but I've been around cars all my life. An ex-drag racer and a race engine builder for 30 yrs.

As I have said before we have gotten 40-43 MPG with this car ever since we bought it. I am impressed with the variable valve timing. Enables low end torque along with high RPM performance. I am positive that this feature contributes very positively to the FE of the car.

I would try to find a 5 speed if I were you.

seeing what you have been doing with the 5 speed make me think i should have waited and found one instead of the auto i got. oh well guess i'll just have to do what i can with it.

most of my driving is short trips to work and to town and take almost halfway which is about 2 miles for engine to be fully warmedup (180+ coolant temps) i have found torque converter lockup at 42 mph and once locked i can go down below 40 mph but soon as i back off gas fully it unlocks on me.

LXMike, good to hear from you. Are we the only two ZX2s on the site? We all have to just make do with what we have till we decide to do something different. If I had asked any FE freak if my ZX2 could ever be a good FE car, what do you think I would have gotten for an answer?

Do you coast in neutral? Your car start OK in neutral? You could probably make a heck of a difference in your MPG by considering these items. I would like to see you wire an ignition kill switch and/or an injector shut-off switch. Either of these will kill the engine without touching the key but I now prefer the injector shut-off. It has less delay when shutting down and you're sure no fuel is going into the engine. I have my switch taped to my gearshift handle till I decide where I really want it. Having this switch and the willingness to do Engine Off Coasting can improve your mileage drastically, both city and highway to coast hills, slowdowns, offramps, stoplights, parking lots, any place you can. A start pushbutton could be wired so you're not fumbling with the key and also keep the normal operation of your ignition key switch.

I do not mind that the power steering and brakes require more effort. Your brakes will have vacuum enough to make 3-4 stops before the pedal gets harder. I am going to rig an auxiliary vacuum tank that will make my brakes good for 3-4 added stops.

I think you asked me about my grille block in another reply. Look at the picture in My Garage. I just cut an oblong piece that covers the whole air inlet below the license plate. Then I used duct tape to fasten it. Then I masked up close around the outside edge of the tape and spray painted the panel and tape at once. Looks pretty good, and easy. I did the fender skirts the same way. If you decide to do skirts I could send you a pattern from mine. If you use squared off pieces for your panels, makes duct taping a whole lot easier. You don't have to deal with taping curves. If you need to change a tire you can just peel loose enough of the tape to do the job. I carry tape and scissors with me. Tape don't stick twice very well. You could
also use these tools for an opening in your grill block if needed.

I do not warm up my car before driving. Just drive sensibly for a minute. If you look at your SG2 GPH gauge you will see that idling cold uses as much fuel as going down the highway at 60 MPH.

It would be worth the effort for you to consider these mods. I can answer any questions you have and help you if you wish.

What were the winds like during your run? Colorado gets pretty windy at times, and if you were driving along with a 30 mph tailwind, that would have a great effect on your mileage.
