New guy from Houston ('94 Corolla 5-speed with 13k miles)

Very nice job!

This bodes well for what I have planned for the Corolla I'm looking at. I plan on ditching the 4afe for a 1nzfe, aka echo motor. Should be a good result. Beyond that, there are a few other things I want to try with 1nzfe components.

Wow, you might have gotten a factory freak.

Hello,

I have difficulty understanding how a car can do over twice the EPA rating without mods. Something is out of kilter here, I'm wondering if the correct EPA reference has been taken. Does you speed of 55-60 correspond with what is known of the Corolla's sweet spot ? It seems a bit high for me so maybe there is even more efficiency to be gained from dropping that down slightly.
Hats off for all the hypermiling efforts but this story is just tood good to believe at first read.

Best regards / Colm

Impressive! However, I think a Corolla can´t yield over 50MPG in any way.
Use MPGuino just for comparative reference. Measure fuel yield based on liters to full the tank and real distance in miles. Check with a GPS and Google Earth.

Sounds interesting - I hope you post a project thread if you do this.

Oh, some healthy skepticism arises! It does seem incredible, doesn't it?

I wish my mom still had her similar Corolla - I would definitely have an MPGuino in it to do a speed vs. fuel consumption chart. (Of course, those stats don't apply if you're doing pulse & glide / burn & coast type driving.)

The fuel economy history for this car is posted, for those who want to dig deeper:



I certainly think it's within the realm of possibility to get this mileage from this car, but I'd think it requires you to throw lots of driving technique at it.

Let's not forget PaleMelanesian regularly gets 65+ MPG (US) from his Civic sedan - a roughly similar vehicle & vintage to this Corolla - by throwing every technique in the book at it, plus some mods.

The most obvious question a skeptic might ask: have you calibrated your odometer?

95% of my drive is highway. I also altered my driving times to miss rush hour traffic both ways on my commute. The highway I drive has been resurfaced so its smooth as a babies %^&. I check my tire pressure bi-monthly. I maintain throttle possistion on the few small over passes. The rest of my trip is straight and FLAT. being on sea level i dont think hurts. I look way ahead on the road to allow me adjust spped to road conditions. This allows me to drive with out breaks while in neutral and keeping some forward momentum. Sometimes if I can judge it right I will EOC up to the slow down and then bump start it to keep going. Drafting the big trucks. YUP in a heart beat. (no flamming on this. I know the dangers and it is my choice)

I have tightened up the nut behind the wheel to the point that my boy dont want to ride with me anymore. If we go out as a family (me, him and the woman) I am not allowed to drive.

I have tried different driving styles and changed my points of referance for EOC, P&G, different speeds, shift points, kinda anything I have read that has helped anyone. I have tried. This is the reason for my jagged edges in the fuel log. Some of the things have worked some of them not so good results. Like this week will be way lower than normal. I had to make two trip to Texas Childens Hospital this week. It not my normal route and is on the complete other side of Houston than I live on. So I drove like the rest of the population. Plus because of the situation I drove 70-75mph and said "screw MPG's I am going to the hospital"

Weather is another big thing in my area. our "winters" dont get beloew freezeing for more than a few hours. So we dont have the winter mixtures like some of the other parts of the country. Summer time it will be 80 degrees by 8am by 5 its over 100. We all know that warmer the air the better FE is.

My ODO is fairly accurate IMO. I have driven my 07 Dodge and my Company truck (Thats DOT inspected) and only see about a .2-.5 differance in the total miles driven for the week.


-Smallcog- yes it is hard on the first read but at least it is a short one. But i have not keep up with this thread like i should have. Thats my fault.

-MetroMPG- You are right it takes a lot of technique and consentration. Somedays I am more tired from the drive home than the full day of work i just left. Somedays I question why I am even doing it and should just go back to driving like the rest of the population.

Now I guess its PaleMelanesian turn to justify his off kilter numbers.

P.S. I forgot to add in my mods list that I am heating up my fuel before the rare earth fuel magnets. I put the twin tip spark plugs in (indexed of course) with the cyclon turbonator behind the air box. I also add a working HHO and for the added bonus I installed the DCD kit from Heihetech. Piece, Love and Chiken grease.

[schwally]

Can I see pictures of your HHO installed? Or were you being sarcastic?

[MetroMPG]

Sarcasm is a safe assumption.
