View Full Version : New 08 Civic owner. The ways of hypermiling for me?

Greetings all, found this website earlier today and im really intrigued by the idea of this hypermiling as I "thought" I was doing it for years but apparently, not good enough, so maybe you can give me incite into how to do a better job for my particular driving habits.

On April 12, 2008 I picked up my first new car, a beautiful 08 Honda Civic coupe EX-L. I"ve been wanting one of these for over two years since they first came out and at long last, things worked out to my favor and I traded in my 04 Honda Accord EX V6 coupe and now own "Silver Ice"


I live in the Rocky Mountains, specifically Missoula, MT where the roads are rough and the other drivers are even rougher. We have some of the worst drivers in country and not to mention a vast majority of people driving SUV and Subaru's for their type of lifestyle and driving habits.

Needless to say, i've been trained to be very alert and quick on the pedal for both brake and gas to keep outa harms way in my town. My current job allows me to work from home and use a company provided van and gas card so I do not use Silver Ice for work related reasons.

That being said, 98% of the time, I am driving in town. Being in Montana, our weather changes constantly. One hour it can be 40 degrees, blowing wind and cold rain, the next hour it could jump to 60 degrees with sunshine and no wind. The winters here get very cold and harsh, with variable temperatures ranging from -20 to 40 degree's that changes constantly, with snowfall, ice, hail, fog and everything in between.

Summer and springs consist of random rainstorms with summer becoming very hot at times 80-100 degrees with little humidity until fall sets and and cycle repeats itself

So there are times when I drive no more then a block away to the grocery store on a cold engine and drive for no less then a minute, park, do my thing and then head back home. Other times, im taking the 45mph sections to the other side of town which can result in alot of stop, crawl and go driving. At night I have more smoother and constant driving with less traffic. I drive from anywhere from 2 to 20 miles a day. My rough yearly average is less then 5,000 miles a year.

Our traffic in my town consists alot of stop and go, small side streets and a few sections of 45mph 4way roads around 5 miles long. There is also a decent amount of hilly roads that are around a 10% grade.

I also take side streets which average 20-30 mph and do require a fair amount of intersection stopping and going *I usually roll through stop signs, I hate full stops*

I only use highways maybe 2% of the time of my total driving, so the car is hardly ever at 50mph+ speeds.

That being said. I'm also planning on switching to full synthetic oil and possible 0w-20 oil to help my engine with colder temperatures and better fuel economy.

What are the suggestions of the guru's of the hypermiling for me? Also, keep in mind that I still have the thicker factory break in oil. They recommend not changing it till at least 4,000 miles so my engine is also not broken in completely yet either

freezebyte' Nice looking car. I drove buy your area on my way to Yellowstone last aug. Beautiful country. Had a few forest fires and it was very smokey. Looks like a great place to live? H:Dl

Hi and welcome to the forum. You may want to start with this article (http://www.cleanmpg.com/forums/showthread.php?t=1510) if you haven't already read through it.

Also, make sure your tires are aired up to the maximum pressure indicated on the tire’s sidewall.

Ya know I am noticing a general theme that everyone seems to think they have the worst drivers. Yes, bad driving is a national epidemic. But seriously, go watch drivers in Mexico or Greece or something. Ive always been an aggressive driver, but those guys make me want to crawl in a hole.

Freezebyte, that is a great looking car. You should be able to get some pretty good results from it - start with that article that atlaw4u linked to.

Apparently my civic has a fuel cut off system when I release my foot from the gas pedal, so Im wondering if my coasting and gas savings from switching into N is even worthwhile. Any incite?

Choosing between a NICE-ON and DFCO (neutral coasting and fuel cut) depends upon what the terrain is like and what is up ahead. If you going down a steep hill and will gain too much speed, use DFCO. If you are going to have to stop, use DFCO. If you want to coast for long distances, use NICE-ON. There are some nuances but that is the general guideline.

Hi Freezebyte:

___When you are at speed and coasting down, N will be far better than fuel cut because fuel cut forces the engine to act like a compressor to slow you down. Great for those occasions when a light caught you and such but if you were to coast down in fuel cut, you would have to reapply the accelerator pedal to get back up to speed and than cost down again more than a few times to make the same distance as a NICE-On would allow. You sue fuel cut when you have to stop. You use NICE-On’s when you have some distance to work with and possibly never stop.

___Good Luck

not to be flip, but if you have a block to the store, why not take advantage of the opportunity to get outside and walk there?

Errr, could someone elaborate NICE-ON for me?

NICE-ON is just coasting with the engine still running but the transmission in Neutral.

(Neutral Internal Combustion Engine - On)

I am doing that when I just need a few things, and im starting to walk to my YMCA to go swimming. Beyond that, I drive across town to Super Wally world for major groceries.

I've managed 50+ mpg trips of 4 miles or less... But, it's just a little more difficult to manage - you're one unneeded pusle, one long idle, one fast acceleration away from blowing it.

Actually, the other day I managed a 70.x mpg trip over approximately 5 miles. Granted, this wouldn't have been possble in traffic. I'd recommend these short hypermiling trips be taken when there are fewest people on the road so you have the most freedom to exercise the techniques to their fullest extent.
