Bested 40MPG on my work commute! - Fuel Economy, Hypermiling, EcoModding News and Forum

Normally this trip is what kills my mileage. It starts out with a steep downhill into an intersection with poor visibility where i have to yield and turn sharply. Then it's steep downhill again, and at the bottom of the hill a 19mph-zone starts. The trip is also a bit short (6 miles one way) which makes engine temps a problem. And traffic frequently gets in the way of efficient acceleration.

Lately however, it's been really warm and traffic had been lighter (vacation times). So last week i finally did it, 40MPG! And earlier this week i did it again, and today 41!

40 isn't difficult on longer trips, when i drove to the gym and back (about twice the distance than to work) i got an "easy" 48.

The trick? Rather aggressive P&G, my engine is either between 2000 and 3500 rpm on high load, or off. I EOC closer to 70% of the distance.

Nice work with the mx-3

I had one 3-4 years ago besides fe it's a really nice car!

It's off-topic but a great trick I found about these car is to install an oil filter from a corvette zr-1 from the nineties. The large oil filter will have less resistance and you won't hear your lifters ticking back 500km after an oil change.

What were the temperatures on this trip ? Did you engine off coast much on hills ? What other tricks did you use ?

I'd still love to get me an mx-3 someday, but need to know how easy it is to get at least the same mileage as i now get with my Civic.

Have you ever thought of tuft testing the car ? It sure would be interesting to see the flow on the back glass ( this could be a simple single person test - just prop the video camera in the back seat pointed at the back glass. )

Can't give you numbers, but as warm as it gets in Sweden in the summer, it's probably much hotter over there.

Same technique as described in my first post, just a longer trip.

I've considered tufting, but topside aero is just not a priority right now - i've got bigger fish to fry. (Such as bottom side aero, engine bay insulation, and possibly a VVO-burning block heater(no electricity where i park))
