Hypermiling? What's your best result?

Question

I have been hypermiling for 2.5 weeks now. I drive a sport sedan 2.5 liter 4cyl. My blended EPA for mileage is 27mpg.

My first attempt I got an average of 30mpg for a tank, and on my second I managed a very nice 34.75mpg. I didnt do any of the crazy stuff like drafting trucks or taking wild turns but I have been coasting to stops, using cruise control at lower speeds (47-50) on the highway ect...

Whats your EPA and what is the best you have done? What techniques have you used?

Answer 1

I bought a motorcycle and got 63mpg out of the first tank and 61mpg out of the second (I had more fun on the 2nd tank). I only have to do 2000 miles a year with the bike to justify the extra insurance, maintenance and fees.

I'm saving about $10 a day in gas and I'm loving it.

Answer 2

I've just increased my mileage by 10%

I have a Ford Contour with a stick, and I've been turning off the engine and coasting for maybe a 1/2 mile, - and if the light is red up ahead, I wait as long as possible and pop the clutch, - to start the engine again. But sometimes I have to use the starter.

I drive pretty 'hard', and the Contour is old (209k). It's dropped to maybe 23 mpg. I've done these 'tricks' for the 2 weeks now, - and I just filled up my tank. I've recorded 25.62 mpg now. That's about a 10% improvement.

I'm getting better at figuring out when / where I can do this. Some times I can 'coast' for about a minute, - based on hills and such. And then again, my engine is not idleing at a red light for 3 minutes.

Answer 3

I have a Nissan Versa CVT, and just started.  I didn't have very good efficiency before, and got 29 MPG.  (Jackrabbit starts and 70 MPH.)

The first tank I tried hypermiling, I increased my MPG to 33.

I  reduced speed to 60 MPH when I could (the trucks have all slowed down to save fuel, so I can usually find a lane that they are driving in and not aggravate anyone)

I use the pulse-and-glide that is mentioned in my link, and otherwise coast when I can.  It's my understanding that with the CVT, I don't need to change to neutral, and maybe shouldn't.

I have always tried to drive in the space between bunches of cars on the highway - so this works pretty well for me.  When I get in heavy traffic, I just drive with the other cars and forget about it.

I may try the increase in tire pressure next, if it does not set off my tire-inflation warning light.  I am looking forward to seeing how much this helps.
