2.0 - 2.5 MPG gain 4 free

Hi, I just gained 2.0 MPG on the way to my last camp out and gained 2.5 MPG on my way back home; The thing that makes it good was it was free. I did not modify my Intake system or Exhaust system and I did not buy a computer chip. [no changes to vehicle at all] All I did was SLOW DOWN. I usually tow at 65 MPH and average 11.5 MPG; But by lowering my cruise control to 60 MPH I got 13.5 MPG on the trip south and 14.0 MPG on the trip back north. I also kicked it out of overdrive on inclines.
Anyone else out there that has increased fuel mileage, either free or cheap? At, or near, $4.00 per gallon we need any ideas and experiences you have to share with this forum.

I use the "P" feature on my automatic transmission

Seriously, I think before I get in the truck to go anywhere, if it is under 5 miles and doesn't require hauling, I will grab a bicycle for the trip. I live out in the sticks, so a trip to town is a minimum of 35 mile round trip. We have long been in the habit of only making that trip once every couple of weeks, now it has been stretched out to once a month or when I am passing thru on the way to and from my job sites.

Gas Mileage

Yea I figured that out when I bought this trailer.
Towing it home I got 14 MPG.
I also didn't go over 55 MPH. I was not very popular. It was the first time I had pulled a trailer that long and was nervous.
As my subsequent trips got faster the MPG went down.
The last rally I again went 55 and did the weekend on a half a tank of gas (here to Williamsburg, around town and back).
I was happy.

Great thread ROBERT and congrats on your post #1000!

We typically tow at 65 - 70 in the 65 mph zones. I will have to try out the "slowing" down on our next trip out. Every little bit helps!

Congrats on #1000.
We noticed a similar phenomenon when we went to North Carolina last fall, we got 14mpg towing Bertha when I drove at 50-55 mph.
I've been preaching the "slow down and save money" thing forever. For anybody interested, 50mph is the "wall", after which fuel consumption goes down fast. EPA fuel mileage testing is done at 48 mph for this reason. That's also why the national speed limit was 55 for so long.
I had documented several trips towing our Argosy in South Florida, where it is pretty much flat, and got similar results, towing from 55-70 mph.
If the national speed limit went back to 55, two things would happen:
1-"fleet" fuel consumption would drop by millions of gallons.
2-virtually every driver would die of boredom...

Thumbs up Light foot - Shorter trips

I have two cars, a Porsche and a SSR. They both get around 20 mpg. The MoHo gets 10. I only use these for pleasure. I also have a Vespa ( 75 mpg ) I use on a daily basis. I bought the Vespa for pleasure and as my MoHo toad but it has become my daily transporter.

My Spring trip in the MoHo was only 300 miles. Compare that to about 3000 the year before.

I also live on a lake and I traded my 150hp two cycle fishing boat for a 50hp four cycle pontoon boat.

You know what, I spend less on my total fuel bill that I have in the last two years and I don't miss a thing. It's kinda fun to screw them at their own game.

I worry more about the price of wine than of fuel! Now there's something that's hard to cut back on.

Am I becoming a green person? (gasp)

I don't mind driving 55mph at all. It allows me to relax more and pay attention to what I am doing as well as enjoy the trip more. I don't like to be on a trip somewhere and be in a big hurry. I feel safer at 55 and it does help with the gas mileage.

1K post congrats! I haven't tested the idea of slowing down yet but am confident slowing down will help. Thanks for the reminder.

Another freebie to save gas is to set the tire pressure on the tow vehicle at the highest pressure printed on the side of the tire. It lowers rolling resistence thus improving gas mileage.

That's kinda the way we feel about it, too. We're getting ready to buy a new family car. The old minivan is on its last leg after 200k miles and 10 years. We've pretty much decided to go hybrid this time round.

Going green is easy when there are reasonable (read: not outrageously expensive) alternatives.

Sure enough, I can verify that driving slower will save fuel, allow more viewing of the scenery, and reduce stress. However, it is the basis for "Diesel on My Tail"!
Oh, our 1995 minivan was showing problems with the trans, so we bit the silver bullet and bought a Prius. Green green, and green.

I'm joining in to voice support for slowing down to save gas and $$. Every article I've read that gives advice on saving fuel costs includes the 55 mph factor. I've been doing this for over a year now, can sometimes persuade my DH to drive more slowly as well, and I've recruited a few friends who now are cruising more slowly. Besides "free" gas improvement, I find that I am much less stressed on the road and yes, I really do pay more attention to the journey instead of just racing to the destination. In fact, I'm amazed at the traffic that swirls up to and then around me, all rushing and burning the gas that they then bemoan. It's better for safety (remember the 55 mph speed limits--brought down death/accidient rates until the faster speed was reinstated), would mean real savings nationwide while we are in this energy emergency/transition to something more economical, lowers the blood pressure (mine at least!), and gives you time to see the country you drive through. All good and green to my way of thinking. I encourage you all to join in reducing your speed limit, daily as well as trailering, to the 55-60 range! Perhaps if you do, or are already doing the 55, you could post here and we could see a forum movement take form! ~G

Another way to save fuel is by looking ahead, and letting a vehicle coast to a red light instead of braking for it last minute. Braking is nothing more than destroying pre-paid motion. This is one of the reasons that a slower pace uses less energy.
