Default The Ultimate MPG thread.

Sooo.. I am making a massive thread dedicated to MPG... Tips on getting the best bang for the buck. I ask if you have anytips post them up. Or any links... I will keep this thread update... And will delete the BS.

Post 21 and 22... Otto's post very informative, be sure to check it!!!

TLDR: higher octane doesn't improve mpg nor does it automatically add power. Octane is a measure of resistance to ignition of the fuel. Higher octane allows higher compression. Modding for MPG is kind of pointless.*

Keep RPMs below 2000 as much as possible and MPGs start to drop very fast above 70mph. I also try to let my truck overdrive or fourth gear as much as possible (for mine it shifts around 41 mph)

Since where I live all things are measured in metric, I found this handy little website to convert litres/100km>MPG
Fast and easy.
http://www.calculateme.com/cGasMilea...G-imperial.htm

There is also one to convert to US gallons as well.

Coast a lot, dont gas it all the way until you use your brakes, begin coasting way ahead when you see the light change yellow, or a stop sign.
take it easy on braking, don't brake in the last 5 feet only. Easy on the pedals is easy on the wallet.

I definitely like the "under 2,000 RPM's" comment. I do that most of the time, and it does help out. However, the greatest MPG booster, for me, is the EDGE Evolution programmer. Though any programmer would probably do close to the same statistically speaking, EDGE is my tuner.

Let me tell ya'll a little story. From mid November to mid December of last year I made about 14 or 15 trips from my home in Oceana, WV to Covington, VA (around 230 miles round trip). My truck is an 09 SCAB with 5.4 and 3.55 gears and the trip was about 40% two lane roads and 60% interstate. I started out on my first trip with the cruise set on 72 mph I averaged around 16 mpg (on the computer). After a couple of trips I dropped down to about 67 mph and got around 17.4 mpg. 60 mph broke the 18 mpg barrier. On one of my last trips I sucked it up and set the cruise on 55 mph and got 19.6 mpg! Now keep in mind that I am driving in WV and VA and there are no flat roads. The terrain here is continuous up and down. On the first 40 miles or so from my home is 2-lane road. The elevation goes from about 1300 asl to 4000 asl and then back down to 2500'. Then on I-64 up to 3500' then down again to 1800' then back up to 2500' and so on. You flat landers could do a lot better than me.
Moral of the story is just SLOW DOWN. I know it's hard, I was around back when the government changed the speed limit to 55 and I did get a few speeding tickets.
It wasn't that bad driving 55 now though. It felt a little weird having a big trucks pass me but I eventually ended up catching and passing them on the next long grade.
I don't think I would like to see the mandatory 55 MPH speed limit again but I do believe it would have a big impact on fuel prices and our dependency on imported oil.

My truck normally gets 12 mpg at best getting about 250 miles per tank on 21 gallons. I headed up to New Hampshire this past weekend (mostly highway on a 220 mile ride) and my friend that I was following had a lead foot, doing 75-85 most the way, and hard on the gas. I went through over a tank (about 23 gal. total).

On the way home I went solo and kept it at around 65-70, going easy on the throttle. Made it home with over a 1/4 tank to spare (burned about 16 gal). I averaged 13.6 mpg. That's a 7 gallon difference, or a savings of almost $25 here.
