hey all, im a newbie to the forum, and so far just about everyone has been really cool and helpful in helping me get ideas for my 03 ST i got last month.

i live in CA where gas prices are crazy, so ive been getting into this hypermiling craze and it really works. i also commute in my ST during the week driving about 360+ miles per week. ive been able to squeeze so many extra miles out of my gas during my commutes by following a few easy tips. i have been able to squeeze about 550 miles out of one full tank of gas in my 03 ST XLT 4X2, and that was without letting it run bone dry. so if you want to save money on gas, or want to help the environment, or both, here are some tips that i picked up that work best for me. some of these you may have already heard, but if you do them all-together you can really save some dollars on gas, which means more money to put into your truck! i also left some links below to hypermiling.

1. DRIVE SLOWER ON THE FREEWAY - of course you want to open it up when you are cruising around on the weekends or when you are out wheeling, but when you are on your M-F commute, it really saves money to drive 60 mph or below. i read a figure that said for every 5 MPH you drive over 60 mph, you are decreasing your mileage efficiency by 1 MPG and for every 5 MPH you drive under 60, you increase by 1MPG. if you leave for work a few minutes early and drive 55, you will see the biggest difference in your gas mileage. driving like a grandma really works in saving you money. i try to keep my tach needle from jumping around, and i try not to let it get any higher than 2000 RPM's when im on the freeway. no jackrabbit starts off the stoplights, and no peeling out.

2. USE CRUISE CONTROL WHENEVER POSSIBLE - this will keep your RPM's from jumping up and down while you are at freeway speeds. if you have a +/- feature on your cruise control, use this to accelarate or deccelerate when you are at freeway speeds whenever you can and the when the road is open.

3. DRAFTING - when you are on the freeway, find a big rig and get behind it. the big rig will cut through the wind for you, causing your engine to not work as hard trying to cut through the air and wind. i do this whenever possible, i try not to follow too close so i dont piss off the truck drivers. this is probably not a good idea if you have custom paint, or baby your ride as the trucks can kick up rocks sometimes, but if your truck is a daily beater, go for it, it makes a huge difference. I've even seen truck drivers taking turns drafting each other to save gas.

4. LIGHTEN YOUR LOAD - take out/off any unneccesary weight. stuff in the back seat and bed, roof racks that aren't being used, camper tops, tools that arent being used, anything you dont need on a daily basis will help. you can increase your MPG by 1-2 MPG's for every 150 lbs you take out. one way that i figured out how to lighten up my load was to only fill my tank up half way at a time during my commuting days. i have to pull up to the station more, but by only filling up half way, im cutting that much weight off my load when im commuting.

5. KEEP UP YOUR MAINTAINENCE - keeping your sparkplugs up to date, and all your filters clean really helps in increasing your mileage efficiency. the most important aspect to this is your tire pressure. if your tire pressure is low, that will greatly affect how many miles you can squeeze out of your gas. ive heard of people overinflating them to get even better mileage, but ive been doing fine with keeping them where they should be.

6. SOME MODS UNDERNEATH MAY HELP - some of the mods you may already have might already be helping you save on gas. MAF or CAI intakes and aftermarket exhaust systems help increase gas mileage as long as your foot stays light on the pedal. i noticed a signifigant difference with my KN intake.

7. GET AN APP FOR YOUR PHONE - getting an app for your phone to help you keep track of your fillups can show you how much gas you've been saving or wasting. some even have graphs and provide tips on how to save money on gas. the best part is that you can find any number of these apps for free.

8. GET GAS AT THE COLDEST TIME OF THE DAY/NIGHT - gas is measured in volume at the station, but not mass. because of condensation, gas is at its most massive during the coldest part of the day, but still able to fill the same volume. get it? so filling a 1 gallon jug of gas in the hot afternoon has less mass than filling a one gallon jug of gas during the middle of the night or early morning meaning you just got more gas. it's not much by the gallon, but by the couple tanks full, it is.

9. MINIMIZE HITTING STOP LIGHTS - when im city driving, i figured the places i frequent the most and figured routes that have the least amount of stoplights for each destination. driving a mile or two more distance-wise can save you twice that extra mile or two if you dont hit any stoplights. idling engines are engines burning gas but not getting any mileage.

OTHER TIPS - roll the windows down during city driving if its hot, and roll them up and turn the ac on at a minimum once you hit the freeway. coasting whenever you can. i coast as much as i can and i always take advantage of downhill driving. time stoplights by slowing down to a crawl until it turns green so you never have to stop completely.



my girlfriend started hypermiling too, and her mini cooper S gets around 36 MPG freeway. she went over 535 miles on one fill up. thats a 13 gallon tank meaning she was able to squeeze out about 41 MPG! my personal best in my 03 ST was 550 miles on one tank, meaning that on a 20 gallon tank, i was pushing 27.5 MPG, and that was without me even getting down to the fumes. imagine how much money i'd be saving if gas prices actually went down.

i hope some of these tips help you guys save money on gas, putting it all together has really helped me save big money on gas, and since everyone on this forum has been so helpful to me, i thought i'd return the favor. it sucks at first driving slower and taking more time to get places, but you get used to it and realize you are only getting there a few minutes earlier when you are flooring it. please post any ideas or tips for saving money on gas if you have any that i didnt mention. and also share any experiences or thoughts you have if you try hypermiling. thanks again to everyone who has been so friendly and helpful since i joined the forum.

Wow!

Careful tailgating those 18-wheelers!
 






I absolutely hate when people in a four wheeler, sorry (car or truck) would tailgate me or try and draft me.

I've seen too many accidents OTR over the years where four wheelers have gone under the back of a trailer, none of which survived just to try and save gas or just because they think they're not that close to a big truck. I've also seen where a big truck will get a blow out and the tread of the tire has gone through the windshield of the following car causing it to veer over into oncoming traffic killing a family in that car as well.

If you can't see the driver in the big trucks mirror than you're way to close, even than it's not really safe. I usually drive over to the rumble strips and kick up some dirt just to get them to back off or go around and surely enough it works.

Stay safe out on the roads and remember to keep a safe distance from a big truck, anything can happen in a split second and you won't have enough time or room to get out of trouble.
 






yeah, i didnt make it enough of a point in my original post to not ride the tail of a big rig, but to just drive behind it (at a safe distance). i clarified on another post of the same thread. i mentioned in the original post to not follow too close, i shoulve said not to ride the tail of these big rigs. i myself will try to find a big rig, but i dont ride their tails, i just ride behind them.
 






No problem. Just getting a safety tip out there.
 












Yeah, but you can take advantage of the Earnhardt slingshot to make the pass... :D
 












His notes about speed and cruise control are dead on! I drive out to Penn state a few times a month, 160 miles each way all highway, and as soon as I am over 70, the gas mileage drops alot.
 






About #8, seeing as the gasoline is stored underground, i cant see there being that much of a temperature difference in the course of a day.
 


















If you're worried about mileage, shouldn't you buy a prius?

I drive my car most of the time, and the truck when needed.
 






No, just because you drive a larger vehicle doesn't mean you have to not worry about fuel mileage. The more money you save doing the daily driving means you have more money to spend on hobbies.

Now, if you don't use the vehicle for fun or need something that big, then maybe, just maybe its worth buying something smaller, But if the vehicle is paid for it will take too many years to recoup the cost of the new vehicle (read prius).

It also depends on miles driven. I did retired the X as a DD a few years ago when Gas got to $3/gallon, but I'm also driving 70 miles a day, just commuting to/from work. I picked up another vehicle for $4000 and paid for it in just over a year in fuel savings. Of course, you still have to factor in repairs/maint, and vehicle insurance. Heck, if you live in the city you have to worry about parking too. Sometimes, replacing or adding the vehicle is just the wrong answer.

i cant afford a prius and an explorer, and my gf's mini, and even if i could it wouldnt be cost effective to buy a brand new prius to save on gas. but it makes a little sense to me to make a little effort (most of the effort being free of cost) and take a little extra time and save money on gas. i live in california, you wont find a better place to live if you love the outdoors (3 hours or less away in every direction from snow, mountains, beaches, deserts, forests, fishing, camping) but gas costs major bread. the more i can save on gas, the more fun stuff i can do. i like to have toys, but im not rich so every bit counts.
 






I've squeezed 28mpg on one tank out of mine, just by keeping the speed down to around 55mph. We were touring Colorado and just kept it around 55 or so on some of the winding roads.

Now I'm trying to get my equally miserable (mpg wise) '77 Chevelle to match the Explorer, so far in town they are about 2mpg different, (13 vs 15). I've not had the car on the highway for any length of time to do any good and get an accurate consumption.
 






28 mpg is pretty damn good. the best ive been able to do in my 03 ST is about 27.5 MPG. i also hit the freeway around 55-60 and i try to keep my RPMs at 2000 or less. i have a pretty long work commute and with all the weekend driving i do, i was spending about 420 bucks a month on gas. ive been trying to meet my goal of getting 20% efficiency increase on my mileage, that equals to about 80 bucks a month on savings which means more money that i have to go into my toys!
 






Great post LONO.

I just recently watched this episode of Xtreme 4x4 on saving gas mileage and actually increasing it with your daily commuter/weekend off roader. Some of them LONO hit on, like the get out all excesses weight, but has anyone tried any of these other tips?

If so, has people had any luck with those mods?

the only mods ive done engine wise was the KN MAF intake, i have a magnaflow exhaust which came with my ST when i bought it. i have heard of electric fans making a world of difference in MPG, but i dont know how long it would take in gas savings before i would recoup my money back, and there's tons of other stuff i want to get for my rig before that. maybe if i cash out at the casino i might get one, if i do, ill be sure to post my results.
 






If you're worried about mileage, shouldn't you buy a prius?

I drive my car most of the time, and the truck when needed.

I bought a '95 Saturn SL2 for $1500. I've parked my Explorer to be used only on weekends, to haul my mtn bike and to tow my popup camper. The Saturn handles the pavement pounding back and forth to work.

I'm about to fill up the Saturn for the 3rd time, giving me 2 tanks worth of mpg data. The first tank yielded me 33.6 mpgs. A tank of gas in the Saturn takes me the same distance as a tank in the Explorer, only difference is that the Saturn uses half as much gas. The last tank saved me $35. While at that rate, it'll take me 42 tanks to break even, I also have the added advantage of having 2 vehicles at my disposal.

Is the cruise control really that useful? On the highway I suppose I can see that (but I manage to keep a steady rpm with my foot anyway), but on normal roads from my observations it seems even worse. Whenever I hit a hill it really gets up there quickly (jumps to about 3k) just to keep me at the same speed. Does some pretty good engine braking downhill though.

And as for the +/-... when I've used it, I've noticed that it again really kicks the rpm to get to that speed. I can accelerate a lot smoother than my CC lets me.
