Like I said, you can do mods that will result in an MPG or two. But you are losing more money than you are saving.



don't forget those with larger tires are not getting correct miles on their odometer to properly calculate mpg

adding free flowing intake and exhaust will cause the trucks computer to adjust to keep the air fuel mixture correct.....more fuel being used is worse mpg....if it adds more power, then the power moving the truck easier could help with the mpg...however everything I've seen in my long history of modding cars is

you're not going to get much faster unless you turbo/supercharge...stroke/port/polish

I've always said..want a fast car, buy a fast car...want better mpg, buy a better mpg car....

Only vehicle I've seen get a better "bang for the buck" performance which are minimal are lightweight pullys, disconnecting AC, electric fan

however if you can't do these mods yourself you spend more money than it's really worth.

good luck on finding magic bullets!

change the ".0" to "cyl"


jk....I drive slow, shift low (2.5k-3k rpms) and get to pass by more gas stations...accel fast, shift 3.5k-4.5k and gonna be getting in the teens as far as mpg's go.

blanket statements can be a bit misleading...the cost/benefit ratio kinda depends on how much you drive...

I drive close to 20,000 miles a year, so saving 1 MPG can save me over $150.00 each year...so maybe that K&N filter or tonneau cover does make some economic sense

I get a pretty consistent 19 mpg on my truck. I have a canopy, larger tires, and I hit the freeway and set the cruise at the speed limit. The biggest thing is that I don't drive like a leadfoot anymore. I see anywhere from 16-20 mpg with these tires on the truck. With the last set, a more road based tire of Wrangler RT/S's I saw a couple tanks at 23 mpg. Tires can make a huge difference along with driving style. I have added a K&N and I use nothing but synthetic motor oil in my truck. I also do all the maintenance when it should be done. There are a lot of gimmick items out there that claim to add mpg, but they really aren't worth a damn. I know from building several cars that mpg can be majorly affected by the way you drive, and how the car is maintained. Also like was mentioned before is weight. Do you really need a 50 lb (guessing at weight) truck box with another 100 pounds of crap in it that doesn't get used? I do carry some essentials, stuff mostly if I break down since I drive 90 mieles round trip every day from work, but for the most part, if it doesn't need to be there its out of the truck. The other thing is plan your route, if you can hit freeway or a highway to get to where you are going instead of 3 miles of stop and go it can help your mileage, remember that most cars (this is a generalized statement and in no ways reflects every vehicle, the way a vehicle is setup, 3.73 gears for instance versus running 4.11 gears can make a difference) run best at around 55 mph and obtain their best mileage, so doing a lot of start and stop you aren't getting that. You might also look at a block heater, your engine is designed to run at a certain operating temp, and especially in winter depending where you are (Montana) your vehicle will stay in what is called open loop operation until it reaches the correct operating temps. A lot of newer, as in the past couple years will go to closed loop and run more efficiently even cold. Open loop is where your ECM ignores your catalytic converter and runs the engine rich on initial startup till the engine gets to a certain temp. I know in Montana I wasted a lot of fuel just letting my truck idle to warm up because if I didn't the transmission howled like a monkey, so I put a pan heater on it. Reducing idle time also during your day can raise your mileage. Don't let your truck sit and warm up, be a man (or woman) put on a coat, and start driving down the road, it allows your vehicle to warm up faster, and reduces idle time. Remote starts are for (rhymes with wussies).

A couple things come to mind here, Run as skinny a tire as possible. This would be comparable to a road bicycle with tiny tires as opposed to a mountain bike with big tires. The road bike will always be faster.

Change your differential fluid to Full-synthetic and buy the pure teflon from ford and put one bottle in the diffs (4wd).

Run premium fuel. The average difference per fill up is only about $2-$4 more than 87. When you get another 20-40 miles per tank than the premium paid for itself.

Run full synthetic for oil in the motor.

Run a hotter plug or a platinum/iridium plug.

Change the air filter to a free flow filter.

If you have an automatic, get a computer from a manual, the pre-programed fuel curves are different from auto to manual.

I'm a diesel major and a car nut, I took a class in fuels and lubes, running synthetics is a good thing. Running premium fuel if you drive a car is not going to gain you mileage! Don't spend 20 cents more a gallon. Running 92 octane or whatever the highest you can get in the state you are in won't improve your mileage, it will only cost you more money. You aren't saving any, an octane rating is the resistance the fuel has to explosion, running premium is for turbo or supercharged cars, or high compression, you have neither in a common Ranger.

As for changing your ECU to a manual tranny ECU vs an automatic, that doesn't make sense. You then either have a transmission that doesn't work, since they are electronically controlled, or have to run a stand alone ECU just for the tranny, which costs a LOT of money.


As for the Honda Civic mod...if you're a douche waffle you do this HAHAHA

Good advise Richard. I live a few miles out of town in a trailer park. One good thing when gas prices peaked the 2nd time (1st post Katrina..2nd June/July 2008 before the recession hit big time) was it caused me to rethink shopping in general. Though I'd rather not..I started shopping right after work..to combine the shopping with my home commute. As you say without actually increasing the mileage you get many can save a noticeable amount by not just losing the 'Lead Foot' but by planning driving routes in a better way. Besides saving on gas this can also increase your leisure time at home which many can use nowadays.

Same complaint people had in jeeps (former jeeper) sold that thing when I had 4:10 gears..low range transfer case and meaty 33's on steel rims....yeah my sub 10 mpg sucked.....ended up selling it lol

sometimes ya just have to do what you have to do....I say save money..don't buy mods that don't work..and you can do the civic mod for around 500-700 bucks :-)

Well I can vouch for this with premium fuel in a real world situation. In my '97 when I put my headers on the stock manifolds were black and suity. After I installed the headers and the intake I started runing premium fuel. About a year later the cheap paper gaskets that I used from headman had failed. I removed the headers and use stock manifold gaskets. To my amazment the headers were white, Clean from running premium fuel.

That means that all the fuel was being burnt giving more bang for your buck if you will.

The suit from the manifolds was a sign of unburnt fuel in the exhaust.

If you have a 20 gallon tank and premium is .20 more than regular it will cost only $4 more per fill up. (if empty)

In my ranger i get 300 a tank on 87. When I run 93 I get 350. At 15 miles a gal on 87 I would have to buy another 3.4 gal. to get the same miles.

If gas is $3/gal, then to get the same miles it would cost an extra $10.

Had I bought the 93 I would have only spent an extra $4 at the fill up. Saving you $6 each fill up. If you fill up once a week you will have saved $312 a year. And your truck will be running better/cleaner.

Also, around here we have good gas (shell,BP,Marathon) and cheap gas (wesco,Speedway,wal-mart) and that makes a HUGE difference.

I had ran the wesco gas and was getting 250 miles a tank, switch to shell and got 350. And that is NO BS.

I'm in California and my milage has tanked the past month. My driving style is fairly tame and I run regular from 76. That has been good gas in the past but right now it doesn't matter. I think the formulation has changed for the winter and it no longer has the energy of the summer mix.

It does change. It has to do with evaporative emissions, you have less evaporation in the fall and winter when it is cold. But in colder climates IE Montana, you need something that will burn quicker more like in summertime, so it has more aerosal characteristics but is more potent. If that makes sense. While summer they switch to a less evaporative fuel that takes more to burn, which the extra heat of summer will take care of.

Um, it doesn't matter what you run for fuel, you will get soot, every exhaust gets soot, that is part of the emissions, and crap the government is trying to reduce. Running headers will change the way an engine runs and pushes exhaust gases out. You also didn't run your headers as long as the stock manifolds and exhaust manifolds are not as smooth as headers, so they will collect more crap. But truth be told, yes you apparently saw a difference. I can't explain that, but from everything I have researched and experienced myself, you in no way need to buy premium. Maybe I'll try this myself and see what it results in. But I find it a little hard to believe this. Also by switching to higher octane fuel at the same time as you switched the headers really didn't give you the chance to experience regular fuel mpg on that set up. Which will scew your results.
