I disagree with some of these points, but the basics are certainly there. The simple solutions to bad gas mileage are clean fluids, clean filters, good plugs and a little extra tire pressure (and of course, not laying into the accelerator with a 50lb shoe off every light).

Copper vs. platinum spark plugs is a long-standing debate. I personally do not advocate copper plugs given my long standing luck with platinum and consistantly high mileage on platinum plugs (even into 60k miles of use). However, fresh plugs will certainly get better mileage than old ones so if you're not getting good mileage, replacing the plugs is certainly worth a try.

A fresh air filter is a must. Installing a CAI will bring extra noise and may hurt your fuel economy if you enjoy that sort of thing, so be sure to keep that in mind. I did not notice any difference between a clean OEM paper filter and my Legend specific K&N either... it was just easier to deal with the K&N than buying new paper elements as regularly.

PCV and fuel filter services are a must - I'm not sure when the last time I replaced my Legend's fuel filter is but it did make a difference on my BMW so I certainly advocate it.

And the biggy here that I think is often overlooked is the little extra air in the tires... again my most noticable experience here was on my BMW but +2psi on all 4 corners earned me 2mpg on that car. I've seen similar results on the Legend (though never quite a solid 2mpg).



As far as actually modifying the engine goes? My intake helped a little and I've seen suggestion that chipped ECUs make a bit of a difference but I'm not aware of anything beyond that (maybe exhaust? I don't know though...) that helps fuel economy. Perhaps I haven't been watching carefully enough

the dictator part had me laffing a bit only places in the east i know of is sunoco, bp and hess....but ive been recommended by the forum that shell is the best gas or returns the best mpg for our cars...which i can support. its better than BP even... i think mobil also was almost as equal as shell to me but theyre both up there...

so since where linked between a dictator that hates americans and middle easterners that hate americans what choice do we really have?

yeah e15 or e85 ethanol will give you less mpg but burns cleaner thats all and the cai will give you more than a 1 mpg increase it should give you about a 5 mpg jump.

I went from an auto to a six-speed in my GS. Mileage went from about 24 to 30 (got this to and from DC).

Yeah, I know that it's not a readily-available mod, but it certainly does help. Alex, was this part of the reason for your mileage jump?

Anyway, yes... clean fluids, filters, plugs, and tire inflation are the best things that can be done. Also, if your alignment (specifically, toe-in) is off, that can cause premature tire wear and in order to prematurely wear tires, you need to cause more friction, and more fuel is needed to overcome the friction!

Good luck!

what are u smoking? a CAI will not give you a 5 mpg increase. i dont think theres any 1 thing that can give an already properly running engine a 5 mpg increase.

5 hp maybe but not 5 mpg

Aside from proper maintainence of your car... a cold air intake may help slightly; consider weight reduction; improved aerodynamics might do something for you (most resistance is at the front bumper, consider air-cooled brakes like minez); drive like a grandma!

This has me skeptical from the get-go... Random e-mails from unknown senders? I'm internet-savvy, thanks.

Only $3.50? I paid $3.69 the other day... and that's at the $0.10/gallon cash discount rate.

Though these two points sound logical, I'd like to see some concrete science to back them up. Logic is often incorrect when it comes to scientific fact. (eg. two spheres of different weights fall at the same rate when released in mid-air at the same height; et. al.)

The gas tanks on automobiles are close to vacuum sealed, are they not? Not only does the cap provide a seal, but there's a valve in the filler-neck that acts as a back-up seal.

This is legitimate.



Of course the rationing was effective... IT CUTS DOWN ON OIL USE, DOY. Let's keep the politics out of this though.



Coincidentally, Shell has the cleanest and all-around best gas out there (that's both my opinion and fact supported by unbiased testing)... and Arco is notorious for having the dirtiest gas ever. Hmmmm...

Whaaaaat? That's depressing... none of those signs around here!

+5 mpg? Is that a fact?
While yes, a [true, keep in mind you need to be feeding cold air to your engine] CAI will yield a slight increase in MPG it won't be anywhere near 5 mpg.

Did not want to repost all of that tips post, but I searched it in Snoops.com they say...

It's not completely false in that one or more of the tips might actually result in some savings (however modest), but it can't fairly be classified as true either, as the practical utility of all of these tips is disputed, and the economic gains to be had from following them is highly questionable. For the full explanation...Urban Legends Reference Pages: Tips on Pumping Gas

The bottom line is that there are much easier and better ways of improving the efficiency of your car (and thus of saving you money at the pump) than the tips outlined above.

• Particularly important is proper maintenance, including engine tune-ups, wheel alignments, tire pressure checks, and filter replacement.
• Mileage can also be improved by removing from the car little-used equipment that adds weight or increases drag (e.g., sporting gear, tools, roof racks/carriers).
• Driving habits are especially important: jackrabbit stops and starts eat up extra fuel, as does driving at higher speeds.
• All in all, the simple habit of engaging in planning and combining multiple trips into one excursion will likely save the average motorist far more money (and time) than all four of the above tips combined.

Exactly like I said ^_^ but that last one is super important.

In regards to the tips post, I questioned a lot of it, but the "Time to Pump" is actually fact. There has been debate by Idaho legislature on forcing gas stations to edit pump prices between summer & Winter due to the change in Volume. So, if it is 20 degrees cooler in the morning the Volume of gas you pump would be higher.

Overall though some good tips here. I have heard, by more than one person, that exhaust systems can be fundamental in improving fuel mileage.

This is different depending on where you live... here in DC, everyone sells E15.

I overlooked this one but it's a fanstatic point: the manuals get SIGNIFICANTLY better mileage than the autos. The 6mpg difference you've suggested is just about indicative of the difference between my auto sedan and my dad's manual coupe (though, I think we're closer to 4mpg difference on our best days)

HHO Kit: Brown's Gas (from water) for fuel combustion efficiency. Any good?

Anyone have any input on this technology? I'm skeptical until I learn more....

I've heard that about the East Coast, have you ever checked a Flying J? I don't know if there is one near you, but they are a company that refines there own fuel.

Here in Idaho Shell, Texaco, Chevron, and Maverik all run non-E15 fuel. I believe Albertson's Fuel Stations and I know Stinker, both run E15 fuel.

I've seen Flying J trucks in the SW part of the state but that's 250mi from here and I have no idea where there are any stations.

I could drop in on my local Texaco and maybe see if I could find a Chevron too but those stations are few and far between in my area: primaries are Shell (which I generally run), Sunoco (my 2nd), BP (which I'll use when I can find it), Exxon (which I own stock in but refuse to run through my car) and the occasional Texaco, Hess, or Amoco.

Welcome to Flying J Travel Plazas Website! Wi-Fi Hotspot Truck Stops to find there fuel stations.

The really funny part about E-15 is if you research the refining process it takes 2 gallons or so of "Fossil Fuels" (i.e. Diesel, gas, oil, etc...) to make "1" gallon of Ethanol.

I'd hardly call it funny.

I don't remember seeing anything to that effect when reading about ethanol but it was clear that ethanol is nowhere near as efficient at yeilding useful fuel supply as fosil fuel in ideal production conditions which are rarely possible. There are advancements in development to improve this (to get it reliably beyond the 1 output for one unit input) but they are in development so we're not expected to see them for some time.

Even less exciting are the changes it's creating elsewhere throughout the agriculture industry. I find it a little painful to read about...

And for what? I hardly consider something a viable "fuel" when the addition of a 15% ethanol mix to my fuel decreased my fuel economy by more than 10%. All it does is effectively bring me back to the pump more often to purchase even more expensive fuel. Meanwhile, oil companies are reporting record profits year after year while my fuel price is at a record high and my fuel economy is a record low...

I must say though, the stock in Exxon that I own has always done quiet well...
