I agree with the slower speed limit. I found that going under the speed limit has saved me gas mileage as well. I don't understand the people that feel they have to pass you doing 70 or 75 mph in a 55 mph zone. And the folks that drive the SUV's and PU trucks, I can only imagine what thier gas bill looks like...

I followed the advice of an oil service employee whom posted non-deciminated information from the tricks of the trade used at refiners about quantitative measured volume when pumped into gasoline holding tanks at refineries and service stations.  He stated that slowly pumping gasoline into your vehicle would produce more volume per fuel fill ups at the pump because faster pump filling resulted in churning of air through the nozzel which calculates volume passing through, not density of product.  I did this the other day, even though it took forever to fill up, but my tank filled past the normal amount and begin to overfill!  Luckily I anticipated something wrong and quickly shut it off, but I am happy to say, my gauge is still on full and I've driven 104 miles! He also mentioned to not wait until your tank is empty but to fill up when the

tank is at half volume so as to minimize churning.  You can use the medium setting as well when filling up, but never, never, use the fast setting as air will churn in the gasoline, creating false volume as it flows to your tank.  Also, he say to fill up in the morning while the gasoline has not expanded due to the heat.  These are little tips that are annoying to use, but produce great satisfaction when you realizie you are not throwing good hard money at the oil companies, poor devils that they are!!!

I couldn't agree more with Karen's comments. I'm amazed at the folks that pass me just to be infront of me and other's in nearly bumper to bumper traffic or drive 35  and up on neighborhood streets.

The most economical speed limit for driving was set at 55 mph during the Carter administration; it was lifted during the Clinton administration. I drive a small car and drive 55 at the annoyance of other drivers but easier on my wallet. It would be great if more people drove small cars also.  

Best advice on saving gas milliage.

1.Change air filter

2.Check tire pressure.(it will eat all your gas quick if tire pressure is low on any wheel.

3.Check oil make sure it is at level between the marks.

4.Oxygen sensor advised only if you want to take precaution.

5.Roll the windows down,(it is not that hot) insead of air conditioner.

6.Make trips all planned out in same direction for the day.(Believe me people will understand when you tell them "You dont have any gas for all that")

I don't understand why they don't reduce the speed limit across the country.  They did it back in the 70's to 55 mph.  Now, they are just ignoring.  Where we are the speed limit on the highway is 70 and everyone is driving 78 or more.  If you even try to do under 65 they will kill you on the highways.  Everyone needs to slow down.  And another thought, what happened to the truck convoys of the 70's when all of the truck drivers stopped their rigs on the major highways to protest?

Oh wow... if you drove 55 on the interstate in any metro area (let's say Atlanta for example), you would be a nuisance to other drivers and would be likely to cause a wreck. At some point, you need to think of the greater good than what your fuel economy is. It's fine to drive slower when nobody is around, but keep up with traffic/speed limit when there's traffic so you don't kill anyone! How would you feel if someone died in a wreck you caused by driving slower than traffic? How could you justify it? "I wanted to save a few pennies" doesn't cut it.

Amen Lissa....If I did 55 mph on my local highways, I would get rear-ended.  It would also be more difficult to merge or change lanes in some situations.  Think about this:  if you are doing 55 mph and you merge onto a highway where all the traffic is going 70+ mph, that is dangerous.  If a tractor-trailer comes up behind you, he can't stop on a dime.  Yes, it may be his fault if you get rear-ended but that isnt' much comfort when your car is destroyed and you have $100,000 in medical bills.

If everyone slowed down to 65 mph on the Interstate Highway System, for example,  the nation would save between 5 and 10 million gallons of gasoline and diesel fuel every day.  But everyone or almost everyone has to agree to do it.  Otherwise, if you drive considerably below the speed limit, say 55 mph in a 65 mph zone, you tend to create a dangerous situation.

The problem is most people won't slow down and drive a sensible speed. The idea of leaving a little earlier so they don't have to rush to make it on time is beyond their capacity to figure out. They are just too lazy and self centered to consider such a thing.
