Gas Saving Myths

Six Actions That Won't Help You Save on Gas

There's no question that Americans have been obsessed with gas lately, and with the majority of you spending between $100 and $200 a month (and a quarter of you spending more than $200) it's no wonder that gas is on the tip of everyone's tongues. We've explored various gas saving methods that will supposedly help save some money at the pump, but with everyone claiming they have the key to spending less on gas CNN Money felt like it was time to clear up some common myths. Do you believe these are misconceptions, or do you think any of these actually do work?

  1. Fill your tank in the morning: Consumer Reports says the temperature of gasoline as it comes out of the nozzle varies little during the course of the day, so getting up early to pump gas will yield negligible results.
  2. Change your air filter: Maintaining your car is important, but a clean air filter isn't going to save you any gas.

There are four more myths so just


  1. Use premium fuel: You're not getting better fuel economy with premium fuel, and are really just paying more money for nothing.
  2. Pump up your tires: It's true that under-inflated tires reduce fuel economy, but over-inflation reduces friction and adds the risk of crashing your car.
  3. To A/C or not A/C: In around-town driving, using the A/C will drop fuel economy by about a mile a gallon. The best choice - if temperature and humidity allow - is to keep the windows rolled up and to turn the A/C compressor off.
  4. Bolt-ons and pour-ins: If there really was an additive that made gas burn up more slowly, it wouldn't be sold over the Internet one bottle at a time.

Ultimately, your driving habits and what kind of car you drive are the two elements that could surely help you save on gas.

I've never heard or don't believe any of these...I'd definitely say they're all myths.

I spend maybe $100 at most a month. It's all about driving a fuel efficient car and living as closely to your workplace as possible. A tank of gas can last me about 2-3 weeks.

I buy gas when I need it and drive much slower than I used to, but I choose not to keep up with what I spend. It would only depress me, as most of these comments have.

I just realized people who have to commute get a pay cut with every cent the gas raises. That sucks.

Gas in LA is over $4 for all of the "nice" gas stations. Cheapy ARCO for me! One tank lasts about 4.5 days for me. I pay soooo much in gas for commuting!

Faerymagick15, gas in the Bay Area is $3.89 if you go to the cheapy gas stations like Arco. Otherwise, it runs at least around $4.00 for 87 Unleaded. Count your blessings. ;)

we have a minivan which costs about $65 a tank...I fill up once a week usually in the morning, don't know if that matters. I use regular and I do notice a difference in my mileage after the air filter has been changed and the tires checked and inflated if needed. My husband has a 2008 Mustang GT which costs $55 to fill. He ONLY drives it to work and maybe one other time per week. It is very hilly around here, which doesn't help. I don't know anybody in my area who only spends $100-$200 a month on gas! Most of us are spending upwards of $400-$600 a month easy. Most that liver here commute at least 15-25 miles to work. With a family it is hard to drive a compact car that gets good mileage and still have room for everyone and everything.

I live about 18 miles from takes about $81 to fill up my tank. I usually fill up once a week. My husband drives a truck and it takes about $72 to fill up his truck once a week. So yeah with gas prices right now around my area ($3.49 for regular) it's a huge expense.

Good tips! I remember seeing the rumors about things like filling up in the morning and then seeing that they were not true; it's nice to see that a very well known source is proving them to be myths as well! Sometimes you don't know who to trust.

Luv2gossip, I feel for you! That's so much on gas!

Luv2gossip. I was one of those between 100-200. I drive a mazda protege5. I get 28 mpg and drive about 30 miles a day to work. On the weekend I try to walk to as many places as possible. So I fill up about 3 times a month at $45 a tank (currently). What I have found about hatchbacks is that they have the same interior space as smaller SUV, just without the "suv". zoom zoom!

Holy crap $600 a month. I think I would get a scooter if I was paying that much in gas, luv2gossip.

I'm doing the same as SkinnyMarie - putting my car in neutral whenever I can and just "cruising". Where I live it is mostly flat with little traffic, so I am able to cruise in neutral quite often. I have added an average of 4 miles per gallon doing this.

Where do the people that only spend $100-$200 a month live? I live in TX and we spend an avergae of $600 on gas!! I need to trade in my Yukon!

Interesting, I have to admit - I only heard of # 5 before this post.

I have come up with a crazy idea. Its pretty damn hilly here in pittsburgh, so on a road that I would usually keep my car in gear (Drive a stick) I have been just putting my car in neutral and roll as much as possible without losing speed. Just seeing what happens with this tank. I don't think its working any better, nor do I suggest other people try it. Honestly though my boss is thinking of moving our company downtown, so that right there would eliminate my gas consumption since I live downtown.

I've really reduced my speed. This is the one I hear works. Everyone else continues to drive 5 to 10 miles over the speed limit but I'm not sure why?

I've read all these in silly email forwards. Good to know they're myths because I ignored it!
