Improving Gas Mileage 2

Keep Your Car In Shape
 -Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent. 
-Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by up to 40%

Keep Tires Properly Inflated
While also being safer to drive, maintaining proper inflation levels in tires effect your gas mileage by 2-5%! It will also help make your tires last longer saving money there as well.

Use the Recommended Grade of Motor Oil
Ever change or top off your own oil? Well make sure you check what kind its supposed to take. 10W-30, 5W-30 ,5W-20 are obviously labeeled differently so choose the correct one for your vehicle. Another tip is to look out for Energy Conserving oils that include friction reducing aditives. Were looking at a 1-3% mpg increase here folks.

Replacing a Clogged Air Filter on Modern Cars Improves Performance but Not MPG
I've always thought having a dirty and old air filter cold effect my mpg. But I guess I was wrong and the myth has been dethroned.  While replacing filters does not improve fuel economy  it can improve acceleration time by around 6 to 11 percent. Its also important to realize that this is for "newer" cards made in the 1980's and forward. Tests do show that older cars suffer a 2-16% reduced mpg reduction with old filters. Yikes!

Improving Gas mileage

My next few posts are going to be about saving money by improving your gas mileage. The idea came to me when I was driving back down to school yesterday. With the trip being about 6 hours and approximately 400 miles me and my buddy had a lot of time to talk about stuff. Our packed to the brim Honda Accords gas mileage was one of them. Anyway the posts are going to cover the four main ideas presented by . These include driving more efficiently, keeping your car in shape, planning trips effectively, and choosing a more efficient vehicle. For the most part I like there ideas, but I will be adding a few things of my own that I feel they left out or have exceptions.In the mean time while I work on these id like you to check out a few really cool "fuel efficient" cars these posts won't be about.


This free magnetic engine running this car is just amazing. It seemed well enough to be used in everyday commuter cars and it only needs a battery to start the engine. Combine this with a Prius and throw more money at it and we have a great car here people. Sadly though as most people know this will probably never get off the ground. Most of these competing engines always seem to be bought by bigger car companies and then abandoned.


Here is another engine. Because it has shafts on both sides I'm told it is actually much more powerful then most magnetic engines. However It is also a lot larger and most surprisingly it is not perfectly rounded in shape. This means its losing a lot of efficiency by not maximizing it centripetal motion.

Overall I think I would pick the Audi..Just because it's a bit more realistic. Cheaper, better mileage, and still a beast on the street and the track...Sexy and Stunning. What do you think?
