Finally finished

As per my last blog, I have been doing a study. It was suppose to be finished 2 weeks after my last posting but something came up and the results were trashed.

I have been doing a study on my gas mileage with the use of different brands of gasoline and their percentages of Ethanol inside them. The results speak for themselves and i PROMISE they are 100% unbiased.

History:

I travel a lot. More than normal for someone my age. I travel almost 50,000 miles a year. My record was a couple of years ago. I traveled 62,000 miles. I do everything from Paintball, Scuba, and now Hockey. Mileage racks up quick (If only credit cards had reward miles for driving.) I use all kinds of gasoline. Usually I pick a brand based on price and convenience. This summer, Shell Gasoline in my area switched to Non-Ethanol only (Smart move since they are right next to the lake.) Over the next few weeks i noticed that the mileage i was getting out of my car increased significantly. I was getting 50 - 60 more miles per tank than normal. I then decided to do a study on different brands of gasoline and with ethanol and without.

Hypothesis:

Non-Ethanol gasoline provides more mileage than Ethanol.

The Experiment:

I spent a couple of weeks deciding how i was going to do this make this as fair and accurate as possible, and here are the rules i came up with...

1. Do not count highway mileage. I do most of my driving to and from work and school.
2. Rotate a different gasoline station in the experiment. Weather changes throughout the year and I want my results to reflect conditions as close as possible to the other.
3. Do not count weeks with odd travel.
4. Full tank fills only. When the light came on I would fill the tank. Each fill was right arounf 12 gallons.

Results:

As you can see, I saw a huge difference between each brand. The non ethanol Shell gasoline provided the best result and notably made my engine run smoother. The Indian non ethanol provide decent mileage but I felt it was too cheap and made the engine run funny.

Another little side test I ran was on my boat as well.. Unfortunately the results were not good. I was unknowingly running ethanol and it killed the engine over the summer. Had it rebuilt and now it runs non only. Haven't had a single problem since.
