2009 Year End Results - Adding Variable Amounts Of Acetone

Hello Hypermiling Fans!

Sorry it's been so long since my last post.

So, the results for 12 separate tanks of gas with varying amounts of acetone & mileage acheivements are below. I saw some really great results. First of all, to remind everyone, my test vechicle is a 2008 Ford Ranger with the inline 4 cylinder 2.3L engine with a manual transmission. Here are my results:

In conclusion, I am seeing that regardless of driving style, I am seeing a slight increase in using acetone in my fuel mixture. I find that a ratio of 3.5oz per 10 gallons of fuel is what worked best for me, so I was adding around 4.5-5 oz and getting my best mileage.

I encourage you to post your own results in the comment section of this post! Good luck fellow hypermilers!
