I was getting about 13.7 in the city before I tried vapor injection. I took a road trip with my friends this weekend to Lafayette, which is about an hour away from Baton Rouge. I drove right around 75+ and had to floor it a few times to catch up with our leader who was terrible.
I averaged right around 17.1 which doesn't sound too great but it seems like an improvement because there are a few factors to consider.
1. I drove faster than most highway ratings are posted at. If I had gone about 55-60 for the drive, I may have averaged about 18 or 18.5.
2. I also had to floor it a few times and I know that takes a decent amount off of the average mpg.
I'm thinking it's working but before I start adding stuff to the water, I'm going to see how it does on distilled water alone in the city.
I'm thinking of adding acetone or methanol, or possibly both to the water to see how it works out. Acetone has very flammable vapors and the methanol will assist in vaporizing the water, so maybe that will give me a little extra push.
I'll post results from my city mpg on the next fillup.
