- both of my honda civics gas mileage dropped by 15% or so
- with this oxy gas. power seems to have dropped by at least
- 15% on the 91 civic hatchback (70 hp rating).
-
- My Dodge 3.3L went from 17 to 15 mpg, completely local.
-
-
- My Buick 3.8L with knock sensor also, I lost 2 mpg local driving.
- When I tried 89 octane, I get 1 mpg more. No significant performance
- difference. (May be my imagination, but it is a touch better.)
-
-
- On Highway from LI (Oxy. gas) to Buffalo I got 21 mpg. Buffalo I
- filled up with non-Oxy. I get 23+ on the way back.

-
- i know that a properly tuned designed-for-87-octane engine without
- knock sensor should not benefit from super unleaded.
- but as an experiment i am running super unleaded in both hondas now.
- on the 91 hatchback, there is a noticable power increase with
- the super oxy as opposed to the normal 87 octane oxy fuel.
- is this the placebo effect? has anyone out there tried this?

- I wonder, if car manuefactuers tuned the car's computer for Oxy gas,
- would MPG and performance return?
