Not criticizing what you've done...but I think the real test is VALID on the road mpg testing as per LaPointe...not trying to translate torque/hp curves?

It was testing. If there had been gains I would have posted them. I didn't really care either way I just wanted real data about this. Now, I have a tank of gas that I need to run through that has the acetone in it.

It's completely possible that a car that would do better on higher octane would do better performance and economy wise with acetone. It's unlikely though because a car that requires premium (if it isn't driven hard) usually gets better economy on regular gasoline because of the fact that you are running the fuel on the edge of detonation all the time Your top-end performance does suffer though because it can't run full timing advance.

Who knows, maybe next time I'll come up with a more reliable way to have the throttle stops and I'll test HHO.

When I was messing with a throttle detent spring on a car...using the same throttle position used at 55 mpg cruise...I found that this position was just a few degrees off idle. The bigger the engine relative to car weight/wind resistance...the less the throttle opening?

With the 5.0 L...I think he just found the right combo of acetone and ignit timing at cruise speed throttle opening. If I had a 5.0 L around the same year I'd already be testing it....but with some MMoil top lube though.

I've never tested 1 oz per gallon.

Here's some acetone testing (not mine) done using a Civic engine tied to a generator and run with a light load...runs timed:
