The old military recips used water injection for takeoff power but
pulled it off as soon as airborne so I doubt it added anything to fuel
efficiency. More likely it just allowed for more boost - some of
those suckers had blowers as big as the engine - without blowing the
heads off. AIR, it was only used for specific weights and density
altitude situations so there must have been a reason not to use it
every time. Stands to reason - anything that will take the carbon off
can't be gentle on the rest of the parts. Ever look at anything
exposed to superheated steam?

There's nothing wrong with the colourtune - it simply lets you find out that
the design of your intake manifold is crap ; the cylinders at the end burn a
bit lean and the ones in the middle burn a bit rich (on a single carb
engine).
Can be quite useful for setting up multi-carb engines though.

Early commercial jets used water injection for take off, it was used in hot
climates.

Mike:
My stock 78 Chevy 4x4 3/4 ton retired farm truck gets @ 10 mpg, I don't
consider that too bad for a
old clunker with full time 4WD. it's been a superbly reliable vehicle.
My wife's 93 Olds Cutlass Cierra gets @ 36 mpg. poorly designed front brake
calipers.
Our 73 Tioga Motorhome gets about 10 mpg. not bad for the amount of air it
pushes.
The stock XJ only gets @ 20 mpg., and it's smaller than the Olds.

I have had a Colourtune for 30 years, use it often, bought it new on
holidays in UK for $15.00cdn.
Great for outboards and motorcycles, 'Never seen anybody else use one.

Bill:
"Real Gas", remember it well, we had 7 gas tractors on the farm, I haven't
smelt that for years, yup
better mileage than the swampgas/propanized/ oxygenized stuff that seems to
be everywhere now and
it starts rotting in a months time if you don't add fuel pickler to it.
