Testing (DIY)
Q How do you know it's working?
A Do some tests.
Possible DIY (Do It Yourself) tests include:
1) Idle speed
The idle speed will pick up in an non-ECU (Electronic Control Unit) engine
i.e. Those having a carburettor
Cars with an ECU will not show any increase even though a decrease in
friction has occurred.
2) Wear
a)
Start using a
magnetic sump plug:
Take a picture of how much metal collects on a magnetic sump plug
and then check how much collects after treating with Xcelplus.
Weigh the magnetic sump
plug before and after treatment. If the weight of the plug decreases the
amount of wear has decreased: You'll need a balance capable of measuring
~1 milligram
(1/1000 gram). You will also have to remove excess oil and grime
from the plug: A wash in petrol will remove excess oil. It is usually
very easy to see the difference with the naked eye.
b) Use a oil patch tester (refer Fluid Rx Diagnostics) or put a drop of oil on a piece of filter paper and see how dirty it is before
and after. Filter paper makes it easier to accurately determine how dirty oil
is. The difference in colour is sometimes quite dramatic (black v's clear) and
can be easily picked without the aid of a filter paper.
c) Send the oil to a lab for analysis when you change it (do a before &
after test).
N.B. Iron should be <95
ppm (Parts Per Million). Normal wear is often ~25 ppm (25 mg/L). After
treatment the wear can drop to <4 ppm (4 mg/L).
If wear has dropped, due to reduced friction, so
has the temperature of your engine. Oil lasts longer (works better) when
it is carrying less wear particles and running at lower temperatures.
3) Fuel Economy
Keep a log book, reset your trip meter each trip and fill the tank to the
top each time you fill the car (to ensure consistency). The longer you keep your
log book before adding the Xcelplus the more accurate your measurements will be.
Use the same type of fuel each time (E10 (ethanol), octane ratings 91, 93,
96, 98, etc...) preferably bought at the same service station and using the same
pump. Fuel can vary even if you use the same chain to refill e.g. BP or Shell.
E10 (10% ethanol) in particular can have a marked effect on mileage (~10%
less than petrol without ethanol). Do not use E10 if your car is not designed to
use it: can cause vapour lock or corrosion
Gas (LPG) is normally a mix of butane and pentane but that mix can vary
significantly e.g. 100% Pentane (which is not very common) will give
significantly better mileage than a mixture of
both gases.
4) Compression
Test across all cylinders and write the readings in your log book before
treatment.
Repeat compression test after treatment.
5) Noise
Make a note of engine noise noting the location and type of sound. Use a
sound meter if possible. A stethoscope will also help you pick up changes... but
is not as accurate.
Machinery often shows the biggest measurable reduction in
noise but some engines
become so quiet it's hard to hear them.
6) Vibration
Vibration meters are used on equipment (like compressors) to indicate when
they are about to fail. These meters can be used to quantify any reduction in
vibration. The improvement is often very obvious even without a meter.
7) Starting
Note how long it takes to start the vehicle before and after (number of
turns)... or how hard it is to turn the engine over.
Cold starting is significantly enhanced: Starting on cold days drains the
battery more than on warm days
Measuring amperage or starting voltage is often a
simple way to establish easier starting i.e. lower voltage or lower amperage
means easier starting.
8) Exhaust emissions
Note the colour of your spark plugs before & after. The
lighter the plug the cleaner the burn.
Note the amount of carbon collecting at the end of your exhaust pipe. The
less carbon the cleaner the engine.
Note the amount of smoke your vehicle blows and the colour (blue or black)
before & after.
Your local mechanic probably has an emissions tester which can measure levels of:
02 (oxygen),
CO2 (carbon dioxide), CO (carbon monoxide), NOx (Oxides of Nitrogen) and total level of
HC (unburned
hydrocarbons).
N.B. If fuel efficiency is improved then emissions have decreased
9) Power
Engines become more
responsive and have more power after treatment
Does the engine pull heavy loads more easily?
Does it go up steep inclines faster?
Does it make less noise? N.B. Quieter means more power!
N.B. A dynamometer is the most accurate way to test.
10) Responsiveness
Engines become a lot more responsive after treatment.
This means the power comes on earlier/sooner.
Raceboats and cars often notice their lap/race times improve.
N.B. A dynamometer will objectively measure this improvement.
11) Reliability
If you keep a log book you should log any breakdowns before and after
Xcelplus. The number of breakdowns (engine related) should roughly parallel any
reduction in wear i.e. A 50 % reduction in wear should result in roughly half as
many breakdowns.
Xcelplus will also reduce the number of items that
need to be replaced or rebuilt e.g. A 50 % reduction in wear will
roughly double the life of an engine. It is often easiest to notice the
improved lifespan on faster wearing parts like cam chains, rings or
bearings.
12) Electrical
Many electrical parts last longer because they are less stressed e.g. Brushes
in starter motors last much longer as it takes less power to turn an engine over and
less turns to start.
Batteries will last longer because it takes less power to turn over an engine.
Spark plugs can have a longer working life if they are burning cleaner.
Keep a log book and compare your vehicle to similar vehicles to see if the
incidence of problems is reduced.
10) Temperature
A decrease in temperature is easiest to spot in older cars which are starting to
overheat:
The temperature gauge will drop from top 1/3 back down to normal (typically
bottom 1/3). This typically happens quite rapidly (within ~60 minutes).
N.B. Testing temperature is easiest on air cooled engines (or
engines without a thermostat). On a water cooled engine the thermostat will work
to keep the temperature constant. Thus car temperature gauges will usually not
tell you if the temperature/friction has dropped.
Air cooled engines have the greatest potential for a reduction in temperature
because their oil temperature (often 130 - 180˚C) normally runs much
hotter than the oil temperature of water cooled engines (~80 - 100˚C).
Look:
Some engines glow because they run so hot. If they stop glowing then the
temperature has decreased e.g. headers on rotaries
Touch:
Some engines are too hot to touch. If they can be touched after treatment
then the temperature has dropped significantly e.g. motorcycle crankcases
Smell:
The engine will smell less if it is running cooler: It's probably the oil you
are smelling
Listen:
If the noise has dropped then so has the temperature
General comments
This list is there only
as a starting point. The type of measurements you undertake can reflect the kinds of problems
you encounter and the type of engine or machine you are treating.
Make sure you give the treatment enough time to work before
testing.
N.B. The ECU (Electronic Control Module) keeps the
engine parameters in the normal range. The ECU does not like rapid
changes in parameters. The ECU may need to be reset to allow it to
accept an improvement in efficiency. Disconnecting the battery to clear
the ECU can hasten this process.
