AAA’s recent statements to the Public about using Premium Fuel
in cars that do not require the higher octane fuels
do not tell the whole story
~ while ~
my 40 plus years of Automotive Service and Testing proves otherwise
~
Gasoline is: (HC) = Hydrogen and Carbon
Most ~ Regular ~ Fuels today have Alcohol added ~ blended ~ into the fuel
called Ethanol
starting from about 10% and up to what is called E-85
and after about six weeks the Gas and the Alcohol separate and do not mix back together
while putting Ethanol Fuels in older Vehicles not designed for Alcohol in the fuel system
does permanent damage to many components of the Vehicle
it damages all the rubber components in the fuel system
from the Sending Unit and Float in the Fuel Tank
and all the Rubber hoses in the Fuel system
while damaging the Fuel Pump
and then Damaging the Carburetor
while changing the ability of the float in the carburetor from functioning properly
do to a change in Buoyancy caused by the Alcohol
causing Flooding of the Engine in many cases
and in other cases the Ethanol can cause pre-detonation in the combustion chamber
called Pinging
that can not always be heard by the Human ear causing permanent Damage to the Engine
as there is a more inconsistent erratic Explosion
in the combustion chamber with Ethanol Fuel
while Vapor-lock is more common with Ethanol Fuel
as well as harder starts on hot engines
from fuel that is already heated and expanded before interring the combustion chamber
and
when I was pumping gas at 16 years of age in 1970
after school my freshman year of high school
Regular Fuels in the 60’s and 70’s where about 95 Octane
and Premium Fuels as high as 110 Octane
back when Compression Ratios were much higher
and Ignition timing was advancing much further
while Octane today is Calculated differently than back then
while from my testing
Non – Alcohol Premium Fuels
do not do this damage or harm
while in newer Cars designed to run on Regular Fuels
do not run properly when the the Gas and Alcohol separate
while the Ethanol Fuels produce higher levels of CO2 by as much as 15% to 20%
from 14% CO2 out the tail pipe to as much as 17% out the tail pipe
than Non- Alcohol Fuels
while my 40 plus years of testing shows
Vehicles designed to run on regular Fuels
that have switched to Premium Fuel
do have an increase in Performance and Fuel Economy
lowering the cost of Fuel in some cases
while the Premium Fuels have added Detergents in them
keeping Fuel Injectors in better working condition
reducing poor Performance and the cost of Maintenance
while producing less
Carbon based Oxygen = CO2 = Carbon dioxide
as the Alcohol in Ethanol
is made from Corn and contains the highest level of Carbon of all the Foods we eat
while thousands of children are staving to death on this carbon based earth everyday
as the U.S. Tax Payers are subsidizing turning food into fuel
that provides zero benefits to this world
while damaging any and all outdoor power equipment
and if you are using Regular Fuel in your new Turbo Charged Vehicle
this could damage the engine and void the Warranty
and
that’s my two cents worth
as I refuse to put Ethanol in any of my Vehicles
after dealing with these issues Professionally every day as a Tune-up Technician
and Dialing In ~ tuning ~ Race Cars for the past 40 plus years
while my Father years ago was a Head Operator for a very large Oil Refinery
and the only fuel Dad put in his Vehicles was Premium

and how to de-tune your pre computer vintage Vehicles
as this would apply pre 1979 Cars
and some pre 1988 Trucks and Motor homes
and by 1989 most all Vehicles had On-board Computer Engine and Emission Controls
~
Adjusting ~ Re-tuning ~ De-tuning
your older vehicle to run better using the newer lower octane fuels
as most older Cars and Trucks have a Standard Points or Electronic Ignition Distributor
and in most cases the Distributor will have both a Centrifugal and a Vacuum Advance
to advance the Ignition Timing as RPM increases
~
dis-connect the vacuum hose to the vacuum advance and cap off the vacuum source
and that is 99% of the battle
and this will allow the use of today’s lower grade fuels
with out having to use or add Octane Booster to the fuel
and prevent Damage to the older vintage engines still on the road
~
and in most cases you will then advance the base Ignition Timing
5* to 10 *
so you would adjust the base timing at Idle from 5* to 10 *
or from 10* to 15 *
or from 15* to 20*
so that when the Centrifugal Timing is at its Maximum Advance
as this will be in most cases above 2000 to 2500 RPM’s
the total measured timing advance does not exceed 28* to 32*
and follow up with an Idle Speed and Idle Air/Fuel Adjustment
of the Carburetor
while continuing to use today’s lower Octane non-Ethanol Premium Fuel
as in most cases the total timing advance before any changes ~ adjustments ~
will be about 45* total advance and in most cases causes pre-detonation ~ Pinging ~
on most older non-computer pre-computer engines
and this will prevent damage in most cases
while improving performance and fuel economy
without having to add Octane Booster
as this will lower the Explosion Temperature in the Combustion Chamber
and will lower NOx emissions too
NOx = Nitrogen and Oxygen bonding at 2500 Degrees and hotter
and then Sun Energy separates the Nitrogen from the Oxygen
making
O3 oxygen = 3 oxygen atoms together = Heavy Oxygen called Ozone
as Ozone at ground level causes Respiratory problems
as we are told we need more Ozone for the Ozone layer ?
whats good for Carbon based Humans is not always good for Nature and visa versa
