Alcohol In Gasoline – Short Term Effects
As antique vehicle owners we experience first-hand the problems
associated with the modern alcohol fuels. Vapor lock, stalling, poor
acceleration, and hard starting (caused by the fuel evaporating in the
fuel line before the mechanical fuel pump), are all symptoms we are
familiar with. The alcohol is also an aggressive solvent that will
loosen varnish and gum deposits in the gas tank and fuel system. That
will in turn plug fuel filters, and affect the operation of the idle
jet, needle and seat, and float in the carburetor.
Alcohol In Gasoline – Long Term Effects
When antique vehicles are placed in long-term storage (6 months or
more for example) the alcohol in the gasoline will draw moisture (up to a gallon a
year) from humidity and temperature changes, and thru places like the
vented fuel cap.
In as little as sixty days the alcohol will begin to
separate from the gasoline and the newly formed mixture of alcohol and
water will settle in the bottom of the fuel tank where it begins to
loosen the rust and corrosion on the inside of the tank. The mixture
will also attack welded seams and any thin places in the tank (corners)
eventually causing the tank to begin leaking fuel. (The alcohol can also
damage rubber fuel lines from the inside out, Which is why you need to replace your rubber fuel line with the new barrier fuel hose.)
If the pickup tube of your gas tank is in the bottom of the tank as
most antique vehicles are, you will get the alcohol and water mixture
instead of the gasoline when you try and start your car after it has
been in long -term storage. Testing the gasoline yourself is the only
way you will know for sure, what is in the bottom of your fuel tank.
By the way that accumulation on the bottom of your fuel tank works excellent for plugging up fuel filters, needle and seats in carburetors. It can also keep you antique vehicle from starting or cause it to run poorly. That is because you are trying to burn a mixture of alcohol and water.
