Foul Fiero
With all of the concern about indoor air quality (IAQ) these days, you may
have noticed a foul odor emanating from your Fiero's air conditioning. It may
smell like a locker room, and it doesn't just smell bad, it may be hazardous to
your health. The air entering into your car, when you operate your car's A/C,
passes over the A/C evaporator (the cooling element). When you operate the A/C,
water condenses around the evaporator coils. Moisture vapor can also collect in
the ducts of the system once the car is no longer running due to the cool
surfaces of these components relative to the outside air. This moisture collects
airborne pollutants such as dust, dirt, pollen, spores and germs. It also
provides an environment for bacteria, dust mites, and fungi to grow. These nasty
critters create the bad odor that blows out of your dashboard vents.
Many newer cars are equipped with micro filters that catch pollutants from the
air before it enters the car. However, the odor from thriving bacteria and fungi
will still remain. There are two ways to combat this problem. There are
commercially available products designed to cleanse the HVAC system. The
products are generally sprayed into the exterior air intake vents and inside the
interior vents. For maximum effectiveness, this should be done annually. In
conjunction with this, it is advisable to leave the car open when parking after
using the A/C. Leave the sunroof open or crack the windows to allow air movement
through the car. Adequate ventilation prevents the environment from becoming
favorable for the growth of odor causing and sometimes-harmful bacteria and
fungi. (Source: autopia)
Combating Rising Gasoline Prices
Just as many of us bring our Fieros into the light of day to enjoy cruising
around, the cost of fuel begins its assent into the stratosphere. The Midwest,
of all places, was subjected to the highest gas prices in the nation last year.
In the Detroit area we had to pay $2.50 or more for regular (87 octane)
unleaded. The rumor was that gas prices were to top out at $3.00 per gallon this
year, but thankfully, that didn't happen! There is one way to combat high fuel
prices. Don't buy more octane than you need.
Many people believe that "premium" gas is the best gas you can put in
your car. Premium simply means that it has the highest octane rating, and the
highest unit cost. Octane is a measurement for a gasoline's ability to resist
premature ignition. What this means to an engine is an ability to resist knock,
rattling and pinging resulting from premature ignition of the compressed
fuel-air mixture in the cylinder.
Most gas stations offer three gasoline grades; regular at 87 octane, mid-grade
at 89 octane, and premium at 92 or 93 octane. Some stations offer and economy
grade at 85 octane. The rating is required by law to be posted on the pump. It
is usually a yellow decal next to each grade. The misunderstanding about octane
is that the higher the octane, the more power, performance, smoothness, and fuel
economy will be realized. Premium gas does not have any more potential energy
than regular grade. The octane grades are designed to accommodate various
compression ratios of various engines. High compression engines found in
performance cars require a fuel that burns at a higher temperature. Use of a
lower octane in these engines will result in diminished performance due to
premature ignition prior to the piston reaching its full upward movement and
thus less than full compression, resulting in less power. Premium fuel used in
an engine that is not designed for high-octane gasoline results in unburned
fuel, excess carbon build-up and fouling of the plugs. The result is an engine
that is actually less efficient.
Our Fieros, with stock engines, are designed to operate using regular unleaded
gasoline. So not only do we have fuel-efficient cars that are fun to drive, we
also get to pay the least amount for gasoline. Keep the extra change to buy some
Fiero parts! (Source: autopia)
Bad Habits Die Hard
We all like to think we are Steve McQueen in Bullet as we traverse the
countryside in our manually equipped Fieros. It sounds great and provides some
satisfaction that we have more control over our cars than those driving slush
boxes. We love to downshift. But downshifting to slow a vehicle is a bad habit.
Realistically you should be using your brakes to slow the car. Downshifting is
appropriate when selecting the proper gear to exit a curve or turn, or when
attacking a steep grade. However downshifting to slow a car results in
additional wear on the clutch, transmission synchronizer rings and crankshaft.
Clutches and transmissions are expensive to repair, with a clutch replacement
costing in the $600 to $1,000 range. Compared to the replacement of the brake
pads, the savings may be enough to make you 'brake' a bad habit.
