Run your car on LPG if you must, but don't forget to switch on the AC...
Rising fuel costs could have one very unexpected fallout – the increased risk of what’s being called the ‘Sick Car Syndrome.’ As fuel becomes more expensive, some motorists, in a bid to curb fuel consumption, avoid using the AC in their car. Using the AC increases fuel consumption by about 10 percent.
However, experts are now saying that car ACs should be should be switched on at least once a week, to help reduce the build up of fungal spores such as Cladosporium and Aspergillus, which multiply within a car’s ventilation system when the AC isn’t being used.
According to various research reports, the build up of bacterial spores in the air vents can cause health problems, particularly for those already suffering from asthma, when the system is finally used again. Those without allergies may notice a damp, stale smell each time the air-conditioner is switched on.
Also, failure to regularly use the AC increases the likelihood of mechanical failure – prolonged periods of non-use can cause the AC’s parts to seize or corrode.
