There is a clear and vocal demand in Kerrville and nationally for a reduction in air pollution and our dependence on fossil fuels. This is what is driving the Texas market for alternative fuel vehicles. There are a number of these vehicles on Luling area roads today, and many more being developed. Yet each of these vehicles has its own advantages and disadvantages. Kerrville car owners should learn what these advantages and disadvantages are before running out and purchasing one of these alternative fuel vehicles at your nearest Luling dealership.
Luling auto owners should carefully research the car care before buying an alternative vehicle, as it may or may not coincide with the standards for gasoline vehicles. You should look at costs and gas mileage as well: these vehicles may help save our environment here in Kerrville, but that might not represent a savings to your wallet. You’ll need to decide what you can afford, and what will work for your lifestyle. Also, your choice of vehicle may be affected by what fuels are available in your Luling area. Switching to an alternative fuel vehicle is not a bad decision, but it should be a carefully considered one.
Flex Fuel Vehicles
Flex fuel vehicles can run on gasoline or on a combination of 85% ethanol and 15% gasoline. Because of the 85% ethanol content, this fuel is commonly called E85 in Texas.
Ethanol is made from corn. So flex fuel vehicles lessen our dependency on fossil fuels. But they also raise the price of corn, which is a basic foodstuff in some areas of the world. Whether replacing fossil fuels with corn is a good idea is hotly contested right now.
Flex fuel vehicles do have lower harmful exhaust emissions than gasoline-powered vehicles. And in Luling, E85 is usually lower in cost than regular gasoline. When gasoline prices fall in Texas, however, they can drop below the price of E85. This is to Kerrville drivers’ advantage, since the vehicle can run on either fuel, but it negates the benefits of lowered exhaust emissions and lower consumption of fossil fuels.
One piece of Texas Express Lube & Auto auto advice before we move on: do not put E85 into your truck unless it has an engine designed for flex fuels. Because of the high ethanol content in E85, engines need special seals and gaskets to function properly on this fuel. Running an ordinary engine with E85 can lead to gas leaks and fires.
Diesel engines are nothing new on Texas interstates, and many get great fuel efficiency. Diesel fuel can now be made from vegetable oil and other renewable sources. A diesel fuel made from algae will soon be on the market in Luling.
Natural gas is less expensive than gasoline in Kerrville and burns more cleanly. Also, gasoline engines can be adapted to run on compressed natural gas, and many natural gas vehicles are already on Centerpoint roads. You can even install a special pump in your home gas line to use to fuel your vehicle. If you are interested in converting your gasoline engine to run on CNG in Kerrville, ask your Texas Express Lube & Auto service advisor about it.
On the other hand, an engine running on natural gas is not as powerful as one running on gasoline, and it will get lower fuel efficiency. Also, the tank you need to store natural gas is large—it takes up nearly the entire trunk of your car. Further, refueling stations are still few and far between in some Texas areas, or even unavailable, in many parts of the country.
Another alternative fuel that has enjoyed a lot of hype in Luling is the hydrogen cell. The natural appeal is that the only exhaust is water vapor. In other words, hydrogen represents a truly clean-burning fuel. But hydrogen vehicles won’t come into widespread use until refueling stations become widely available here in Kerrville and around the country.
Electric vehicles were all the rage in Texas some years ago. But their limitations were quickly realized by Kerrville car owners. These vehicles won’t come into their own until we find ways to improve their batteries. Currently, the cars have a short range before their power runs out, and can only be realistically used close to home. However, they are easy to recharge, since they can be plugged in at home, and there are many researchers working on improving the battery technology in these vehicles. They may yet be the vehicles of the future.
Hybrids have been one of the most successful alternative fuel vehicles here in Kerrville and throughout the county. A hybrid gets its name because it has both a gas or diesel engine and an electric motor.
There are two types of hybrids. The full-hybrid relies on the electric motor for power, but the gas (or diesel) engine generates power for the battery. Thus, while still consuming fossil fuels, it uses less of them than a standard automobile, and also reduces harmful pollutants. Also, it overcomes the range problem of the strictly electric vehicle.
In a mild hybrid, the electric motor assists the gas or diesel engine in powering the car. Thus, it uses more gasoline or diesel than full hybrids and has higher emissions. But mild hybrids are available in larger body models like full-size pickups and SUV’s.
A Note of Caution about Hybrid and Electric Vehicles
One last note before we leave the subject of alternative fuel vehicles. The battery in an electric or hybrid vehicle is not as tame as the one in a standard vehicle. They carry enough voltage to kill you. These are not do-it-yourself vehicles when it comes to preventive maintenance or car care. Only a trained technician should work under their hoods.
