Symptoms of Bad Gas in a Car


A gasoline-powered engine needs a combination of both gasoline and air in order to start and run. Clean, high-quality gas is necessary to maximize engine operation. Bad gas can seriously disrupt normal engine operation and cause a variety of performance-related symptoms.


Engine Pinging

  • A major symptom of bad gas is engine pinging, or knocking, which typically occurs as the result of poor or incomplete engine combustion. Bad gasoline, which is a term normally used to refer to gasoline that has a high water content or insufficient octane, does not ignite and burn inside the engine cylinders as well as high guality gasoline. This typically causes engine pinging, especially under acceleration when improper engine combustion becomes more pronounced.

Engine Dieseling

  • Engine dieseling occurs when a vehicle's engine continues to run erratically, or diesel, after the engine has been turned off. This can occur for a variety of reasons, but bad gasoline is one of the main causes. Bad gas with a high water content frequently causes incomplete and abnormal engine combustion, including abnormal combustion that sometimes occurs for several seconds following engine shutoff.

Reduced Engine Power

  • Bad gas does not combust and burn as well as high quality gas. As a result, bad gas typically results in poor engine performance and reduced engine power. Proper engine combustion is necessary for maximal engine power and performance. Any disruptions to normal engine combustion can reduce engine power and negatively impede normal engine performance.

Engine Hesitation

  • An engine will often hesitate, or stumble, during acceleration due to the effects of bad gas. Engine hesitation often occurs as the result of incomplete engine combustion, which can be caused by bad gas, in addition to fuel delivery problems and spark plug misfires. Typically, bad gas that has insufficient octane, which reduces its combustibility, is the most likely type of gas to produce engine hesitation.

Hard-Starting

  • A vehicle engine that is hard to start can often times be a symptom of bad gas. Ignition is dependent on a steady flow of clean, high-quality gas into the engine cylinders, where the gas is ignited by the spark plugs, which in turn causes an engine to start. Bad gas that is low in octane or high in water content can prevent or seriously retard initial engine combustion, which can cause hard-starting.

How to Find Out If My Car Is Being Tracked With GPS?

How to Find Out If My Car Is Being Tracked With GPS? thumbnail
A GPS transmitter can be placed on a vehicle and used to send signals about an individual's whereabouts. Some employers use transmitters to track employees in company vehicles, while parents use transmitters to track teen drivers, but some people illegally use tracking devices to stalk others. To determine if your vehicle is being tracked by GPS, you have to physically look for the transmitter. A GPS device placed by a professional can be more difficult to find. Professionals often place the unit within the car's electrical components so it doesn't look out of place.

Instructions

    • 1
      Look under the wheel wells of each tire. Sometimes GPS transmitters will be stuck in one of these places. A transmitter will be easy to spot here, so this place is usually not preferred by professionals who install tracking devices.
    • 2
      Find a GPS transmitter on metal surfaces. Some transmitters stick to the car with a magnet. Looking over all metal surfaces in the car and engine compartment could help you spot one of these types of transmitters.
    • 3
      Look in the spare tire. Depending upon your car, a spare tire could be located underneath the vehicle or inside the trunk. If you're looking at a tire inside the trunk, also look thoroughly in the spare tire compartment, which could be hiding the GPS transmitter.
    • 4
      Pull back loose interior pieces. Look for any loose pieces in the interior, which includes the trunk, that could be hiding a transmitter.
    • 5
      Look underneath the seats. The front sides can be physically removed, or you can use a mirror or flashlight to look underneath the seats for transmitter. The rear seat can be unhinged and removed. The rear seat is a good hiding place for a transmitter since so many people never remove the rear seat.
    • 6
      Check for a GPS transmitter in the glove box and other compartments in the interior. A novice may choose one of these spots. Make sure you open any envelopes or boxes that could be enclosing the transmitter.
    • 7
      Remove the car stereo and dash. A transmitter could be hiding behind the stereo or inside the dash. The dashboard can be difficult to remove, but it's an ideal place to place a GPS transmitter since it is so difficult to remove.
    • 8
      Remove the door panels and speaker covers. The door panels can be unhinged, but usually the door handles and knobs have to be removed before the panels can come off.
    • 9
      Open the hood and look around the engine, especially on the sides. To someone not familiar with car engines, a GPS transmitter can easily blend in. Carefully and slowly look over the entire engine. Use a mirror and flashlight to look in crevices. Get underneath the vehicle and look over the engine from the ground up.
    • 10
      Inspect underneath the entire vehicle. A mirror helps you to see underneath the entire car. A transmitter can easily be disguised within the metal, so you should perform this check several times.
    • 11
      Remove or look inside the bumper. You have to get underneath the car to see within the bumper.

How to Drive a Race Car

Dr. Talbot driving his Formula Ford race car

The unique challenges of race car driving can be difficult for young drivers. A race car travels at speeds in excess of 180 mph with frequent pit stops needed for refueling and tire changes. There are many tips to driving a race car along high-banked corners and past the competition to the finish line.

Instructions

    • 1
      Adhere to the basic tenet of driving by avoiding braking and turning at the same time. The act of making a left turn and applying brakes redistributes weight in your race car that can cause a slide out. Ease off of the throttle instead of applying the brakes on turns to stay in the race.
    • 2
      Keep your throttle steady until you reach the limit point in your race car. The limit point in racing is the exact spot at each turn where visibility beyond an angled corner is diminished by traffic.
    • 3
      Rest your back against your racing seat to maintain steady steering as you drive a race car. Your back should be flat against the seat to ensure your hands are resting on the steering wheel throughout the entire race.
    • 4
      Apply a slight amount of pressure to your brakes during a race to prevent locking during an emergency. Young drivers have the tendency to slam on the brakes which contributes to the sliding, skidding and locking responsible for most crashes.
    • 5
      Move away from a reliance on your side mirrors as you learn to drive a race car. The side mirrors are smaller on a race car than a regular vehicle to cut down on wind resistance. Learn to use quick head checks and forward vision to deal with changing traffic on the track.
    • 6
      Maintain inside position as long as possible to prevent passing on your left. Take advantage of the shorter distance on the inside lane by accelerating quickly and watching for competition on the outside.
    • 7
      Note the tendencies of fellow drivers during the first few laps to make quick decisions come crunch time. A smart driver will keep track of a competitor's tendency to bump, draft and pass to plan moves ahead of the final flag.

      Tips & Warnings

      Register at a racing school run by former professionals, such as the Mario Andretti Racing School, the Jim Russel Racing School or Danny McKeever's Fast Lane Racing School if you're really serious about learning. Check out RaceSchools.com for a listing of schools around the country (see Resources below).


      Test out your skills as a race car driver by taking your vehicle to an open day at a local track. These open days are designed for racing fans who want to get down on the track, meet drivers and see the challenges of the sport firsthand.


      Do not drive in a race until you are competent. You risk serious injury or death if you drive at high speeds without adequate experience and training.
