  1. Does Motor Oil Expire?

    If you change your own oil, the chances are you’ve got some old engine oil on your shelf. Likely it’s nothing more than an opened 1-liter top-up bottle, or an unused 4-liter bottle. You then wonder, "Does motor oil expire?" WHAT DO THE OIL COMPANIES SAY? There is a general consensus of terminology coming from the oil companies that unused, unopened, and stored in its original container out of extremes of temperature, motor oil will last for an “extended period”. They then go on to suggest...

    Windshield Dots

    The small black dots on a car windshield are called frits, which are black painted enamel that’s baked onto the surface of the glass. Modern cars have a windshield bonded to the frame. He described how the windshield is bonded using a strong and long-lasting urethane adhesive, which makes the windshield a structural component of the vehicle’s body. The frits “provide a secure point of contact between the glass, urethane adhesive, and windshield frame. Essentially, the small black dots help...
  3. Blind Spot Monitoring

    What is Blind-Spot Monitoring? Blind-spot monitoring one of those features we didn’t know we needed or wanted until carmakers began offering it. Volvo was the first, incidentally. It offered its Blind Spot Information System (BLIS) for the S80 in 2005. BSM is just what its name implies. It keeps an eye on the space just off the rear quarter areas of your vehicle. These blind spots can hide a vehicle approaching in an adjacent lane because many drivers improperly set their car’s outboard...
  4. Li-Ion Batteries

    We are now entering the electric car age. These vehicles are powered by Li-Ion batteries. This type of battery is energy dense and durable. However, it can also be unstable and prone to catching fire under certain circumstances. But not all Li-Ion batteries are suited for vehicles. How Do They Work? Lithium ions store the energy by creating an electric potential difference between the negative and positive poles of the battery. Those are isolated using a separator material to prevent...

    Prochargers

    In a previous article, superchargers and turbochargers were discussed in detail (see link, below). Superchargers vs. Turbochargers | Dodge Challenger Forum Anyone who goes to the track, or watches the cable TV show, Street Outlaws, knows that many knowlegable racers are going to prochargers. In fact, Ryan Martin, switched his Fireball Camaro from twin turbos to prorchargers. Watch his interview at the 2:30 minute mark. Prochargers, superchargers and turbochargers are all different...
  6. Wind Tunnels

    When most people think of wind tunnels, an aerospace tunnel usually comes to mind. This helps designers and engineers understand how aircraft will behave during various flight conditions. Automotive wind tunnels are usually very similar to aerospace tunnels, but they often feature a rolling floor that lets test engineers simulate a car driving on the road at various speeds. What are Wind Tunnels? Wind tunnels are large tubes with air blowing through them which are used to replicate the...
  7. Security Devices

    As you know, there has been an ongoing problem concerning the theft of high performance Dodge cars, notably Hellcat and Scat Pack Challengers and Chargers. Security devices are now more important than ever. They can be categorized as follows deterrent devices, anti-theft devices and tracking devices. Deterrent Devices Alarm System Alarm systems are only effective in areas where they will attract immediate attention. And unless the alarm is unique, it will be ignored. If you want to add...
  8. Window Tint

    Window film (a/k/a, tint) is a thin laminate film that can be installed to the interior or exterior of glass surfaces in automobiles. It is usually made from polyethylene terephthalate due to its clarity, tensile strength, dimensional stability, and ability to accept a variety of surface-applied or embedded treatments. Window films are generically categorized by their construction components (dyed, pigmented, metallized, ceramic or nano), by their intended use (automotive, marine or...
  9. Ethanol Fuel Mixtures

    The question frequently comes up, “Are E10 and E85 fuels harmful to my engine?” Here is everything you wanted to know about the chemical compound ethanol that is added to gasoline. Ethanol is used as an “oxygenate” and is added to fuel to help reduce hydrocarbon emissions that cause air pollution. It is highly refined beverage (grain) alcohol, approximately 200-proof, that can be produced from natural products such as corn, sugar cane and wheat. New technology allows ethanol to be made...
  10. Burnout Primer

    All drag racers spin their wheels in a burnout before every race. The burnouts may seem to be pure show-boating, but there are real reasons behind all the smoke and noise. Burnouts before a drag race serve to heat the tires of the car, softening the rubber, providing more traction for the start of the race. The burnout also removes any debris from the tires. Spinning the wheels leaves a layer of rubber on the road surface, providing better traction in the future. The burnout is crucial for...
  11. Tips for Car Shows

    Winning a car show is great satisfaction. The real reward, however, is having a group of knowledgeable people say that they respect your style, taste and hard work. If you’re one of those people that take car shows seriously, here are a few tips that might help you win. Before The Show The Build- Restoring or Modifying Your Car Some owners rack up their credit cards doing things to their cars for the sole purpose of “checking off that box” on the judges’ score sheet. The funny thing is,...
  12. The Advantages & Disadvantages of Lowering Your Car

    Cars come with conventional-size and strength springs that help it deal with potholes and bumps on the road. Manufacturers have spent considerable time and money to come up with just the right suspension components. Nevertheless, it has become fairly common for car owners to modify their cars’ suspensions to make them ride lower. Usually aesthetics are one of the most important reasons for reducing ride height- many people prefer the appearance of a lower car- but there are other...
  13. How Rev Limiters Work

    Simply put, rev limiters restrict the maximum speed an engine can achieve. They are there to prevent an engine from damaging itself by extending beyond its limits. Any engine is only designed to be able to function up to a certain speed, which is measured in revolutions of the crankshaft per minute. Out of the factory, the rev limiter is set at the point the engine’s maker is happy for it to rev to on a regular basis. It’s not to be confused with the redline, although it can sometimes be...
  14. Electric and Hydrogen-Powered Cars

    Stellantis is finalizing its 5-year and 10-year plans. According to Automotive News Europe, newly appointed Alfa Romeo CEO Jean-Philippe Imparato told Italian journalists, during a roundtable event, that all future vehicles from the company would be electrified. They will be built on a new platform known internally as the STLA large-vehicle architecture that will be shared across brands under the Stellantis umbrella. Tim Kuniskis, in a recent Autoweek interview, was quoted as saying, “I...
  15. Threadlocker Adhesives

    Threadlockers, as the name suggests, are used to lock the threads of fasteners such as screws, bolts, studs of different sizes which are used in different applications- especially automotive. This type of adhesive prevents loosening caused by vibration, mechanical and thermal shock. Chemically speaking, most thread-locking formulas are methacrylate-based and rely on the electro-chemical activity of a metal substrate to cause polymerization of the fluid. Thread-locking fluid has unique...
