What's Leaking From My Car?

July 14th, 2016
You go out to your car, start it up, pull out of your parking space and see a puddle of...something...where you were parked a moment ago. This is never a good feeling. What could it be? 
 
Fortunately, some automotive fluids are dyed different colors to make this a little easier to narrow down. 
 
Does it appear to be water? Were you recently running your A/C? Chances are that's just condensation from the A/C system, which drips out through a rubber tube and is perfectly normal. No worries there. 
 
For years, antifreeze was dyed a bright green to make it easy to identify. Today, other antifreeze formulations can be colored pin ...[more]

A/C Problems Demystified

June 30th, 2016

Believe it or not, the A/C system in your vehicle is fairly simple in principle and design. Like your refrigerator, it operates on a cycle of compression and expansion of a gas, known as refrigerant. The compressor turns the gas into a liquid, and as the gas evaporates it provides cooling. Like your refrigerator, its main components are: 
 
  • Compressor
  • Condenser 
  • Receiver/dryer
  • Thermostatic expansion valve
  • Evaporator
  • Refrigerant
  • Blower 
The good news is most automotive A/C systems have become very robust and reliable compared to cars from a generation ago. Most of the time, poor performance is due ...[more]

So You Get A Flat Tire...What Now?

June 16th, 2016

Flat TireNobody ever looks forward to a flat tire, and nobody ever says "well, that was a really good time" after having one. You can at least minimize the damage to your tire and danger to yourself, though.

Flats vs Blowouts

If you get a blowout, you'll know about it right away. Sometimes the tire can fail dramatically, with a bang as loud as a shotgun going off. Other times, it might just be a loss of air and a sudden change in your car's handling, followed by vibration, noise and a pull to one side. If it's a front tire that fails, your car might be a real handful to drive until you can get to a stop.

In either case, your first job is to pull off the road as quickly (but safely ...[more]

Regular, Synthetic or Blend...What Kind of Oil Do I Need?

May 26th, 2016

At one time, there were only a couple of choices for motor oil. Today, that is no longer the case, and hasn't been for quite some time. Here's a quick breakdown of what you need to consider when it's time for an oil change:

  • Viscosity: Viscosity is how thick your oil is, and how it retains its pour properties at various temperatures. In this respect, synthetic oil is far superior. Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is much more uniform. Check your owner's manual -- many newer models require a thinner, lower-viscosity oil, which also helps the engine run more efficiently. Viscosity is expressed as a numerical value -- t ...[more]

The Latest in Green Tech Innovations for Tires

May 12th, 2016

When it comes to your car, oil isn't the only thing there's a finite supply of. Rubber has its limits too, and it's estimated by 2020, the supply of natural rubber in the world may be outstripped by demand. And of course, tires require a great deal of oil to produce as well. Tire manufacturers are constantly looking for ways to innovate and conserve resources in tire production. Here are some recent advances:

  • Dandelions: Yes, those humble yellow flowers you try to eliminate from your yard. Dandelions actually contain a minute amount of latex in their milky oil, and research shows they can actually produce about as much latex, pound-for-pound, as rubber plants. German scientists have cultivated 1-foot-tall dandelions for just this purpo ...[more]

4 Things About Tires You May Not Have Known

April 28th, 2016

Tires all look sort of the same…round and black…and people tend to think tires don’t change much over the years. That’s really not true, though – engineers and designers are constantly working on advances in tire designs for more miles, better fuel economy and better performance.

Here’s a rundown of current trends in tire technology you may not have been aware of:

  • Tall, skinny tires are coming back. If you’ve ever ridden a beach cruiser bike vs. a racing bike, you know that skinny tires have lower rolling resistance. Carmakers are going in that direction, too – the BMW i3 electric/plug-in hybrid uses Bridgestone Ecopia tires, with higher infla ...[more]

Cars That Last 250,000 Miles or More

April 14th, 2016

If you’re old enough, you probably remember the cars from the late 70s and early 80s that weren’t good for much more than 120,000 miles before they started to develop real problems and were junkyard bound. Today, thanks to improvements in design, metallurgy, manufacturing techniques and machining, those days are over and it’s not at all unusual to see vehicles with well over 200,000 miles on the odometer and still running strong.

Here’s a quick rundown of some vehicles to consider which have a track record of being good for 250k miles or more:

  • Toyota Corolla: Probably not a surprise to fans of Toyotas, the simple, no-frills Corolla hasn’t changed much since the early 00s…but Toyota’s approach to the tried-and-true Corolla ...[more]
