You know that winter and bad weather are coming. Is your car ready? Here’s a quick checklist of things to get up to speed on:
Motor oil: Motor oil has a tendency to thicken in cold weather, making it harder to circulate to upper engine parts at startup. If you haven’t ever used synthetic oil before, this might be a good time to start. The flow properties of synthetic oil are a lot more consistent, meaning it doesn’t thicken in sub-freezing temperatures or thin out when it’s hot outside.
Wipers: Even the best windshield wipers only last about a year. If your wipers are showing cracks or chips or losing strips of rubber, go ahead and replace them. Don’t forget to refill your washer fluid reservoir…you’ ...[more]

Nobody 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!) as you can. Don't jam on the brakes or make any sudden m ...[more]
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 -- the lower the number, the thinner the oil. Many are designed to work ...[more]
