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 a ...[more]
Summer is here, and it’s time to start thinking about your car’s AC system! Nobody likes driving around in a hot, stuffy car, and a car with an AC system which only works marginally is somehow almost even worse than one which doesn’t work at all. Let’s go through a few tips which can help you keep your ride a little more comfortable this summer…
Remember a cars AC system is really a heat exchanger which moves hot air out of your vehicle, then replaces it with cold air. One thing you can do to help improve its efficiency is to leave your windows down an inch or two (if possible) when you park the car, helping to prevent excess heat buildup. When you start the car and begin to drive off, lower all the windows for the first minute or two to help move hot air out of the car more quickly, giving the AC system a chanc ...[more]
Often, drivers are mystified by how their cars actually work. It’s to be expected. Even an older car is a complex machine with many sub-assemblies that all work together to move it down the road.
As a result, drivers tend to be a little intimidated by auto repair and often tend to not inform themselves by asking the necessary questions of a tech or a garage. Too often, that ends up being a big mistake. Here are some examples of the kinds of things you really should know before any auto repair work starts:
- Does your shop work on any kind of vehicle? Of course, most shops can service a product from GM, Ford, Chrysler, Nissan, Toyota and the other leading makes. Some makes, however, require a lot more training and experience, o ...[more]
