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]
Automotive technology has come a long way since the mid-20th century, and so has motor oil. A 1940s-era car didn’t feature an oil pump or oil filter. Instead, they relied on dippers on the crankshaft’s counterweights, which would then sling oil to coat crucial moving parts. Motor oils in those days weren’t designed with detergents and other additives to help keep the engine clean; even with frequent oil change intervals, many cars would be in need of an engine overhaul by the time they reached 80,000 miles.
Today’s motor oil formulations incorporate additives to suspend contaminants in the oil so they can easily be trapped by the oil filter. Here are a few other facts about motor oil you may not have known:
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]
The temperatures are inching upward, the days are getting longer and the first buds are starting to appear on the trees. Spring is on its way, and soon it’s going to be time to do a little preventive maintenance on your ride. No need to dread it -- it’s all pretty routine stuff!
- Air filter - If you haven’t changed your air filter since last year (or can’t remember when you changed it at all), it might be time. It’s an easy and cheap fix, and it pays off in your vehicle’s performance and fuel economy.
- Cabin filter - Older vehicles often don’t have a cabin filter, but it can make a lot of difference in how pleasant your vehicle is to drive. Stale, smelly air? Change it!
- Wipers -- Get a good look at them. Are they showing signs ...[more]
