Motor Oil: Synthetic vs. Regular

Motor oil can be a confusing beast that results in a number of questions. Do I really need synthetic? Does my new car take conventional? Understanding the basics of the different types of oil will help you answer these questions.

Synthetic motor oils are designed to excel at extreme temperatures. Regular motor oils are mineral-based: they come from crude oil that is taken out of the ground and run through a refinery. Synthetics, on the other hand, are man-made in a chemical plant. They tend to be more consistent in viscosity over various temperatures.

While synthetics can improve your engine performance, they don't eliminate the need for regular oil changes. Synthetics can handle heat better than regular motor oil, but additives can only work for so long and the engine will still contaminate the oil.



Viscosity Simplified

You see those cryptic combinations of letters and numbers on motor oil bottles everywhere. What do they mean?  To decipher them, you have to understand viscosity. Viscosity measures how much the motor oil can resist flow. In other words, if you tip a motor oil bottle over, how fast it spills out indicates its viscosity. The more viscous, the slower it moves.

Knock, Knock. Wrong Octane!

Octane. You see the word every time you visit the gas station but what does it mean?  Octane ratings measure fuel's ability to resist engine knock. Engine knock is caused by fuel being ignited by something other than the spark plug.

Shedding Light on Halogen

Before you buy your next light bulb you should know the ins and outs of halogen bulbs!  Most new-model vehicles have halogen headlights because they produce more light than a regular bulb. Be careful: like all halogen lights, touching the glass bulb means that bulb is contaminated with oil that can heat up and cause burnouts more quickly.
 



A Breath of Fresh Air for Your Vehicle

This simple barrier of accordion-folded paper may look insignificant but it's responsible for providing clean air to your vehicle's cylinders.  This is important because air is just as crucial as fuel in the combustion process that powers the engine. Air is drawn through the engine air filter, then the air intake manifold and into the cylinders. There, it mixes with fuel to create the small explosions that power your vehicle.

A dirty engine air filter can prevent the cylinders from drawing in enough air, which throws off the fuel/air mix. This can result in poor fuel economy.
