Oil Changes: What are the 3 types of oil?

User Rating:  / 0

Regularly scheduled oil changes are important to keep the moving parts of your engine lubricated.  A reliable auto mechanic will recommend an oil change on a regular basis to prevent excessive engine wear and tear and to keep your vehicle functioning efficiently.

Basic facts to know before your next oil change:

Grades: The Society of Automotive Engineers (SAE) grades each type of oil according to how thin or how thick it is.  The higher the grade–-up to 70–-the higher the viscosity (or thickness). These grade numbers are referred to as the weight, including the most common weights of 5W-30, 10W-20 and 10W-30.

Viscosity: This is an important factor in determining which type of oil is right for your car. Too thin and it won’t lubricate the engine parts well enough when it heats up. Most vehicles can use “multi-viscosity” oil which has passed the SAE specifications--thinner at lower temperatures, and thicker at higher temperatures.  When choosing the proper type for your next oil change, you will want to consider the range of temperatures in which you drive your vehicle.

Here are the differences between the three main types:

• Conventional: Organic and limited in its capabilities, and highly reactive to temperatures.

• Synthetic: Gives better engine performance, more slippery, and has fewer imperfections in its chemical buildup.  Synthetic can cost up to three times as much; but the interval between oil changes can be greater longer.

• Synthetic blend: Combination of conventional and synthetic, is usually less expensive, but provides the same performance enhancement as a synthetic.

If you still have questions when it’s time for an oil change, it is best to follow your vehicle’s manufacturer’s recommendations.  For the final say, consult your local auto mechanic--they’ll know what’s right for your vehicle.
