Common Oil Change Questions Answered At Andrew Toyota

September 23rd, 2015 by

Despite it being relatively inexpensive, having your oil changed regularly and on schedule plays a critical role in preserving your vehicle and saving you money. Here at Andrew Toyota Scion, it is important to us that you understand every aspect of your vehicle’s maintenance. Below are some common oil change questions to help Toyota and Scion owners.

Why are oil changes important?

Oil is the lifeblood of your vehicle. It keeps the many components of the engine working efficiently, and it helps reduce the accumulation of varnish and carbon from collecting on the engine. As oil collects heat, varnish and carbons during the course of protecting and keeping the engine running smoothly, it eventually becomes less like liquid and more like sludge. No matter how good the oil is, eventually it degrades as the additives get used.

 

What do the oil change numbers mean?

When looking at what oil your vehicle takes in your manual your will some numbers on the labels like 10W-30 or 10W-20. These numbers represent the viscosity, which is the resistance to flow of the oil. The number next to the W indicates the viscosity when the oil is cold and the other number represents the viscosity when the oil is heated. The higher the viscosity number is, the more resistant it is.

 

What is the difference between types of oil?

There is a variety of motor oils all with specific blends for different vehicles. To see what type your vehicle takes, please review your vehicle’s owner’s manual:

  • Conventional oil: This oil is often used in older Toyota vehicles. While conventional motor oil is cheaper, it does not last as long as synthetic oil. Conventional oil also does not hold up well in extreme weather conditions such as Wisconsin’s winters.
  • Full synthetic oil: This artificial oil is made for high-tech engines. It also gives you the best performance – it flows in all temperatures and leaves almost no deposits behind. Although this oil can be more expensive, it can last up to three times longer than conventional oil, which means it will pay off in the end. It is also beneficial to the efficiency of your engine and can even enhance your fuel economy. All new Toyota and Scion vehicles use a version of a synthetic called: synthetic lubrication standard (SAE 0W-20). Toyota’s transition to low viscosity synthetic oil is intended to provide the following benefits to our vehicles, the environment and you, our valued owner:
    • Maximized emission performance on cold start-ups
    • Enhanced engine protection in a wide variety of operating temperatures
    • Reduced environmental burden on recycling and disposal of waste oil
    • Lower cost of ownership through improved fuel economy and extended oil drain intervals
  • Higher mileage oil: This oil is formulated specifically for older vehicles with more miles on them. It benefits older cars by helping to prevent oil from leaking with its special formula so you will not have to add oil as often because of a leak. These oils also contain a higher viscosity to give your wearing engine better performance.

 

What are the oil change intervals using this new oil? Are they longer?

Yes, the superior qualities of synthetic oil have allowed the oil change interval to be extended from 5,000 miles to 10,000 miles. Be sure to check with your Andrew Toyota Service experts to ensure proper maintenance is being performed.

 

Even though oil change intervals have been changed to 10,000 miles for 0W-20 vehicles, does that mean I do not need 5,000 interval mile services?

No, although your vehicle may not require oil changes as frequently the “Maintenance Required” indicator light will continue to illuminate every 5,000 miles as an important reminder of the need to have other maintenance performed. Regular inspection/rotation of your vehicle’s tires and inspection of your vehicle’s brakes, which generally do not wear out at prescribed intervals, helps ensure your vehicle’s safety.
