Oil Change Intervals, Synthetic vs High Mileage

You want your engine to last. Service is the lifeblood of an engine. The appropriate oil type and interval protect parts, keep deposits in check, and reduce wear. (Leave it to rush-hour Fredericksburg traffic, short trips, and summer heat  to wear your engine.)

What Does the Manual Say?

With most modern cars, the standard mileage range for synthetic oil or the oil life monitor is 7,500 to 10,000 miles.

For older vehicles, a 3,000-mile recommendation is typically provided, and in severe driving conditions, it may be even less.

Severe driving conditions include operating at speeds less than 5 miles per hour per trip, operating in dusty conditions, or experiencing frequent idling. 

Synthetic Oil vs. High‑Mileage Oil

Synthetic oil: Formulated and full-synthetic oils are designed for optimal protection against both heat and cold. They don’t break down or flow more slowly in the winter and can stand the turbo heat. Testing by AAA revealed that synthetic oils outperformed conventional ones by an average of 47 percent in industry-standard evaluations.

High‑mileage oil: Designed for engines that have accumulated many miles, usually 75,000 or more. Contains seal conditioners to help reduce oil leaks, as well as additives that help prevent seal breakdown. If you want the protection that synthetics offer and those conditioners, opt for a high-mileage synthetic.

FAQs

What exactly is an oil change?

An oil change is a vital part of vehicle maintenance. Over time, your engine will break down the motor oil due to high temperatures and the presence of contaminants. This oil is less effective as a lubricant and doesn’t help keep your engine cool as well. This degraded oil can lead to increased friction and possible engine damage. Not only do regular oil changes help extend your engine’s life, but they can also improve fuel efficiency. 

What happens when you change my vehicles oil?

At the most basic level, we drain the oil, allowing the old oil to drain out of the engine. Then we remove the old oil filter and replace it with a new oil filter. We then refill the engine with new oil as per the manufacturer’s recommendations. We then inspect to make sure there are no leaks and everything is done correctly.

What are some signs that I need an oil change?

First and foremost, the mileage since your last oil change is the most important indicator that you need an oil change. Other vital signs are:

  • Decreased fuel efficiency
  • Dirty or gritty oil
  • Louder than normal engine sounds
  • Burning oil smell or exhaust smoke
Will not changing the oil, harm my engine?

Yes, not changing your vehicle’s oil on a regular basis cannot only cause engine damage but also potentially destroy your engine. 

My car burns or leaks oil, should I fill it back up?

Yes, running an engine with low or no oil can cause catastrophic engine failure. Low or no oil can cause the engine to overheat, can cause blown gaskets and even complete engine failure.
