To Use or Not to Use: Synthetic Oil and Your New Car
Many drivers are unsure whether they should use synthetic oil in their new cars. Synthetic oil has a number of pluses over regular oil: it can maintain integrity in heat; lubricates better; has fairly good purity; and rarely ever becomes sludge, even after abuse. Most drivers will see the obvious benefits synthetic oil has to offer and decide to use it in their car. However, even with the synthetic oil’s numerous benefits, the real difference is made in how you care for your car.
First of all, consider how regular you are with changing your oil. You car’s oil needs to be replaced every 3 to 5K miles, before it breaks down and potentially damages your engine. Synthetic oil is a great option for drivers who tend to forget or delay oil changes, since it is breakdown resistant, even after extended use. Drivers who dutifully change their oil on schedule, however, will probably never get any benefits from synthetic oil’s longer lifespan because it’ll never be used long enough to make a difference.
Synthetic oil can last a long time without deteriorating. If you’re changing your car oil based on mileage, then switching to synthetic could save you money. Regular oil needs to be replaced after 6 months or after 5K miles. If you drive less than that distance in 6 months, then you’re not getting the full mileage out of your oil. Switching to synthetic oil which lasts for a longer amount of money will help you get the most out of each oil change. You might save money by having to change your oil less frequently, and you’ll definitely save time.
One of the biggest reasons why people use synthetic oil is because of its resistance to heat. Regular oil breaks down in high temperatures, and continue to break down as the heat rises. Drivers who use their vehicles in ways that create a constantly hot engine environment should use synthetic oil. So should people who live in hot climates, such as in the desert, or at high altitudes, like in the mountains. Neither high ambient temperatures nor low air pressure are ideal conditions for keeping your engine cool, so synthetic oil would give you the best performance in these areas. Finally, if you own a high-performance vehicle or just drive like you do, consider synthetic, which is the best choice for these vehicles.
There are lots of people who will recommend synthetic oil to you, even if you don’t need it. For instance, synthetic is recommended for drivers who have to drive in stop-and-go traffic. However, almost everyone drives in this type of traffic at some time, and not everyone needs synthetic oil. It’s really only necessary if you’re stuck in stop-and-go for long periods of time, and on a regular basis. Synthetic might also be recommended to people who only drive on short trips, as a means for protecting the engine. But only driving for short trips will damage your engine regardless of what oil you choose, so the recommendation is redundant. Your engine is designed to perform for 20 minutes or more. There might be a slight benefit to running synthetic for short trips, but the difference is negligible.
If you determine that one of the above situations applies to you, take care when you purchase synthetic oil. Many places will suggest a synthetic blend as a way to save money (instead of full-synthetic), but the “blend” is oftentimes a mystery. Maybe you’re getting a 50-50 blend, or maybe you’re getting 1% synthetic and 99% regular oil. My recommendation is to go full synthetic or not bother with it - unless the blend suggested is provided and produced by your vehicle’s manufacturer.
Most car manufacturers will tell you that “any oil that meets API standard specifications can be used in your vehicle.” For most people, normal oil will be absolutely fine. As long as they are maintained regularly and cared for, most new cars won’t need synthetic oil to perform well for a long time.
