In the past, changing your car oil was perhaps the simplest of maintenance tasks. Car owners did not have to spend a lot of time debating on what kind of oil to use since they did not have a variety to choose from. However, today, regular vs. synthetic car oil alternatives have changed everything. Every time you walk into an auto store, you need to ask for either regular or synthetic oil. For most car owners, this is never an easy decision.

What is Conventional Motor Oil?
Motor oil is a critical component of any vehicle using an internal combustion engine. Before the synthetic vs. regular oil debate, everyone used regular oil. Inside of a vehicle’s engine is many parts that move against each other, creating friction and converting energy to tremendous heat. When these pieces are not properly lubricated, fuel consumption is severely diminished, the vehicle will feel sluggish, and if neglected long enough – may lead to critical engine failure. Selecting the proper motor oil matters. For a majority of drivers, conventional motor oil is the perfect option. This is the standard, new oil used when a vehicle arrives for an oil change appointment.
Often, manufacturers will suggest two or more motor oil viscosities for an engine, like 5W-20 or 5W-30, based on a few factors – including temperature. Engines usually need different viscosity to accommodate various driving conditions. Viscosity is a fancy way to explain a fluid’s resistance to flow. A vehicle operating in Death Valley would need an oil with a higher viscosity (due to heat) than that same car in Alaska. Your vehicle’s user manual will be able to explain what type of oil(s) are most appropriate for your car and why it is recommended.

Advantages of Conventional Motor Oil:
• Cost Effective. If you are following a regular oil change schedule, and don’t typically push your car to its limits, you’re a prime candidate for conventional motor oil.
• Easy to Find. While the shelves offer more and more options for synthetic oil, conventional oil still reigns king. No matter where you go, a small local shop, or a major chain, you’ll easily be able to locate your preferred brand.
• Best Option for Older Engines. When a car has experienced significant action, like reaching 75,000 miles on the odometer, it is not recommended to use synthetic oil. Conventional oil moves more slowly through the engine, which means these gears are more thoroughly lubricated, and less likely to grind.
Making A Difference

What is Synthetic Motor Oil?
Synthetic oil is a man-made lubricant consisting of artificially made chemical compounds. Typically, these oils are created from chemically modified materials, like petroleum, but the base material is usually made from distilled crude oil. Any additives and the process itself for synthesizing the oil are closely guarded trade secrets among manufacturers. These oils are ideal for high-tech, sophisticated engines, but are being used by more vehicle manufacturers in order to achieve improved fuel efficiency.
Visually, conventional and synthetic motor oil looks the same, but fundamentally they are different. One major distinction is conventional oil is petroleum-based oil and is by nature thicker at low temperatures and thins at high temperatures. To address this variance, additives are included to change the oil’s properties which reduces the viscosity at lower temperatures while thickening the oil at higher temperatures.
On the other hand, synthetic oils are designed to behave like a specific type of multi-grade oil from the start. Synthetic 5W-30 motor oil will not degrade or change viscosity overtime however it may become slightly thicker from contaminants.
Advantages Of Synthetic Oil
- Advanced Formulation: Synthetic oil offers all-around weather engine protection and can be used in a variety of climates. From hot temperatures to cold, the additives and thicker consistency work in tandem to provide a better performance, while adjusting to the external temperatures.
- Longer Lasting: Once filled in your engine, you don’t need to replace it as often as regular oil. Unlike regular conventional oil, synthetic oil tends to last anywhere from 5,000- 7,000 miles before needing a proper change.
- Better Engine Protection: Its chemical formula along with the additives are designed to help remove, clean, and collect sludge build-up inside your engine.
Semi-Synthetic Oil
This particular oil is the hybrid of the two aforementioned oil types. This specific type of motor oil is also commonly referred to as a “Synthetic Blend.” The debate around synthetic vs. regular car oil is timeless. However, with the introduction of Semi-Synthetic Oil, car owners everywhere can now enjoy the benefits of both all in one bottle. The difference between full synthetic and blends is clear. While blends can operate at a variety of temperatures, they aren’t as regulated as full synthetics. This means that your engine’s performance will vary depending on brand, mix-ratio, and consistency.
Advantages Of Synthetic Blends
- Cheaper Pricing: No matter where you go, you’ll find that blends cost a little more than conventional oils, but are less expensive than many traditional synthetic oils. This allows quality protection while remaining affordable.
- Optimized For Colder Temperatures: Many studies show that blends outperform both full synthetic and conventional oils but only at low temperatures. But how exactly can this be? The answer is actually because of the mix between the two oils.
- Better Viscosity: The improved viscosity allows for a “middle of the road” scenario where both synthetic and conventional oil meet. This union between the two combines Earth minerals and engineered additives to flow in between tight spaces and help your engine.
What Oil Does My Car Need at Extreme Temperatures?
Due to synthetic oil’s formula, and mathematical engineering, it performs much better compared to regular oil in extreme temperatures, helping keep your car running smoothly, whatever the conditions. Engines are designed to produce heat whatever the circumstances; therefore, in high temperatures, synthetic oil will break down quicker.
Synthetic oils are also designed to resist heat and will break down slower compared to regular oil. In low temperatures, regular oil becomes thick and will take more time to warm up to ideal levels of viscosity. Hence, it won’t offer proper lubrication to fire up your engine correctly. Synthetic oil, on the other hand, is designed to flow smoothly even in low temperatures, protecting your vehicle in the process.
