Something to note before you dig in: conventional motor oil is extremely hard to find in your everyday auto shop. Most businesses that are selling you “conventional” oil, are probably selling you a synthetic blend instead. Be wary of trusting any place that sells “conventional” oil as the lowest price option. True conventional oil has become a boutique option and will be more expensive than a blend.
At LOF Xpress™ Oil Change, our lowest-priced oil is a 30% synthetic blend. The next level up is a full synthetic oil. This post breaks down the difference between true conventional and full synthetic oil. A synthetic blend will have some of the properties of both. We always want you to choose the best option for your vehicle. Most new vehicles require full synthetic oil.
Understanding the Difference Between Synthetic and Conventional Motor Oil
Maintaining your vehicle’s engine requires choosing the right motor oil, which is crucial. Many people ask us at LOF Xpress™ Oil Change about the difference between synthetic and regular motor oil. Both types of oil have their pros and cons, and understanding these can help you make the best choice for your vehicle.
What is Conventional Motor Oil?
Conventional motor oil is derived directly from crude oil and is the standard type of oil used in vehicles for decades. It acts as a lubricant, reducing friction between the moving parts of the engine, and helps to keep the engine clean by trapping dirt and debris.
Conventional oil undergoes minimal processing, which means it retains some of the natural impurities found in crude oil. These impurities can lead to the formation of sludge over time, especially in older engines. However, conventional oil is more affordable, making it a popular choice for many drivers, particularly those with older vehicles or those who adhere to more frequent oil change intervals.
What is Synthetic Motor Oil?
Synthetic motor oil, on the other hand, is engineered and refined through a more rigorous process. It’s designed to offer superior performance compared to conventional oil, especially in extreme conditions. The base oil used in synthetic motor oil is more refined, which means it has fewer impurities and a more consistent molecular structure.
This results in several key advantages:
Better Performance in Extreme Temperatures: Synthetic oil remains stable at both high and low temperatures, ensuring optimal engine performance whether you’re driving in the heat of summer or the chill of winter.
Enhanced Engine Protection: The consistent molecular structure of synthetic oil allows it to provide better lubrication, reducing engine wear and tear. This is because the viscosity of the oil is more consistent. It also resists oxidation and breakdown better than conventional oil, which means it stays effective for longer periods. Oxidation and breakdown happens naturally overtime as the oil mixes with oxygen. It causes the oil to thicken, losing its lubricating features. With synthetic oils, this happens at a much slower rate.
Improved Fuel Efficiency: Synthetic oil reduces friction more effectively than conventional oil, which can lead to better fuel efficiency. Over time, this can add up to significant savings at the pump.
Longer Oil Change Intervals: Because synthetic oil is more durable and resistant to breakdown, it generally lasts longer than conventional oil. This means you can go longer between oil changes, saving you time and potentially reducing your overall maintenance costs.
The Cost Factor
One of the main differences between synthetic and semi-synthetic motor oil is the cost. Synthetic oil is more expensive, which can be a deterrent for some drivers. However, it’s important to consider the long-term benefits. The longer oil change intervals, improved fuel efficiency, and enhanced engine protection can offset the higher upfront cost, making synthetic oil a cost-effective option in the long run. Once, conventional oil was the lowest cost. Now because it is hard to find, in some situations, it can be more expensive than even a full synthetic oil.
Which One is Right for You?
Choosing between synthetic and semi-synthetic oil depends on your vehicle, driving habits, and personal preferences. If you drive an older vehicle or stick to regular, frequent oil changes, a synthetic blend might be a suitable choice. However, if you want the best protection for your engine, drive in extreme temperatures, or prefer longer intervals between oil changes, synthetic oil is likely the better option.
It’s also worth noting that some newer vehicles require synthetic oil, so always check your owner’s manual or consult with your service technician to ensure you’re using the right type of oil for your car.
Understanding the differences between synthetic and semi-synthetic motor oil is essential for making informed decisions about your vehicle’s maintenance. While synthetic oil offers several advantages, the choice ultimately comes down to what works best for your specific needs and budget. At LOF Xpress™ Oil Change, we’re always here to help you navigate these decisions and keep your engine running smoothly.
