Is full synthetic better than blend?
When it comes to choosing the right motor oil for your vehicle, the debate between full synthetic and synthetic blend often arises. As the owner of Kevin's Autos, with years of experience in car maintenance and repair, I’ve seen firsthand how the choice of oil can impact a vehicle's performance and longevity. In this article, we’ll break down the differences between full synthetic and synthetic blend oils to help you make an informed decision.
What Is Full Synthetic Oil?
Full synthetic oil is a highly refined motor oil designed to provide superior performance and protection for your engine. It is chemically engineered to have a uniform molecular structure, which allows it to perform better under extreme conditions. Full synthetic oil is often recommended for high-performance vehicles or cars that operate in extreme temperatures.
What Is Synthetic Blend Oil?
Synthetic blend oil, as the name suggests, is a mixture of conventional motor oil and synthetic oil. It offers some of the benefits of full synthetic oil, such as improved performance and protection, but at a lower cost. Synthetic blends are a popular choice for drivers who want better performance than conventional oil but don’t want to pay the premium price of full synthetic.
Key Differences Between Full Synthetic and Synthetic Blend
- Performance: Full synthetic oil provides superior lubrication, reducing engine wear and improving fuel efficiency. Synthetic blends offer moderate performance improvements over conventional oil but don’t match the capabilities of full synthetic.
- Cost: Full synthetic oil is more expensive than synthetic blends due to its advanced formulation. Synthetic blends are a more budget-friendly option.
- Longevity: Full synthetic oil lasts longer between oil changes, making it ideal for drivers who want to extend their maintenance intervals. Synthetic blends require more frequent changes.
- Temperature Resistance: Full synthetic oil performs better in extreme temperatures, whether hot or cold, making it a better choice for harsh climates. Synthetic blends offer decent resistance but may not be as reliable in extreme conditions.
Which One Should You Choose?
The choice between full synthetic and synthetic blend depends on your vehicle, driving habits, and budget. Here are some scenarios to consider:
- If you drive a high-performance or luxury vehicle, full synthetic oil is likely the best choice to ensure optimal engine performance and protection.
- If you frequently drive in extreme temperatures or tow heavy loads, full synthetic oil’s superior temperature resistance will benefit your engine.
- If you’re looking for a cost-effective option that still offers better performance than conventional oil, a synthetic blend is a great middle ground.
- If your vehicle manufacturer specifically recommends full synthetic oil, it’s important to follow their guidelines to maintain your warranty and engine health.
Conclusion
Both full synthetic and synthetic blend oils have their advantages, and the right choice depends on your specific needs.

Frequently Asked Questions
Is fully synthetic oil bad for old engines?
Modern synthetic oil is safe to use in all types of vehicles, ranging from new purchases to classics to aging not-so-classics. The idea that synthetic oil could harm old engines probably comes from a time before synthetic oils had been extensively tested.
Why can't you go back to regular oil after full synthetic?
Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine. Of course, this depends on the current engine condition and the quality of the conventional oil being used.
What is the disadvantage of fully synthetic engine oil?
Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.
Which synthetic oil is the best?
List of the Best Synthetic Motor Oils
- Mobil 1 Extended Performance Synthetic Motor Oil. This is our top pick for numerous reasons.
- Royal Purple High-Performance Synthetic Motor Oil.
- Shell ROTELLA Full Synthetic Diesel Engine Oil.
- Pennzoil Ultra Platinum Full Synthetic Motor Oil.
- Valvoline MaxLife High Mileage Motor Oil.
Is synthetic blend good for high mileage?
High-mileage oils are usually synthetic oils. They are typically based on either full-synthetic oil or a blend of synthetic and conventional oil. Synthetic oil offers greater protection in extremely high temperatures, and its ability to flow easily in cold weather helps make engine starts easier in freezing weather.
Is full synthetic actually better?
Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can't compete with the overall engine performance and protection provided by synthetics.
Is it bad to switch between full synthetic and synthetic blend?
Yes, it is generally okay to switch from synthetic blend oil to full synthetic oil. Here are a few points to consider: Compatibility: Synthetic blends and full synthetics are compatible, so you can mix them without causing issues. However, for optimal performance, it's best to fully drain the old oil before switching.
When should you not use full synthetic oil?
Fully Synthetic oil is mostly only suitable for modern cars of about 15 years old maximum, don't use fully Synthetic oil in a very old engine and most important always use the oil that is recommended in your owner's manual.
Does full synthetic oil burn faster?
Synthetic oil typically burns slower than regular mineral oil. This is because synthetic oils are engineered to have uniform molecules and fewer impurities, resulting in better lubrication properties and higher stability at high temperatures.
Should I get synthetic blend or full?
Current statistics show that nearly half of all cars, trucks, and SUV's require synthetic blend or full synthetic oil. So which one is better? The short answer is full synthetic is always better, but cost is the main reason why you may want to buy high mileage oil vs synthetic oil.
