Can You Mix Conventional and Synthetic Oils? Fact or Myth?

Myth! You can often mix conventional and synthetic motor oils without causing serious damage to your engine. However, there are some important caveats to consider.

Understanding the Differences:

• Conventional Oil: Made from crude oil, it's refined to remove impurities and blended with additives. Conventional oil breaks down faster than synthetic oil, requiring more frequent changes.
• Synthetic Oil: Engineered from laboratory-created molecules, synthetic oil boasts superior performance, longevity, and cold-weather protection. It's more expensive but can often last twice as long as conventional oil.

Why the Mixing Myth Persists:

The myth likely stems from concerns about the different chemical compositions of the two types of oils. It's true that mixing some types of conventional and synthetic oils might lead to reduced performance or slightly increased wear. However, this is less likely with modern oils.

When Mixing is OK:

• Modern oils: Most modern oils, both conventional and synthetic, are formulated to be compatible. Check your owner's manual for specific recommendations.
• Emergency situations: If you're stranded and only have conventional oil, it's acceptable to top off your synthetic oil with a small amount of conventional oil until you can do a proper oil change.
• Short-term use: If you're only driving short distances, mixing conventional and synthetic oil for a short period likely won't cause significant harm.

When Mixing is NOT Recommended:

• Older engines: Older engines may be more sensitive to oil type and mixing could lead to problems.
• Different viscosity grades: Mixing oils with different viscosity grades (e.g., 5W-30 and 10W-40) can lead to improper lubrication.
• Significant mixing ratios: It's best to avoid mixing large amounts of conventional and synthetic oils unless absolutely necessary.

Important Notes:

• Consult your owner's manual: The most reliable source of information about the type of oil your vehicle requires is your owner's manual.
• Choose high-quality oil: Always use high-quality oil, regardless of whether it's conventional or synthetic.
• Perform regular oil changes: Regular oil changes are crucial for maintaining engine health.

Adding Value:

While mixing conventional and synthetic oils is generally acceptable in modern vehicles, it's always best to avoid it if possible. Sticking to the recommended oil type in your owner's manual will ensure optimal engine performance and longevity.
