Read this post to find out what happens when you add synthetic oil to regular or “conventional” oil, the possible consequences of mixing engine oil types, and why getting professional help when switching from one motor oil type to another might be the smartest move.

Can You Mix Synthetic Oil With Regular Oil?

Yes, to make a long story short. Synthetic oil can help you out in a pinch if you’re stuck with no other option. But you should only use this as a temporary solution until you can get to the nearest oil change shop. Choose a professionally blended synthetic blend if you want to strike a balance between the advantages of synthetic oil and the affordability of conventional oil.

The base oil and additives used to make motor oils are usually the same, so mixing them together usually results in a compatible mixture. (All motor oil produced in the United States must comply with the American Petroleum Industry’s standards. be compatible with one another.) The differences mostly come down to the oil refining process. Even though conventional oil is less expensive than synthetic oil, it is less refined and can eventually cause more engine sludge and gunk buildup. While slightly more expensive, synthetic oil has fewer impurities than conventional oil, which can help it keep your engine cleaner and lubricated for longer. Since Pennzoil synthetic oil is not made from crude oil, it is actually even purer. It is a pioneering natural gas-based motor oil. In this video, find out more about the components of Pennzoil.

Remember that the advantages of higher-quality synthetic oil are diminished when it is combined with conventional oil. This not only decreases the value of your investment in synthetic oil, but it also might necessitate an oil change sooner than you had anticipated.

Also keep in mind that while all motor oils have the same basic components, they differ in terms of additives, chemical properties, and detergents. Combining different kinds can cause your motor oil to become unstable, lowering its effectiveness and impacting the performance of your engine.

The best option is to stick to the oil type and oil change schedule suggested by the manufacturer of your car and seek out affordable services from your neighborhood car care specialists. To ensure you use the right viscosity grade and performance recommendation for your vehicle, always refer to your owner’s manual.

Synthetic Oil

A petroleum-based base oil and evenly distributed, premium powder additives make up synthetic motor oil. Compared to other oils, this mixture is made to enhance engine performance and provide longer-lasting protection.

Synthetic oil is highly efficient over a wide temperature range due to its uniform properties, enabling quicker engine starts and longer intervals between oil changes. Its low impurity levels allow for cleaner burning and slower thickening, reducing engine drag. Synthetic oil also produces fewer emissions by preventing gum and varnish buildup, promoting better fuel economy by reducing friction.

Synthetic oils are ideal for older cars that don’t receive regular oil changes, as this oil can fend off contaminants and deposits, even when the vehicle isn’t in use.

Conventional Oil

Natural crude oil mined from the earth is where conventional motor oil is derived. Sedimentation is a method of oil refinement that gets rid of waste and impurities. The oil is finally heated until it vaporizes, leaving behind a base oil that is mixed with different liquids, including detergents, anti-oxidants, rust inhibitors, and dispersants. Which liquids are added to the base oil depend on the manufacturer.

For newer vehicles used for short-distance driving and light-duty tasks, regular oil works well because these activities are easier on the engine.

Can I Mix Oil Types?

The question of whether synthetic and conventional oil can be mixed safely is one that frequently comes up as synthetic lubricants continue to gain popularity.

Back in the day, I admit that I recklessly combined various motor oils. My Buick Century received a dash of synthetic blend to top it off one month and a shot of inexpensive conventional oil the following.

Although oil performance probably suffered, my engine never broke.

That’s because it’s safe to combine synthetic and regular oil. In actuality, synthetic-blend motor oil is merely a combination of conventional and synthetic oil.

Should You Top-off Your Car’s Oil?

To prevent engine trouble, it’s critical to maintain safe and sanitary oil levels. Many people accomplish this between oil changes by topping off their vehicle’s oil. Types of motor oil are frequently blended in this way.

While the occasional oil top-off is usually okay, getting an oil change is always the best way to keep your engine running smoothly. If you need to top off your oil, try to stick with the brand that’s already in there to preserve any advantages.

Always double-check the manufacturer’s suggested maintenance schedule, or go to a Tires Plus location to get all the advice on services and oil types without any pressure.

Switching Engine Oil Types

Consider switching to a different brand of motor oil. Visit the Tires Plus store closest to you and request an oil change using the Pennzoil oil of your choice to make the switch. Our trained technicians are prepared to respond to all your inquiries if you’re unsure of the type of oil that would be best for your vehicle.

Why It’s Not a Great Idea to Mix Synthetic and Conventional Oil

All motor oil, whether synthetic or conventional, is a combination of base oils and additives.

The impurities present in traditional base oils are eliminated during the manufacturing process of synthetic base oils. Additionally, synthetics frequently include higher-quality additives.

So, in the end, conventional and synthetic oils are comprised of the same, compatible components – it’s just that the components in synthetics are much higher quality.

What If You Have to Mix Oil Types?

In some circumstances, mixing the two might not be an option.

For instance, if you’re driving and discover that your engine is suddenly low on oil, the only choice at the gas station next to the highway might be inexpensive conventional oil.

While it’s safe to top off an engine that normally uses AMSOIL synthetic motor oil with conventional oil, we recommend changing the oil at your earliest convenience. In actuality, where oils have been mixed, AMSOIL does not support prolonged drain intervals.

Can You Use Regular Oil After Synthetic?

Yes, switching from synthetic to conventional oil is completely safe. Both types of oil contain compatible constituents, as was already mentioned; the base oils and additives in synthetic oil are just of a higher caliber.

Why would you want to use regular oil again, though, when synthetic motor oil offers better wear protection, engine cleanliness, fuel efficiency, and other advantages?

Possible Negative Effects of Mixing Conventional and Synthetic Oil

Mixing synthetic oil with regular oil is safe but can have numerous disadvantages for your engine:

  • More frequent oil changes: You’ll need to get your oil changed more frequently because mixing synthetic and conventional oil weakens the advantages of synthetic oil.
  • Reduced efficiency: Both conventional and synthetic oils contain various additives, chemicals, and detergents that, when combined, can destabilize your oil and affect how well your engine runs.
  • Lower value: Combining regular and synthetic oil reduces the value of your synthetic oil investment, so you won’t get the quality or performance you paid for.

Can You Use Regular Oil After Synthetic?

If you’ve been using synthetic oil in your car, you can switch to regular oil without any problems. Because both oils compromise compatible fluids, switching to regular motor oil is okay if your car has used synthetic before. Despite the fact that synthetic oil contains higher-quality ingredients, modern technologies make sure that these oils are sufficiently similar in their properties that there won’t be any issues when they are combined.

Final Words

No matter if it is synthetic or conventional, all engine oil is made up of base oils and additives. Synthetic base oils are manufactured using a process that removes the impurities inherent to conventional base oils and typically contain higher-quality additives. Overall, conventional and synthetic oils are made up of the same, compatible components; however, the quality of the components in synthetic oils is much higher. Although it is safe to combine synthetic and conventional oils, doing so only reduces the performance of the synthetic oil.

Sometimes, you might not have a choice. For instance, if you’re driving and discover that your engine is suddenly low on oil, the only choice at the gas station next to the freeway may be inexpensive conventional oil. While it’s safe to top-off an engine that normally uses AMSOIL synthetic engine oil with conventional oil, we recommend changing the oil at your earliest convenience. In fact, AMSOIL opposes long drain intervals in situations where oils have been blended.
