Mobil 1 full synthetic oils contain fewer impurities compared to conventional and synthetic blend oils and can better resist the formation of sludge and deposits in your engine.
If your engine already has sludge, Mobil 1 motor oils clean up virtually all engine sludge in just one oil change. When your vehicle is not being driven, the oil settles. But when you fire up the ignition, it begins flowing through critical engine parts to protect against friction. Conventional and synthetic blend oils take more time until they are able to flow smoothly through the engine. During cold winter months, or if you live in an extremely cold environment, this flow process takes even longer.
Mobil 1 full synthetic oils are engineered to flow quickly even at low temperatures, and they start protecting your engine right after you start your vehicle. When running, engines are hot. Over time, the high temperatures in your engine can cause conventional and synthetic blend oils to break down or evaporate, exposing your engine to wear.
Automakers are building cars with smaller engines for greater fuel efficiency and turbochargers to boost power. Turbocharged engines run even hotter than non-turbo engines. Conventional and synthetic blend oils can break down faster under extreme turbo conditions and leave deposits on turbocharger components, which can lead to failure. Mobil 1 full synthetic oils can protect these components much better than conventional oils, keeping them operating at peak performance and boosting engine power.
Yes, generally, synthetic oil can provide longer oil change intervals than conventional oil. But this is often dependent upon the brand of motor oil and several other factors, such as driving style and driving conditions.
Please follow the recommendations in your owner's manual while your vehicle is under warranty. Some synthetic motor oil brands still recommend oil changes every 3, or 5, miles. This stratifies certain additives which can potentially lead to their complete separation from the oil. Multi-grade motor oils using synthetics may exhibit slightly less fuel economy at highway speeds compared to mineral oil.
This is due to the fact that mineral oils require more viscosity index improvers an additive than synthetics. This additive contributes to reduced viscosity friction by a mechanism known as shear-induced temporary viscosity thinning. Synthetic Engine Oils: Digging Deeper Synthetic oil used in motor vehicles is refined from base oils or base stock oils. PAOs are the most common type of synthetic base oils used today thanks to their moderate price and little negative attributes.
PAOs are Group IV base oils and are similar to mineral oil in their chemical makeup but the fact that it's built rather than extracted makes it purer. The benefits of PAOs include improved oxidation and thermal stability, low volatility potential to change rapidly , good heat dissipation, low pour point temperature below which a liquid loses the ability to flow and it's free of waxy molecules. Esters- a Group V base oil made from ester oils is created from the reaction of acids and alcohols with water molecules splitting off.
The most common esters used for synthetic motor oil are diesters and polyol esters. Diesters are commonly used as an additive with PAO base stock oil. Esters have high thermal stability and excellent low pour point characteristics but poor hydrolytic stability the resistance of a cured polymer material to going back to a semisolid or liquid form when exposed to high temperatures and humidity. May not bear API service classification marks. Additive stability in cold temperatures for extended periods of time may be a problem.
Fitch When Synthetics Always Makes Sense As mentioned, extreme conditions and worst-case scenarios demand the use of synthetics. Below are the passenger car applications that are ideally suited for synthetics motor oils: High-performance engines. There are many examples of high-end sports cars and even SUVs where the investment is high, as is the expectation of engine performance and reliability. High-performance driving.
If you are involved in motor sports, then you will pay a premium for a competitive edge - power, endurance and engine reliability. Luxury car engines. Some luxury sedans are so expensive, it would clash with common sense to use anything other than a synthetic. Extreme cold starts.
Extended drains. Towing and high loads. Slow speed, high load e. It's in these cases that oil films get extremely thin and high wear rates can ensue. This can be offset using premium synthetics with the best additive packages. Long engine life. The vast majority of the driving public have never owned a car with more than , miles on the engine.
Many of us are genuinely not compelled to share the experience. Yet there is a large number of auto enthusiasts out there who try to get every last mile out of their car. About the Author Jonathan Trout. Jim Fitch. The processes used to make synthetic oils allows oil companies to remove impurities otherwise found in crude oil. They can then tailor the oil molecules to meet the specific demands of modern engines. Thanks to this level of customization, synthetic oils provide superior levels of protection and engine performance than conventional oils.
While synthetic oils offer superior performance, they are substantially more expensive per volume than conventional motor oils. They also pose potential problems in terms of decomposition in certain industrial environments.
Most synthetic oils are rated to last between 10, to 15, miles, or six months to a year. In such cases, it may be a good idea to change your oil sooner than your rated mileage recommendations. For any feedback or correction requests please contact us at research caranddriver.

Synthetic Oil: Overview Artificially created lubricants are often used as a substitute for petroleum-based oils, which are required to operate in extreme temperatures. Synthetic Oil vs. These higher quality base oils make synthetics: Less likely to acidify and oxidize More chemically stable Harder to break down and lose desired qualities Consumer Reports says that fully synthetic oils provide superior engine protection and performance over any synthetic blend or conventional motor oil.
What is the difference between synthetic and conventional oil? First, the way the oils are made create a clear distinction. Reduced degradation when towing or hauling heavy loads. It also contains superior additives that are meant to help prevent degradation of the oil over time. Other synthetic oils start out as a petroleum product, like conventional oil, but undergo a special refining process that changes the molecular structure to meet certain criteria, such as operating at high temperatures and lasting longer than conventional oils.
High-performance vehicles, especially those equipped with turbochargers, which require oils that can withstand high temperatures, are more likely to call for synthetic oil. However, automakers are moving toward wider use of synthetic oils or synthetic-blended oils, which are usually less expensive.
