Not only does thick, cold oil affect wear protection, it wastes energy. This, in turn, requires the engine to use more fuel. Because synthetic oils flow readily at start-up, synthetic oils improve fuel consumption.
In addition, modern low-viscosity oils, like 0W, flow more readily than the 10W oils vehicles once used. This, in turn, boosts fuel economy. But formulators must use synthetic base oils to manufacture low-viscosity oils that provide good protection in all areas important to your engine.
Several factors can cause your engine to increase motor oil consumption. Most are mechanical, including…. However, car engine oil volatility can also contribute to oil consumption.
The more volatile the lubricant, the higher the tendency to evaporate and exit the engine through the crankcase ventilation system. The more it evaporates, the less oil is left to protect equipment and the more often a user must replace the lost oil. The small, light molecules in conventional lubricants evaporate at relatively low temperatures. These light molecules require less energy in the form of heat than heavier molecules to be lifted out of the solution and into the air.
This thicker oil forces the engine to work harder, resulting in several problems, including the following:. Synthetic oils offer naturally better resistance to heat and volatility. As a result, they help reduce oil consumption to keep your engine clean and running strong. It stands to reason that synthetic oil will last longer than conventional oil due to its superior performance.
While synthetic oils in general outperform conventional oil, some synthetic oils are better than others. That means some will last longer than others.
Most synthetic oils can last 8,, miles. But some synthetic oils today are recommended for drain intervals up to 25, miles or one year. Changing oil once a year reduces waste oil and packaging considerably. Plus, it reduces time and money spent changing oil. How long a synthetic oil can last depend on its base oil and additive quality.
It also depends on whether your driving conditions fall under the severe or normal designation. Extending drain intervals in this way allows you to safely change oil less often while spending less on oil over the long haul, if you choose. Used oil analysis is the best method of determining how long your car engine oil can last. It involves taking and submitting an oil sample to a laboratory, where technicians analyse its condition for the presence of wear metals, coolant, fuel and other contaminants.
Oil analysis is the most efficient way to determine exactly how long your oil will last and when it needs changing. Remember the 3,mile oil change?
Wanting the best for your engine is a noble idea but throwing out perfectly good motor oil benefits no one except the company selling you the new oil.
The 3,mile oil-change interval was adopted and amplified in the s by quick lubes many of which were owned by oil companies. Car engine oil technology has advanced in lockstep with automotive technology, meaning oils today commonly last longer than the traditional 3, miles. As mentioned above, some synthetic oils offer the ability to extend oil drain intervals if you choose, saving time and money.
Yes, you can mix conventional oil with synthetic oil. There is no danger in mixing the two. Synthetic-blend motor oil, for example, which is readily available at any parts store, is nothing but conventional and synthetic oil already mixed in the bottle. In these cases, we recommend draining the oil at your earliest convenience and refilling with synthetic oil. Car engine oil, whether conventional or synthetic, is made from base oils and additives.
While these components are compatible with each other, the base oils in synthetic oils are higher quality. The additives, too, are often higher quality. Synthetic-blend oil is also referred to as semi-synthetic. Synthetic-blend oils fall in between conventional oil and synthetic oil on the car engine oil spectrum. The idea behind them is to offer drivers a taste of the improved performance of a fully synthetic oil at a price closer to a conventional oil.
Oil marketers see them as a stepping-stone product to help encourage motorists to eventually step up to a full synthetic. Ten percent? Unfortunately for drivers, there are no industry specifications or regulations that define the minimum percentage of synthetic components for a synthetic-blend to be classified as such. That being the case, astute drivers can look for a few clues to help interpret the amount and quality of the synthetic base oils in your synthetic-blend oil. Look for these two values:.
The additives also play a large role in fighting wear and deposits. Misinformation about synthetic oil vs conventional oil in older cars still populates the Internet and some auto repair shops. Or synthetic oils will cause roller followers to slip or skid. Conventional oil is derived from refined crude. The fact is that not all vehicle types are designed for other synthetic oils.
Furthermore, the mileage of a car plays a role. Engines are complicated enough already, but any mechanic will tell you that the age of an engine affects the grinding of gears in a car. According to these industry specialists, a car at 75, miles becomes more susceptible to wear and tear on its inner gears and moving parts, which the flow rate of oils can deeply affect. Since conventional oil flows slower than synthetic oils, it actually offers more protection to older engines. These vehicle types can start to consider conventional oil over synthetic options because it provides better lubrication for aging engines.
These thicker fluids reduce proper circulation and can become clogged on small areas on machinery. The oil in your car is a natural resource. Synthetic oils, however, are not naturally occurring compounds. These oils combine synthetic or artificial chemicals with crude oil to create a petroleum product that behaves similarly to conventional oil.
There are two types of synthetic oil: synthetic blend also known as semi-synthetic and full synthetic oil. The combination of conventional and synthetic oils produces synthetic blend oil. In the extreme environment of your engine, components can wear and break down. Your motor oil is the only protective barrier between these components. As conventional and synthetic blend oils break down, typically, their ability to prevent engine wear diminishes.
But Mobil 1 full synthetic oils retain their wear protection properties for a much longer time, helping to increase engine life by keeping important engine parts in excellent condition for , miles. Tested in vehicles primarily in city and highway driving conditions with respective product recommended oil change intervals.
As oil circulates through your engine, it can pick up deposits. Over time, conventional oils can form sludge, which can reduce your engine's efficiency and, ultimately, reduce the life of your engine. 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.
