Benefits of synthetic oil

There are two basic types of lubricants available:

  1. Conventional mineral oils are the traditional types.
  2. Synthetic lubricants, which are growing in popularity.
 
Conventional oil begins in the ground. It’s simply refined crude oil. But synthetic motor oil (whether full synthetic oil or a synthetic blend oil) is born in the lab.
Synthetic oil is not only refined but also distilled, purified and broken down into its basic molecules. It is then rebuilt and enhanced with additives so that it can better protect against engine wear, extreme temperatures and sludge build up. This process not only removes more impurities from the crude oil but also enables individual molecules in the oil to be tailored to the demands of modern engines. These customised molecules provide higher levels of protection and performance and can keep your engine running better for longer.
As oil circulates through your engine it can pick up deposits. Over time, conventional oils can sometimes form sludge, which can reduce your engine’s efficiency and, ultimately, reduce the life of your engine. Synthetic motor oils contain fewer impurities compared to conventional motor oils and can better resist the formation of sludge, thereby preventing deposits from forming in your engine.
Engine parts are in constant contact with each other. They’re also moving at high speeds. In the extreme environment of your engine, components can wear and break down. Your motor oil is the protective barrier between these components. As conventional oils break down, their ability to prevent engine wear diminishes. Synthetic oils, on the other hand, retain their wear protection properties for a much longer time, increasing engine life.
When your car sits for a while (let’s say overnight) the oil settles when you fire up the ignition, it begins flowing through critical engine parts to protect against friction. With conventional oils, it takes more time until they are able to flow smoothly through the engine.

During the cold winter months, or if you live in an extremely cold environment, this flow process takes even longer. Synthetic low viscosity oils, however, are engineered to flow quickly even at low temperatures, and they start protecting your engine right after you start your car.
When running, engines are hot. Really, really hot. Over time, the high temperatures in your engine can cause conventional motor oils to break down or evaporate exposing your engine to wear. Synthetic motor oils are engineered to resist these high temperatures, which is especially important if you’re driving in hot climates.
To meet consumer demand, automakers are building cars with smaller engines (for greater fuel efficiency) but adding turbochargers (to boost power). We already mentioned how engines run at high temperatures, which can break down conventional oils faster, but today’s turbocharged engines are even more aggressive. The shaft inside a turbocharger can spin upwards of 200,000 revolutions per minute, so it’s critical that your motor oil can get to that shaft and lubricate it properly very quickly.

Conventional oils can break down faster under these conditions and leave deposits on turbocharger components, which can lead to failure. Synthetic oils can protect these components much better than conventional oils, keeping them operating at peak performance and boosting your engine’s power.

Fuel economy and greenhouse gas regulations have changed the way engines are built. Due to a heightened focus on increasing mpg, smaller four-cylinder engines with complicated systems –hybrid, stop-start and turbo –are now replacing larger six-and eight-cylinder engines. Turbocharged engines have emerged as the answer to vehicle manufacturers’ needs to deliver fuel efficiency without sacrificing power. 

We already mentioned how engines run at high temperatures, which can break down conventional oils faster, but today’s turbocharged engines are even more aggressive. While engine crankshafts average about 3,000 rpm at motorway speeds, the turbocharger shaft can reach speeds up to 200,000 rpm. Additionally, the oil in a turbocharger can exceed temperatures of 200⁰C, which is about twice the average heat of non-turbocharged engines. Such high speeds and temperatures can cause some motor oils to decompose, resulting in more engine deposits and diminished performance. Synthetic oils can protect these components much better than conventional oils, keeping them operating at peak performance and boosting your engine’s power.

Mobil 1 oils are setting the standard for turbocharged engine performance and protection.

Mobil 1 oils resist breakdown by delivering outstanding oxidation stability and thermal protection down to -40⁰C and up to 260⁰C. When used in turbocharged applications, Mobil 1 oils offer exceptional: 

  • Protection of thrust bearing
  • Varnish control on shaft bushing 
  • Deposit and build-up control on the compressor, compressor seal plate and turbo housing
More than 70 of the top performance vehicles, many of which feature turbos, roll off factory lines with Mobil 1 oil inside. From Mercedes-AMG to Porsche, vehicle manufacturers trust Mobil 1 oil as the factory fill and recommended service fill to help protect their modern turbocharged engines.

  • What is synthetic oil?

    Motor oils aren’t created equal. You might already know that synthetic oils outperform conventional oils, but you might not know the difference between synthetic blend oils and fully synthetic oils.

  • Why choose a synthetic oil?

    Your engine is a complex machine with hundreds of moving parts that operate under a wide range of temperatures and stressors. The oil you select needs to be equally capable of coping with these operating conditions to protect your engine.
