All engine oils are made of base oils and additives. A synthetic lubricant contains more highly refined base oils than conventional mineral oils, offering you superior protection and performance. Synthetic engine oils provide a variety of benefits that keep your engine running at optimal performance for years, such as help to prevent wear, keep an engine clean, flow easily, maintain viscosity, prevent rust and reduce friction.

You should follow the same environmentally sound procedures that you do with conventional engine oil. Please contact the Environmental Protection Authority or the relevant regulatory body for more detailed guidelines on disposal.

All engine oils are made of base oils and additives. Fully synthetic engine oils contain 100% non-conventional, high-performance fluids. Semi-synthetic engine oils (also called "blends") contain a smaller percentage of these high-performance fluids in combination with conventional mineral oil. Mobil 1™ is a fully synthetic engine oil.

You get an unsurpassed level of engine protection. Back in 1974 when Mobil 1 was launched, it was the first widely available automotive synthetic lubricant on the market. Today, there are others but Mobil 1 is still universally acknowledged to be the most advanced. Learn here about Why Mobil 1?

Mobil 1 is fully compatible with conventional engine oils, semi-synthetic engine oils and other synthetic engine oils if you need to mix them. However, it is important to note that the superior performance of Mobil 1 will be reduced by diluting it in any way.

Free-flowing Mobil 1 starts protecting as soon as you start your engine, making it the perfect choice if most of your driving involves short journeys. If most of your driving consists of short journeys - the quick trip to work, the school run, or down to the shops - your engine hardly has time to warm up before it is turned off again. To save engine wear, you need outstanding cold start protection. In tests, it has been proven that Mobil 1 still flows freely at temperatures as low as negative 40°C and it can reach all moving parts of the engine 15 seconds faster than some conventional oils at start-up. That means Mobil 1 starts protecting your engine straight away, saving it from a great deal of punishment, and saving you money on fuel and maintenance costs. And, of course, it also means more reliable starting, even on the coldest mornings.

Outstanding protection even at the most extreme temperatures makes Mobil 1 ideal if most of your driving is high speed motorway cruising. If you often drive long distances at high speeds, your engine will get extremely hot. And, needless to say, fuel economy will be a matter of great importance to you. The Million Mile Test and the Drive Around the World proves that no matter how long the journey, Mobil 1 can virtually eliminate engine wear; keeping your engine in almost the same condition as the day it was fitted. That means your engine won't only continue to perform at its peak, it will also run more efficiently and use less fuel.

Tried and tested at the highest levels of motorsport, the World's Leading Synthetic Engine Oil is simply the only choice for the enthusiastic driver. If you enjoy driving and performance really matters to you, that means you place extreme demands upon your engine. Using the right lubricant can make a significant difference, in terms of increased power output. What's more, you will enjoy the reassurance of knowing that your engine has the ultimate protection, no matter how hard you drive it.

While Mobil 1 costs a little more than other engine oils, for the simple reason that it costs rather more to produce, its unique formulation is the result of an enormous ongoing investment in research and development.

The short answer is a resounding yes. The unsurpassed protection provided by Mobil 1 technology, powerfully demonstrated by the Million Mile Test, can keep your engine in virtually the same condition as the day it was fitted; potentially averting significant maintenance costs. Just as important, free-flowing Mobil 1 conserves energy in your engine, giving you better fuel consumption. So, while Mobil 1 may cost you more upfront, it can save you money down the road.
