All motor oils are made up of base oils and additives. In general, fully synthetic motor oils contain non-conventional, high-performance fluids and a system of additives to help prevent wear, keep an engine clean, flow easily, maintain viscosity, prevent rust and reduce friction. The result is a lubricant that remains liquid and slippery under the widest possible range of temperatures and engine conditions.
You should follow the same environmentally sound procedures that you do with conventional motor oil. The U.S. Environmental Protection Agency's (EPA) guidelines for disposal include:
Do not dump used motor oil in the trash.
Do not pour it on the ground or down the sewer or storm drain.
Place the used motor oil in a closed container.
Take it to a service station or a collection location that recycles used motor oil.
Do not burn the used motor oil in a space heater.
To make it easier to recycle, do not mix motor oil with other substances, such as gasoline or antifreeze.
To locate proper disposal locations in your area, use the Earth911 search.
Many Exxon and Mobil service stations will take used motor oil from do-it-yourselfers and will follow EPA-approved recycling. Please note that it is acceptable to mix used Mobil 1 with used conventional oil.
ExxonMobil offers two synthetic motor oils for motorcycles. Mobil 1 motorcycle oils have been specifically optimized for motorcycle applications, including transmission clutch performance and high-temperature operation such as air-cooled operation. Be sure to follow your owner's manual for recommended oil and filter change frequencies.
The performance of Mobil 1 is more robust, especially in terms of low-temperature pumping and flow compared to conventional oils. High-temperature stability leading to the protection against deposits is also superior. These attributes translate into less engine wear, to help keep your engine running like new, and a long engine life. Conventional oils lack the performance of synthetic oils in the areas of low-temperature performance and high-temperature oxidation stability. The mineral base stocks used in conventional motor oils also contain significantly more impurities, such as aromatics and other undesirable contaminants that cannot be completely removed by conventional refining of crude oil.
Mobil 1 is fully compatible with conventional motor oils, semi-synthetic motor oils and other synthetic motor oils, should it be necessary 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.
