If I use Exxon Elite can I extend my drain intervals?
No. Regardless of the oil you are using, OEMs and the FAA require that standard oil drain intervals be maintained. That will not change with the introduction of Exxon Elite.


Can I mix Exxon Elite with conventional mineral oils – either monogrades or multigrades?
Yes you can, but you will not reap the full benefits of Exxon Elite if you mix it with other oils. In order to gain SAE J1899 certification, a lubricant must undergo compatibility testing that proves that it is compatible in any proportion with any other similarly certified oil. Accordingly, Exxon Elite is compatible with any certified ashless dispersant oil, including both monograde and multigrade oils. It is also compatible with break-in oils (SAE J1966) and can be used immediately following break-in.


Can I use supplemental additives with Exxon Elite?
While supplemental additives will probably do no harm, their use is not recommended. With the exception of the anti-wear/anti-scuffing additives required for some Lycoming engines, the claims made by manufacturers of supplemental additives are typically hard to prove or disprove.

Exxon Elite contains a proprietary formulation that carefully balances the properties of its base oils with the properties of its additives to ensure that the oil provides the protection you need, lasts long enough to get you to your next drain interval and is fully compatible with other certified products. Supplemental additives are typically an unnecessary added cost.


Will Exxon Elite help my engine make it to TBO?
There are a wide variety of factors that affect whether your engine makes it to TBO or even beyond TBO. According to Exxon's engineering tests, Exxon Elite's new formulation provides excellent protection against wear, corrosion and rust. In other words, it will do its part in taking you to TBO.


Are there any restrictions as to type/age of airplane for using Exxon Elite?
Exxon Elite can be used in any application requiring an SAE J1899 or MIL-L-22851D (obsolete) oil. Typically, the oil specification you need is determined by engine model and not by aircraft model. Therefore, Exxon always recommends checking your engine operating manual for information on oil requirements.


Do I need a special oil filter with Exxon Elite?
No. Exxon Elite requires no special filtration.


Will Exxon ever produce an extended-TBO oil?
Significant progress has been made over the last 20 years in extending TBOs from about 1,200 hours to the 2,000-hour specification that many engines enjoy today. This progress, however, did not occur as the result of changes in any single engine component or engine lubricant. The broad acceptance of ashless dispersant oils has certainly helped extend TBOs, but overall progress has been achieved through a variety of innovations. Any continued extension of TBOs, if it occurs, will likely be achieved in the same manner, and not just via a better oil.
