殼牌555航空渦輪發動機潤滑油產品說明：

　　殼牌555航空渦輪發動機潤滑油是一種先進的5mm2/s 受阻的酯類合成油，以提高熱和氧化穩定性，并提高基礎油的承載能力相當均衡的混合油。

　　殼牌555航空渦輪發動機潤滑油應用：

　　殼牌555航空渦輪發動機潤滑油是專門為滿足高溫和承載的SST引擎和DEF STAN91-100（原DERD2497）和XAS-2354規范的要求而開發的。殼牌555航空渦輪發動機潤滑油也被設計給當前發動機性能的增強。

　　最近在需要通過直升機傳動系統和變速箱系統傳輸更多的動力和更高的負載情況下（很多直升機在傳輸/變速系統中使用合成渦輪發動機油），很明顯，使用很好的承載油，如殼牌555航空渦輪發動機潤滑油是很有必要的。這反過來又導致了美國軍事規格的發展，美國國防部L-85734，其中涵蓋了直升機變速箱油對殼牌555航空渦輪發動機潤滑油的完全批準和認可。

　　AeroShell Turbine Engine Oil 555

　　AeroShell Turbine Oil 555 is an advanced 5 mm2/s synthetic hindered ester oil incorporating a finely balanced blend of additives to improve thermal and oxidation stability and to increase the load carrying ability of the base oil.

　　Applications

　　AeroShell Turbine Oil 555 was specifically developed to meet the high temperatures and load carrying requirements of SST engines and the DEF STAN 91-100 (formerly DERD 2497) and XAS-2354 specifications. AeroShell Turbine Oil 555 was also designed to give enhanced performance in current engines.

　　More recently with the need to transmit more power and higher loads through helicopter transmission and gearbox systems (many helicopters use a synthetic turbine engine oil in the transmission/gearbox system) it has become apparent that the use of a very good load carrying oil, such as AeroShell Turbine Oil 555 is necessary. This in turn has led to the development of a U.S. Military Specification, DOD-L-85734, which covers a helicopter transmission oil against which AeroShell Turbine Oil 555 is fully approved.

　　AeroShell Turbine Oil 555 contains a synthetic ester oil and should not be used in contact with incompatible seal materials and it also affects some paints and plastics. Refer to the General Notes at the front of this section for further information.
