Aviation
Throughout history, ideas on advancing aviation lubricant technology have taken flight at Exxon Mobil.
Ever since the Wright Brothers made aviation history in 1903 with a Mobiloil in their plane's four-cylinder engine, aviators have been using our lubricants.

As we celebrate the first 100 years of aviation, our products have logged about 80 billion flight hours in worldwide aircraft operations. None of our products has traveled as far or often as Mobil Jet Oil II, our flagship gas turbine engine oil.
Mobil Jet Oil II is a "Second Generation" or "Type II" synthetic lubricant and the first of its kind to be U.S military approved against MIL-PRF-23699.
Our flagship oil has an extensive history of trouble-free performance in modern aircraft-type turbojet, turbofan, turboprop and turboshaft gas turbine engines.
Ongoing laboratory and field tests consistenly demonstrate that Mobil Jet Oil II helps control engine deposits better than competitive Standard Type II lubricants.
Today many commercial airlines and military services, and dozens of executive aircraft fleets are experiencing the benefits of using Mobil Jet Oil II.
What are you using to protect your fleet's jet engines and accessories? If you are looking for a product that can help control engine deposits and reduce maintenance, there is really only one choice : Mobil Jet Oil II.

Our oils have been protecting aircraft engines since 1903. Mobil Jet Oil II helps control deposits, keeping gas turbine engines cleaner and operating more efficiently. We make, blend and package Mobil Jet Oil II in ExxonMobil-owned plants, ensuring product quality and consistency. Mobil Jet Oil II has a history of providing trouble-free performance. Mobil Jet Oil II can mean less maintenance, greater revenue.

Mobil Jet Oil II helps keep aircraft where they belong: in the air generating revenue.
Demands on aviation oils have come a long way since the Wright Flyer's four-cylinder engine.
In 1927, When Charles Lindbergh completed the first solo nonstop transatlantic flight in history, a Mobiloil was lubricating the Wright Whirlwind J-5C engine that powered his "Spirit of St. Louis". Even then we were working with engine manufacturers to enhance our lubricant's formulations to meet the demands of newer designs.
A Mobiloil protected "Friendship" when Amelia Earhart made her historic solo flight across the Atlantic. And when Wiley Post became the first aviator to circle the globe solo, his aircraft's engine was also lubricated with a Mobiloil.
Today's modern jet engines require a lubricant that can handle extreme speed, temperature, and other stress without breaking down or forming deposits. Our Mobil Jet Oil II is tailor-made to meet these challenges. Even NASA selected the proven protection of our jet engine lubricant. Mobil Jet Oil II is made from a highly stable polyol ester basestock and unique chemical package proven to help:
- Control engine deposits better than other Standard Type II commercial aviation oils
-Keep the oil system clean
-Extend engine, gear and bearing life
-Reduce engine maintenance
