I. Reuser: Gas engine development is pushing the boundaries of engine design so that operators can get the most out of their engine. All of these factors place significant demands on lubrication. The Mobil Pegasus™ 1100 Series is inspired by major OEMs and engineered to keep up with latest gas engine developments. It can help extend oil drain intervals by up to 1.5 times while also maintaining engine protection and cleanliness. The series itself consists of Mobil Pegasus™ 1105 and Mobil Pegasus™ 1107.
I. Reuser: Both lubricants have a well-balanced formulation helping to extend oil drain intervals (ODIs) by up to 1.5 times  when compared to conventional mineral oils.
Following comprehensive industry and bench testing, the lubricants exhibited excellent oxidation and thermal stability, which helps to extend oil life. The series’ outstanding anti-wear characteristics help reduce wear of engine components and scuffing of liners in highly loaded gas engines. In addition, the oil controls varnish formation and carbon deposits helping to maintain engine cleanliness.
This new product series is supported by the technical expertise offered through our Field Engineering Services. All of which is designed to offer customers effective lubricant solutions that ultimately help to improve their profitability.
I. Reuser: Crucial to our ability to stay up to date with the latest trends and meet changing customer needs is our close collaboration with Original Equipment Manufacturers. These oils are suitable for a range of OEM natural gas engines and appropriate OEM tests are underway - the results so far are very positive.
We were also pleased to announce that ExxonMobil is now a preferred global lubricants supplier for GE’s Jenbacher Type 2, 3 and 9 natural gas engines. As part of this new global collaboration, ExxonMobil will help owner-operators of GE Jenbacher gas engines enhance equipment performance through the use of its Mobil Pegasus™ family of premium natural gas engine oils.
The series is designed to protect today’s high output, low emission, four-cycle gas engines. Both products are designed for high severity natural gas engines and meet the specifications for all piston types.
I. Reuser: Europe is an important market for unconventional energy sources with more than 17,000 biogas plants recorded by the end of 2014. The rate of growth has been particularly strong in Germany and the UK.
In the face of new engine design developments and use of varying gas sources, energy companies have to react to these challenges. They can do this by offering smart solutions for gas engine operators, to help optimise performance and reduce maintenance costs no matter the geography – in Europe as well as globally.
I. Reuser: It’s an exciting time for gas engine development. The physical boundaries of engine design continue to be pushed, in an effort to increase power efficiency and reduce the cost of ownership. These changes directly translate into high demands for next generation lubricants.
The Mobil Pegasus™ 1100 Series has been specifically designed to keep up with the latest gas engine developments and feedback to date has been very positive. We look forward to sharing customer success stories in the near future.
 Mobil Pegasus™ 1105 and Mobil Pegasus™ 1107 are long life gas engine oils that have demonstrated up to 1.5X longer oil drain intervals versus competitor conventional mineral oils in high performance natural gas fuelled engines
