Show original supplier description
The Mobil Pegasus 1 is a high-performance synthetic gas engine oil specifically engineered for the most demanding naturally aspirated and turbocharged stoichiometric and lean-burn gas engines. Formulated from wax-free synthetic base oils and a meticulously balanced additive system, it delivers performance that surpasses conventional mineral oil-based gas engine oils. This advanced formulation minimizes critical engine issues such as ash deposits, piston land and ring belt deposits, liner scuffing, and valve seat and valve face wear. It offers outstanding resistance to oxidation and provides a robust protective lubricant film at high temperatures due to the inherently high viscosity index of its synthetic base oil components. Mobil Pegasus 1 also exhibits low volatility, which helps reduce oil consumption and improve valve lubrication performance. The state-of-the-art technology in Mobil Pegasus 1 ensures a high level of engine performance across a wide range of high-output gas engines. Its exceptional oxidation resistance and thermal stability contribute to extended service life for both the engine and the oil. Furthermore, the unique properties of Pegasus 1 lead to lower internal friction during cold start-ups and hot running conditions, resulting in reduced wear and potentially lower fuel consumption. This translates into lower maintenance costs through extended service intervals, reduced filter expenses, and an overall improvement in engine longevity. Key features include a balanced synthetic formulation for extended drain intervals and cleaner engines, outstanding oxidation and thermal stability for reduced deposits, and excellent high and low-temperature performance for reliable lubrication in all conditions. Its naturally high viscosity index ensures wide temperature performance, while low volatility reduces oil consumption. Exceptional anti-wear and anti-scuff protection is provided, and a low traction coefficient offers potential for fuel cost savings and improved engine power.
