Mobil Pegasus ™ 1 is a high performance synthetic gas engine oil designed to meet the highest performance requirements of the most demanding stoichiometric and lean mix engines, both with and without turbo. It is made of wax-free synthetic base oils with a balanced additive system to provide a performance not possible with conventional mineral oil-based gas engine oils. The potential benefit is better overall financial result through increased engine and oil life, reduced maintenance costs and lower fuel costs. Mobil Pegasus 1's unique formulation minimizes ash deposits, piston crown and piston rings, valves and valve seats. It has excellent oxidation resistance and the naturally high viscosity index of synthetic base oil ensures protective lubrication film at temperatures well above what is possible with mineral oil based products. Due to its low volatility, Mobil Pegasus 1 helps to significantly reduce oil consumption and improve valve lubrication. The unique viscosity properties and the low traction coefficient provide improved performance and opportunity for improved fuel economy, especially at varying load, speed and temperature
