Mobil Pegasus 1107 increased oil drain interval and reduced oil consumption
MWM TCG 2032 B 4.5 MW gas engine | CHP at Textile Dyeing and Finishing Plant | Portugal
Situation
ExxonMobil and its Authorised Distributor completed a Mobil ServSM Optimum Drain Interval Study for Caterpillar, operating a Combined Heat and Power (CHP) engine at a textile dyeing and finishing plant. The company had the ambition to improve their productivity with less downtime caused by oil drains, reduce engine interactions and decrease safety hazards related to frequent oil and filter changes on their MWM TCG 2032B V16 engine.
Recommendation
Based on the findings of the drain interval study, Caterpillar was advised to upgrade to the high performance gas engine oil Mobil Pegasus 1107 and start oil condition monitoring via Mobil ServSM Lubricant Analysis (MSLA) to extend the oil drains without compromising protection of critical engine parts and components.
Benefits
The transition to Mobil Pegasus 1107 and Mobil ServSM Lubricant Analysis resulted in the following benefits:
- oil drain interval (ODI) increased by 67% (from 1800 h to 3000 h) when compared against the previous oil
- oil consumption decreased from 0.35 g/kWh to 0.22 g/kWh, which meansa decrease by 37%
- the decrease in the specific oil consumption and the extended ODI has helped to decrease the waste oil disposal by 40%
- annual oil filter consumption has been reduced by 70%, leading also to reduced wasted spare parts management and filter cost reduction
