Sentron CG40 Gas Engine Oil

4-Stroke Cycle Natural Gas Engine Oil

  • Longer oil life provides long-lasting equipment protection
  • Extended drain interval can reduce maintenance and provide savings
  • Outstanding anti-wear/anti-scuff protection
  • Keeps engine parts clean
  • Extremely low oil volatility

Petro-Canada SENTRON CG40 natural gas engine oils (NGEO) are premium performance, long life engine oils specially formulated to lubricate natural gas engines and compressors. SENTRON’s extended drain intervals can mean lower maintenance costs, less used oil to dispose of and a more efficient and profitable operation. SENTRON’s exceptional performance is especially important in the severe service conditions common in compression, power generation and combined heat and power applications. Its outstanding anti-wear protection helps to minimise polish and wear of cylinder liners and wear of piston rings, while helping to reduce carbon buildup.

That can mean:
Longer service intervals
Cleaner engines with less wear
Less downtime
Less backfiring
Fewer service calls

SENTRON CG40 natural gas engine oils are formulated with Petro-Canada’s ultra pure HT Severely Hydrocracked base oils and highly advanced additive technology to help deliver a combination of extended oil life, extended drain intervals and excellent control of engine deposits. Offering exceptional protection against wear and corrosion, SENTRON helps provide worry-free operation, increased engine durability and engine life, which can lead to a reduction in overall operating costs.

SENTRON natural gas engine oils span the typical levels of sulphated ash and SAE viscosity grades required by gas engine manufacturers. Moreover, they have a proven track record of successful use under a wide range of operating conditions

SENTRON CG 40 (0.93% wt ash) is designed specifically for 4-stroke cycle gas engines running in severe service such as co-generation, sewage or sour gas or low halogen landfill gas operations. SENTRON CG 40 gives exceptional performance in turbocharged, naturally aspirated rich and lean burn gas as well. As it contains low levels of phosphorus and zinc, it may be suitable for use in engines equipped with certain catalytic converters. Check with your Technical Services Advisor for suitability.
