SENTRON™ Stationary Gas Engine Oils (SGEOs) are premium performance, long life engine oils specifically designed to lubricate stationary gas engines and their integrated compressors, running at gas plants and pipeline compression stations, as well as in power generation, cogeneration, bio gas, landfill and sewage gas operations and in crude oil production operations.
SENTRON™ SGEOs are formulated with three different sulfated ash levels:
SENTRON™ ASHLESS 40 | Ashless - less than 0.1% wt ash |
SENTRON™ CG 40 PLUS, LD 3000, LD 5000, LD 8000, LD Synthetic Blend VTP 0W-30, VTP 10W-40, VLA 40 |
Low Ash - 0.1 to 0.6% wt ash |
SENTRON™ CG 40, SP 30, SP 40, VTP 10W-40 Plus | Medium Ash - 0.6 to 1.0 % wt ash |
SENTRON™ ASHLESS 40
SENTRON™ ASHLESS 40 (0.05% wt ash) is recommended primarily for 2-stroke cycle stationary gas engines but may be used in certain 4-cycle gas engines. SENTRON™ ASHLESS 40 minimizes scavenge port, combustion chamber and spark plug deposits.
SENTRON™ CG 40
SENTRON™ CG 40 (0.93% wt ash) is a medium ash SAE 40 oil, that is specifically designed for 4-cycle stationary gas engines running in severe service, such as cogeneration, bio gas, digester and low halogen landfill or sewage gas operations. SENTRON™ CG 40 gives exceptional performance in turbocharged, lean-burn and naturally aspirated gas engines. SENTRON™ CG 40 may be suitable for use in engines equipped with certain catalytic converters. Check with your Technical Services Advisor for suitability.
SENTRON™ SP 40
SENTRON™ SP 40 (0.75% wt ash) is a premium performance stationary gas engine oil, specifically formulated for 4-cycle high BMEP stationary gas engines operating with steel pistons. This product offers significant reduction of combustion chamber deposits, outstanding top ring groove deposit control, excellent oxidation/nitration resistance and acid neutralization capability. This helps deliver a combination of extended oil life and outstanding engine durability.
SENTRON™ SP 30
SENTRON™ SP 30 (0.70% wt ash) is an advanced-performance SAE 30 mono- grade stationary gas engine oil that provides extended oil and component life in 4-cycle gas engines under varied operating conditions such as frequent start/ stops, low as well as high operating temperatures. It is formulated with wax-free, very high viscosity index base oil and advanced additive technology to provide a performance that is unattainable with conventional gas engine oils including premium performance products. SENTRON™ SP 30’s SAE 30 viscosity offers advantages over SAE 40 class oils including improved fuel efficiency, faster engine startup, and faster lubrication of critical hard to reach components such as valve guides after engine startup. SENTRON™ SP 30 is approved by MAN for M3271-2 and M3271-5 categories. Not all gas engines are designed to run with SAE 30 oils, please check with your Technical Services Advisor for suitability.
SENTRON™ VTP 10W-40 PLUS
SENTRON™ VTP 10W-40 PLUS (0.68% wt ash) is a premium quality mid ash SAE 10W-40 multi-grade natural gas engine oil specifically designed for stationary gas applications that need additional anti-wear characteristics (i.e. gasoline engines converted to natural gas) due to the valve train and/or for engines where extreme improved low temperature performance benefits are desired due to cyclic engine on-off cycles. Applications includes smaller remote well-head engines and gas line booster engines that are low emission. Not suitable for some engines with catalytic converters due to higher Zn/P Sulfur. Extended drains and excellent durability can be realized with SENTRON™ VTP 10W-40 PLUS. Check with your Technical Services Advisor for suitability.
