These stationary gas engine oils are premium performance engine oils with between 0.6% and 1.0% weight ash content, designed for applications requiring medium ash levels while providing outstanding anti-wear protection and reduced carbon build-up.

Products under this include

• SENTRON™ CG 40 is a mid-ash (0.93 wt%) SAE 40 stationary gas engine oil specifically designed for 4- stroke gas engines running under severe acidic conditions such as sewage or sour gas or low halogen landfill gas operations.
• SENTRON VTP 10W-40 PLUS is a mid-ash (0.68 wt%) SAE 10W-40 stationary gas engine oil specifically designed to aid diesel- and gasoline- fueled engines that have been converted to natural gas and need additional anti-wear characteristics due to the valve train, and/or engines where extreme improved low temperature performance benefits are desired due to cyclic engine on-off cycles.
• SENTRON SP 40 is a mid-ash (0.75 wt%) SAE 40 stationary gas engine oil specially formulated for high performance - gas engines operating with steel pistons.

• Outstanding anti-wear protection prevents scoring of cylinder liners and piston ring wear, while reducing carbon build-up

Suitable for 4-stroke cycle gas engines requiring a Mid Ash product with either traditional or non-traditional gas sources
