IMPRESSIVE DRAIN TIMES IN NEW GAS ENGINE OIL

A new engine oil for natural and biogas engines has proven to achieve drain intervals of more than 1,500 hours, increasing productivity and reducing downtime costs.

Morris Lubricants’ Geo Ultra S40 has recorded the impressive drain times while running biogas and Natural gas fuelled MWM engines. 

This is made all the more impressive as Hydrogen Sulphide levels are high in the machines – often greater than 300ppm - from digesters running on Maize, broiler muck, Sugar Beet, Rye Grass, Triticale and potatoes, whilst still maintaining a low ash formulation.

In natural gas engines, drain times have also been extended, particularly in smaller sumps associated with MWM engines. These sumps can be as small as 100 litres – or less – and are therefore prone to oxidation rather than TBN depletion. Geo Ultra has already achieved drain intervals of 1,000 hours – and counting.

Morris Lubricants’ technical services manager Simon Matthews said: “Geo Ultra S40 has already produced some impressive results with drain times in excess of 1,500 hours.

“It means the machines can run for longer periods before changing the oil, reducing costs and increasing productivity. 

“The low ash formulation of the Geo Ultra S40 has also proven itself to leave valves and pistons free from deposits, which can be a particular problem in gas engines.”

Geo Ultra S40 is currently pending formal approval for MWM engines.

Morris Lubricants, one of the county’s leading oil blenders, is making in-roads into the rapidly emerging global gas engine market. 

Experts at the Shrewsbury blender have been working to create highly sophisticated oils to work in engines that use gas extracted from a variety of sources, including wood, sewage, landfill, farm waste, slurries and unwanted harvest.

Morris Lubricants now has a range of products with MWM and Jenbacher approvals, while trials are ongoing in Guascor and MAN engines.

Gas engines are used in a wide range of power generation applications, ranging from hospitals to industry where reliability and continuous operation are paramount.
