Engine applications using landfill gas is the biggest challenge every petroleum manufacturer faces. The specific conditions of these engines push the required oil quality and performance to the limit. To stabilize high concentrations of acid, an oil with a higher ash content is required. The extensive reaction of overbased cleaners and acids can lead to increased deposit formation and an increased risk of undesired varnishing of the lining.

Cleaner engine with less fuel consumption

HDM engine oil. Thanks to its unique technology, the deposits remain in the oil, avoiding varnishing and limiting oil consumption.

In New Zealand we tested HDM engine oils against an OEM-approved brand A competitor. Subject of study: INNIO Jenbacher 320GS gas engine. The customer tested the Q8 Mahler G8 for 7.000 hours continuously in their landfill and compared the results with their conventional A brand motor oil. The results are shocking:

• Increased oil change interval by 200 hours.
• Fuel consumption reduced by 40%.
• Inspections show reduced deposits and improved engine cleanliness.
• Deposits are very soft compared to deposits formed by competitor gas engine oils.
• The liner used to be covered from bottom to top, whereas the HDM only showed up slightly on the upper end of the liner.
