Q8 Oils

Gas Engines

There is an increasing number of high efficiency engines on the market. Gas engines in particular are subjected to extreme operating conditions, especially around the combustion chamber. This results insignificant technical challenges for lubricant manufacturers, particularly in terms of oxidation control and deposit control with outstanding Total Base Number (TBN) retention.

Q8 Mahler is a range of high quality lubricants for engines using all types of gas, including natural gas (bio, landfill, sewage and other highly polluted gases) and automotive gas engines.

These oils offer outstanding benefits:

  • high oxidation and nitration resistance for long service life
  • low ash deposit tendency and good resistance against pre-ignition
  • excellent anti wear properties to protect the engine against valve seat recession
  • high acid neutralising capacities as a result of high TBN retention


Operating conditions vary substantially and Q8Oils can provide advice on the best oil for your application. You can also benefit from Q8Oils’ Analysis Programme to help you achieve the best productivity and reliability.



What our customers say about Q8 Mahler


 “We have been using a range of Q8Oils products on our engines - Deutz/Caterpillar/Jenbacher - for nearly seven years and can fully recommend Q8 Mahler. It has achieved a longer than expected oil life accompanied by reduced combustion chamber deposits and minimal linerlacquering, resulting in extended liner and cylinder head life. As with all engines running on landfill gas, these benefits are of great importance for both the smooth running and reduction in operating costs. Equally important is the customer support and technical backup that Q8Oils provides. We have worked closely with the Technical Team over the years to the benefit of both parties, especially with respect to the oil analysis techniques and the trialing of new products.”
