Designed to protect against engine wear, carbon build-up, and high fuel costs

Morey Oil says servicing vehicles with Morey’s Heavy Duty Oil Stabilizer will result in a smoother running and more efficient vehicle.
It says Morey’s Heavy Duty Oil Stabilizer reduces friction wear, keeps oil at its peak performance for longer, reduces oil burn and sludge build up, reduces heat, rejuvenates seals and reduces noise while giving cleaner bearings.
It says this is also the case with using Morey’s Upper Cylinder Lubricant (in unleaded vehicles) and Diesel Smoke Killer (in diesel vehicles) products.
Morey Oil explains these fuel conditioners help with removing the carbon build up in the fuel system, cleaning injectors, lubricating moving parts and maintaining a more efficient fuel burn.
It explains that with the fuel system running cleaner, there will be less carbon that goes into the DPF filters, prolonging its life.
For diesel vehicles Morey Oil says it is safe to use the HDOS, DSK and UCL products, with no issues with common rail or DPF units.
Morey’s Upper Cylinder Lubricant is not suitable for use in vehicles running E85 fuel.
Morey Oil HDOS, UCL and DSK are also safe to use in new or old vehicles, with Morey Oil stating these products can keep new cars ‘newer for longer’ while keeping older vehicles running.
Morey Oil says its Founder, Clinton Morey, successfully developed and marketed oil stabilizers since 1949. Since then, Morey’s Heavy Duty Oil Stabilizer has continued, even after the passing of Clinton Morey, with no formula change more than 70 years on.
