Results were proven in actual field tests: Six tractors, three fueled with Ruby Fieldmaster and three fueled with standard #2 diesel, were operated nearly continuously for 1,000 hours pulling 19,000 sleds on a dirt track. When the test was complete the tractor fueled with Ruby Fieldmaster:

• Demonstrated quicker starts
• Showed increased power and fuel economy
• Displayed no sings of abnormal wear and tear
• Ran considerable quieter
• Operated more smoothly

Ruby Fieldmaster also reduced white smoke during start up, resulting in fewer emissions and less unburned fuel. That’s a difference that translates into real savings, extended equipment life, lower maintenance costs, more work time and better fuel economy. With Ruby Fieldmaster, the proof is in the performance.
