labor rate, oil analysis cost and how they are affected when the
inter val is changed.
There is always a risk associated when extending these service
intervals. This risk can be mitigated somewhat with careful planning
and a solid oil analysis program. Extending intervals can provide great
opportunities for maintenance cost savings as long as it is done care-
fully and based on sound data.
One of the most popular interval extensions is the oil drain. Below
are some guidelines for extending an oil drain based on oil analysis.
• Set water maximum to 0.2 percent by volume.
• Viscosity is within 10 percent of the baseline.
• Fuel dilution should be a maximum of 2 percent.
• Soot levels are 25 percent below the manufacturer's maximum
recommendation.
• The base number should not fall below 50 percent of new.
• The acid number should not increase 1.5 percent above new.
