Using oil analysis can save you money in new oil, oil disposal and overall maintenance -- and can alert you to emerging engine problems.
The best way to know when engine oil needs to be changed is to take an oil sample, send it to a lab, and let the condition of the oil determine the interval.
Most manufacturers have yet to extend change intervals, but oil seems to thrive in the new engines.
