Regrettably, engine oil will gradually oxidised and form acids as it interacts with moisture and combustion byproducts. These "dissolved" contaminants cannot be rid of unless you perform a drain-and-fill (with fresh new lubricant of course).
At the end of the day: would you rather keep your that rancid, contaminated oil inside your engine up to 30,000miles?
I personally would not buy it (and will not do so in practice either).

Will extending the drain intervals and using the oil up to 30,000 miles have a negative effect on the additive package in the oil?
A: The additive package in engine oil is intended primarily to suspend particles in the oil. Additives are also present to reduce oxidation and changes to viscosity. The microGreen filter is unique in that it captures the small particles down to 2 microns in size. These small particles are not removed by a conventional filter and, therefore, deplete the additive package and lead to chemical changes in the oil. By keeping the oil clean the microGreen filter ensures that the additive package is not consumed in as little as 3,000 miles but remains active in the oil up to 30,000 miles. The following are a few key points based on extensive research:
Extensive on-road testing and oil analysis clearly indicate that using the microGreen oil filter, even after 30,000 miles does not adversely effect the viscosity, wear metals, and oxidation (TAN/TBN) levels in the oil. All of these measures remain within normal operating conditions throughout the extended oil life. Clearly, these levels cannot be maintained if the additives can been depleted.
Research has shown that heavy-duty trucks, using By-Pass filters, allow these vehicles to extend their drains intervals without affecting the additive packages. The microGreen filter works in a similar manner to by-pass filters by utilizing a secondary high efficiency filter to remove small particles from the oil.
Up until the introduction of the microGreen filter, research was not possible on extended drain intervals for light-duty vehicles based on improvement in filtration efficiency down to 2 microns. That is because a filter did not exist for these vehicles that could significantly filter out these small particles from the oil.
Additionally, the chemical analyses of the oil using the microGreen filter also indicates that the microGreen filter ONLY captures the small contaminant particles – it DOES NOT filter any of the additive package
