I do not allow my oil get dirty but I keep it filled and fresh is that bad? Due to my busy schedule I have little time to change my oil so I just keep it filled and fresh. Is that Okay?

It is not a good idea as oil does wear out and because it picks up acids and contaminants while in the engine. Those combine to form sludge and increase wear in the engine. Also, the sludge can plug the oil filter which can mean the oil runs through the bypass instead of through the filter. That also increases wear as any damaging items can just circulate through the engine.

Basically the fifteen to twenty minutes it takes to have an oil change done could save you from needing to spend two to three thousand dollars on a replacement engine, or a replacement vehicle.

Or you could DIY it anytime you want. I work two jobs and do this and that is what I do. I usually do it during my two year old son's nap time. Takes about fifteen minutes.
