I just stopped bothering when it got harder to access the filter/drain and I moved to the city where I park on the street. I'm much less interested in farting around under the car, getting messy, and spending a half hour or more to drain the oil, replace the filter, and refill.

At some point I just decided it was worth the extra cost to be in and out quickly. And honestly, when you add up the cost of replacement filter and oil, the premium isn't terrible when you add in time saved. I like knowing how to do it, but it's been several years since I bothered.

Top-side filters and oil extraction pumps make oil changes almost effortless. The biggest problem for me is disposing of the oil. There are several vehicles in my family, and the old oil just collects in jugs by the garage door. The nearest hazardous waste centre at the landfill will only accept two jugs at a time, and they won't take 5 gallon buckets at all. They will not accept 10 jugs (<2 years' worth), let alone 30. It's like they want me to pour it down the drain or something!

Often parts stored like AutoZone, O'Reilly's etc accept waste oil.

This. I had a similar situation to the GP poster-- years of used oil piled up in jugs in the garage. One trip to a local parts store and the issue was resolved. It was shockingly easy.
