I would not do anything special until you determine the engine actually has sludge. Pull a valve cover.

The thing with her car, however, is that she does primarily short runs of anywhere from 10 to 15 minutes of driving, to and from work, and occasionally maybe about 45 to 50 minutes on the highway once a week or once every two weeks. But primarily her driving consists of no more than 10 to 15 minutes at a time. I am assuming that because of the short drives, her oil is not getting to a high enough temperature to burn off any condensation, and that this potentially could be a contributor to sludge buildup. She only drives about 5,000 to 6,000km a year, and I change her oil every 5,000 kilometres which means I usually change it every 10 to 12 months. And this is why I'm using Dino oil instead of synthetic. Although there are no problems associated with the oil I'm using as far as performance, sound, or anything like that, I am wondering if there is specific type of oil that I should be looking at, or one with a specific additive package that is better suited for short-haul trips where the oil does not make it up to full temperature most of the time?
