Yeah! Question for Dadapedia! First of all, I'm going to assume that your husband knows how to change the oil in a vehicle. But there is no "brand" of oil-changing equipment; all that is necessary is a few tools.
1- a basic funnel like this:

2 - a drain pan similar to this (but this one is way overpriced):

3 - a filter wrench like this:

4 - a floor jack like this:

5 - a roll/box of blue shop towels or white Scott towels (these are both actually very thick paper towels)
6 - Goop or Go-Gel Orange hand cleaner (sorry, but your common anti-bacterial dish soap just won't cut it)
He'll also need a socket set and ratchet or wrench to take off the drain plug, but he probably already has that. Before you buy, peruse the garage and see what he already has. When it comes to filter wrenches, there are many types to choose from. Some work better in different vehicles depending on how hard the filter is to reach. I myself use a strap wrench. When it comes to jacks, don't fret over brands - a jack is a jack. A jack may not even be necessary but they're good to have around. I think all of this can be found at Wal-Mart, Autozone or Pep Boys. I take my old oil to AutoZone (Trinity Mills/Midway). To buy oil, a filter and a can of Berryman's ChemTool or RXP is not much less expensive that going to Jiffy Lube, but there's nothing like the satisfaction a man gets from a job well done - and you choose the products, not just take what they give you. And my garage is always spotless afterwards. Good luck!
