Hmm.. Lowest I have seen those Jugs is $17.88. This includes a number of Walmarts in Pa, Va, and FL. I have found that they are most often available in the spring, but my Walmart has them now too. I have 3 of them now. I have 2 or 3 Mobil 1 filters around too because I found them on sale somewhere.
I have only ever used Mobil1 in my current car (bought new) since the first change at about 1500 miles. At about 10,000 miles, I began to also use Mobil1 filters. I have been pleased with their filters and notice a difference in the oil when I change it. I change my oil with Mobil1 and the M1 filter about every 4,000 miles. They say you can go longer, but I drive pretty hard, and like to have fresh oil in the car.
As for the benefits of synthetic... if you plan to keep your car for a long time, I would reccomend them. I noticed a drop in the operating temp, and they say you get about 3% better gas mileage too. Not to mention the improved friction reduction etc.
As far as filter quality... some of the OEM/regular filters scored well in those "take apart" studies. AC Delco (OEM for my car) got a good review. FRAM totally sucks and get ripped on by anyone who knows about oil filters. You get what you pay for...
I also would not trust Walmart without watching what they are doing. I would not let them do it while I shopped. I have heard stories about many of these places "redlining" cars, and generally not being say professional. For this reason, when I bought a new car last summer, I decided to start doing my own oil changes, as well as other routine maintenance things like changing the Fuel Filter etc..
