In the December 2008 issue of Road and Track, on page 73, there was an ad by Valvoline. It stated that there Synpower full synthetic oil is 4 times better that Mobil 1. Any comments?

I disagree with your assumption that all oil filters will perform equally.
The dirt holding capacity may not be much of a factor, if you are on a 3000 mile drain interval, but the quality of construction, the performance of the anti-drainback valve, and the amount of time the filter is in the by-pass mode (like on cold starts), are not necessarily going to be the same across the brands.

I seen the ad in other media. Walmart has it for $19.00 for a 5 qt jug, which is cheaper than Mobil 1.

the maintenace and repair forum has a lot of info on oil quaulity that is worth reading. cost is not always a good measure of quaulity. mobil 1 is a proven performer. check out the other forum if you haven't yet it is way over my head but still has a lot of good info.
