I was at Wally World this afternoon and as usual found myself browsing around the automotive section (even though I really didn't need any automotive products). While there, I took a look and did a visual comparo between the Motorcraft FL820 and Supertech equiv. The Motorcraft is a good 1/2" deeper so I guess would hold more and thus flow more oil. Is that a good assumption? Also, the 6 holes at the front screen are rather smallish and round on the Supertech but elongated and a bit larger on the Motorcraft. Would this also allow for greater flow? Looking at the interior screen of both showed the opposite though...the Motorcraft's screen holes were smaller than the Supertech. Anyone have flow specs on these two filters? I've been using the Motorcraft filter as of late but am looking to get a good balance between flow rate and filtrtation. If there is a filter that flows as well as a Fram but filter efficiently down to 15 microns that is the ticket. Also noticed (never bothered looking before) that they have full synthetic Supertech 5w-30 for $1.76 / quart . I asked the Wally World associate that was stocking fresh supplies of M1 and e said the Supertech oils are manufactured for them by Quaker State. Anyone know if this is in fact true? I almost purchased a quart just to send in for a virgin oil analysis to see what it looks like. FWIW, the Supertech dino 5w-30 is .84 cents / quart and according to the guy is basically Quaker State dino in a different container.
