EAO44 is the oversized filter, same as SDF44 for those TL/CL owners who use them.

I just did my oil change and I'm out of filters and oil so I'll probably order a few in a few months. Anyone try them yet? Looks like the SDF44 is no longer available.

This is good news,, a better filter,, my next change I'll use one of these for 10 k miles and then do a analysis. Right now I change filters every 5k,, these are 25k 1 year filters,,, seem to be a lot better filter but I don't know of any analysis that has torn them apart and compared the materials.

One member on Bobistheoilguy has purchased a EaO-15 and is in the process of getting some pictures up. The filter appears to be of a Donaldson design, but doesn't have that much media, 179sq ft, IIRC. But don't get carried away, they may be using a different approach here.

As for the oversized filter, I'd instead stick with stock sized, SDF 20 instead of using an oversize. In addition, I'd use the less expensive, still excellent, Wix Oil Filters that you can order from Filter1.com over the Amsoil filters at more frequent change intervals. Run Amsoil "ASL" 5w-30 at a 1-yr/15K drain interval with a filter change and top-off at 6mo/7500 miles. Do an oil analysis ($18) after the first drain to verify the drain interval. This setup should save you more $$$ over the XL 5w-20 you're using at 7500 mi. intervals.

The Wix 51334 is the stock sized filter and can be had from filter1 at $4.22 a piece. ASL 5w-30 can be had for $6/qt shipped, by the case.

Calculations:
XL 5w-20
$5*5=$25+$10=$35
$35*4=$140 for 30,000 miles

ASL 5w-30
$6*6+$5*2=$46
$46*2=$92
$18 for oil analysis + $92=$110

$110 vs. $140= about a 20% savings.
