I Don't know who is actually doing the assembly of the filters. Donaldson design.
The local owner of the store is probably a independant dealer and is not part of either NAPA's or True Value's corporate inventory structure.quote:

Amen, Patman. I've been favoring the M1 EP (oil & filters) regimen to avoid the mid-year filter change...but now I might give Amsoil a second look (after I use up my current stash of coursequote:

So if this filter is good for 25k, does that mean Amsoil will no longer recommend changing the oil filter every 6 months? That would save a lot of time for people if they could run both the oil and the filter for one year/25k. A lot of people already run their oil filters for one full year anyhow, but having this new filter will give them added peace of mind. It sounds like a good product, their SDF line is already extremely good, so I'm sure these will be even better.
Probably not. I'm going strictly for the convenience factor these days. Especially on my Chevy where the filter has been nicely placed to drip oil all over some electrical crap, my arm, you name it.quote:

A one year filter change sounds good but does a better filter help to prevent sludge, control the TBN and keep the engine cleaner then a lesser filter changed twice a year?
And if you read my thread on the "life" test of the E-core filter I used after near 7000 miles..it would have lasted 4-5-6 times longer as well.quote:

Now, if you have a bad engine and the oil shows sludging on the dipstick, it would be prudent to have the oil checked.
There has been research that shows that the smaller the particles in your oil the less wear in your engine. However, other things affect wear too, oil weight, additives, etc. So, the question is whether you engine will wear out because of particles or something else. Still, smaller is better. Less bypass is better too.quote:
Where's the research saying particles of these size ranges cause the majority of wear/problems and what filters are specifically engineered to remove these particle sizes? I can't believe that smaller is better after a point!!
