It's not about the filters, if we installed ten or more filters along side the frame rail it will not help, it's about what's not in todays newer oils out there that's the problem.
 


Nope, not good at all!
The filters (I would assume) won't do anything after the first one filters out all the bad stuff, unless that one is all full of bad stuff.

I think you can't beat AMSOIL, their stuff isn't made to anybodies specs, and their commitment to quality seems to be top-notch.

I hear so many here saying they use Rotella.  Which Rotella?  Rotella is the name Shell has attached to their motor oils. I checked their web page and they have several different versions of Rotella.
 
As for filter, some are better than others. I've seen them disassembled. Some have much more media than others. Some have better anti-drainback valves.  I prefer the coil spring types of pressure relief. I just think they'd be more reliable. Some filter to 40 microns. Some filter down to 10 microns. The three I mentioned above filter down to 10 microns. I guess if "meets OEM specs" is good enough for you, then it's a good enough filter for you.
 
Edit add: As far as oil additives are concerned, the synthetic oil manufacturers I've looked at all warn somewhat sternly to "not ad any additives."  If you are going to use a synthetic with zinc, buy a synthetic with zinc already in the additive package.

For me, I use what is now called Rotella T4. It used to be simply Rotella T.

T1- straight weight conventional
T4- multiweight conventional
T5- synthetic blend
T5- synthetic blend, newer vehicles
T6- full synthetic
T6- ultra, newer vehicles.

None of which are the "old oil", I presume.  I bet T2 and T3 fit the bill, but they discontinued it because it had too much of this or too much of that in it.
 
I'd like to see the 4-ball test done on something like T4 with zinc and compared to T6 without zinc. For older engines that would give me some indication of tappet wear.  I bet the T6 would perform well.
 
 
BTW, synthetic blend with 10% synthetic and 90% mineral oil does not impress me in the least.  Usually that's the ratio.  It's marketing schlock.
