Oil Filter Recs

_{Amsoil filters are made by Champion labs.  No need to pay the mark up for the Amsoil name (sorry, dealers) when you can go buy a great quality filter for much cheaper.  Just get a Champion brand.}

I wonder if the champion labs filters are made to the same specs as the Amsoil filters.  Just because they are made by the same people doesn't necessarily mean they are made the same.

Various manufactures make AMSOIL's filters.  Nobody knows exactly who does but AMSOIL and they will not disclose who does. 

 

The Ea0 filter is specifically made to AMSOIL's specification by a filter manufacture.  It is not the same as the run of the mile Champion labs or any other manufacture's filter.

Changed the oil on my 18 yesterday.  This was it's first oil change.  I decided to change it at 1300 miles on the clock just to make sure there was no assembly or break in gunk in it.  It had the PF63 on it from the factory.  The engineers may have changed the spec, but they didn't seem worried about it enough to make the engine factory change what they install. Is it possible we are making a bigger deal out of the bypass valve rating than the engineers did?

 

Anyway, it got fresh Amsoil 0w-20 signature series and a new EaO17 filter.  

 

I was a bit surprised at how thick the oil that came out seemed.  The engine was only slightly warm but what came out was definitely thicker than what I put in.  Is it possible that it had 5w-30 in it?

Manufactures do 'running changes' all the time. They change a spec and continue to use the old stock until depleted. 

 

Viscosity is a function of temperature. There is considerable difference between 'full operating temperature', and 'slightly warm'.

 

More than you might think anyway. Spec wise 5w20 and 30 W at 212 F (100 C) are but 3 CSt apart.  At 104F (40C) about 18 CSt. 

 

   9.0 CSt @ 212 F / 53 CSt @ 104 F for 5 W 20 (Red Line HP) 

11.9 CSt @ 212 F / 71 CSt @ 104 F for 5 W 30 (Red Line HP)

 

Take note oil heads that in this example there is a 34% difference in viscosity at 104F between 5W designations in their respective grades.

Grumpy, I have no way to actually measure viscosity.  My point was that the oil that came out was only slightly warmer (10-15 deg) than the new oil I out in.  The old oil seemed thicker than the new.  Just seemed curious to me and I was wondering if it was possible that they used a heavier oil at the factory.

 

My point on the old part number filter was just that it seems they would forego using up old stock if it was really a big deal to them.  Nothing more.
