I received a "spring flyer" for some of Aircraft Tool Supply's  offerings.

One item that caught my eye was Champion Oil Filters...pretty standard units ... Aircraft Spruce lits them for $16.25 in my 2005 catalog, but ATS is offering them for the

"Retail Price" of $33.90, but offering 20% reduction, so you can get all you need for only $27.46 each.



Wow! what a deal !!

FWIW, I switched from Champion CH48110-1 to Kelly Aerospace ES48110 oil 

filters and have been using them exclusively for a few hundred hours now --  

and I plan to keep using them.  $12.65/ea from Spruce.  Saving a few bucks. 

I did a photographic comparison of the Champion vs. Kelly oil filter 

element.  There are physical differences, particularly fewer pleats on the 

Kelly.  But nothing (imho) that's significant.  I'm a cheapskate wherever I 

don't feel there is a safety risk.

Spruce used to sell another even cheaper oil filter, maybe Challenger?  I 

forget the name.  It was like another 2 bucks cheaper than the Kelly.  I 

figured...baby steps.

Dan,

 You might want to reconsider that move. In 2004, Aviation Consumer did a comparison of the Champion and Kelly oil filters (Volume XXXIV Number 9).  The Kelly has 20% less filtering area. Bottom line was they recommend spending the extra money for the Champion.  I can email you a scan of the article if you like.

Charlie,



That's in line with what I photographed.  Less filtering area.  I don't 

personally think it's all that critical for a plane that is flown regularly, 

oil changed every 25 tach, oil+filter changed every 50 tach.  I'm not trying 

to convince anybody of anything, like to use Kelly over Champion, just 

saying that I use Kelly to save a coupla bucks and don't believe I'm taking 

a measurable risk.

  It's your engine and airplane. I could understand saving on the 

Kelly filter, if you were changing the oil and filter every 25 hours. 

Changing the filter that often, I doubt that a 20% reduction in 

filter area would make any difference. The problem with clogging a 

filter, is that the bypass valve in the filter then opens. Once that 

happens, the filter is effectively gone. The oil moves through the 

system unfiltered.

  I see the same thing with auto manufacturers who specify full 

synthetic motor oil and 10,000 mile oil changes. The oil can go that 

distance. Often, however, the filter will clog much sooner. The 

benefit of using a superior oil is lost, if it's not being filtered 

the last 3-5 thousand miles of each oil change interval. I recommend 

that folks who use synthetic oil/long drain periods, change out the 

oil filter mid way through the extended drain period.

  50 hours means 50 X 160 mph = 8000 miles. That's a long way to go 

without changing the oil filter.

I don't necessarily disagree with you.  But lemme put it this way -- if it 

gets so bad that the filter bypass is in use, 20% more filter area ain't 

gonna do diddly...I would have MUCH BIGGER problems than just that!



I appreciate your concern, though.

Guys,



I use Napa Gold 1068 filters, or Wix 51068.  $5.96 at the local Napa.  No

safety nut but who cares, if you torque it down it isn't going to come off

in flight.  A few RV's in my area fly with these filters with no problems.

I can't remember exactly what the burst pressure on these filters is but its

somewhere in the 400 psi neighborhood.  My oil analyses have come back good

with less than average metal content for an O-360.  A big advantage of this

filter is that it has an anti-drainback valve, which keeps oil in the filter

when the engine is shut down so that the top end quickly gets oil during

start-up.  When I cut these filters for inspection, I have measured 1/2 qt.

of oil out of them even after standing it up on its end.  Why pay $18 for a

filter design that is 40 years old.



Regards,

Bob Japundza

Hi Charlie



Educate me, - is filter clogging on a good engine something to actully 

consider?  I change filters at 50 hours and cut them open for inspection 

and have observed that a good engine could probably go 10 or 20 times 

longer before there would be any significant amount of contaminate 

material to restrict flow through the oil filter pleats (high time 0-470 

would block maybe 3% of pleats with carbon). I am also assuming that 

when filter pleats are slowly clogging with microscopic size material 

the filtering capability would actually increase up to the point where 

the bypass valve opens. If the bypass is spring loaded it will crack 

open as a function of pressure and only some oil will bypass while much 

of it would still pass through the filter pleats up to the point where 

they become fully clogged. What am I missing here??

George,

  If you are finding very little material in your filter, than by all 

means use it up to 50 hours. One thing to bear in mind though. When 

you loosen the filter, almost all the oil and most of the foreign 

debris drain out of the filter, so your inspection may or may not be 

accurate, regarding how much material was actually in the filter. I 

suspect that aircraft oil filters do not have the ability to filter 

down to 25 microns like automotive filters do. With the larger 

clearances on our engines, super fine filtration is not as critical. 

If the filter doesn't have to stop these smaller particles, it will 

obviously take longer to clog.

  Clogging is a relative term. The back pressure of the oil 

(especially if you use straight weight oil and the oil is cold, such 

as on initial start up) will open the bypass valve at much less than 

fully clogged. At what percentage point this would occur, I don't 

know. Is Doug Rosendahl still on this list? Doug is a petroleum 

engineer and could answer these questions better.

  If the bypass valve opens, a great deal of the oil will pass 

through unfiltered. Path of least resistance, ya know.

Charlie
