I do not know by pass psi rating but can is rated for 500 psi burst .
is a bigger filter and gives no oil pressure fluctuations like some
other automotive filters i.e. bypass sticking or to high or low psi
setting, price is the same as the rotax filter its just available
locally. bob

Your comment is well taken, however, you and Roger Lee seem to be on
opposite sides of the fence on the matter of using automotive oil
filters for the Rotax 912 UL. Check the Archive for this subject on this
forum or drop him a note directly. The date of his comments is 12/29/06
on the Rotax engine forum. In his comments he states that the Purolator
1, PL10241 has a bypass rating of 12 psi. I do not know what the by-pass
relief valve setting in psi is on the Rotax filter. Can you shed more
light on this for all of us?

Jack,
It's a serious No-No. You do NOT EVER want to use an automotive oil
filter in the Rotax engine. The issue isn't filtration but pressure
relief valve setting. Automotive filters have a much lower pressure
relief valve which will allow dirty oil back into the engine before
filter change time. Resulting damage will make a real Rotax oil filter
seem dirt cheap.
Good building and great flying,
Bob Borger

Thanks again Ellery. Advice well worth paid for (I did contribute to the list
fundraiser this month). You made me wonder about the markings and so I went back
and re-read my email from the DAR and he only mentions the red mark on the
CHT. Although it is GOOD for me to know what is a good and valid range for when
I finally get to fly my little plane.
Thanks! :D

Hi All,
I just typed a nice long explanation on filters and this website timed me out and
I lost it all. When I calm down I may retype it. In the mean time look at:
http://motorcycleinfo.calsci.com/filters.html
There is some misinformation on some of the post. Just hearsay and no sound research.
I think we can put all that in persprective.
I'll be back. I think this time I'll type it under Word and attach it. This is
the second time this site dumped my work.

Hugh,
I've gone through my notes from the Lockwood school and I did not
make note of the bypass pressure of the Rotax oil filter. I have
sent an e-mail off to Dean Vogel, the fellow who teaches the school.
I'll let you know the results of any reply.
If you are interested in what is taught at the school, I have a photo
album of the shcool on my build web site. I highly recommend the
school to anyone who owns a Rotax 9xx engine.
Good building and great flying,

Bob:
I must disagree with you on the price of the Rotax Filter and the Purolator
1 PL10241 Filter. By the time I get the Rotax filter from Lockwood Aviation
with normal shipping the bill to my credit card is $31.33. This is
outrageous! The Purolator 1 is only $5.88, and the store is right around the
corner. I have not used the Purolator filter yet and am getting conflicting
information about the two filters. I am trying to find out the real
differences in the two filters to justify$31.33 vs. $5.88. Cane anyone else
add to this discussion?

Hugh,
I too took the line maintenance class with Dean Vogel.
The information from the class was definitely in favor of the
"official" rotax filter. Dean was also quite clear on the great
sensitivity of the Rotax engine to clean, adequate oil.
You are free to make your own choice of course, but you do own
an aircraft, and know the consequences to your wallet!
Cheers,
Ira

Hi Guys,
Just a quick note before bedtime. The Rotax bypass pressure is .9-1.1 bar or 13-15.9
psi. The people who teach the class which I have attended are only repeating
what they have been told. Research is better than hand me down info. I will
post tomorrow on this. Please read the website I posted it will help understand
oil filters better. The USA filters in my post are at 12-15 psi. This is
not worth worrying about and I will explain tomorrow.
When I researched this subject I can't begin to tell you how people, in the business,
interpreted bypass pressure.
P.S.
There is no risk and the other filters have been proven with more than 10 or more
years experience in the field with some 912's with 3K+ hours and no rebuild.
Good Night and safe Flying.

Bob, I did take time to view all 145 pics in your Lockwood school album
very interesting and an excellent job with the camera. One thing that
sort of raised the hair on the back of my neck was the fact that a
statement made as to the removal, disassembly, cleaning and
reinstallation of that oil tank. Unless I missed it I checked ROAN's SB
and SL as well as the line maintenance manual and no where could I find
that task, can you shed some light on that?
