Most engine mfr’s mx programs recommend oil changes at 50 hrs…and filter changes at 100. It’s just that most of us do both at the same time…(and anal mx people like myself do both at 25 hrs…just like we did before spin-on oil filters became available for aircraft.).
To avoid shipping costs…..I always bought aircraft filters by the case-load so haven’t experienced the reported shortage …yet! …. but it may become more common for folks to follow more closely the mfr’s recommendations if shortages continue…. 50 hr oil changes and 100 hr filter changes.
If matters continue…. I’ll even consider removing the filter adaptor and returning to the OEM oil-screen use. (Continental O-300 user)
I suggest looking on eBay. Sometimes you can get the OEM filter kits at a little bit of savings. I usually look for free shipping, and may not have to pay tax depending on state you live in...
Be careful on eBay. There are many counterfeit items of all types on there.

My Lycoming is a 50 hour oil and filter cycle... The Continental doesn't have a recommended cycle because it was built before screw-on oil filters were invented! After adding a filter adapter to that engine I've opted to follow the same 50 hour oil and filter cycle as the Lycoming-powered airplane. A camshaft or crankshaft for this engine is "unobtainium" so changing oil is cheap prevention.
And speaking of changing oil, just received updated pricing on my engine oil of choice. Case price has gone from $98 to $148. Ouch.

I have a case or two of Phillips X/C 20W-50 aviation oil, left over from my Twin Comanche that I sold years ago. I do not know what to do with this oil.
I have been told that it contains no detergents,(ashless dispersant) and is thus not suitable for my 21HP Kawasaki powered Scag mower.
I do not quite understand why it is suitable for one 4 stroke air cooled engine, but not for another.

I’m not looking for a pizzing contest but…. I also don’t know which particular “contenental engine” you are discussing that was “built before screw on filters were invented”…. so we’re not being sufficiently specific to be accurate in our statements.
The aviation oils do not contain “detergents” because ”detergents” often result in metallic residues which can cause detonation at altitude. Most Aviation oils contain “dispersants” which keeps dirt suspended until it can be drained or filtered out. Phillips XC 20W40 is such an oil and would work just fine in your air cooled engines.

I had a 40 year old supply of Mobil “Red Label”…which is/was an obsolete aviation oil…that I was reluctant to just throw away. So I used it for 15 years in my Ford 9N with excellent results.

I e-mailed Phillips, and they suggested...NO!
Confused!
Are you aware that the oil flows from the OUTSIDE to the INSIDE of an oil-filter? (There is more surface-area on the outside to capture debris)
The filter-media is physically supported by the perforated metal tube INSIDE of it as the flow pushes towards the inside.
Hence: There is little chance of the media 'ballooning inside the canister'
So the little girl running the computer when you sent the email gave you a “no”…and that must be expert advice…. ? They also don’t recommend it for door hinges. I’ll give you a shipping address and I’ll dispose of it for you so it won’t pollute the landfill near you. (wink)
keep griping about airplane maintenance costs. Or just go buy an electric one. Problem solved. Right? Environmentally responsible thing to do isn't it?
these people who have the idea to attack oil/gas are apparently ignorant of the many implications. Their political agenda is bankrupting Americans and has been for years

Why didn’t we just go take our oil after 9 1 1 and put an end to this B.S… Don’t know why we let this continue… GWB let them all get on their jets and go home while WE all had to SIT HERE on the ground! ..and then we go an blow a ton of national-treasure and American lives on their next-door neighbors who had nothing to do with it.
that "we" know of
My brother was all up in that mess. There is a LOT more to it than the general public knows and that is all I am going to say.
Just to clarify 'cause I'm a little confused ... which oil was "our oil"?
the oil which ”we” discovered and developed the fields.
Yes, there IS a lot more to it, especially after “citizens united” which allows certain “monarchs” to contribute endless amounts of money to political campaigns anonymously. Figure out which politicians are in bed with big oil companies and you’ll have the answer to why some people can be murdered by monarchs and nothing happen over it and why thousands of American boys are dead and why we spent thrice the time fighting over there than in WW2 and why high gas prices are rampant to punish certain administrations than others.

It actually was not a "little girl" that responded, but a guy from the Phillips tech dept. who might be an "expert".
Still,.....I don't understand what the sea level oil type difference could possibly be, between an air cooled aircraft engine, and a air cooled mower engine, using the X/C oil.
Perhaps Phillips does not understand that the 21HP Kawasaki has an oil filter?
I think he gave you their “legal dept” standard answer. He has no idea what condition your engine is in…and if you used their oil with their blessing and your engine ever fails they’re worried you might sue them. They can say “no”…with no penalty. They only take-on liability if they say “yes”..)
I ran my 9N Ford on old aviation oil for 15 years, and I run my air-cooled B&S, Wisconsin, and Robin engines on it just fine. (also a couple Chondas.)
If you’re sittin’ on 2-cases of XC oil … then there’s guys at your local airport who will see it as $150 worth of oil.

You explained why aviation oil, containing dispersants rather than detergents, is advantageous in an aircraft engine, because it doesn't result in metallic residues.I’m not looking for a pizzing contest but….

Do you know what the advantages (if any) are of detergents? Are they simply cheaper or do they have some performance advantage within the operational envelope of a non-aviation engine?
