If the 540 in a 182RG holds less than 12 qts it's an anomoly for that AC because every 540 I've dealt with has held 12.
Remember that the paralell valve O-540 in the 182 is a completely different engine that the angle valve IO-540 TIO-540 engines like those found in the Navajo. That being said, the TCDS for the O-540 engines lists a maximum Oil sump capacity for all variants of 12 qt, inclyuding the specific dash models installed in the 182. However that is just an indicatin of how much oil it can hold, the airframe manufacturer may reccomend a different amount as long as it complies with the minimum quantity. The *minimum* Oil quantity for those engines is 2-3/4 quarts

It wouldn't surprise me if the R182 O-540's had a lower oil capacity than other O-540's. In the R182, the engine was derated to 235 HP, and the oil sump pan had to be small enough to accommodate the retractible nose gear.
I suspect not. The TCDS for the O-540 lists oil sump capacity as 12 qt for all of that series engine, specifically including the J3C5D and L3C5D. I would expect that if Lycoming built an engine with a different oil pan specifically for the 182, it would have a seperate designation.

Please read the 3A13 TCDS for the 182 series

I must beg to respectfully disagree:

Here is the link to the 3A13 TCDS from faa.gov

http://www.airweb.faa.gov/Regulatory...MU61Z/3a13.pdf

This is the relevant TCDS for the Cessna 182 series, including the R182 and TR182.

The max oil capacity for these aircraft (R182 and TR182) is clearly listed on page 16 of this document and is nine quarts.

Oil capacity and other data for other 182 series aircraft are listed elsewhere throughout the document.

I also owned a R182 for a while, and I regularly fly a 182T (with the Lyc IO-540), but my answer isn't based on that, it is based on FAA approved data.

Perhaps one could physically get 12 quarts of oil in these engines, but that is contrary to the aircraft manufacturer's FAA approved instructions and not necessarily a smart thing to do anyway.

I realize there are many more important things in the world, but the question was asked and since there is an answer based on official FAA approved data, I think that's the answer that should be given.

If you have FAA data that says the max oil capacity of the engines installed in these aircraft is indeed 12 quarts, would you please post it?

Like I said previously, the information I gave is straight out of the FAA TYPE CERTIFICATE DATA SHEETS which you, yourself have proposed as the definitive source for "official FAA approved data," That *IS* the answer I have given. The TCDSs I quoted are for O-540 and the O-470, specifically, the 12 quart figure for the J3C5D and L3C5D is in TCDS E-295, page 3.

Like I said previously (I really hate repeating myself for the benefit of people who can't or won't read) the 12 quarts is a *MAXIMUM* possible capacity, not a *recommended* service quantity, the *recomended* service quantity would come from the airframe manufacturer.

Now, If you believe that the the airframe manufacturer's reccomemdations invalidate the engine manufacturer's data, I respectfully suggest you address your concerns to Textron Lycoming and the FAA.

Here is the relevant data excerpted from the TCDS for the R182. THe aircraft TCDS is where POH data comes from, and is the FAA approved data for operation of the aircraft.

You may wish to advise young pilots to follow the engine TCDS rather than the FAA approved POH procedures (which are derived from the aircraft TCDS). In general, I'd recommend against deviating from the POH and the data it's derived from. Your mileage may vary.
I do regret getting you all cranky & stuff over this - do try to have a nice day[/FONT]

Look JCJ,

Would you go back and read my posts. It is painfully obvious that you have not, at least not to any meaningful level of comprehension.
Now, can you find *ANYPLACE* where I said that someone should ignore the POH and fill a 182 lyc. engine with 12 quarts of oil? Anywhere at all?

Right, No, I didn't.

I brought up the 12 quarts primarily as response to icefr8dog's comments, which were somwhat of an aside. If you had read my posts for comprehension, you would have noticed that nowhere did I say that the TCDS for the 182 was incorrect, in fact I noted that it was different, and commented on how the difference might come to be. If you had read my post at all, you would have noticed that I also mentioned the *minimum* oil quantity listed on the TCDS, but that is not to be construed as me recommending that somone depart with only 2-3/4 quarts in the sump. And thank you for posting the 182 TCDS, but I *have* read it, and I *do* know what it said .... before I made my first post on this subject.

Tell you what, if you respond, why don't you resopnd for a change to something I actually said, instead of responding to things you merely imagined I said, and going off on some sanctimonius tirade about following the POH?

Deal?

No, I'm not cranky, I just have an extremely low tolerence for people blindly contradicting without understanding what has actually been said.
 
C-182

Thanks for all the answers,I never flew the 182rg,I was very lucky to fly the 182,my memory was 12 qrts and a heated debate elsewhere made me check my memory.I think the dipstick we had on the old 182 was non original and there were scratches for numbers.The old 182 kept me and many others safe since 1957 (me thinx)...

Mmmmmm, impressive, you've resorted to name calling, if indirectly. I think that most consider arguing ad hominem to be a farly reliable sign that someone has nothing of substance to say on a subject.
