Damage list
Engine oil
Radiator
Engine
(etc)


Either you've had one to many or one not enough.

As said, Engine Oil is first on the damage list for every plane.

:huh  Engine Oil is already in the current damage list

no....*sarcasm* the red indicates it was hit, if the engine got hit then it would lock up right away, im saying is as soon as the last drop of oil is burned your engine automatically shuts off, i would rather run it and burn it up than shut it off, read the previous posts before you make one

Ok, I think you need to learn some engine mechanics before posting about engines and oil. When an engine runs out of oil, the motor ceases to operate properly thus it seizes up and shuts down making it impossible to burn up. The only way to possibly burn up the engine is if you have an engine fire due to some very bad circumstances such as the oil getting to hot and combusting or fuel leaking on the the extremely hot engine and combusting granted you have the three elements required in order to have a fire.

In other words, you want to use up all the engine oil before your engine temperature begins to rise and locks the engine.  You're basically asking for a little more time with the engine running.  What I think you don't realize, is how fast one of those aircraft engines will seize up once it is empty of oil.  Besides, that spike in temperature actually begins long before you are actually out of oil.  As the engine has less oil, the oil has to absorb more of the energy from the engine.  Less oil absorbing the same amount of friction equals hotter oil which leads to viscosity break down etc etc.  The engine failure beings before you are actually out of oil.

I too am having a hard time understanding the request in your post.  As it is now, if you recieve engine oil and/or radiator damage only, but your engine is still good (green), you can keep on flying until you run out of oil (engine oil hit) or until your engine gets so hot it seizes up (radiator hit).  At which point and time the engine itself is dead/broken/red and should be shown as such in the damage list.  I have successfuly shut down engines with oil or radiator damage and saved what limited time they have left on them for when/if I need it.  On single engine aircraft I can also usualy cut back on my throttle/rpm/prop-pitch and milk a decent amount of time from my engine before it dies.  Going full burn though and staying in a fight, ignoring the oil and radiator damage, my engine won't last very long at all.

Maybe you don't know this, but when the oil runs out or when the engine gets too hot from a bad radiator, it just locks up (it doesn't scream or spew out sparks and flames until it or you decides it doesn't want to anymore, it just stops turning and is dead).  You can't force a locked up engine to do anything but nothing.

yesterday i was mad, had 9 kills and engine oil hit, didnt make it home, so i posted about it, i usually dont make sense when im aggravated,

so these engines wont take abuse, just quit when they want to and doesn't wait until you say so? ah ok i see. didnt know that of course, well their now way i could defend myself, ill just say it, i feel stupid, i know all about oil and stuff, i was just aggravated and dont make sense when i am so.

There are a few tricks to get home when you have taken an engine hit.  Trade altitude for airspeed.  But do it sparingly.  Turn your engine off and try and maintain a gentle descent.  Best glide, I believe, is also the same airspeed as best climb.  So, dive just enough to maintain that best glide speed.  Turn your engine back on and run until you have regained some of you energy/altitude, cut it back off and hold best glide speed as long as possible.  Repeat as needed all the way home.  I believe that there is an advantage to adjusting your engine RPMs to reduce prop drag while the engine is off, but somebody else will have to discuss that.

Also, I try to save that last little bit of oil for landing if possible.  If you land dead stick (engine out) you only get one chance, having a little power will allow you to make last minute adjustments while landing, or possible a go around if you muff the landing completely.

On a side note, I have used the engine on/off best glide technique to make it home in a bird that is nearly out of fuel also.

I think he asking is when your oil get hint that you can go out of your plane and fix it up. Tell me if I'm right or not.  :lol

I like you.  If you knew how many times public school board officials here spend their time to vote on increasing their salaries and bonuses instead of on issues that would help the kids, you might want to publicaly lynch them like me.

I think you have what we would call "an idea from a Hollywood movie" or two.  I'm not a pro, but I have seen engines seize up in my life (*spits & curses*).  There is minimal to zero "grace" time after the engine oil pressure cuts out (0) and the engine seizes. 

One, and probabley the best example I can think of for you to understand, was an inline-4-banger on my brother's '88 Honda accord (dinky weaksauce engine compared to a V12 AC monster-of-a-beast-of-an-engine).  He had just entered a long uphill tunnel and noticed his oil guage was just bottoming out as we went in to it, and overheating was already occuring (between normal and max).  Tunnels don't have shoulders, and especialy at night (which it was) are not ideal to pull your car over in, so he decided to try and make it for the end and the nearest open shoulder, I agreed with him.  By the time we got to the end of the tunnel (less than a 1/4 of a mile and not very long to get to at ~45 mph) engine temperature was beyond the temperature guage max limit and we were about 200ft from the nearest open shoulder, right as we made pulled off the pavement, *clank* engine seized up.  Was the end to a good car with a ton of miles on that engine. 

I'll leave to you the comparison of how much abuse an old inline-4 made by honda in 1988 for a car can take compared to a V12 made by Rolls-Royce in 1940 for a high-performance fighter aircraft.

My brother felt aweful about killing it, he was only 17 or 18 at the time and wasn't watching his guages as well as he should of.  I reasured him it wasn't as much his fault as he thought it was.  It was an old engine with tons of miles on it (had over 280k), so it was likely near the end anyways.  I also told him that he probabley was watching his guages, but none of us really know how long or how fast the car was loosing oil pressure at the time, but it was true he didn't catch it until it was just hitting zero.  Most importantly though, I told him he caught it before the problem occured, but due to the condition of the road at the time we had to push onward to a safe stopping point, and any crash/wreck/busted-down-car you walk away from safely is a good one.
