It is known that compressor oil will slowly coat the inside surfaces of air conditioner evaporator and and consenser coils thus reducing the thermal conductivity and consequently reducing the cooling efficiency. Over time, what is the typical percentage reduction?How much does air conditioner cooling efficiency decrease over time due to compressor oil fowling?
Although oil vapor from the compressor will enter the evaporator and condenser and condense, it is important to remember that A/C systems are closed systems... Therefore, as oil vapor is being leaked into the A/C system, it is also being returned to the compressor. I guess I can't really answer your question specifically. But in theory, at some point the efficiency loss peaks and levels out due to the fact that oil from the system is also being returned to the compressor.
It is also important to note that the distribution of some oil throughout the system is a desirable ';side-effect'; of the operation of the compressor, as it prevents the corrosion of the condenser and evaporator, as well as the piping in between.How much does air conditioner cooling efficiency decrease over time due to compressor oil fowling?
like any application, proactive maintenance remediation may improve performance
sometimes it makes not defference, if your application is near the edge of the envelope, address the causes for problems
the link is for air compressors, not air conditioner, but a/c usually does not have an issue
but that is my opinion and I don't know much
I think I have had nothing that could be measured. It also may depend on contaminates. I have had some last very long with no problem.

What causes oil to leak into my cars cooling system?
Head gasket, cracked head or block!! Good luck!!!What causes oil to leak into my cars cooling system?
In most cases the transmission cooler which is located inside the radiator on vehicles with an automatic transmission can rupture and mix oil with the coolant and usually looks like a strawberry milk shake.
A bad head gasket will usually cause coolant in the oil not the other way around.What causes oil to leak into my cars cooling system?
most likely a bad cylinder head or gasket
blown head gasket will not cause oil into your cooling system, instead it blow your coolant of the cap and cause engine overheating.
a crack on the block, means a coolant into your oil, oil will become milky and frothy.
two common source of oil into the coolant are the engine oil cooler and the water pump.
crack on the oil cooler tubes injects oil into the coolant,,this happens when the engine is running since oil pressure is higher than the coolant pressure.
bad water pump seal causes oil into the coolant, the seal separates the water from oil. once the seal is bad it will leak oil into the coolant side, specially when the weep hole in the pump is plugged. replace the pump to correct the problem.
a leaking head gasket or a crack in the block or head of the engine either way not good to have oil in coolant engine is probly junk
You More than Likely Have a Head gasket , Warped head , or a cracked head...
Year, make ,model please. In most cases, its a head gasket leak.
busted water jacket in the head or blown head gasket between water jacket and cylinder. this will cause it to leak into the water line. and what goes into the cylinder comes out of the exhaust in the form of steam.
Bad Head Gasket!
a blown head gasket or intake manifold gasket.mineral foundation

When oil Leaks on the ground.. What makes all the cool colors?
is it some kind of mineral in the oil or what?When oil Leaks on the ground.. What makes all the cool colors?
It is actually a complex process of refraction and total internal reflection which breaks the light in its components color and then reflects back toward you.When oil Leaks on the ground.. What makes all the cool colors?

How much oil is full on a VW air cooled 1600 dual port stock in quarts or liters?
My dipstick is messed up!!!!!!!!!!!How much oil is full on a VW air cooled 1600 dual port stock in quarts or liters?
Assuming you do a full oil change, and that you do not have any accessories like an external oil cooler, the crank case will take 3 us quarts.
While you are doing it, lets fix your dipstick.
1) Drain the oil. (clean the filter and get new gaskets). Let it drain for about 10 to 15 minutes to get as much oil out as possible.
2) Reinstall the filter and the plates, tighten the nuts and add TWO (2) quarts. Wait about 5 minutes and pull the dipstick. It should be on the 'low' mark. If it is not, make a new mark at the oil level with a hacksaw or etching device., wipe off any metal parts and put it back in.
3) Add the third quart and make a new line for the 'full' level.
now your dipstick is correct (and your oil is changed).
.How much oil is full on a VW air cooled 1600 dual port stock in quarts or liters?
change oil, clean oil strainer, put 3 qts back in an you ok. 2.5 is correct but 3 qt will be ok

Stupid Question but Do you check oil while the car's been running or while its cool?
I have no idea bc I'm extremely ignorant of most things that have to do with cars.Stupid Question but Do you check oil while the car's been running or while its cool?
you check the oil at anytime doesnt matterStupid Question but Do you check oil while the car's been running or while its cool?
ok the honest truth you check the oil when the motor in not in operation. (meaning not turned on) the reason for this is that most auto makers have it where the oil pump senser send a certian amount through out the whole motor lubericating the inside to allow it to function without burning out valves gears and other important parts.
the best time to check your oil is in the morning when you 1st wake up due to the oil draining back into the oil pan to give a true reading.
the only time you check a fluid while the motor is runing is your transmission fluid. the reason for this is transmission fluid cirulates through the transmission seperating the gears from colliding with eachother.
Your car has to be shut off. It doesn't matter if you drove the car, because a lot of people would drive to the station and have them check it. So turn off the car and let the oil settle for a short period of time then check it. Same thing with the transmission , check when the car is shut off.
Either way, but you get a more accurate reading after all the oil drains down into the crankcase after the car has been parked awhile. Also, the car needs to be parked on level ground to get the best reading.

When the car has been running the oil is thinner and could be lower then it really is. Check it on flat land and while it is cool.
Here's something else for you.. http://www.wikihow.com/Check-the-Fluids-鈥?/a>
YOU CHECK OIL WHEN THE ENGINE IS OFF AND HAS SETTLED A BIT. YOU CHECK THE AUTOMATIC TRANSMISSION FLUID WHILE THE CAR IS RUNNING. IF IT IS A NEWER VEHICLE YOU REALLY DONT HAVE TO WORRY ABOUT THE TRANSMISSION FLUID LEVEL. YOU SHOULD CHANGE THE TRANSMISSION FLUID EVERY 20-30,000 MILES.
drive it for about ten km. then turn off the car too check the oil motor should warm up first./ transmission should be put through all gears then back to park while it is running and there is a cold fill range on the dip Stick
When checking the oil , check the oil when engine is off.. cool or warm.
Check the transmission when trans. oil is hot with engine running in park.
You check the oil when the car is running, and the transmission fluid when the car is cool.
The car should not be running when checked, but can be checked, when off, hot or cold, and on level ground.
You warm up the oil then wait 10 min and then it drains out easily. Don't attempt to do it sooner than 10 min because oil is still making it's way down from the motor.
Either but make sure you car is on level ground and if you do it warm be carefully not to burn yourself.
It doesn't really matter. Check it both ways. See if you notice a difference.
i go to the shop where i have my car oil changed and let them check it for me

Is crude oil blood of the earth that keeps our planet cool?
Does any one know if oil protects the earth in any way?Is crude oil blood of the earth that keeps our planet cool?
Who knows? While it is true that oil is produced by the decomposition of carbon based life forms, the question was not ';what is oil made of?';, The question was, basically, ';What purpose does oil serve while it is in it's natural environment? While oil's function may not equate with the function of ';Blood';, it is painfully obvious that the more we take out of the earth, the more dysfunctional earth becomes.Is crude oil blood of the earth that keeps our planet cool?
There are two answers to this question. The first is the scientific one which is no. Oil is the end product of the anoxic decomposition of micro organisms, trapped in porous sediment that has been heated and compressed over time. The second answer is if you are from the bible belt and is Yes. Oil is the evil squeezed out of all the demons by God and his angels during the war between heaven and hell. It was put to good use by God to cool the earth down and stop use burning our feet as we walk around.
Oil is decayed flora and micro organizms and to my knowledge does not protect the earth. Sap is the 'blood' of trees and trees help to cool the earth to a small extent. Primarily the ozone layer protects and cools the earth.
No. Oil is a millions of years old reserve of long dead organisms. And we're running out.
It doesn't cool the Earth. Whoever led you to this frankly bizarre way of thinking is clearly a moron.
Nope crude oil is the remnants of huge tropical forests, its carbon based and has settled in vast underground deposits, where you got that cooling thing from is totally wrong!
No it's dead dinosaurs.

on the number 3 cylinder the head gasket cracks all the time and waprs the cylinder head from over heating. what you need to do is get a new head gasket and take the head to get machined maybe you are lucky and you can reuse it but i have replaced 4 engines on the last 7 3.1 gms i have done. because the cylinder walls got so hot that the number 3 cylinder cracked and coolant and oil mixedWhat wouyld be the cause of oil in cooling system of gm 3.1 after it has overheated from the cause of faulty w
What miles on this engine? whatz it in? Failed water pump? Aluminum heads cast iron block motors don't like over heating. I doubt there is much left to save. By the time you get both cyl heads off and motor out of the car to have the engine block tested you could have a used running motor in there.What wouyld be the cause of oil in cooling system of gm 3.1 after it has overheated from the cause of faulty w
Cracked cylinder head from the over-heating?
start with put in some pepper(black ) most of a can if it no lomger shows oil in your cooling system its likely the head gasket if not you have a cracked head or block if it is expensive
A crack somewhere. A blown gasket, possible an intake gasket because of the engine design
i would say you have a blown head gasket or intake gasket. If you car is overheating, then it is head gasket. If it is not then it is intake gasket
