i cant speak to how it goes in a 300d but any ac system i have worked on at the shop we have just added about an oz. at the end. for example, in a Chevy silverado, i replaced the compressor and receiver drier, then once everything was back together, evacuated the air and charged the system. once the system was charged i fired up the car and using an oil pump which injected oil via the low side service valve. i injected about 1 oz. of oil, and the duct temps immediately dropped. i would recommend also adding a bottle of "ice 32" which is a lubrication enhancer. ive seen with my own eyes the 10 degree difference it makes at the vent. it works by lubricating the compressor and condenser, aiding in heat transfer and in the end dropping vent temperatures significantly.

i dont claim to be an expert, just sharing my experience.

best of luck, Jack

And what made you think that ' lubrication needed to be ' enhanced' over and above the new oil being installed ?

If someone follows your out side the FSM directions and it messes up their system.....will you pay for it to be corrected ?

We have no way of knowing what reason you have to be promoting ' ice 32 ' .... do you know what is IN it ? Do you have independent laboratory test results on what it does or showing it will not cause any harm to our AC systems ?

Is that addition going to cause regular AC shops to refuse to work on someone's system worried it will contaminate their expensive recovery machines ?

Please don't. Ignore the perfectionists here, they live in the dream world, not practical world. Share your experience. This is what the forum is all about.

Please don't! New ideas always welcome here. DO NOT let oppressive/ repressive individuals deter you from posting your experiences.

Do you mean egomaniac? No one can oppress or repress me on the Web.

For years we had people with FINANCIAL interests in certain products who would post glowing reports on things where just a little investigation would show that they had drawbacks which were NEVER mentioned in their ' reports' .... like it being a Blend, or no evidence that it was compatible with the oils used in our AC systems.. VERY important on OUR machines since many are the R4 Delco which HAS NO OIL SUMP.... and relies on the miscibility of the oil in the refrigerant for its lubrication...
These included Redfox and Diesel Giant ... both of which SOLD Duracool... and there have been others....
So an anecdotal report of a ' additive' with nothing else... gets flagged as ' needs investigation.... and you can that I provided what I could find as soon as the ' ICE32' subject came up..

Interestingly, my new compressor came with ice32 in it, but i was planning on draining that to use straight pag150

Call Carlisle back and ask them what the deal is...
is there literature which identifies the ' ice 32'?
It could be that it is supposed to be in there going forward...
or that it was good for long term storage until the compressor is put into service...
what literature was there that identified it came with the new compressor ?

Demothen · #11 07-02-2016, 09:49 AM

The limited documentation on the compressor said to leave it in the compressor. I think it shipped with pag150 and ice32, so it would probably be safe to leave it. I need to look at the warrantee to be sure, if i need to leave that oil, it makes sense to drain and measure it, add the correct amount back to the compressor, then add the correct amount if fresh pag150 to the drier, evap and condensor.

I thought the fsm wanted you to drain the new compressor and add fresh oil, but i may have been mistaken.

I want to try to retain the warrantee on the conpressor if at all possible.

leathermang · #12 07-02-2016, 10:09 AM

Keep the warranty in place if they tell you what to do.
The draining was in a refurbishing where all the other oil in the system was cleaned out.. so you needed to know how much was in the compressor( and that it was not contaminated ) d to make the total proper... with new oil it was a matter of measuring it so you could see that it was properly installed and what the total AC system would wind up being..

The instructions say "this unit comes filled with 1.5 oz of oil with ice32. DO NOT REMOVE THIS OIL."
So by my math, thats 44ml - call it 45, i am not going to be able to measure exactly to the ML. That means i need to add 125ml of oil to the compressor to reach 170ml total. I think i will use the supercool pag 150 that Carlisle's shop recommended, then add the correct amounts to the condensor, evap, and drier that you provided earlier. Seem right?
Not sure how I will get oil into the evap, may need to put it into the input side line, since I think anything i add will drip back out.

Seem like a plan?

leathermang · #15 07-02-2016, 11:08 AM

Ok...... good they said how much was included....
the ICE32 appears to be just PAG 100 oil...
so that is comforting...

That does sound like a good plan...
I think the oil you put directly into the evaporator has to be put downstream of the TXvalve....
so what about that rubber line used on the end of the flush can which you used to connect to the evaporator ...as a way to install that oil ?

For the record .. the AC FSM shows converting the old Txvalve into a ' fitting' by taking its ' innards out '... to access the evaporator with it in place.. so you can make connections with lines attached to , first, the flush equipment, then to the nitrogen flushing equipment then the oil insertion equipment, etc...
