Car Forum / BMW Cars / May 2007'95 318i A/C
I've got a '95 318i that we're doing some A/C work on. What I need to know is how much oil to use in the compressor to keep the system running optimally. I'm not great at auto repair and will be working with my father-in-law. He's got the experience, just doesn't know how much oil to use in the compressor/other areas. >I've got a '95 318i that we're doing some A/C work on.

I've got a service manual (Bentley Publishers) for that car, and the specs they give are: R134a -- 2.2 lb ± 0.05 (1000g ± 25g) The oil you need depends on the kind of A/C system. The Nippondenso takes 120ml and the Seiko takes 150ml. If you are buying R134a at the local parts store, it probably has oil already in it. You should read the can. If you are working on the AC system and need to ask stuff like this, you should buy the book. >> I've got a '95 318i that we're doing some A/C work on.

How much does it cost to get a system re-gassed professionally? Here in the UK one cannot buy gas unless one has a business account with one of the major suppliers BOC or Air Products and are registered users. A recharge is anything from $100 (US) to $200 (US) depending on whether Main Stealer or independent. Is it really worth it to mess about like this? > Here in the UK one cannot buy gas unless one has a business account with > one of the major suppliers BOC or Air Products and are registered users.

Now don't go confusing him with facts like that Dave. He has a really good head of steam up in this argument... Signature-Fred W >> Here in the UK one cannot buy gas unless one has a business account with >> one of the major suppliers BOC or Air Products and are registered users. > >Halfords sell it. Yes Dave I noticed that the other day but it is in "fool proof" containers and only meant for a top-up not a full re-gas. The same applies Stateside but the environmental regs are not enforced so stringently. I believe that R134a and the newer stuff is based on LPG products (butane and propane) which I understand has been used by some ignorant people that then were surprised when the whole thing blew up! The Hotpoint service guys carry aerosol containers of the stuff for when they fix refrigerators and freezers and I have, in the past, topped up a system with one of these when it was R12. But really when you look at the Halfords' price for 2 it is still cheaper to get it done professionally and tested. > How much does R134a cost States side? I guess you haven't figured out that Google thing yet, huh? Well I'll answer you anyway. Not much. Less that $10. > How much is the oil and can you buy it in > small quantities? As Jeff already said, it comes in the refrigerant. But yes, small cans can be bought and they are cheaper than the R134a. > How much does it cost to get a system re-gassed professionally? Quite a bit. Over a hundred bucks typically. > Here in the UK one cannot buy gas unless one has a business account with one of > the major suppliers BOC or Air Products and are registered users.

Just because they do things a partricular way in England doesn't mean it's the only way, nor the best way. > Is it really worth it to mess about like this? Duh, yes. Signature-Fred W >> How much does R134a cost States side? > [quoted text clipped - 22 lines] > >Duh, yes. Piss off Fred. I used to live in FL and I know that we British do things differently to you guys over there. I would like to still be there and probably would still be there had my EX-wife not got home sick (notice the EX). I do think that some thing we do or the gov' try to control is stupid and likewise with the US gov'. 50 pounds or 100 bucks is reasonable not to get dirty, get a guarantee, have it tested for leaks. DIY is great for the feeling - I saved 10 bucks???? Sorry? $10 (5 pounds) that's a pint of beer or 2 - just over a gallon of gas (imp) - 2 hours car park in London -- wouldn't even get you into London during the working week-day (tolls). pack cigarettes in UK. Really not worth pissing about. >>>How much does R134a cost States side? >> [quoted text clipped - 40 lines] > > Really not worth pissing about. Piss off yerself, pal. If you long for living in FL (bad choice IMO) and you're able to see both sides of it, then why do come across as such a pompous hater of everything US? And you know you do. I'm sure it's intentional. If you could read and comprehend I told you it would *cost* $10 for a can of R-134. Minimum cost to have is done is $100. My elementary school training tells me that potentially saves one $90, not $10. $90 (that's 45 pounds) that's a keg of beer over here, enough gas to fill one of our big-a.s SUVs, half a dozen (contraband) Cuban cigars or a night in the Holiday Inn Express (where I did not stay last night). Quite worth pissing about in my experience. Plus you don't have the inconvenience of having to bring the car in to the shop, leave it all day, get a ride home, then reverse the process to collect it. Oh, and leak testing would be an additional charge and there are seldom any guarantees on this kind of service work. Signature-Fred W >>>>How much does R134a cost States side? >>> [quoted text clipped - 45 lines] >a pompous hater of everything US? And you know you do. I'm sure it's >intentional. No NO I do not hate everything US - I love most of the country and a few of the cars you produce even if they don't last very long (style wise that is). It's just that every so often one does come across complete arseholes (and you are going to say I'm one - if so - so are you) but all insults aside saving $90 today and having to spen another $150 tomorrow is not saving much if the filter/drier and or condenser are kaput too and / or the seals in the pump are shot. Isn't it better to know rather than spen on everything but the real problem or is that part of the fun too? >If you could read and comprehend I told you it would *cost* $10 for a >can of R-134.

I agree there is that to it if and only if it didn't need anything else. 9/10 the condenser has a minute hole and it will leak out in short time so it's another $10 then another then another eventually you would have spent enough on R134a to get a complete new system installed.

I don't know about the $100 charge you all are talking about, but in California it's more like $250 - $500 depending on what needs to be done! >On May 28, 2:32 pm, O...@nowhere.com wrote: >> >O...@nowhere.com wrote: [quoted text clipped - 88 lines] >California it's more like $250 - $500 depending on what needs to be >done! Perhaps our Tony Blair is good friends with your Arnie!

Some refrigerant is bound to leak over years with the common car type system - this is intrinsic because of the exposed pulley drive and therefore seal. Domestic units like fridges can enclose the entire pump/motor assembly to prevent any leaks at all. So all will need a recharge eventually. How often depends on a number of factors other than obviously design. If all that's needed is topping up the refrigerant $100 sounds right - here in the UK I paid 60 gbp. If repairs are needed the sky's the limit.

What I need to >>> know is how much oil to use in the compressor to keep the system [quoted text clipped - 20 lines] > it in > small quantities? I bought a double-can for under $30, that included the low side pressure guage. I think the standard can is something like 15oz, and the double that I bought was 30. Maybe the actual numbers are 14.5 and 29. Whatever. They sell it at the local autoparts store. There is no capacity to evacuate the system, and the idea with this stuff is that the system is otherwise in good condition, but the charge of refridgerant has simply seeped out. I don't know if refidgerant "dies" or has to seep out, in order to require the addition of more. > How much does it cost to get a system re-gassed professionally? I screwed my car up a couple of years ago and had to go to the shop for proper servicing. It seems that I paid about $100 to have the system evacuated and recharged. Of course, the shop has the equipment needed to capture the juice that comes out. > Here in the UK one cannot buy gas unless one has a business account with > one of [quoted text clipped - 4 lines] > > Is it really worth it to mess about like this? If all you need is to recharge the system, yes it is worth it. It sounds like you need much more than a simple recharge, and without the proper equipment, it is clearly (in my opinion) not worth it.
