The law requires you to either recycle used oil or return it to a place that will recycle it. This is why most parts store will accept used motor oil.

Yes indeed, I'm sitting here with a "new" 81 240dl...134a conversion...cooling well but don't like the thrashing the compressor is taking...a volvo 245 134a conversion...smooth but not very cool...an 89 volvo 134a conversion smooth and cool enough ...so far...and a 90 volvo 760... r12 works smooth but not very cool at all... and west Texas summer just getting fired up...

Don't know what I'll be doing yet, but my decision will certianly NOT be an uninformed one ....thanks to all!

In Australia, R12 is not an available airconditioning gas. To avoid having R134a, installed, I asked around and found that Commercial refrigeration uses HR12, a hydrocarbon (Propane/Butane +++something IIRC) and performs in much the same way as R12, and really kept me cool in 40'C heat.

I have been advised that it is flammable, but that half litre of flammable gas (if that much) is much less of a hazard than the guy next door with his 80 litres of petrol and 80 litres of LPG in his SUV.

If an accident were to happen, I would rather be in my 300D with half a litre of flammable gas and 80 litres of biodiesel/WVO blend, than in that SUV.
And that in not in relation to the relativer safety of the vehicles, just the volume of fuel involved.

Seems like a good time to bring this back up into view... especially since I accused Diesel Giant of being like Redfox....

A lot of people have read this thread... But it has been a year since it was on the front page.... perhaps some people will appreciate that some of the questions being posed now have had good discussions in the past...

I will answer and expound both... but need to do a search...

Huhh??

Too many riddles, plain English please.

Gary F,
First, I ASSUME that you know that FREEZE12 is 80 Percent 134a ?

Second, DIESEL GIANT is a DEALER.... and SELLS FREEZE12...

Third, I suspect once you see my reference to an EPA site you assume the reference is to following the ECO laws ( and don't go read it ).. when most of the time it is to show a reference having to do with things like using BLENDS like FREEZE12 and then trying to find a shop which will service it when you need it....
A couple of years ago we had the same kind of activity out of REDFOX trying to sell DURACOOL.

People still post saying they are thinking about using FREEZE12 or some other supposed ' R-12 ' drop in replacement... like there is an easy shortcut to doing things correctly...

The refrigerant oil carrying question is very important to people using the Delco compressors.. I don't want anyone to choose FREEZE12 or ANY other blend without FAIR WARNING... to do their research before making their decision.. and since the EPA and Aircondition.com have done nice writeups I give those as references.

The higher operating pressure are also a factor .... but it is easier to visualize a lack of good lubrication causing failure down the road.
If you read about BLACK DEATH on the AC forums... you understand that it often takes a year for complete failure to occur... this is one part of the equation which gets left out of DIESEL GIANTS claims about FREEZE12 working so well.... if he DID have failures a year later do you think he would post with a mea culpa ? LOL

My definition of FAIR WARNING when dealing with someone who is willing FOR ECONOMIC purposes to make misleading statements is to try to make the warnings appear on the same page each time the misleading/incomplete items are posted.

You're making a very bad argument here.

Lots of things are illegal. Speeding is one of which we are probably all guilty. But what's the penalty? Is it accidentially a lower penalty than driving while drunk? Or could that be intentional?

You get popped for speeding, and in most cases, you're on your way with a ticket that you can simply mail to the proper court.

Let's say that your neighbor sees you pass him at a high speed on the highway, and calls the cops. Will they come to your house and give you a ticket? I don't think so.

Let's say that you do improper conversions on air-conditioners on the side, and you neighbor notices, gets irate at the traffic, and calls the EPA. Will they come to your house and give you a ticket? They'll come to your house, but the ticket is something like 25 grand, and your nosy neighbor gets a cut.

Do you see the difference?

I use Freeze 12 exclusively and dont use R-12 anymore. I get better performance with it, colder temps and lower pressure. I have done LOTS of Freeze 12 conversions for myself and customers and have NEVER had a failure or complaint with it.

When you get near 30 degrees at the vent, who can complain.

FWIW, I have two cars that were converted to R134a from R12, so they already have the PAG oils in them.

The heat & humidity of Florida is TOO MUCH, so I've converted them to ES-12a.

Both have gone over year, and the temp are cooler than R134a and the pressures are lower.

:-) neil

^^^I did the same thing, used ES-12a that is. This morning I had vent temps of 38.

I just spent a good part of the morning reading this thread. It was good reading.

I have 134 in one of my 6.9 and it blows really cool. It has a new condenser, new servo and new hoses.

It really works great.

My other 6.9 runs fresh R12 and it's cool but not as cool as the 6.9. That's with a new condenser. But it does have a problematic acc servo.

I do remember when buying the condenser that it came in a box with big bold writing that said WARRANTY VOID UNLESS R12 OR R134 IS USED.

I'm not against the alternatives, but I do know that R134 works perfectly well in older cars such as the W116 when it's been converted properly.
