Ask me about my Mobil 1 experience and an Amazon delivery by USPS, please. Then ask me about the 5 quart mess I had to clean up with copious amounts of brake cleaner and a rented pressure washer.
I don't know about your couriers in your area, but mine do not give a rat's ***.
USPS won't carry stuff like that, at least around here. Comes UPS or Fedex. M-1 comes from WaMart, local store. G05 a drive all the way across town to the CarQuest store (~4 miles) where they keep it in stock. If I plan well enough in advance, I get it when I'm out running other regular errands. With several cars using the same stuff already, it would seem prudent to just buy enough for all of them at once. By my thinking anyway.

With that mentality, you probably should never buy eggs from the grocery store, better off driving out to the farm... What evs.
I guess you found your excuse to not use the G-05.
Now with regard to restoring a topic that is rather heated on here between coolants, most of the stories I have read relate to Dexcool and its 2EHA concentration in the past. Nowadays, I am not so sure it is toxic. I just have not seen any catastrophic failures with water pumps or gaskets.
One possibility is that our timing belt and water pump service intervals interdict corrosion by coolant as we need to drain and refill it regardless.
My 2 cents... I believe changing types of coolant adds risk of reaction between the old/new coolant which can lead to problems. So in my mind if you know what coolant is in the car and you are not having problems then stick with it. If you do need to change give it a good flush with water.
For the record I use G48.
The previous owner had some yellow stuff in there which I didn't know what it was. When I took off the water hoses and found yellow crystallised deposits everywhere. I flushed and moved to g48. Shortly after I replaced a leaking radiator.
Andy, part of your logic escapes me. Looking at the coolant that comes out is just a part of the diagnosis. Look carefully at the metal to make sure it's still there. It's easy enough to pull a radiator hose off and look at the nozzle it attached to on the engine. Is all the metal there, or is it pock-marked with corrosion, or perhaps covered with crystals? That's an indicator of what's going on with the rest of the aluminum in the engine.
My logic relates to someone showing me valid proof that G05 is not the only non-dealer antifreeze that is good for our cars.
I went further than just pulling hoses off in 2008 and had my end tanks resealed. Radiator shop that did it said the radiator was in great condition.
In 2013, it still looked good after draining coolant and inspecting the system, which even involved the water pump replacement.
I went through that motor and found no corrosion issues related to the coolant I used. Hell even my pump bolts were in good condition and never broke!
Now does that mean I am an advocate of Prestone? No. Quite honestly I am getting tired of staring at 4 different types of antifreeze in my garage and want to consolidate just to one type. G05? Yeah ok. It works great, got it. Is it commercially available in my area? Not so much. Napa always runs out of it here hence my pursuit to other towns for it. I did however stop by yesterday and order it in bulk for my car and for the other invasive species of Mercedes in my garage.
Bottom line is this: Prestone All Makes and Models 50/50 is not bad stuff and my radiator shows living proof of that as well as a 5 year old core water pump I am looking at. Don't be afraid to get the cheap stuff like this at Wally World or O'Reilly if you cannot find Zerex G05.
Now onto the next obstacle which is draining and flushing coolant on a block with frozen drains. The neigjbors can have the rest of my antifreeze as I have no use for it.
Sorry to resurrect such an old thread but it's probably better than creating a new one
It seems G05 is the right choice. I just drained my coolant and it's green (I just got the car, so no clue what it may be). The G05 coolant at my local parts store was the orange Prestone, but it says it's for GM cars. I'm guessing the main thing is that it's G05 and the recommended engine manufacturers is less consequential.
After reading about how mixing coolants can cause them to sort of solidify, would it be risky to put that orange G05 coolant in mine knowing that there will invariably be some of the green coolant still in the system? Would it be best to thoroughly flush the system?
If you want to change coolant types then simply flush out your system with distilled water (about $1.00 per gal.) the system holds 4 gallons.
Be sure to have your heat on, and then run up to temp.
Let her cool down and then drain (must do the two block plugs and not just the radiator.
Do it twice or until it runs clear
Then use whatever type of coolant you like.

Thanks in advance
Green coolant is invariably what folks in the USA refer to as Prestone- this known as IAT coolant and was the coolant originally used by Porsche when the cars were new. G-05 coolant was the first second generation long life type coolant brought to market in 1994 as a universal coolant to replace IAT coolant that had a shorter service life. G-05 is a straw yellow colour - orange is the colour of Dexcool and that should be avoided like the plague.
G-05 coolant is commonly used by 928 owners but it was never formally approved by Porsche for use in our 928's. This coolant was developed in Germany by BASF under their retail name of Glysantin. The longlife coolant of choice is Glysantin G-48 and it is coloured blue. VW Audi call it G-11 in their specifications and it is what you get when you purchase Porsche coolant. When you purchase coolant as G-48, what you get for $10 will cost you $20 when in a VW bottle and $30 when you purchase it in a Porsche labelled jug. A popular coolant of choice these days is Pentafrost NF- this is approved by VW as meeting their G11 spec just that it is not formally labelled as G-48 - probably a iicensing thing.
G-05 is essentially the same stuff in terms of corrosion protection chemistry - the difference is it contains another component to protect wet liners in diesel engines and that of course is not needed in our motors but does no harm to them either. Theory says these coolants are backwards compatible with the original IAT coolant but if changing coolant types better to fill the system with water and drain it.
All the above is kind of ironic given that today the Prestone green coolant is rated for 150k miles or 5 years! This what I use.
I received an email from Xerex yesterday offering 50% off on their antifreeze. Went to their website entered in my car selected G40 and it told me that didn't match my car. I chose G48 and that didn't match.

Do a search for Glysantin and Xerex G48 datasheets- there you will see that this brew is the correct one for Porsches up to MY1996.
Although I cannot be 100% certain I believe it is exactly the same stuff as G-05 just that BMW, VW and Porsche officially approved it for use in their vehicles in 1998 and probably at a cost premium for the privilidge. For sure the chemistry of protection is the same .
G-40 has never been approved for use in our vehicles. This pink coloured coolant is what Porsche use in later models like my Cayenne turbo S. As i could ascertain there are three variants of it and the latest varient supposedly is backwards compatible. I found some info that suggested that it will not protect steel from corrosion but I could not verify that.
