I just realized that I bought the 'new' Prestone "All Makes All Models Extended Life Antifreeze/Coolant" and apparently it can work with 'any' coolant?

Now, my concern is with this new compatibility, does anyone think/know if they've compromised they're green stuff? Anyone know if there is a difference in cooling efficiency versus their old formula?

They're website didn't reveal to much info.

Thanks

Is it the pink stuff? A few years ago member reported it eating coolant seals and that it wasn't a good mix. Not sure if it is the same stuff as I use Evans, but I would definitely wait until you know it is compatible.

I don't think it would matter if it had extended life. It's very unlikely it will have better thermal performance than regular stuff. You should change the coolant regularly to prevent buildup and galvanic attack - keeping it in there longer is just a bad idea, IMO.

I acutally have the stuff in the back seat of my car right now. At lunch, I'll go poor some out and also look at the ingredients list. Worst case is I'll just buy some more after work.

Tasty... hmmm, where are those cats?

I try and change the coolant every two years but since I'm changing the radiator I'm going change it now (1 year). Flush with distilled water and then 60/40 or so mixture. All I've ever used is the regular prestone green stuff (ethylene glycol) but I don't know what 'else' this stuff has or even if its ethylene glycol.

I've used it for about 2 months now... no issues. 50/50. It says it's still compatible with any, but I still flushed my old stuff, and poured in this new stuff... no issues thus far...

There just really isn't any good reason to use anything but good ol' green coolant. I read a tech article a while back on the differences between the two, and the best policy is to stick with the coolant that the car was designed for. Stuff like the seals in the water pump are designed to be compatible with a certain coolant, and if it isn't, there could be problems down the road.

Really, either run green coolant or Evans NPG. There's no good reason to run anything else.

That's kinda where I'm at... I always you green coolant. Prestone. But they changed up some stuff, well, unless its just marketing hype. The new label states that this coolant is compatible with all engine types and some other such things. My concern is if this stuff has been changed enough to adversly effect our FDs.

Any other good easy to obtain green coolant to use?

I doubt they would discontinue the green coolant - I've never had problems buying it.

Soooo, here's the list O' ingredients:

ethylene glycol (107-21-1)
diethylene glycol (111-46-6)
sodium 2-ethyl hexanoate (1976-89-3)
sodium neodecanoate (31548-27-3)

Hey, it's still green.

stick with what's in there. If you are willing to flush, and don't want/need $$NPG+, then go with Zerex G05 5yr/100k. Chrysler and ford have had no issues with their variants. It's a hybrid between dexcool and conventional, but non of the bad stuff from either. I use it.

Whan I put the new radiator in, I went with the Prestone Orange stuff. It is designed for bimetallic engines (ones with aluminum).

Peak has a Lifetime coolant now. Not sure, it's still an ethylene glycol base? http://www.peakantifreeze.com/peak_global_lifetime.html
