I'm going to add even more confusion. For starters, I got my 488 at about 4 years old, 1 owner and only 5,500 miles, and it had perfect service records, so I'm pretty sure that it has OEM fluid in it. My fluid is a red/pink color (same as Glycoshell) and even though that one site said that the color of the Carix Long Life was yellow (but the title said red), I found an MSDS sheet that said it was red. You can also see in post #23 that it's the same color that is in my car. And another thing I noticed is that a red/pink coolant is usually an OAT, not a HOAT (but I know color is not a reliable indicator). I've never had so much confusing info dealing with cars in my life. Image Unavailable, Please Login
OK, ready for this?!?!? I now found out that there is a pink/red Carix Long Life coolant AND a yellow Carix Long Life coolant. How crazy is that? The same name but a different color. Then I found this: "Carix Long Life Yellow Coolant is a Hybrid Organic Acid Technology (HOAT) coolant, while Carix Long Life Red Coolant is an Organic Acid Technology (OAT) coolant. HOAT coolants are a blend of OAT and silicate additives, offering extended corrosion protection and a longer service life, while OAT coolants use organic acids to inhibit corrosion. The yellow color of HOAT coolant signifies its blend of OAT and silicate additives, which is different from the red color of OAT coolant, which is a pure organic acid technology. " So now I'm back to thinking that the proper coolant is an OAT coolant, so basically the G30. And it's red/pink, so it makes sense with the color also (not a reliable identifier)
I found this: "GlycoShell is an OAT coolant. It's an organic acid technology coolant, meaning it uses organic acids to protect the engine from corrosion, rather than inorganic additives like silicates or phosphates. GlycoShell, specifically the "Longlife Concentrate" version, is designed for extended service intervals, potentially up to 4 years." And as we know, Glycoshell was the requirement in the owner's manual for a 360, 430 and the 458. The 488 calls for Carix, but it said somewhere that it is the direct replacement for the Glycoshell. where did you get info that the Glycoshell was a G48 fluid? I can't seem to find anything that points to that.
If you look a above in a previous post I found a website which notes this in the title, but I now understand the website is riddled with errors confusing everyone.
Yeah. I totally see how it’s confusing because I’m even confused, and I tried researching this at least three times in preparation for the upcoming coolant change that I want to do. I sent emails to the company that makes Carix coolant just to make sure it doesn’t have any silicates in it, and to also ask if it’s considered a G 30. Maybe we will get lucky and get a straight answer from the manufacturer themselves instead of speculating with everything we are reading that is contradictory. so as of now, what is the bottom line, can we safely say that G 30 is the proper coolant for our car?
You're safe with G30 nitrite free. My dealer recommended Shell Rotella. To add more confusion to antifreeze selection I called Shell. They recommend staying with the manufacturer recommendation and suggested Shell Zone. I asked about Shell Rotella because my dealer is using it. My dealer said it is a G30 classified antifreeze. Shell said Rotella is not classified in a G?? class. Instead Shell said it meets ASTM B6210 standards. When I change my coolant I will be going with Shell Rotella ELC NF after doing a flush.
