Hi all, I’m almost out of coolant in my car, I had previously brought Comma Xstream G40 in late 2020 from Halfords as it was stated as compatible via their license plate search. I’ve looked at their website today and it says that my car is not compatible with that coolant. I’m now unsure if they is okay to use. It didn’t seem to cause too many issues when I used it last, but that time I was only topping up a little, whereas this time it would be a quite a bit. The tank in the car says it needs G13, I can’t seem to find out if the comma is G13. Does anyone have any experience with this? I don’t really want to drive the car before it is topped up as I drive on the motorway and the car started to beep and displayed a red light warning to check the coolant.
