My question is about the engine coolant for my 2008 xb. my coolant is a bit low and I would like to top it off.

I have recently topped off my vw golf with some pentofrost e. I have some left over, and was wondering if I could use this in my xb? the pentofrost site calls for A4 to be used? how different are these and can they be mixed? or should I just go get some A4?

thanks
