I just read the website for Glysantin. Seems that it is ethylene glycol with additives to prevent rust,etc. That's what Prestone and all the other brands contain. Same stuff, but a lot cheaper. If you want to use MB brand,so be it. You probably buy MB batteries and MB brake pads. I use ATE pads and don't have to pay for the MB logo.
