Hi I have just bought a 350z and I am trying to find out what coolant/anti-freeze I can use in it. I can see that it needs to be either the Nissan L250 or L248 but that means going to the dealer. As the manual says you can use and equivalent but I can find nothing on here that suggests one. Is there anyone out there who can tell me what 'equivalent' they use or do you all just get it from Nissan? Sorry if there is an answer somewhere but I can't find it. Many thanks for the anticipated help...
