Review on Antifreeze Nissan L248 Premix 1 l by Boyan Donchev ᠌

From the factory (Vsevolzhsk), blue antifreeze is poured into the car’s cooling system, and filled according to the L255 passport, any dealer will tell you that blue is mixed with green, that 255 and 248 are the same thing, only the color is different, and this is absolutely true, but Nissan antifreeze, despite its color, is original and has no analogues from third-party manufacturers in nature, Texaco made this antifreeze for Nissan, and it received the name "Specification L-250". She has no direct analogues. As a general rule, and I have had Nissans since 1995, if you change the antifreeze prescribed by Nissan, and today it is L255 according to the regulations proposed by Nissan (term / mileage), then the internal combustion engine will have no problems with either the thermostat, or the pump, or heat exchangers ( radiator, stove) (well, except for external corrosion of the aluminum radiator from the environment), or with pipes and other things. Generally never in the foreseeable periods of operation! The Nissan L250 is free of silicates, borates, nitrites, amines, 2-EHA free, but contains some phosphates and, of course, other know-how ingredients. At the same time, it is painted in bluish (L250, 255) and green colors (L248). This is Nissan's decision. And it has nothing to do with other blue and green antifreezes. If for some reason you add L248 to a system filled with diluted L255, then the antifreeze replacement period will be reduced to L248 requirements - 3 years or 60 thousand km, unlike L250, L255 which have 6 years or 90 thousand km. mileage during secondary filling into the system. Antifreeze brand "L248" has a freezing point of up to -38 ° C, does not contain ethyl alcohol, unlike L250 and L255. This antifreeze is based on ethylene glycol + water and an additive package. pH "Nissan Coolant L248" in the region of 7.9. In terms of operation, there is no difference between L248 and L255 branded antifreezes, but due to a less enriched and “balanced” additive package, it ages somewhat faster than L255.
