Antifreeze Pentosin or OEM Volkswagen

O'reilly around me carries the correct G12. Brand is Pentosin.

I got the light this morning on the wife's JSW. So I checked out the situation. Sure enough seriously low coolant, like well below minimum fill line. Only 7000 miles. Took it to the dealership to have it topped off.

this is the proper coolant, and the best option out there....Ive used Pentosin G11 blue forever....

VW G12 and Pentosin G001200 are the same thing, both are pink/violet in color, phostphate, nitrite, and amine free. You should not mix cheapy prestone / o'reilys with the G12, it may turn the coolant to a sludgy substance and clog the system. Basically solidifies when mixed with other coolants. Also may build up rust or other small deposits through your cooling system.

for vw's; i prefer using the 50/50 coolant from the dealer my gf's 2.0 had a small leak for months and we just kept on topping it off with the pepboys stuff-- but once i replaced the thermostat housing you can see corrosion in the hoses and the old housing -the coolant from vw is quite different than aftermarket brands (you can really tell just from its thickness-- i suggest forking the dough over for the vw stuff -other cars; i don't know

G12 may cost 12 bucks a gallon, but you only need one gallon and the manual states it is good for the life of your vehicle.

i run the G12 - every vw i ran G11 in, the coolant broke down after 5k miles, but the minute i swiched to g12, i have yet to have a problem

The mk3 came with G11 coolant. The mk4 came with G12 coolant. I'm running G12 in a well-flushed mk3 radiator, and I have no problems.

Regarding genuine VW antifreeze and generic...from what I understand, anitfreeze like Prestone is phosphate free but the real VW antifreeze (Pentosin) also has protectants for the plastic parts of the system, etc. The genuine stuff really isn't that expensive from the dealer.
