Antifreeze Pentosin or Prestone

G12/13 has better lubricating properties over long periods of time, which is why they use it in what you always hear as "lifetime fill." This is due to the phosphates in the coolant.

The Prestone stuff works just fine and there shouldn't really be an issue.

I use it in my Audi, VW and KTM Adventure without any problems.

Use the specified coolant I would use the specified coolant for the vehicle in which you drive and always use distilled/deionized water foreign or domestic! The cuts down on deposits and electrolysis from corrosion from using tap/ground water and or the incorrect coolant.

I have been using Prestone Green FORever, in all my cars but the one that is Dexi-cool. I don't think I have ever had an issue with the Green as I flush my cars on a bi-yearly kinda thing or when I have to change things.

Do not, under any circumstances, mix generic auto store coolant with G12/13. If you are low, top it up with water - distilled preferably.

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

I use Prestone Celisus Anti-freeze/coolant. It's pretty much universal, never had a problem in my 92 TD or my 91 1.8 8V with coolant or overheating.

Volkswagen G12 coolant - ~$20/gallon Prestone Extended Life coolant - ~$8/gallon Distilled water (preferably reverse-osmosis/deionized water)

I used 3 of those Pentosin blue with a bottle of Water Wetter and the rest is water.. my temp is 30 degree higher than it was before and I don't know what the heck it was in there before which is this yellow/green milky stuff, it sure kept the engine mostly below 180. But now I hit 220-230 easily
