Pentosin Pentofrost
I use the blue antifreeze (G11) that was specified for my 1987 16V. I am currently running 10W40 synthetic oil.
I use Prestone 50/50 HOAT compatible in my 2012 JK and it works great. I like to do it every 3 yrs or so.
I use Pentofrost (Pentosin is the OEM supplier to Porsche). Our local NAPA carries it even.
Prestone Max Violet is ok to use--it meets G12++ or TL774G which is fine to use with the G12evo in your car already.
I always use Prestone concentrate and then dilute it down to a 40/60 coolant to water ratio.
Pentosin is one of my trusted brands. I would not hesitate to use it.
Prestone is designed to be compatible with the Toyota Red coolant, which is also POAT. Should be fine.
Most likely answer is he used one similar to PRESTONE which they do have one thats for all makes and models, it is a universal coolant including European models.
I’ve done it with my fiesta that had a leaking thermal housing I think I ended up topping it up so much by the end it was almost all Prestone wouldn’t personally do it on a car I care about though
