Pentosin Pentofrost
Reviews of Pentosin parts For Business
Germany
I use the blue antifreeze (G11) that was specified for my 1987 16V. I am currently running 10W40 synthetic oil.
I use Pentofrost (Pentosin is the OEM supplier to Porsche). Our local NAPA carries it even.
I use Pentosin Pento HP II fully synthetic Euro Spec 5w-40 oil (made by Fuchs Oil in Germany). According to test data I have read it is a much better oil than the Mobil 1 oil. I believe that the 5w-40 oil provides greater protection against oil vaporization, as the OM642 can run at elevated temperatures leading to high oil temperatures, which tends to break down the oil sooner.
Pentosin is one of my trusted brands. I would not hesitate to use it.
I've used pentosin E for full flushes of two Golfs (2015 and 2017). No issues. Prior to that, I used it for topping off. It's the right stuf being G13 regardless of slight color variation pink/purple.
I’ve used Pentosin Pentofrost NF, it’s the same as OEM
After talking to a European mechanic. He said u need Germany oil for a German car. American oil is trash bc of the EPA regulations. He recommended Pentosin. The tick tock went away and I've been using it every oil change
Use pentosin
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
