Antifreeze Pentosin or OEM Honda

I only use honda coolant. My 2003 crv has almost 300k on the original water pump.

Pentosin Pentofrost

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.

Use the OEM honda stuff. It's really nice.

I'm running Honda type 2 coolant in my 94 sonoma. Flushing helped but it seems getting a good P-HOAT coolant stopped or at least paused the rusting while offering better protection.

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.

You want the very best you gotta go Honda blue.

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
