Antifreeze Pentosin or OEM Toyota

It is best to use the genuine BMW coolant, but in an emergency Pentosin NF antifreeze is apparently compatible with the OE coolant in your BMW.

I did this a few weeks ago on my '13 Sequoia, but I did not flush it. Just drained the rad and the valves on the block. Replaced with Toyota red and distilled water at 50/50. The fluid I drained was as clear as the fluid I replaced, so I felt flushing was not necessary.

Ditto. I only use G11, made by Pentosin.

I believe Pentosin Pentofrost A3 is equivalent and it's also $19 from Advance Auto. I have both at home because the Pentosin is equivalent to Subaru coolant as well.

I'm almost positive that VW uses Pentosin at the factory- I think the G12/G13 is the same stuff as the Pentofrost SF/Pentofrost E.

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.

Toyota brand coolant is top notch, supposedly can last for the entire life of a car and never needs to be replaced

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.
