About to embark on changing my spark plugs on my 2010 K1300GT, (yes, I have the plug removal tool), what is the recommendation for antifreeze liquid to be used to replenish the system? Automotive grade okay w/ 50/50 mixture?, or use what BMW sells?. Someone told me to use 100% as it is aluminum heads?

The BMW stuff won't let you down. Its a premix I think so no guesswork.

Napa Pentofrost is a direct replacement for the bmw coolant and problem cheaper. I have used it in my k12 since new

Yup, the NAPA Pentofrost NF is the stuff to use. Pick up a jug of distilled water to make it a mix. If you do not live in Canada or near it you can even go to 40% antifreeze. Don't use de ionized water.

Not sure of those products, I use Penrite Blue 8yr 500,000km concentrate, made up 50/50 mix with distilled water. No probs. Temp bar hasn't gone past half and fan kicks in nice and early. You will need the vac tool to fill the system.

I used Porsche antifreeze 50/50 mix with distilled water. No issues.
