If you pay for someone to winterize your 2016, you must be crazy

Hopefully you aren't using ethylene glycol based pink RV antifreeze. That stuff is horrible for your motor.

There was a fantastic thread on Team Talk that took about 2 years to complete that analyzed what was best for a winterized block: dry block, EG AF, PG AF or car antifreeze.

The two best performers were PG AF and dry block. Car antifreeze is great too but not really environmentally safe. EG performed horribly and rusted the crap out of the test sample.

Do you have them mixed up? Ethylene glycol antifreeze is normally green and propylene glycol is normally pink.

Everything is backwards in Ohio

There are all different types and you can get some pink PG stuff. I have never seen green EG antifreeze though.

The most common prestone stuff you get is -50F and EG based.

The -100F starbrite stuff that I have used that is PG based is green.

I'm sure there is variation though. I'm curious about this green EG based AF. Where do you find that?

So does the manual suggest adding antifreeze anywhere?
Do you have a link to that article, would be interested in reading it. Was it focused on cast iron, aluminum or both?

I will need to read the manual again to confirm but IIRC, there is no mention of antifreeze. I asked the dealer and they add antifreeze but IMO not necessary
