This years super tech RV antifreeze of lesser quality?

Note too that it comes in different freeze ratings. My local big box had both -30 and -70 available. The -70 was 50 cents more, so I made the big investment in the two gallons I needed. (Well, actually 12 gallons - I have a pool that needs it, too!).

it was the same -50 from last year. I guess i should test it in the freezer and see how well it does.

No I cannot, but I will only use Blue DEF and pay the extra $4 per big jug from now on.

I use the blue def since the day i picked up my 2018. The extra few dollars more is peace of mind for me.
