When you do top off any low cooling system though, always use undiluted antifreeze. Unless you’re adding a significant amount to top it off of course, then you should probably try to find out why it was so low.

Once again, I'm hard of understanding.
In the shelf I see 2 strengths of most brands/types. The 1 is marked "ready to use". The other should be mixed 50/50 with distilled water. Looking at the price, I get paid pretty good to mix it myself. The concentrate will freeze at higher temp than the proper mix, plus it is a waste of money to use it straight.
