I changed antifreeze on a family member's vehicle yesterday, and I picked up a couple bottles of Peak conventional antifreeze. When I got to the point of adding the correct amount to ensure 50/50 mix, I noticed that the sides of the bottles didn't have any marked graduations. There are ribs formed into the bottle, but I had to guess where 1qt/2qt/etc were located.
From their website, it looks like all their products may be moving to this bottle. I can see where this shouldn't matter on 50/50 products, but for full strength products I think this was an oversight.
