Redline SI-1 shrinkflation?
 

I ran out of my supply of Redline SI-1 Fuel System cleaner bought quite a while ago a few weeks ago and without much thought ordered some more.

When I got the bottles today I thought something felt a bit "off"; the neck seemed more diminutive. To be sure they are the real product. I checked the label and it says "15 fl. oz.". I could have sworn the bottles previously were 16 fl. oz.. I get it, shrinkflation but sheesh it feels like every time I turn around someone's got their grubby hands in my pocket fishing for more.

If anyone has a supply of of Redline SI-1 bought ca. 2019/2020 I'd love to know if I'm misremembering that the size was 16. fl. oz.

I don't have any myself, but I found a 6 year old video on Youtube.
Same 15oz bottle.

Redline might have re-tooled the bottle to save money. Thinner plastic, different packaging supplier?

Thanks both. Yes the bottle is definitely thinner plastic.
