I found this out last week when I was trying to plan ahead for the big blinker fluid change this weekend, and when I read the label, I was pretty steamed. Looking at Google Trends, which tracks back to 2004, searches for blinker fluid on Google started to rise in 2016 and hit their peak in April 2017.

The joke has been around for a number of years. These pranks are generally played by the experienced group on a novice and often send that person off on an impossible search. Your best shot at preserving these cars for the long haul is to continue servicing with a fluid that's certified BF-005.05! The search for blinker fluid is part of a bigger class of jokes called fool’s errands. We're supposed to junk them and lease a brand new one. But we all know that BMW doesn't want us driving these cars after 5 years.

It's too bad BMW picked such a shitty coating on their races. And that's the number-one cause of premature blinker bearing wear, and as I'm sure you all know, the replacement BMW blinker bearings are like $800 for rebuilt ones, even on eBay!Īnd then even the rebuilt BMW blinker bearings don't really last more than 20,000 miles once the races have been depleted of their ionic coating. I don't know if this was a change in the formula or what, but you're definitely taking a big risk with this brand, because any Blinker Fluid that does not meet this spec, does not have the required stochiastic blend of long-chain monomer thiolates that prevent the electron-drift in the blinker's cathode. I hate to be the bearer of bad news, guys, but if you go to the store and look at a bottle of KaleCo Synthetic, it no longer says that it meets the BMW BF-005.05 specification.
