Really...I've been duped !!! Fell for the " synthetic " on the bottle. Had no idea DOT 3 or 4 was ALL synthetic. Learn something new everyday. Thanks for the heads up

...I normally use Lucas " Synthetic" brake fluid. Seems to be the clearest looking fluid I've found. Guess it's just more refined to make it clearer ????? I dunno....Now, I'll go back to plain ole Johnsen's Dot 3 fluid in a gallon jug. Cheap stuff, but I do a lot of brake jobs, so it won't just sit there opened attracting moisture. Thank you so much for that info
