I have a 2015 Chevy Sonic that , I believe requires DOT 4 brake fluid . Is that a synthetic ?
I also have a 1991 Chevy Caprice 5.0l that I have probably , most recently , used DOT 3 .
Is DOT 4 backwards comparable & OK to use in the Caprice ? I would rather have to have only one spec of brake fluid on hand .
Thanks ,
Wyr
God bless
