i have a Datsun Cherry 100A F-II 1974, and recently my stupid mechanic put some weird brake oil in it. now its almost finished and my brakes are not working due to that, i bought a guard company brake oil but my mechanic said that you cant mix 2 oils together or your brakes cylinder will be damaged by chemical reactions.
the problem is that i want to put guard company brake oil in it then how should i get rid of that stupid brake oil in my car? without getting any khuari.
urgent!
