Creaver 55 Report post Posted August 4, 2009 What is the difference with dot4 and dot5.1? Wikipedia says this: http://en.wikipedia.org/wiki/DOT_5.1 And I understand all that. But will it damage my current brake piping/hoses? Would you recommend using it in my car? etc Cheers, Ian. Quote Share this post Link to post Share on other sites
Mark 178 Report post Posted August 4, 2009 Shouldn't damage anything. DOT 5.1 can replace DOT 4 in any car I believe. I use it in the E30 and it hasn't caused any problems. Simply stops fluid boil when I take it to the track. Quote Share this post Link to post Share on other sites
