michaelgordon Posted January 17, 2019 Share Posted January 17, 2019 I have seen the big fluid list and was pricing up the motul rbf 600. I called Nissan to compare to their own super heavy duty and was told that they only use normal dot 4 in everything Inc 35p and 370. Only the gtr has a different fluid. I will not be on the track at all. Do I need the motul or could I use normal dot 5.1 as it's less than half the price. I'll be doing a full system drain and bleeding all the calipers and will also be doing the clutch. Quote Link to comment Share on other sites More sharing options...
Jack94 Posted January 17, 2019 Share Posted January 17, 2019 The only reason to use performance fluid is that it's got a higher boiling point, so if you you don't drive hard then regular Dot 4 will be absolutely fine. Also rather than draining the system you're better off keeping the reservoir topped up and pushing the old fluid through (either manually or with a pressure bleeder). That way you won't introduce loads of air into the system that you'll then have to get back out. Quote Link to comment Share on other sites More sharing options...
michaelgordon Posted January 17, 2019 Author Share Posted January 17, 2019 Thanks Jack. I drive spirited but no track, that's why I thought dot 5.1, higher than dot 4. That's what I meant proper bleeding not mixing fluids Quote Link to comment Share on other sites More sharing options...
Adrian@TORQEN Posted January 18, 2019 Share Posted January 18, 2019 Hi Michael, 2 bottles of StopTech 600 would be perfect, see here: https://www.torqen.uk/nissan/350z/brakes/fluid/2072-350z-stoptech-racing-str-600-brake-fluid-500ml-bottle-50100001.html Quote Link to comment Share on other sites More sharing options...
