bhanxx Posted September 15, 2003 Share Posted September 15, 2003 I'm getting ready to change mine at the 16k and seriously considering doing 5.1, but have never used it b4. What r most of used guys doing? What r the important points to consider? I have a Mighty Vac and don't want to empty the systems, but pull the new stuff in right behind the old as I pump the old out.

SwampNut Posted September 15, 2003 Share Posted September 15, 2003 5.1 stays cleaner longer. Higher boiling point. All good. Unless you're breaking the system open for some reason, just pump through new fluid. No need to vac it. Quote Link to comment Share on other sites More sharing options...
bhanxx Posted September 15, 2003 Author Share Posted September 15, 2003 Thanks. I'm just replacing the fluid to keep it fresh'n'new. I'll just pull the new stuff thru as i pump out the old. Quote Link to comment Share on other sites More sharing options...
Northman Posted September 16, 2003 Share Posted September 16, 2003 The MityVac will be quicker and cleaner than pumping & bleeding, IMHO. Just be sure to bleed the system when you're done swapping the fluids. FYI, I've been using Motul RBF600 racing fluid, with good results, cause the 5.1 seems to be hard to come by around here.

XX RATED Posted September 16, 2003 Share Posted September 16, 2003 Seems to me that I read a thread on this forum a while back regarding the use of silicone based fluids with the stock seals. Is the 5.1 silicone like the 5.0; or have modifications been done to allow for use in the stock system? Quote Link to comment Share on other sites More sharing options...
Northman Posted September 16, 2003 Share Posted September 16, 2003 No, only the 5.0 is silicone based. The 5.1 can be used in any DOT 3 or 4 system, with no ill effects. DO NOT MIX 5.0 IN ANY OTHER SYSTEM! Quote Link to comment Share on other sites More sharing options...
EVLXX Posted September 16, 2003 Share Posted September 16, 2003 Can you tell me why I can't use 5.0 in my current system even if I evacuate the whole system first? Seems to me it would be a much better product or at least paint friendly. Quote Link to comment Share on other sites More sharing options...
Hokie Posted September 16, 2003 Share Posted September 16, 2003 Can you tell me why I can't use 5.0 in my current system even if I evacuate the whole system first? Seems to me it would be a much better product or at least paint friendly. If your system was made for non 5.0 fluid 5.0 will ruin it. Even if you evacuate the whole system there will still be left over fluid. 5.0 and 5.1 do not mix, also I think 5.0 will eat the seals in a 5.1 compatible system. Note: 5.1 is compatible with DOT 3 and 4. Quote Link to comment Share on other sites More sharing options...
