Re: Changing fluids
Because I love you Tom:
DRY:580F -- WET:410F -- $/qt~$36.27 -- AMSOIL SERIES 600
DRY:590F -- WET:410F -- $/qt~$39.67 -- AP RACING 600
DRY:593F -- WET:420F -- $/qt~$27.99 -- MOTUL RBF600
DRY:610F -- WET:421F -- $/qt~$49.98 -- NEO SUPER DOT 610
DRY:620F -- WET:425F -- $/qt~$??.?? -- COBALT SUPER XRF
DRY:590F -- WET:518F -- $/qt~$60.58 -- CASTROL SRF
These are the "best of the best" brake fluids. I sorted them by wet boiling point. This is what matters after 2ish years of use when the fluid has absorbed some water. What is hard to find is thermal conductivity, heat capacity, water solubility and thermal coefficient of expansion. Most supplier only list dry and wet boiling point. However, I know Motul and Amsoil are fully aware of the benefits of esters in terms of being able to remove heat from metal surfaces.
I would say the Castrol is the best but the Motul might be the best buy of the bunch. I would go with the Motul over the Amsoil. Look on Amazon for it.
In contrast, Valvoline (a popular, easy to find, inexpensive choice) has a dry boiling point of 480F and a wet boiling point of 311F.
