jandyb Posted April 7, 2013 Report Share Posted April 7, 2013 (edited) On my gassers cluth mc it says use mineral oil and on the brake it says use only DOT 4. Are these two different oils and if so why - puzzled. Dot 4 = Brake fluid Mineral oil = ehh.. oil.. This artikle on Wikipedia should explain the difference GasGas uses mineral oil in clutch pump because some fluid leaks into gear oil, and brake fluid ruins the gear oil and clutch plates. -Jan Edited April 7, 2013 by jandyb Quote Link to comment Share on other sites More sharing options...

jse Posted April 8, 2013 Report Share Posted April 8, 2013 On my gassers cluth mc it says use mineral oil and on the brake it says use only DOT 4. Are these two different oils and if so why - puzzled. The clutch M/C (with the green cover) takes a special low-viscosity mineral oil, not the stuff you buy in the drug stores. You can get it from your GasGas dealer or off-road bicycle shops often carry the special mineral oil used on mountain bike brake systems, Like Magura Blood or Royal Blood. Do NOT use Dot 3/4/5.1 in the clutch. You can also use Dot-5 (Silicone) in the clutch without changing the seals/o-rings if you completely flush all Dot-3/4/5.1 out beforehand. The Dot-5 will give a little smoother uptake due to it's lubricity properties and being slightly compressable. Dot-5 in brake systems will give a "spongy" feel to the pedal.
