Anybody using Mineral Oil as brake fluid.

[AviP]

I came across this alternative on the BMW Sport Touring Forum. Seemingly, BMW stated that they would be switching to mineral oil (in their motorcycles) since it never needed changing. Also it is backward compatible with existing brake systems. Here's a link. http://www.finishlineusa.com/products/break-fluid.htm

Any comments?

Motul RBF600 only, and they help sponsor Viper Days!

Interesting lateral thinking.........Citroen, Roll-Royce, Jaguar have used it. Dont think it would be compatible with our brake system seals.....also dont know about the boil point. I use it in my mountain bike brake system(magura), but then I havnt got 400+bhp and 3600lbs to stop.

3600lbs - have you've been gorging on the turkey and spuds again ?

Are you serious? Normal over the shelf mineral oil for brake fluid!?

AAAACCKKK!!!! Read the FinishLineUSA site carefully - they make bicycles, not motorcycles. The fluids are listed for bicycles!!!

If there is a BMW Motorcycle brake fluid using mineral oil, please link to that info.

Also, mineral oil is merely the type of base oil, not to be confused with the performance of the finished product. Several different additives will be incorporated to provide the complete brake fluid performance. Additives are not to be under-rated; they are what make mineral (base) oil engine oil formulations fairly close in most performance areas to synthetic (base) oil engine oil formulations.

I thought it was crap too. Here's the link though:

If you try this, I suggest you try a tree, brick wall or maybe J Lo's ass next for comparison's sake.

I just carry a 120 lb plow anchor and a parachute. I throw it out the window when I want to stop

I can see one advantage. When the brakes boil at the end of a straight, you can cook what every you hit. "many parts are eatable"

Actually, the mineral oil version has a pretty high boiling point of 550F, on par with other high performance brake fluids. I think the downside with a mineral oil is in the long run, high temperature oxidation would cause the fluid to thicken. The regular brake fluids made of polyglycol or ester base fluids, which are similar to antifreeze or synthetic engine oils and would be naturally more resistant. So a bicycle application makes sense, since it's low temperature and less toxic than auto brake fluid.
