Who the heck reads the owners manual???
DOT stands for "department of transportation"....and the different numbers are for thier boiling points and a few other properties of brake fluids.5 is synthetic hi temp brake fluid.
Mineral oil is...well, basically the baby oil your mom put on your bottom....and not approved by the DOT for use in brakes....I'm not sure about thier stance on baby's bottoms....probably some other dept here in the States.
The main reasons mfgrs use it is:
it's Cheap....really Cheap
it's biodegradeable...so stoarge is simple,no problems working with it, and if it leaks...nothing gets harmed and maybe a few babies bottoms will get lubed.And if some dumb consumer consumes it...nothing will happen and the mfgr won't get sued.
And did I mention it's Cheap...really cheap?
It's bad points:
It's cheap, really cheap.
It doesn't handle heat well.
It breaks down and contaminates easily.
Although you can drink it, it tastes really bad (don't ask)
As for it getting into your tranny...well, it's a small amount, it's slippery stuff.....and considering there's always a little dirt and water in there...it's the least of your worries. Ater all, you should be changing the tranny oil frequently anyway.
And if you use atf in your clutch lever...and in your tranny, what's the difference?
And if you want to play Mr.Science....warm up some ATF, squirt in a little brake fluid...and put in in the blender. It will mix in quite nicely...which is what will happen in your tranny.
And if you read almost any can of motor oil, brake fluid or atf...there is usually a little marketing blurb about the products ability to swell seals...
Ok...enough about hydro clutches.
Who knows anything about little GAssers?????
