No time paradox or ravenous space monkeys will ensue.

There may be a shift in the vortex  in your commode though.

Because of this, it is not advisable to leave any necessary bits within a close proximity of the operating medium.

Yes but what about Nazi  Zombie Robots ?

Note the following standard Quantum Physics disclaimers should be applied:

WARNING: This Product Warps Space and Time in Its Vicinity.

WARNING: This Product Attracts Every Other Piece of Matter in the Universe, Including the Products of Other Manufacturers, with a Force Proportional to the Product of the Masses and Inversely Proportional to the Distance Between Them.

CAUTION: The Mass of This Product Contains the Energy Equivalent of 85 Million Tons of TNT per Net Ounce of Weight.

HANDLE WITH EXTREME CARE: This Product Contains Minute Electrically Charged Particles Moving at Velocities in Excess of Five Hundred Million Miles Per Hour.

ADVISORY: There is an Extremely Small but Nonzero Chance That, Through a Process Know as "Tunneling," This Product May Spontaneously Disappear from Its Present Location and Reappear at Any Random Place in the Universe, Including Your Neighbor's Domicile. The Manufacturer Will Not Be Responsible for Any Damages or Inconvenience That May Result.

THIS IS A 100% MATTER PRODUCT: In the Unlikely Event That This Merchandise Should Contact Antimatter in Any Form, a Catastrophic Explosion Will Result.

NEW GRAND UNIFIED THEORY DISCLAIMER: The Manufacturer May Technically Be Entitled to Claim That This Product Is Ten-Dimensional. However, the Consumer Is Reminded That This Confers No Legal Rights Above and Beyond Those Applicable to Three-Dimensional Objects, Since the Seven New Dimensions Are "Rolled Up" into Such a Small "Area" That They Cannot Be Detected.

PLEASE NOTE: Some Quantum Physics Theories Suggest That When the Consumer Is Not Directly Observing This Product, It May Cease to Exist or Will Exist Only in a Vague and Undetermined State.

COMPONENT EQUIVALENCY NOTICE: The Subatomic Particles (Electrons, Protons, etc.) Comprising This Product Are Exactly the Same in Every Measurable Respect as Those Used in the Products of Other Manufacturers, and No Claim to the Contrary May Legitimately Be Expressed or Implied.

HEALTH WARNING: Care Should Be Taken When Lifting This Product, Since Its Mass, and Thus Its Weight, Is Dependent on Its Velocity Relative to the User.

IMPORTANT NOTICE TO PURCHASERS: The Entire Physical Universe, Including This Product, May One Day Collapse Back into an Infinitesimally Small Space. Should Another Universe Subsequently Re-emerge, the Existence of This Product in That Universe Cannot Be Guaranteed.

Ice, it's 5 that's silicone based:

"So now we have D.O.T. 3, 4, 5, and 5.1, with all but the 5 designation being glycol, while the 5 is silicone. "

In addition to flushing when changing types, you should disassemble the system, remove all rubber seals and soak them in alcohol to get rid of any traces of the old fluid.  Even so, the seals may not be compatible with the different type of fluid and may deteriorate.

As far as mixing compatible types, I don' know if there's a problem with that.  Usually I don't top off, since it's only a few dollars a bottle and you're supposed to use a freshly opened bottle, and it's only a few dollars, I just flush the system while I'm at it.  So I guess I'm never really mixing.

Not to self;
 Self, don't post technical stuff at a quarter till one in the morning after working a double shift.

Fixed.

I was in the garage and found an old container of DOT 5.1.  It said right on the label it mixes just fine with DOT 3 and DOT 4.
