Nothing. They are compatible. Except for, is it Dot 4? Only use in systems that are designed for it, which they are not.

I'm sure someone else will have something else to say about it. I would not be changing type any ways. But you always flush the system till the clean/fresh fluid comes through.

Dot 3 and 4 are compatible.  Dot 5 is not.   Dot 5.1 is but might not work correctly in our brakes, it is designed for ABS systems which require a different viscosity than Dot 3 and 4.
our bikes are required to have DOT 4 and come that way from the factory.
always use the highest wet boiling point in a dot 4 one can find. higher wet resists water contamination longer allowing 3-4 yrs before replacement. Dry boiling point is a concern for road race track usage, no need to worry about it for street use bike.

Been running #4 in both my bikes. No problems. Don't think I have ever owned a bike that had anything other than #4.

Checked my service manual......   "Use only Dot 4" .

Technically, it is ALL synthetic. There is no 'natural' source of the chemicals that comprise brake fluid.

I would say read the bottle. If it doesn't say it specificly compatable, then I wouldn't chance it.

I'm looking for anti freeze, and don't want to buy the $50 a gal type from the MC shop. My shop of choice doesn't even have aluminum block/rads, or silicate free type anti freeze.

Granted, this was provided by a competitor, but it does show how difficult it can be to convert to this:

Look at the cap on your reservoir or you manual.

Thanks for the site. I've had the evans installed for over 30k , never had a problem. I have a temp gauge, only see a slight temp increase. I have a dyna ignition and I have had to shut off the 10 degree advance sooner at lower rpms than before the install, it was only a few 100 rpms. its a balancing act. more heat makes more power and mpg balanced with too much and no knock, however there is no steam pockets made in the head. evans stated on their site the less heat transfer of their product compared to water, nothing is better than water except maybe some exotic $$$ chemical. I do get great mpg along with other mods done.
I will look into the site/product more, could always be something better.

We're kind of guilty of a thread hijack, but I dislike the difficulty and cost to convert, more than the higher temperatures; of lesser importance to me is the effects on aluminum. Our engines aren't trapped behind a lot of metal and plastic, so get a lot of cooling from other than the radiator, except in stop/go traffic, so I'm not surprised at your results, there.

I used to road race cars, buy the best brake fluid you can afford.

I ran Motul then I run Motul in all my bikes.  Just suck out the old and flush with the new, top off..


Motul RBF600 DOT 4 Brake Fluid 500 ml

Motul RBF 600 is a 100% synthetic fluid for hydraulic-actuated brake and clutch systems. Specificall
Motul RBF 600 far exceeds the standards of DOT 3 and DOT 4.
The RBF 600 container is filled with Nitrogen to increase shelf life and eliminate contamination whi
Extremely high dry and wet boiling points help prevent vapor lock and brake fade during hard use.
