Brake fluid into crank case

You read it right. I woke up the other morning, before my ride into work, I had to top off the oil (I did an oil change the night before).

Had a half open bottle of...rut roh, ATE blue comes out of the Honda oil bottle. I forgot to label it as 'old brake fluid' after I flushed my brakes.

About half a tequila shot got into the crank case. Hoping that mixing and draining would do the job, I warmed it up, rode a few miles, came back, did yet another oil change + filter.

And I plan on doing this 2 more times.

I've researched online, but I'm reading different stuff. Read somewhere that people do this to 'clean the gunk out'. Also read a thread where a guy with a TA put 2 qts of brake fluid into his car, and wrecked the motor.

I doubt anyone would have any 'experience' with this, but if they do, help me out. I believe I should be ok, but any hard info would be great.

Brake fluid is corrosive and can eat certain alloys.

You could try finding a shop that has a Bilstein Motor Flush machine and see if they can hook your bike up to it. Not sure how compatible that is with wet clutches though. Same thing for at home motor-flush-in-a-can stuff.

Half a shot only went in and you've changed the oil since. The % of brake fluid will now be tiny so highly unlikely to cause a issue.

For piece of mind you could do another change.

Brake fluid is probably no worse than that Rotella oil ............

OH naw u diddnt!!!! rottella ftw.... got a 04 CRF250X with probably over 1500 hrs on it running a hotter cam on a completly OEM top end minus 2 exhaust shims... intake shims are still original... and always ran rotella.


As per the OP tho.... ur fine, maybe 1 flush is necessary but tbh i woulda just ran it like you did a lil, then drained, changed the oil n filter n rode.

Yep, T6 in there now.

Buddy told me maybe I should get some cheap Valvoline moto oil next time around, then back to the T6.

Oh, and I've tried the Purolator oil filter. Ran it in a pinch on my 600RR and it was fine. First time on the 919, hopefully it'll trap the brake fluid. :/

I think that after re-changing your oil you will be safe, Shmoo. I dont think you should be overly worried. do another change after a hundred or two miles and there will be nothing of the brake fluid left in there.

Well, fire the engines! Spur this iron space-pony on!

Retrospectively I'd have put some cheap oil in for the first/second quick change then gone to the good stuff. You did the right thing mixing it and dumping it pronto - no point putting decent miles on it as it will be throughly mixed in the engine pretty quickly under load.

Though I had a good laugh and shook my head, it was a easy mistake to make. It would be a long post if I listed all the dumb thinks I've done in the workshop over the years and there are a few permanent scars on my hands to attest to 'accidents' that should have been avoided!

You are never too old to stop learning!

I was embarrassed to post it, lol. Hopefully everyone can learn from this, always label your trash bottles right away.

Yep, this site is great, I think a lot of members have a lot of experience, which I plan to leach from them.

At least you didn't put coolant in your brake lines.

Although I hear it really helps keeping your brakes from getting too hot on the track...

An honest mistake you learned from is nothing to be embarrassed about. It's not like you intentionally set out to trick yourself into using brake fluid in the engine. Good on you for posting it up as you can get some answers and help educate others about the importance of bottle labeling.

I actually have about 3 grades of Mobil 1 that I use in the bike, car, and truck. You always get that little bit left over when doing an oil change. I pour all of it together in a "collector" jug which is just an old bottle of Mobil 1 and i use it in my lawn mowers, weed wacker, snow thrower, air compressor and anything else that needs oil. Happens to be the same grade I put in the truck. Almost grabbed the oilshake bottle last time I changed the oil in that. Probably wouldn't do any harm in the truck, but auto grades have moly which I don't want in the bike.

I'll be labeling the bottle tonight.

Did you send the sprocket back, or put it on and rock that pink

Hey, we've all been there, done that, in one way or another. At least you weren't the guy who started a thread on how NOT to clean your chain while the motor is running (yes, he ran his hand through the sprocket, google it if you want pics). Oh, that wasn't here in WT, btw, I REALLY hope none of us starts one of those threads.

Personally, I do not believe in half measures when full measures are available but only a quarter is actually needed.
Eons ago I built an RD350 engine, as in 35 years ago.
A tip at the time to better retain the crank bearings was to use some Loctite on the outer race OD shell.
So I did.
But I used too much.
The excess migrated own and seized the crank wheels to the engine casing.
For some strange reason the engine would not kick over some weeks later when I went to start it.
In retrospect, the diagnostics were hilarious.
Undid the clutch to free the gearbox from the engine, then a big flex handle on the crank nut - no budge at all.
To say I felt moronic when I split the cases and discovered my folly, is, well, rather an understatement.
And it took HOURS to chisel and clean off all the Loctite.
Lesson learned, as in lesson Plus

Friends of mine did a similar joke at the first track event I put on at Barber.

It was staged, but still held up for a laugh or two after the fact.






I believe it was the 2nd year of the event I show up in the morning and start unloading & then I noticed that almost every single bike in the paddock seemed to have the same bright orange decals. On closer inspection:

You decided to change your oil. Im guessing you didnt see any of the pics on here on how to do that.
You drained your tranny, THEN put the tranny fluid INTO your Coolant?????"
