Has anyone heard of adding a bit of transmission fluid into the engine oil?
I've been told this could help with softening some of the seals inside and help clean out the engine.

Let me know what you guys think.

 

Keep the engine oil in the engine.

Keep the transmission fluid in the transmission.

 

I don't know about you, but experimenting & mixing fluids with 2 very important & expensive components based on something you "heard" sounds risky.

The way I see it, engine oil is already formulated to cleanse your engine components.

 

Meh. Don't do it.

 

A long time ago, transmission fluid was used to "flush" an engine because it is basically 10 weight oil.

Nowadays, modern oils have way more cleaning detergents. This is not recommended or necessary.

 

meh.. i do it to my miata but not often. like.. i'll throw in a little to bring my oil level up and do a lap around my neighborhood before I do my oil change but not every oil change.

 

sounds highly risky with variable reward... I'd steer clear of this one.

 

I trust you. You're the engineer.

 

ya damn right!

 

I've put blinker fluid in the crankcase. Got like 30hp gain.

 

BRUHH!!! YOU TOO?? i was trying to keep it a secret but since you let the cat out of the bag, this is the brand I use:

 

^ Have you tried their new synthetic fluid? Holy cow it's awesome and I can go twice as long without changing it now...

 

You should ask Rockyboy

 

Would this clean up the carbon deposit in my Avant?

 

Ive used trans fluid to wipe down and oil the cyl walls while building an engine to keep it lubed and protected during a build, but i wouldnt mix the 2 for driving. And what seals could possibly "Need" to be softened inside the engine? Hint...... NONE. Stick with a quality oil/syn oil and you will be fine.

 

^ Werd. A good synthetic will soften seals without over doing them, although I remember hearing back in the day that a car with a lot of miles on it that's only had dino oil it's whole life could possibly be harmed by using full synthetic since it'll soften the seals too much causing leaks..

 

Yes it will. Pour the entire bottle into your windshield washer reservoir and top with a 50/50 mix of lacquer thinner and distilled water, then proceed to drive it like you stole it. Should clean out the carbon deposits and give you a few extra ponies under the hood.

 

So excited! YES!

 

Oh man.. I've heard only legends of the synthetic blinker fluid... I've tried finding it at local stores but have yet to discover them..


I do a 50/50 mix of blinker fluid and dawn soap to clean up the carbon deposits.

don't listen to this guy, he's trying to ruin your car.. you don't put blinker fluid in the windshield washer reservoir... I put this in my resevoir, I heard it's very effective at cleaning the windshield

 

Hey, if it cleans injectors and valves, just think of how well it will get rid of those stubborn stuck on bug splats!

 

eats windshield.. problem solved.

 

I put 710 liquid in my engine

 

You can use ATF in an engine for it's detergent properties for a very short duration. Typically it's used in engines that haven't been turned over for a while to help make sure nothing goes wrong when it's cranked by hand a few times to make sure it's all good.
