Auto trans fluid is a really good cleaning/de-carbon agent. I don't know the chemistry on this one. The NT 855 Cummins, a pre-computer era big diesel widely used in countless applications- was under the hood of the first semi's I drove as a greenhorn company driver. Every year or so the high-mileage engines would gradually have a small power loss, then begin running slightly uneven, and continue getting worse, one or more injector was not delivering correct fuel relative to the rest. The term used in the industry was "stuck injector". (I don't know if that's actually a correct diagnosis.) We were instructed by the company to add 1/2 to 1 gallon of auto trans fluid to the tank when fueling up, whenever this occurred. Over the course of burning off that tank (300 gallons), the engine cleared up and restored power- every time.

Great info Frank! Always love hearing the real life stories...reality...of what really works in the real world. Not something that A.I. created.

I want to say this info came from a Metallurgist's writings I read in the past....that once you get trans fluid on metal...it is extremely and near impossible to remove all traces of it from the pores of the metal. I've used it for years on rusty bolts...just letting it sit over night and usually I can break them free the next day. It doesn't eat off the rust like rust busters...but it penetrates the rust and the pores of the good metal. If I've got a real stubborn bolt...it's the O/A torch till it's dull red and then doused with a spray bottle of water. That....has never failed me yet.

I wonder if adding a small amount of trans fluid to a tank of gas would be a benefit? Can't see how it would hurt...too much would cause smoke.

Kenny on the u-tubes videos puts in a quart of ATF type F in
older engines with noisy lifters and it quiets them by cleaning out sludge.

He adds it to the engine oil...or the gas tank? ( I assume nothing ) Adding to the oil makes sense...I'll have to try it.
When I had my 91' Harley I'd add about a 1/2 ounce of acetone per tank..had a little more throttle response and didn't burn up the plugs.
I miss that bike...HARD times and had to sell her 🤒

For lifters that would be in the oil. In light of my good results on diesel injectors and the guy with lifters, I may try this on a 7.3 diesel that runs good except one lifter is stuck pumped up, holds the valve open. I was going to try Sea Foam in the oil but the trans fluid should be less of a shock to the internals.
