Power steering fluid in fuel
 

Has anyone heard of filling up the fuel canister with powersteering fluid when changing out the fuel filter?

:nope:

power steering no

ATF yes

couldn't see why

ATF no !

You fill a fuel canister with FUEL - nothing else. ATF is not meant to be burned.

A while ago a driver had us fill his new fuel filters with atf during an oil change on his peterbilt. Seemed to work ok, he claimed it added lube.

"ATF is not meant to be burned" I keep seeing that and variations on that in various threads. Well that's true, but Dresden wasn't designed to be burned, either. That lit up ok.:w2:

That's a stupid and careless comparison with no respect for the victims of war which lost their live.
The city of Dresden was jam packed with refugees during the air raid.
300.000 refugees burned in Dresden instead the estimated 30.000 residents.

Now back to ATF:

- Different flame points
Diesel will burn sooner and longer than ATF. That translates in a longer, forceful piston downstroke with diesel than ATF

The claimed reduction in EGT's is true. Less BTU's- less burn time equals into less heat. Less heat equals into lower EGT's.

- Hydrocarbon deposits will be left
Since ATF is not designed to be burned ATF does not vaporize as good as diesel. This is dangerous for high pressure pumps like Common Rail or VP IP's since pressure shafts are known to break. CP3 pumps and piezo injectors are sensitive and costly devices.

- ATF is formulated completely different.
It contains a high level of detergent. Designed to transport and to encapsule contaminants. But do you remember? ATF does need operating temperatures of 176°F and above to work. It causes wear via abrasion below this temperature...
ATF does not consist any lubrication properties against shear forces- a good lube, huh?

Come on,
running ATF because you are not able to see the bad does not mean it is good for your engine.

Trusting a hillbilly mechanic does not really show any educated point of view.
It might be good or might not be good. But-physical and chemical facts are simply against it.

Wow...what won't people throw in fuel.

It is basically light hydraulic oil...it will burn but don't expect it to help anything.

The additives in atf are very hard on the tight tolerances of the modern day injection pump. Hey its your truck i could care less what you put in the tank.

Sorry Dieselstinkr, I used the first example of a well known fire of something that wasn't intended to burn that I could think of. Didn't mean disrespect, any example I give is bound to piss off somebody.

Anyway, the fact that something isn't designed to burn means pretty much squat when it's injected under high pressue into a combustion chamber preheated by compression. You guys finally came up with some good reasons not to put atf in the fuel system.

I understand and it is no problem to me.:tu:
