Putting transmission fluid in your fuel?

[str8razor]

I have a mechanic friend of mine who said to add about a half gallon of transmission fuid to each fuel tank to clean the injectors and then from then on add a quart to each tank for every fill up to lubricate the injector o-rings. He claims it has something to do with diesel no longer having the sulphur in it and the injector o-rings will dry out and crack and begin leaking. Has anyone ever heard of this before and if so, does it work? BTW: I have a 96 F-250 7.3L turbo diesel.

Thanks!

Ive head of it and there are a bunch of threads on it about that on here. Personally I stick with the products made for it, dieselkleen

I've been adding a witches brew mix of outboard motor oil and diesel kleen. Things have been running fine in the cold up here so far. The outboard oil is TC-3W from Wallyworld.

Adding ATF to your diesel fuel is an "old school" way of cleaning the injectors, but a half gallon?!?! Your engine is a little more sophisticated than the engines your mechanic is thinking about. I'd stay with recognized fuel additives like Stanadyne.

Hehe....those ol boys are yakin about running their tractors. Stanadyne is good stuff. I just can't find any locally so the 'brew' will have to do.

When I say a half gallon, he was saying just for the first time to do a drastic cleaning then mantain it with a quart for every fill up.

My main concern is what he was saying about having to run something for the purpose of keeping the o-rings from drying out and cracking.

I run Stanadyne in mine, but regardless whether add something or not, there are only two O-rings that could possibly be affected by an additive. Many people never add anything to their fuel, and the O-rings don't dry out and crack.

I'm wondering if anti-gelling fluid can wreck orings now?

keep in mind too, not that it relates, but sulpher did not lubricate or help anything.
The process or removing the sulpher also removes the lubricationg qualities in the fuel. The sulpher did not lubricate.
