ATF Fluid in fuel tank

[Mattpm07]

While growing up I always remember my dad always putting a quart of auto tranny fluid in his 6.2 diesel fuel tank when he filled up. He said a trucker told him to do it because it keeps the fuel system clean. Is this true? I'm currently looking for a duramax and was wondering what's best to run through to keep the fuel system+injectors running nicely? Has anybody else done this or just me?

You can do it, it's not going to hurt anything. Supposed to add lubrication. I would just use a good Stanadyne fuel system cleaner with each fill up.

....powerservice or stanadyne lubricity....

X3 stanadyne is the only GM approved additive (not that it’s the best) so don't telling them you use anything different.
