I thought Ford changed their O-rings and lines to synthetic materials back in 94 or 96 to eliminate compatibility problems, with oil and fuel additives.
This is a quote from another site.
I've been driving diesels for a living since 74 and have learned many of the truckers bad habits. Many of which have to do with "non fuels" I always carried cans of ATF to refill fuel filters so I didnt have to prime the pump. Added gasoline to the fuel in the winter time to lower the at which the fuel would gel. One company I drove for had a fleet of about 1000 OTR trucks and one central maintenance shop, whey they did oil changes it all went into their underground fuel tank and when you fuel there you got black fuel. Another national leasing company (Ryder) pumped the oil from the pan, through a filter and right back into the saddle tanks. Im now on my 7th diesel 3 OTR trucks and 4 Pickups and they all got treated the same way. Now for the past 12 yrs I've been in a mixer so depending on what company I worked for and who I knew in the shop Ive had a pretty good supply of hydraulic fluid or motor oil. I never had any specific ratio I would use, just whatever I was given, and a lot of that was just filtered through an oil filter. I have a friend who used to work for the electric co here and he brought me two 55 gallon drums of transformer and I used a lot of that straight. Oil changes and ATF changes always went thru a filter and then into the tank. Ive been running on WVO for the past year and a half now so I dont look for others now but if something is offered I will burn it. A few months back I blew a hydraulic booster ram on the work truck and the mechanic had almost 20 gallons of hydraulic that was gonna go in the waste oil tank. I brought it home and mixed it with 60 gallons of wvo and settled and filtered it just like I would with veggie. Just over a year ago I pulled the injectors and replaced them with some stage I from Bean. There was a slight carbon buildup on the nozzles and nothing wrong with them internally. If all these non fuels are bad for injectors it sure was not obvious on mine.

It just seems if this guy can run all this stuff through his PSD, with no ill effects, a qt. of ATF now and again would't hurt a thing.
