mixing two stroke oil in diesel

[Polly]

      i had two ford 1984 model diesel trucks the injection pumps would go bade on regular basis the o rings rubber would harden and start chipping off i thought they had fixed problem apparently not

 I thought it was a non issue too, when I got my first load of ulsd I asked my dealer if it was going to be ok for older engines. They said no problem and I didn't need any additives. I still added the Power Stroke. Now y'all got me wondering? What about a 2 stroke detroit engine?

? What about a 2 stroke detroit engine?

Are there any around anymore? I figure unless somebody has one in a greyhound conversion that they are all long gone.

  out of curosity i wonder what all did use the two stroke detroit i took a course on their design back in late 1950s but not their application

Polly, I have a 353 Detroit in my Tree Farmer forwarder, date unkown. The Detroit series 53 service manual that I have is dated 1985 and the oldest section is dated 1971. Besides forewarders I don't know what else they were used in. But there are Detroit fans on here who will jump in and let us know.

They where common in large boats and off road tractors up until 1998 or so. They phased them out of on road vehicles in the early 80s. They where prone to "Running Away" and when it happened they could not be shut down and the engines would blowup.
