Best oil for tired Engines???

Recommended Posts

johnb110
To expand our oil debate a bit... What IYO is the best oil to use in a tired old stinky oil burner that you don't have the time to rebuild in the middle of mowing or blowing season. Also has anyone ever had any success in just doing a ring job without a complete rebuild??? John... who just mowed a over the hood septic system with an old smoker in my Sovereign , just awesome a newer 16 IC Briggs couldn't even get in 2 ft. without stalling.

Straight 30 weight Mobil Delvac,the million mile diesel oil .It is not suppose to be used in passenger cars because the zinc content is so high it would melt your catalytic converter in 30 seconds.Your tractor will use no oil and if the rings are gummed after a few oil changes it will free them up.

For what's it's worth, I remember reading literature somewhere, that Delvac and Rotella should'nt be used in engines without roller lifters. Something to do with the scuff agents and how it could wipe out the lifters and cam.

When I worked at a heavy equipment dealer,I picked up some Komatsu 15W-40 oil. I use it in my 712 with a tired Kohler.It burns it less than the straight 30 Pennzoil I use in the rest of 'em.

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
