Is that's what's sold at O'Reilly Auto Parts? If so, I used some 2-cycle oil of theirs in my weedeater...it was so corrosive or acidic that it ate through my fuel lines.

If this is for your diesel...stick with Shell Rotella T or Chevron Delo. If you buy it at Sam's or on sale somewhere like Wal-Mart by the gallon, it will be the same price as that Kendall stuff.
