New to me 2004 Wrangler TJ with 4.0. 105,000 miles and well taken care of; would like to keep it that way.
Thinking either regular Pennzoil 10w30 or Rotella T5 10w30.
Does the Rotella still have the ZDDP that I see recommended?
Would the ZDDP harm catalytic converter?
I'm a big fan of Rotella T 15w40 and run it in all of my motorcycles.
Thoughts?
