Re: Catch Can
Navy1 may be correct with the additives keeping things clear. Perhaps one of the oil and gas gurus could chime in here.
jeepster23 is correct, many report dumping several ozs of gunk outta their catch cans at 3-4k miles. maybe more if you have a heavy foot or are trail blasting.
regardless, these engines are running well without a CC. the shudder really looks like a drivetrain issue that jeep needs to get sorted.
