Ran this oil in our Armada we acquired this summer from a family member. Had bulk 5W30 most of its life with 5-7k OCIs. Got this oil a few months ago when it was $2/quart at RK. Lead is a little high, thoughts? During this OCI there was about 1k miles of towing. Mostly my 16ft tandem trailer with mower and gear, but also a few hundred miles of towing a 25ft travel trailer. Thanks!
