No comparison of Redline to Quaker State would be complete without this....
Your shiny new Ram has a oil pump failure, or a bad rod bearing or a thousand other oil related issue that can happen even with great oil. Dealer asks for your OCI records and you whoop out those receipts and they take one look at the word Redline or Quaker State guess who is about to have a bad day? The Redline guy! You say BS it wont matter, no sir it does go find the topic that I posted 4 or 5 weeks ago about the guy whose warranty was denied because he could not prove he ran a oil that carried the required ratings by Chrysler, Redline has none of the required ratings for what ever reason they have no API or MS6395 so use of it in the Ram is grounds for warranty deniability. You scoff and say the Mag. act will protect me ! many thousands of dollars in lawyers fees later, much more than the cost of the repair your fate will be decided by a judge. So what about the guy using Quaker State.... He shows them his receipts and they pull his truck in the service center and replace his motor. So run what you want to, like every thing in life choices come with consequences.
