http://www.pennzoil.com/warranty/warranty.html http://www.quakerstate.com/pages/programs/warranty.asp ...Just curious as to what you guys think of this. Here's the questions I pose: I only see three exceptions to the rule: 1. Your vehicle doesn't meet the eligibility requirements. 2. You keep your vehicles longer than 10 yrs. 3. You keep your vehicles longer than 250,000 miles. Otherwise: 1. Why should you consider anything else (besides picking something else just for fun...)?
