Although that top oil is being compared to our least expensive oil, it still isn't warranty compliant.... ours is. :shrug:
Also, we both know that if a warranty issue were to arise, the UOA would confirm that both Signature Series and Royal Purple base line 5W-30 were both within the scope of a pass. The warranty wouldn't be denied.
Therefore, this isn't a viable tactic in this conversation. Let's focus on money versus product.
