On Havolines website they list under the why Havoline tab various API SN qualification tests (listed below) and in a nice turn of honesty they list by what % they meet or exceed the standard API base. I just feel this is refreshingly honest and gives you a real idea of what you can expect instead of the typical stupid "nothing works better" statement that everyone always uses that's so meaningless. What's my point just giving props to Havoline for what I feel is a solid statement of performance and I wanted to share with anyone who hasn't seen it.
