And like most oil companies that give warranties on engines, there are about a dozen ways they can deny any claim you submit in the event something goes wrong. It is a great marketing tool to sell more oil, but it is mostly just that as the great number of claims will be denied. I know that in the fine print they often use ridiculously short OCIs as a condition for the warranty, much shorter than the vehicle manufacturer. For instance when Valvoline rolled out their 300,000 mile warranty for SynPower, they wanted something like 3k mile OCI's while Toyota tells me to go 5k.
