see im sort of suprised because its millers, i didnt think theyd be the sort of company to come out with guff like that

id expect it might make a power increase, but maybe for that one dyno run

Any oil change would recover some lost HP, but not that much

Unfortunately I don't have an RR installed in the driveway, but I've changed oil from black tar before and the power delivery difference 'felt' like pulling a sock out of the throttle body it was that much of a marked difference. You could feel the oil slowing the lump down. That was the worst state of engine oil I've come across though.
