Change oil = More performance!

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
 
We questioned the results on the ST forum, the owner said it did make a slight difference, but certainly he didn't feel that it was that much.
 
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.
 
Cars can sometimes make more HP on higher mileage oil due to viscosity loss. What a load of ****

So it's safe to assume that jb racings dyno doesn't work right ?

Peddlers of tripe like this should be shot
 
I drained as what can only be described as tar out of my girlfriends Ka, filled with Ford Spec Castrol 5w-30. Made **** all difference, still slow as ****. :D
