I certainly notice a difference. Was running normal Diesel for 2.5 years, now using Diesel Ultimate (etc.) there is a marked difference. Fuel ecomomy seems better too.
I am talking mainly about part-throtle response, smoothness and driveabilty. Same sensation you got by tuning an older car with an oil change, and new plugs and points.
Even if that is no indication of foot to the floor increase in actual ultimate power - it is more than enough to make me seek out good quality Diesel.
