added the same dosage ...
and my ride feels dumbed downed.
Too much ZDDP ?
When you say ride, do you mean motorcycle or car?
You first say it made your engine quieter, than the second time you used it you say it was dumbed down. Do you mean you got less performance, or the noise came back? I highly doubt the ZDDP alone caused a decrease in performance. You are in the UK, so I am not sure if you have a change in gas formulation at different times of the year which would dumb down your ride. You might have bumped a wire loose while changing the oil. Depending on where your oil filter is located, you could have damaged the O2 sensor. On 4 cylinder cars, the oil filter is in front next to the exhaust and O2 sensor. You could have also knocked a vacuum line loose or damaged a brittle spark plug wire. I don't know. I am just throwing out guesses. If all else fails, you could change the oil without adding ZDDP.
