General opinion is they dont make much difference and the oil has been suspected to damage MAF sensors, Ive not fitted one for these reasons
A clean out and Bypass of EGR and a Rover ron seems to be the best value for money

And don't forget to change the 'Depression Limiting Valve Filter' . A new filter allows the beast to breathe properly and produces a noticeable improvement in overall performance. More importantly a blocked filter if ignored will eventually lead to Turbo problems and possible catastrophic engine failure.
