Oil Additives

[cjcposh]

I presently own a 9-5 aero 2002 with 246000 miles on the clock and would be interested to hear from anyone that has used oil additives with this engine.Ive looked at Wynns Charge and STP oil treatment which appear to be a proposition.I remember using these on my old Mk1 Cortina back in the 60s and would think technology will have improved them.Love to hear opinions,case studies and experiences as i would like to reach 250000 in the car.

Don't bother......just keep using fully synthetic oil and change it (plus the filter) regularly.
