I previously started a thread on Optimax but at the time there was no real knowledge. I have a 2000 R34 from Middlehurst. It went into Middlehurst for an oil change service. There are 37700 on the clock and only 1700 since the last service. The car has been running rough for the last 6 months at least and I asked the garage to investigate. They replaced the oxygen sensors and the engine runs sweet as a nut. Paul at Middlehurst suspects the Optimax which is the only fuel I use and I suspect he has now seen the same problem arising recently. However, the bill was £800+. The sensors have gone away to Nissan but I dont hold my breath. I am near to Marinello so intend talking to them to see if they are experiencing anything like this with Ferrari engines. I havent any issue with Middlehurst but maybe with Shell.
Any one got any ideas? In the meantime I intend to steer clear of Optimax and would advise any one else to do likewise
