Optimax in an '02 CTR ?
Discussion
Hi Folks,
Apologies for bringing up the subject of Optimax again. I know it's been covered a lot in other forums and threads but...
I have been doing some research trying to work out if I should consider using Shell Optimax in a CTR. There is a lot of chat about it other forums, and the general concession seems to be that it is a better petrol and it helps keep the engine clean. However, it was also suggested that you only get a real benefit if the ECU in your car can adjust to the higher RON grade of Optimax.
I know the CTR is set to use 95 RON petrol by default. The only threads I have been able to find about ECU changes have been in the TVR ones, so I thought I'd try and find out specifically what other CTR users are doing regards using Optimax.
I also read on one thread that using the wrong grade fuel can damage the cat of your car. This is not something I have found stated anywhere else (quite the reverse), and indeed Shell’s own web site suggests any unleaded or super unleaded car can benefit from Optimax. However, I’m naturally nervous about doing anything that could break the CTR so again would appreciate the views of any other CTR users out there.
