How Do You Rate Optimax Extreme?

[Kennedy]

After a month (~2,000k's) of running exclusively on Extreme in the R33GTST, I did a fuel filter change on the weekend. Cut it open and no sign of any foreign material, deteriorated fuel hose etc. That means zero effect from the 5% ethanol, as expected. So we will continue to use it.

WooHoo!!!! Been waiting on your diangnoses SK. You have confirmed what I thought. I did crack open my fuel filter and hoses last month after 20 tanks but wasn't sure what I was looking for.

Extreme kicks asse!!

Current status, after 8 months of running exclusively Shell Optimax Extreme 100 ron.

After 3 fuel filter changes I still haven’t found one sign of fuel system rubber or metal deterioration.

I cleaned the injectors last week and there is not one sign of any effect on them either. I also flow tested them and they performed exactly as they did last time I flow tested them.

Based on the results with the R33GTST, I have now started to use it in the Stagea, which I will be tuning again very shortly to take advantage of the extra performance on offer.
