New Optimax Extreme and which fuel best for Jazz

[fundies]

My Jazz is slow, no matter what kind of fuel goes in. So I stick to the cheapest with a little injector cleaner every now and then.

No matter how quick or slow your car is your garenteed to get extra kms out of using 98+ ron. Question is is the extra few cents/litre worth the extra few kms/cleaness of the engine. I personally think it is.

I personally disagree with this. Forgetting the no. of km's vs cost, from everything that I have read on the topic, the relatively small gain that you see in cleanliness vs cost is not worth it.

I use Caltex Vortex 95 octane (as I lease my car and can't take it to any other fuel suppliers). Between the 95 and 98 Octane on Vortex I noticed no difference in performance the fuel economy was no better. So I have stuck to the 95 octane fuel. The 91 octane makes my engine more noisey. I get on average 500++ KM with city driving with the 95 octane. I own a VTI-S CVT as my daily driver.
