I’m not sure how the fuel is in other countries so this might only apply to the Australians here.
I just use normal unleaded in my car at the moment, and have never tried the higher octane such as octimax of vortex, because the car uses enough petrol as it is I didn’t want be spending more on it.
But does it make a noticeable difference in rotaries? All my friends use it in their piston cars and thing it makes a huge difference.
Is it worth me using it??

Thanks Michael

 

I remember reading a big write up about it, it said that NA's will produce hardly any significant noticeable differnece by running premium grade fuels, no with Turbos its a must...

 

Stick to the unleaded dj. n/a rotaries work best with low octane fuel.

 

Yea, regular is just fine.

 

Yelp, turbo run the best you can find reasonably, I ran premo in my 88 vert and I noticed ZERO difference
