What Ron Fuel do you use?

If it is placebo, why does my R state it as the required fuel (as did my high-compression twin charged Mk5 GT Sport)?

I think he's saying running higher Octane than the car requires isn't worthwhile and any improvement is placebo. Not that there isn't a difference between low and high Octane fuels.

At the moment, 98RON + 25% E85 (107RON).

98 in my Jetta as required. 98 in our Fabia just because the price difference is minimal and it gets marginally better consumption figures.

Interesting seeing the responses. I always stick to 98. I get better consumption when compared to 95. Also the fuel cap says recommend to use above 95. So 95 being minimum I choose to go higher beside my consumption point. I would like to know if the higher Ron Fuel maybe effect it in a negative way? Also... Are the fuel really what they state they are? Is 95 really 95 out of the nozzle? I read some stuff online about how the Ron is pretty much a guide. Unless someone has a lab an can test it then the myth can be busted... Keen to know your thoughts on these points.

I've only used 98 (mostly from 7-11, Caltex and BP) (Mk7 92TSI), and according to the computer, I'm getting 4.9l/100km (which matches my rough calcs)

I walked past someone the other night filling their Golf at the local Enhance - they have 98E10 (I'm assuming they were putting the 98 in not the 94E10). Kicking myself for not stopping to ask them how they found it.

Would the E10 bit possibly harm the engine (or make it not run so well)? Or does the 98 bit compensate?

Edit: and I calculated that I've saved $2000 or so in fuel compared to my old Territory!
