What are owners running their 328i s on?

The brochure says 95 is okay, but the dealer said 98.

As per the E90, the F30 can run on 91RON, 95RON and 98RON and even (min 91RON) fuel that contains up to 10% ethanol. Please note that all fuel consumption and performance figures quoted by BMW Australia for the F30 are based on 98RON.

I have been running my E90 on 98RON and will run my F30 on 98RON.

98 every day of the week.

I plan on doing a performance comparison for both consumption and power in the first 2 tank fulls before settling on either.

I know you've got the best of intentions in doing this, but here's my 2c on the idea (best intentions also)

*flamesuit on*

so here's the thing, I reckon this is going to be pretty pointless as you're not going to have controlled conditions for your experiment.

Power difference, given you're not going to be racing, will be negligible. 98 should give a slightly better throttle response, all other things being equal.

If you were keeping your car long-term, I'd suggest the 98 for a number of reasons, however if you're just worried about the pennies and not your engine, go 95.

/end my 2c worth

I remember reading that a minimum of RON95

I wouldn't recommend you use anything less than 98RON, even on the e90, though it says you could use other lower spec fuel, there is a noticeable difference in the way the car picks up when on 98 fuel. Plus, I have been told by a BMW mechanic that regular use of low grade fuel can ruin your engine, so stick to 98RON.
