When my wife daily drove an E46 330i, we would fill the tank with Top Tier regular. On trips where I wanted the extra performance, I would fill with a higher grade, as it would deliver a couple more HP.

In your case the additive package in the fuel is an important of a decision as the RON rating, as you'll want to keep the intake valves & combustion chamber clean. You'll need to do some research as to what fuels are in your area and offer the best cleaning.

Now she drives a F10 535 with a N55 engine. LSPI is of great concern with turbo motors. Now we use premium and top tier to help negate any LSPI (not a concern for M54 or the like engines) along with engine oils that help combat LSPI.
Ok thanks. The only ones that i know of with additive premium gasoline is Shell V-Power 98 and Total Excellium 98. I should one of those two 98 ones?
