"Top-tier gas"

Dear Airheads,
I was attending a presentation for new owners by the BMW Service Manager. Before anyone asks, it does not have two wheels but four (2016 428i, rwd, with a six speed manual transmission.)
As part of a very comprehensive tech presentation the service manager spoke about "Top-tier gas". The claim is that many of the major name brand refiners have a higher amount of additives and better additives in their gas which is then referred to as Top Tier Gas. It is supposed to prevent build up of deposits on valves and a few other benefits.

The question is: Is there something to this or is it just advertising copy?

My /5 and I thank you for your comments.

I've been riding my '73 R75/5 since it came out of the crate in 1973. It wasn't designed with "top tier" gas in mind, and it doesn't seem to care as long as it gets "premium" grade fuel.

I would trust the service manager

Years ago on my R80 in which I used Chevron-Shell 87 I went from Reno to San Francisco. Because of the altitude change I would stop and get gas at a Chevron about half way and get some 92 for the lower elevation. The station I normally stop at changed to a no name station but I stopped anyway.
I filled up with 92 and took off, before I got to the on ramp I was pinging. What ever that gas was it was not 92 or 87. I slowed down and kept the RPM up for the better part of a hundred miles to use up as much gas as possible and then stopped and got some Chevron 92 and it was enough to stop the pinging.

Pinging is not our friend!! Unless you are in a submarine called the Red October!
