Top Tier gasoline has been recommended by General Motors, Toyota, Honda and BMW. But not because Top Tier might net better mileage. They recommend Top Tier because of concerns about the low levels of detergent additives in gasoline.
Over the past several years, the minimum level of detergent additive required by the EPA has declined by an estimated 50%. As a result, the ability of vehicles to maintain stringent Tier 2 emission standards have been hampered, leading to engine deposits which can have a big impact on in-use emissions and customer satisfaction.
I am one of those who believe you should shop for, and buy, the least expensive fuel you can find. Top Tier fuel can be ten to twenty cents per gallon more expensive.
There is also a problem with the idea of lots of additives: Tide with Bleach requires a larger capful to clean clothes, and gasoline with additives suffers from the same dilution problem. If I lose MPGs to a dirty engine or lose it to diluted gasoline, I still lose it.
But one should use a gasoline based on their personal values. Top Tier if you care more about the environment (and if you plan to keep your car for 5+ years). Tier 2 gas if you care more about costs of daily transportation.
We probably have an equal number of both on this site.

Down the line, none of the salemen we talked to on any of the hybrids knew much about the cars. We had to do all our own reading.

I have learned to do a lot of reading, Take multiple test drives. I have little conversation with the salesman. I always work with the Internet saleman or Fleet department. They don't know any less but at least are more prone to be quite and just answer a question they will always answer a question even thought they don't have the right answer.
I think they are so busy trying to get a sale to get the comission so they can support themselves they don't have time to read on the job and they would never think about reading at home. They don't think of their jobs as careers. Even those that have been there a long time don't do home work just gain knowledge over time. You might call ahead and ask who has been at the dealership the longes and MAYBE get someone with a bit of knowledge.
