Premium fuel for longevity?

FUN FACT: Gasoline started out as a throw away byproduct of heating oil. (diesel)
Until the man himself (Ford) said let me see some of that stuff.

In my real world experience. I find better fuel economy running top tier fuel over top octane at a discount store. Here in Utah Maverick rules the quick stop market. In my work truck I can consistently get 2 MPG more running Chevron 85 vs Maverick 91. It’s a 6.2 gasser. I have not logged it in the Ecoboost. I just don’t put the miles on it.I just fill it with Chevron 91 most of the time.

All "Top Tier" gasolines use higher levels of detergents than what is required by state law. This will prevent fuel system fouling better than non-Top Tier fuels. These fuels come in all octane grades, not just premium. I seriously doubt if these fuels will extend the longevity of your vehicle as fuel system issues are not typically the cause for ending their useful life.

Here is where you can read about Top Tier Fuels and where you can buy them:

Our local Costco sells top tier fuel and they are always the least expensive fuel station in the area.

I just discovered how much cheaper Costco is! Never knew how bad the price gouging was in our area south of Nashville until now. Premium was $3.20 at my local Shell and at Costco $1.99! Now I can justify the occasional flooring of this 3.5 ecoboost!

I want the rated power or more, so I run 93 or better.

As far as primary source on BTU's being less on 93 vs 87 in the late 90's, I am one. I ran samples. I saw the Data. I was just student worker who was really good at using and maintaining the analytical equipment. Don't know what or who the professor was working for, but the samples were from clearly marked gas stations throughout the region.

Regardless of the past, presently there is negligible difference in BTU's across the grades, except where one grade is E0, and others are E10/E15.

Also, one could also argue, that while 93 has the same same BTU's, that because of the higher Octane, combustion can happen at greater pressure, which allows a more complete burn, which inherently makes the transfer of energy more efficient...as in per amount of fuel you are getting more of the usable energy.

As far as the OP's question...fuel is a wash. Take care of your vehicle, have maintenance done, and change the oil regularly with a quality product. After that, drive it!
