It may seem like buying higher octane “premium” gas is like giving your car a treat, or boosting its performance. But take note: the recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage, or run cleaner. Your best bet: listen to your owner's manual.
The only time you might need to switch to a higher octane level is if your car engine knocks when you use the recommended fuel. This happens to a small percentage of cars.

I think the highest mpg I got out of my Coyote is around 23-24. I think I got about 25-26 at best with my LS8, but that was with cylinder deactivation, exhaust, and the flat cool roads of southern New Mexico.

I hope you're trolling.
Unless your engine has a higher compression ratio and advanced timing (basically all of which require a higher octane rating) then putting premium in is a complete waste.
In fact, it leads to excess carbon buildup which can damage an engine over time.

I do. I put premium in it all the time because thats what manual says
Putting premium in a car that doesnt need it just because it is cheap is dumb

I'm hoarding barrels of premium in my garage. I already have 3 barrels.
When the price of premium goes up to 3 bucks I'm going to sell for 2.50 and make bank.

Do people actually not use premium? Figures that poors wouldn’t care about taking care of their engine
A good troll would have stated that you only use 98 RON.

My SVT Lightning specifies premium gas, so I buy it regardless. I think you get better gas mileage with it.

Not needed unless manufacturer specifies.

I have an Ecoboost which supposedly gets a little bit of extra Hp.

I was just making sure you weren't starving a poor S63, they will retard timing and run OK for a tank but will throw a CEL and maybe even go into limp home if continually fed 86/87 octane. The hot-vee layout doesn't like higher than normal EGTs.
My wife has the same engine in her M5 Comp, great engine just hoping they have all the issues with the N63 sorted in the S63.

You don't just put any old gas in a sexy little whip like mine... premium from Shell, Chevron, or QT only.

Not premium, but I buy no ethanol added gas.
