Reduced performance might be the only issue but why buy a 500+ hp car to use fuel for a civic that'll reduce performance?!? If you can justify using proper fuel, go buy a 528 or something else that doesn't require higher octane.

You are implying that lower octane will "detroy" an engine but then you say it will just reduce performance. Do you know what octane is? It has NOTHING to do with the quality of the fuel. So you can agree or not, I don't care, but know the difference between gas quality and octane. It is basic science.
In reference to why someone would use 87 octane vs 93 octane, it is because they don't need 575 hp on tap for a daily driver. So they would rather save $500/year instead of literally burning it up for no reason.
BTW, your base model 5 series example also has turbochargers but you recommend 87 octane for that car. This further makes your post even more confusing. |
If you could read, I said at the minimum, would reduce power. And if you don't NEED 575hp, why buy it to begin with?! It's ludicrous.
Also, again if you read, I said high horsepower turbo engines. A 240hp four cylinder isn't high horsepower.
While octane doesn't dictate quality of gas, point is the engine isn't designed to run on 87. If you want to run 87 to save a measly $500/year, save THOUSANDS and buy something less prestigious, less flamboyant, less maintenance, less everything. Your logic is terrible.
