Ah, the vintage enthusiasts. If you drive a classic from the 80s or earlier, mixing can be risky. Ethanol eats rubber seals and plastic bits that weren’t designed for it. So for your beloved old-timer, stick to 91—or better yet, find ethanol-free fuel.
For everyone else—the daily commuters, the road-trippers, the “I-just-want-to-get-home” crowd—mixing is perfectly safe. Your fuel system is already tweaked to handle ethanol. It’s not a chemistry experiment; it’s a convenience.
