Let’s be honest: "E5" sounded like a robot from a low-budget sci-fi film. The new naming system is a cultural win for anyone who doesn’t have a chemistry degree at the petrol station. It’s part of a broader trend toward consumer-friendly transparency—like how "high-fructose corn syrup" got renamed to "corn sugar" (and then we all got suspicious anyway). The difference here is that Super Unleaded actually means something: higher octane, less ethanol, more grunt for your engine.
Funnily enough, in the US, they’ve been calling it "Premium" for decades, while the UK clung to the "Super" label like a sentimental parent. Now we’re all in sync. So next time you’re at the pump, you can confidently say, "Fill it with the good stuff," and the attendant won’t look at you like you’re speaking ancient Greek. It’s a small victory for clear communication in a world of abbreviations.
Practical Tips for the Pump Pilgrim
Tip one: Check your car’s fuel flap or owner’s manual. If it says "E5" or "unleaded 98 RON," you’re hunting for the green-handled pump—that’s often the Super Unleaded nozzle in many chains. Don’t rely on memory; I once absentmindedly put E10 into a 2008 hatchback and spent a week imagining engine knock that was probably just my conscience.

Tip two: Super Unleaded isn’t just for old cars. If you drive a performance model—say, a hot hatch or a turbocharged saloon—the higher octane (typically 97 or 98 RON) can improve engine efficiency and throttle response. It’s like swapping your morning filter coffee for a double espresso: more zip, fewer jitters (well, fewer engine pings).
Tip three: Don’t be fooled by "Premium Diesel" signs. Your petrol car still wants the Super Unleaded nozzle, which is usually labelled in bold letters. If you’re unsure, ask the cashier—they’ve seen every combo of confusion, from people trying to put AdBlue into the tank to someone using a diesel nozzle on a motorbike. You’ll just be a mild case.
