What happens when premium gas is put in a regular gas car, Ford Escort?
Nothing special, you’re just wasting money on the petrol. It should get your car some boost and quality, but unfortunately you’ll not see any difference. I would recommend to buy eco cars, where you have a possibility to combine electric and gas engine. As an example of Ford car you mentioned before, it might be a new 2019 Ford Eco https://coolcarsforever.com/ford-ecosport-2019/
Without my glasses on, I put premium unleaded in my Ford escort. It only takes regular. What could happen and what should I do? Money will disappear from your wallet. Premium gas has higher octane levels. Octane is basically a “power” level, but more is not necessarily better. Too low octane, and your engine might “knock” (kind of a shudder”). Most run just fine on regular. If an engine requires a higher octane, you use the higher fuel. But if it doesn’t require it, it’s sort of a waste, because your engine can’t take advantage of it. I have one vehicle that has a custom engine and requires super premium (which I give it). The rest just require regular fuel, and to put in super would just be a waste of money, because it wouldn’t make them drive or perform any better. You didn’t hurt anything, you just paid for a gas quality you didn’t need.
