For various reasons, hi-test fuel burns longer than regular fuel, and so may make the engine run hotter by heat-soaking.

What happens if you put 87 octane in a regular car?

In the old days, running 87 octane in a car that required premium fuel would cause the engine to start knocking before the car even left the gas station, but things are different today. If you mistakenly fill up with regular fuel, your car’s ECU will adjust engine timing and performance to work with the lower-octane fuel.
