If your car runs well, stick with a good fuel brand and skip lower quality ones like DaliOil. If your car feels shaky and lacks power, try higher octane. But using 100 octane instead of 95 for regular driving isn’t necessary.

It’s just a placebo and doesn’t do anything.
No, and using too much higher octane can cause problems, as fuels with higher octane than what your car requires might not ignite well. Mid-grade should be fine, but using premium in a regular car can stress the engine.
I haven’t done a mileage test, but I feel there’s a noticeable difference in performance with higher octane. I have a 2021 Elantra N Line and it has a 1.6 turbo engine. The ECU adjusts based on knock readings. Is the slight performance gain worth the cost? That’s up for debate, but it is for me. Some might argue that it could actually harm the engine since it’s not what Hyundai recommends.

Older turbo cars should use higher octane, but nowadays, 87 octane usually works well.
I’ve noticed better gas mileage with higher octane. About 15 to 20 miles more per tank with Top Tier gasoline like Chevron. The cheapest fuel gave me the worst mileage. I haven’t tallied up the cost per mile yet to see if it’s worth it. I drive a 2013 Hyundai Accent 1.6L.
I only use the highest octane for long drives since it gives me an extra 20 to 30 kilometers per tank. For stop-and-go traffic, I stick to the regular grade.

Premium is about 20% more than regular from what I’ve seen. Unless you have a small tank or all grades cost the same, you’re just wasting money.

And I see no reason to stop my approach.
