My stuff says 89 is recommended so that is what it gets. Echo, Stihl, Shindaiwa, Tanaka all recommend 89 at the minimum for their equipment.

I had a volvo that required 89 octane. Well, as I remember, it required 90 octane but I figured 89 was closer to 90 than 93 was so I went with that. LOL

Ethanol-free gas bro. Ethanol causes major problems in engines like mowers.
Putting higher grade gas in your truck is literally throwing away money. Go with whatever grade the car requires. There have been multiple studies showing that higher grade than what your vehicle requires gives no benefit.

The only other reason to go up in octane, when it comes to name-brand fuels at least, is to take advantage of increased detergent additives in the fuel. I fill up on a tank of 89 or 93 Shell (with a good helping of Seafoam or Techron) every few months with my beater Ranger. Seems to clear up a gummy injector that sometimes causes the truck to have a sluggish start when it sits for more than an hour.
Costco uses the same premium detergents in all of their grades. My membership literally pays for itself with the gas savings alone. I work a few blocks away so 90% of my gas comes from there.

What does higher octane do for the car?

My truck can take 87 but recommends 89, so I always put 89.
Probably beating a dead horse here, but you shouldn't put 91/93 in just for the sake of it. Read your owners manual and put what the factory recommends.
Higher octane is for higher compression motors. If you put high octane in a motor programmed/built to run 87 it'll knock.
