Ford Lawnmowers Mtd Or Ayp Someone Told Me: DON'T Use 87 Octane Except For Lawnmowers And Hyundai Excels. I Have A Truck. Is This True?

Someone told me: DON'T use 87 octane except for lawnmowers and Hyundai Excels. I have a truck. Is this true? - ford lawnmowers mtd or ayp

I have a '95 Ford Ranger. I wondered why the best gas stations, and this person said of 87-octane fuel used on lawn mowers, and I do not even know what a Hyundai Excel. I know Hyundai builds cars and step-rockets, and various other things with motors in them, but I do not know what it is like a complement to Excel and I do not. I just want to know whether this statement has some vailidity or if it is pure BS
