Premium from Costco ( costs as much as regular at Shell, Exxon, BP, RaceTrack, Buc-ees, etc.. )

I believe the gx460 likes premium fuel, 91 octane, but I’m wondering if it is ok to run 87. I know some manufacturers say premium fuel to optimize hp and performance, but a number of them that recommend premium, are ok with the 87. Not sure about the gx but with today’s fuel prices I figure I’d ask.

im kinda trolling in the GX forums haha but also keep in mind you'll get more mpg out of premium than regular... reason being regular contains ethanol to reduce emissions. Ethanol doesnt burn as efficiently as gas, so it burns more going 1mile than it would burn gasoline. Premium fuels dont have ethanol. Well at least this is how it is in canada, not sure if the premiums have ethanol down in the states or not.

Always a controversial topic.... but interesting read from someone on IH8Mud who claims they "work specifically on steady state operations within engine calibration at an OEM"

I bought a gallon of gas and mixed in a small bottle of 40:1 oil to put in my chain saw. Long story short, chain saw went south but I hate to waste almost a gallon of gas and wondered if I put in my 2022 GX would it hurt anything?

With all due respect, your GX is worth way more than your chainsaw. I'd save it for a bonfire instead.

Not recommended. Hell no. If you do at least make a YouTube video of it 😆 it could go either way.

Well looks like the jury vote is in. Not worth taking a chance to mess something up. Will just keep the gas to give to a neighbor. As a side note I ended up renting a electric chainsaw from Home DePot. Had a huge limb fall on my driveway. Luckily no cars were parked or dogs hit.😄
