Yes, Costco gas does contain ethanol.
Most Costco locations offer a blend of gasoline that typically includes up to 10% ethanol, which is common for many gas stations across the United States.
Ethanol is often used as an additive to reduce emissions and improve octane levels. This means that if you fill up at Costco, you’re likely using a fuel that contains this renewable resource.
Ethanol is derived from corn and other plant materials, making it a more sustainable option compared to pure gasoline.
For those concerned about the impact of ethanol on their vehicles, it’s worth noting that most modern cars are designed to handle this blend without issue.
However, older vehicles or certain small engines may not perform as well with higher ethanol content.
If you’re uncertain, it’s always good to check your owner’s manual or consult with a mechanic.
