To steer clear of peak crowds, plan your fueling outside weekday mornings from 7-9 AM and afternoons between 4-6 PM. Midday and late evenings tend to be less busy, making your stop quicker and more efficient.
Do I need a Costco membership and specific payment methods to buy gas in Merrillville?

What should road-trippers passing through Merrillville check before entering Costco gas?
Before stopping, verify your fuel gauge and estimate how much gas you need to avoid unnecessary wait times. Also, consider nearby highway traffic conditions, so you can decide if a quick stop at Costco is worth the detour.
How should I handle longer-than-expected lines at the Merrillville Costco gas station?
If the line looks long, assess your fuel urgency. If you have enough fuel to delay, try returning during off-peak hours or check nearby gas stations. Patience during busier times can save you stress and time.
Does weekend timing affect fueling at Merrillville Costco gas, and how?
