Pro Tips for MIDDLETON Costco Gas
- 1
Diesel pump location: At most Costco locations, diesel pumps are on a separate island — often at the end of the fueling canopy or in a dedicated commercial lane. Look for the yellow or black diesel nozzle handle.
- 2
Best time for diesel: Weekday mornings (Tuesday–Thursday, 7–9 AM) have the shortest wait times at this MIDDLETON location. Diesel lanes generally move faster than gasoline lanes because fewer vehicles use them.
- 3
Track prices before your route: Costco updates diesel prices daily based on wholesale distillate costs. If you're planning a long haul through MIDDLETON, bookmark this page and check the price the morning of your trip.
- 4
Maximize fleet savings: Stack your Costco membership discount with a commercial fleet card or cash-back credit card. The Costco Anywhere Visa gives 4% back on fuel purchases (up to $7,000/year). Sam's Club Mastercard returns 5% on fuel. On high-volume diesel fills, those percentages add up quickly.
