Current Roseville station prices

The latest Costco Gas Price Now listing for the Costco at 6750 Stanford Ranch Road showed $5.259 for regular gasoline and $6.299 for diesel on July 30. The independent tracker says its prices are refreshed daily and can change at the pump during the day.

At Five Star Roseville, 808 Sunrise Avenue, the station’s page displayed $5.199 for unleaded 87 and $6.099 for diesel. The page labels those figures as current prices but does not show a visible timestamp.

That creates a station-level difference of about 6 cents per gallon for regular gas and 20 cents for diesel between the two listed locations. These figures are station listings, not citywide averages, and other Roseville stations may be higher or lower.
