Gas Saving Tips for Salt Lake City Drivers

Fill up before holiday weekends. Memorial Day, Fourth of July, and Labor Day consistently see 10-25 cent price spikes as demand surges. Topping off Thursday before a holiday weekend beats the rush.
Download the Upside app for cashback on gas purchases — users report average savings of 20-30 cents per gallon on qualifying transactions.
Check if your grocery store offers fuel rewards. Kroger, Safeway, Giant, and many regional chains discount gas by 10-50 cents per gallon tied to grocery spending thresholds.
Use regular unleaded unless your owner's manual specifically requires premium. For the majority of vehicles, there is zero performance benefit from a higher grade.
Plan fill-ups along your existing commute route rather than making special trips. A station you pass daily that is 10 cents cheaper beats a special detour to a slightly better price.
