Holiday is inviting the community to celebrate its 60th anniversary with a free-to-attend “birthday party" and grand opening event at its newest location in Bluffdale. During the summer, Tuesdays, better known as Tank Up Tuesdays, will be Holiday’s marquee anniversary celebration with fuel 20 cents off all day and 60 cents off from noon to 4 p.m. for Holiday loyalty card members.  Tank Up Tuesdays will be held at a select group of locations each week, which customers can find online or on the Holiday Oil app.
