Unleaded Petrol, Premium Unleaded Petrol & Premium Diesel (Birmingham) £1.44 at Costco

Deal Description

Costco’s Birmingham fuel station is offering unleaded petrol, premium unleaded and premium diesel to members, sitting in the same space as supermarket forecourts but typically with a more “warehouse club” approach: limited sites, high throughput, and pricing that can be competitive when you’re nearby. The key thing to note is that membership is required, so it only makes sense if you already have access (or you’re planning to use Costco regularly).

Is premium fuel worth paying extra for?

Premium unleaded and premium diesel can make sense for certain engines — for example, performance petrol cars that specify higher octane, or modern diesels where a higher-spec fuel may help keep injectors cleaner over time. For most everyday cars, standard unleaded/diesel is usually what the manufacturer expects, so the “premium” uplift isn’t automatically money well spent.

Unleaded petrol: 143.9p/l
Premium unleaded: 162.9p/l
Premium diesel: 164.9p/l

About Costco

Costco is a membership-based warehouse retailer in the UK, selling groceries, household essentials, toiletries, home and kitchen items, TVs and other electronics, computers, furniture, tyres, and seasonal products. It is known for larger pack sizes and bulk-buy options across many everyday categories. Deals often come through member-only pricing, limited-time promotions, and seasonal reductions, with savings most noticeable when buying multipacks or bigger formats. Some items are sold as special buys that change regularly, so prices and availability can vary from week to week. Costco trades online at costco.co.uk and through warehouse locations, with access tied to membership. Online ranges and pricing can differ from what you see in-warehouse, and delivery is offered on many non-food items.
