Costco gas is generally considered good for Audi and other vehicles. According to various online discussions and forums, many Audi owners have shared positive experiences with Costco gas. Some users have mentioned that Costco gas is of good quality and comparable to well-known brands like Shell in terms of octane levels, and they have had no issues using it in their Audis [1] [2].
Additionally, it’s mentioned that Costco’s gas quality meets high purity standards and exceeds Top Tier requirements, which are important factors for vehicle performance and maintenance [6].
It’s worth noting that in many regions, the gasoline sold at different gas stations comes from the same terminal, so the differences in quality are often minimal. Therefore, you can confidently use Costco gas for your Audi without significant concerns about its quality [3]. However, always follow your vehicle’s manufacturer recommendations for fuel octane and any specific requirements.
