Costco’s premium gas is 91 octane.
Costco does not offer 93 octane gasoline. Their premium fuel, which is often referred to as “Top Tier” gasoline, is 91 octane. This is suitable for many vehicles that require higher octane levels for optimal performance.
The reason Costco sticks to 91 octane is to meet the needs of most consumers while keeping prices competitive. Many drivers find that using 91 octane helps improve fuel efficiency and engine performance, especially in vehicles designed for it.
If you’re unsure about what fuel to use, always check your vehicle’s owner manual. It typically provides the recommended octane rating for your specific model.
Using lower than recommended octane can lead to engine knocking, which can cause long-term damage. So, it’s best to stick with what your car needs.
Costco’s fuel prices are generally lower than many competitors, making it a popular choice for drivers looking to save on gas. Their premium gas is often praised for its quality, as it meets higher standards than typical fuels.
Many Costco locations have busy gas stations, so be prepared for potential wait times. However, the savings can be worth it, especially if you fill up regularly.
What is the difference between 91 and 93 octane gas?
The primary difference is the octane rating, which indicates the fuel’s ability to resist knocking. 93 octane is designed for high-performance engines that require more resistance to pre-ignition.
Is Costco gas good quality?
Yes, Costco gas is considered high quality. It meets the Top Tier standards, which means it has added detergents to keep your engine clean.
Can I use 91 octane in a car that requires 93?
It’s not recommended. Using a lower octane fuel than what your car requires can lead to engine knocking and potential damage over time.
Do all Costco locations sell premium gas?
Not all Costco locations sell premium gas, but most larger stores do. It’s best to check with your local Costco for availability.
Is Costco gas cheaper than other gas stations?
Typically, yes. Costco gas prices are often lower than those at other gas stations, making it a popular choice for budget-conscious drivers.
