Is Costco premium gas worth it?

Only if your car calls for it. If the owner’s manual or fuel door says premium is required, use it: low octane can cause knock that damages the engine over time. If premium is only recommended, regular is safe, with a small loss of power and economy. If the car is built for regular, premium adds nothing; AAA’s testing found no meaningful gain in power, economy or emissions.

It is not a cleaner fuel. Costco puts the same Top Tier detergent package in both grades. The only difference is octane.

What the habit costs. For a driver covering 15,000 km a year at 9 L/100 km (1,350 litres), choosing premium at today’s gaps adds:

Diesel is a separate grade sold at only a handful of Canadian gas bars; see Costco diesel prices in Canada. For every grade at one station, open it from Costco gas prices in Canada or the near-me finder.

Costco premium gas: common questions

Does Costco have premium gas in Canada?

Yes. Every Costco gas bar in Canada sells Kirkland Signature premium alongside regular. Costco Canada does not publish an octane number; drivers report 91 on the pump label, the Canadian minimum for premium.

How much is premium gas at Costco in Canada?

The average Costco premium price is 185.6¢ a litre as of the October 31, 2026 reading, a median 24.0¢ more than regular at the same gas bar. It ranges from 149.9¢ at SW Calgary to 216.9¢ at Langford.

What is the Costco regular gas price today?

The average Costco regular price in Canada is 162.7¢ a litre as of the October 31, 2026 reading. Canadian standards set regular at 87 octane minimum.

Why is the premium gap bigger in some provinces?

In Newfoundland and Labrador premium runs a median 6.0¢ over regular; in Saskatchewan it is 25.0¢. Each gas bar sets both prices against its local market, and the premium markup at nearby stations differs from province to province.

Is Costco premium gas better than regular?

Only in octane. Costco puts the same Top Tier detergent package in both grades, so premium is not a cleaner fuel. It helps only cars whose manual requires or recommends premium.

Does Costco sell mid-grade gas?

No. Costco pumps offer regular and premium only. Mixing the two in equal parts gives roughly mid-grade octane if your car needs 89.
