Gas prices have been the lowest they have been in awhile.

As of Tuesday, September 13th, pumps in Airdrie were sitting around 86.9 cents per litre.

Analysts are attributing the low cost of fuel to large inventories, and the fact that suppliers are switching to winter grade fuel that is cheaper to refine.

Gas prices are currently 12 cents per liter cheaper then they were at the same time last year.
