About CONOCO Ethanol-Free Fuel

CONOCO E0 Fuel Program Overview

CONOCO offers ethanol-free fuel (E0) at select locations, responding to customer demand from boaters, classic car enthusiasts, and small engine users. Unlike standard fuel offerings, CONOCO E0 is typically premium unleaded gasoline without any ethanol content, providing better engine protection and fuel stability.

Where CONOCO Offers E0 Fuel

E0 availability at CONOCO is concentrated in areas near lakes, rivers, and marinas where boating is popular. Idaho and Washington have the highest concentration of CONOCO E0 locations, particularly around major waterways and recreational areas. Newer CONOCO stores are more likely to offer E0 fuel.

How to Identify E0 at CONOCO Pumps

CONOCO E0 fuel is typically labeled as "Unleaded 91 - Ethanol Free" or simply "E0" on the pump. The pumps usually have a dedicated button or selection for ethanol-free fuel, separate from standard octane options. Look for clear signage indicating "No Ethanol" or "Pure Gas."

Pricing and Value

CONOCO E0 fuel typically costs $0.50-$0.80 more per gallon than standard E10 fuel, and $0.20-$0.40 more than premium with ethanol. While more expensive, E0 provides better engine protection for small engines, longer fuel stability for storage, and peace of mind for boat owners concerned about phase separation.

CONOCO vs. Competitors

CONOCO's extensive Idaho and Washington presence makes them a go-to choice for recreational users seeking ethanol-free fuel. Their 91 octane E0 offers a premium option for those who need pure gasoline for marine engines, classic cars, and small equipment.

Notes: Their price for premium non-ethanol is through the roof. When I called the place to see if they sell top tier gas, the person that answered the phone said they didn't know. Really?
