Winter Warmth, Year-round Service

Linn Cooperative offers a full range of services and payment programs for our residential, commercial and agricultural propane customers.

Initiating Service

With four propane routes and five bulk plants, we are responsive and efficient when serving customer needs for propane. All our delivery drivers are certified, and we employ two service technicians as well.

There are a few simple steps to follow to start your propane service:

  • Fill out a credit application.
  • Once credit is approved, we’ll need to know if your tank is owned or leased. For new service, we may need to arrange to get a tank set. Linn Co-op does sell and lease tanks.
  • If your tank is owned, we do a leak check before the first fill as a safety procedure.

Delivery Options

Once your service is ready to go, we’ll work with you to determine how you’d like to handle future deliveries. 

Schedule fill. If you opt for this program, our drivers will fill your tank as needed as part of their regular route. 

Will-call fill. In this option, it is up to the tank owner to watch the tank and call in when it needs to be filled. Please allow five business days for delivery. Try to call when your tank is at least 20% full; otherwise, additional charges may apply. If the tank goes empty a leak test will need to be conducted before it can be refilled. There also may be rush charges if a fill needs to happen in less than five days.


We have payment contracts available to fit your budget. For residential and commercial customers, our two most popular options are prepay or budget billing. We also offer contracts for grain dryer and livestock customers. 

Contract details are typically available in May or June, and contracts most often run from September-March.

Please select LP Prepay Contract Printable to contract gallons. Then print, and mail to the Marion office with check for full prepaid total amount. Contracts received without a check will not be processed. Call for current LP contract price if after July 15th 2023.

Please select LP No Contract Fillable if you are NOT contracting gallons. Once form is filled out and signed a copy gets emailed to Linn Coop and you. No need to print and mail. 

Please inquire at main office for any questions. 

Budget contracts are no longer available. 


24/7 Emergency Line



Safety is our number one priority. If you smell propane, then there are certain steps that need to be taken.

  • First, leave the house.
  • Call for service from an outside line.
  • Don’t touch switches or anything electrical that could create a spark in the house.
  • Shut gas off at LP tank if you are comfortable doing so.
  • Call Linn Cooperative and someone will be sent out immediately. We offer a 24/7 emergency line.

Only the Best for Farm and Fleets

We serve our farmers, businesses, schools and other organizations with superior-quality Cenex-brand fuels. We utilize five delivery routes from five bulk plants. Our drivers get to know your needs and keep your tanks full, whether you need diesel or gasoline.

Premium Diesel Fuel

Get the most out of your equipment by using our premium diesel fuels: Ruby Fieldmaster, which is dyed for off road use, and Roadmaster for highway use. 

These premium products have been shown to restore power by 4.5%, restore fuel economy by 5%, and clean injectors and boost lubricity to reduce costly downtime.


We’re proud to offer Cenex TOP TIER™ Detergent Gasoline for bulk delivery. We carry 87 octane, E10, and unleaded with no ethanol added. Retail customers can visit our Car Care Center in Marion, IA, for additional choices. 

With 2.5 times more detergent than regular fuel, TOP TIER maximizes performance and efficiency for a cleaner engine and fewer trips to the mechanic, all from simply fueling up your tank.

Fuel Contracts

Ask about our spring and fall contract for diesel on the farm. We also offer all-year contracts for commercial accounts.

Cenex Total Protection Plan

Warranty your new or used equipment for up to 10 years or 10,000 hours when you exclusively use Ruby Fieldmaster diesel and Cenex lubricants. You get unsurpassed coverage, while helping to ensure that only high-quality energy products go into your equipment.

Maximum Protection for the Toughest Jobs

Whether you have a high-horsepower tractor, semi-truck or a personal vehicle, Linn Cooperative carries a full-line of Cenex-brand lubricants and hydraulic and transmission fluids to meet the challenging demands and tough environments of east-central Iowa. 

Cenex Lubricants have more than 75 years of proven performance, guaranteed protection and dedication to serving the needs of construction, transportation and agricultural communities. 

We can deliver in bulk for some products (be sure to ask!). We also have package sizes available from 1 quart to 55-gallon drums.


With Tier 4 engine systems in full swing, Linn Co-op offers DEF to its customers. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water. We carry DEF in multiple sizes, including drums, totes and bulk.
