Built around petroleum and distillate sales and delivery, National Oil's main areas of operations are both consumer and wholesale driven.  Whether filling a home heating oil tank, or a semi-load of fuel delivered to underground storage, National Oil keeps America fueled and operating smoothly.

Consignment Billing

Fuel deliveries don't have to put a drain on your bank account.  With our consignment billing, keep your cash flow flowing steadily and only pay for what you pump.  Simply use our WINACH program to report your sales and we'll take care of the rest with automatic drafts to/from your account, tax accounting, and credit card inclusion.

Invoice Billing

Want the best fuels at the lowest cost?  Use our simple invoice billing option and we'll deliver the fuel and take care of other incidentals like taxes and credit card credits.  Flexible terms available.

Station Leasing

You have the business model in place, all you need is the infrastructure.  National Oil leases sites that include the building, tanks, canopy, and pumps, leaving you to concentrate on your business.  Talk to us about our existing locations for lease and those coming up in the future.

Site Development

National Oil partners with specialized builders of our convenience stores to provide an efficient, usable traffic flow pattern for customers to maximize your sales.  Whether raze, rebuild, or remodel, we can get the job done.

Farm and Home Delivery

Farm fuel and home heating oil delivery are just a phone call away.  Our retail delivery drivers are based out of Bluffton, Decatur, Berne, Huntington, Warsaw, Monroeville, and Montpelier, Indiana.
