Gasoline Quality: Retailer Risk Assessment Information
Michigan Department of Agriculture & Rural Development
Motor Fuels Quality Program
The Michigan Department of Agriculture & Rural Development receives over 1,000 complaints against retail motor fuel stations every year. Poor quality motor fuel is one of the significant causes for consumer complaints. Selling substandard motor fuel will make your station liable for substantial fines and/or prosecution under Michigan law.
Investigations have shown that several factors that contribute to poor quality motor fuel were within the control of the station operator had they known what to look for. The Department has compiled this list of the more common factors to assist station owners in achieving and maintaining compliance with the Motor Fuels Quality standards.
- All fuel storage tank fills must be clearly labeled with a tag or collar to identify the contents or color-coded. If you use a color-coding system, the color-code key must be posted in a conspicuous place so it is visible to the transport driver. When utilizing a color code system; the gasoline storage tank with the lowest octane product shall be white, the gasoline storage tank with the highest octane product shall be red, and the gasoline storage tank with octane between the highest and the lowest shall be blue. All other storage tank colors must be identified on the key. The color should extend beyond the lid itself to prevent switched lids. Make sure the lighting is acceptable for night deliveries. New or replacement transport drivers unfamiliar with your station could drop the wrong product into a tank. Even a small amount of mis-delivered product can result in a violation.
- Keep the storage tank fill caps, vapor return lines, and gaskets in good repair to prevent water entry. Check for rust or breakage on the vapor return poppetted dry breaks. Keep the overfill sump areas dry.
- If you have an electronic monitor for water, periodically stick your tanks with water indicating paste to check the water levels to make sure the electronic monitor is working correctly.
- Reminder: It is against the law to sell motor fuel from storage tanks with water levels in excess of 2 inches. It is required that you have testing equipment available to determine the water /alcohol level in the storage tank, and that you periodically test your tanks for water level.
- Reminder: Ethanol blends can react to even small amounts of water in the storage tanks and cause fuel quality problems. You should remove all water bottoms in storage tanks containing ethanol blends.
- Make sure your supplier knows the motor fuel products you are ordering and know what you are getting especially gasoline octane values. Premium comes in many octane levels.
- Keep and review detailed delivery documentation from your supplier. Bills of lading, delivery or drop tickets, tank monitor printouts, invoices, and any other documents pertaining to gasoline delivery to your station may be your best defense if a violation occurs. Drivers should be signing and fully completing the delivery tickets, including before and after stick readings.
- Review the tank monitor drop report printouts after a delivery. If you see a significantly larger or smaller delivery on the monitor printout than what the driver recorded, check further. Cross contamination of different grades of gasoline or diesel fuel with gasoline is a common violation.
- Review the certification of octane from your supplier. Make sure your pumps are labeled with the correct grade name for the octane you are receiving.
- Reminder: Delivery documents must be available for the department's review at the station for 30 days. Employees should know where they are kept.
Gasoline Quality Problems:
- If you receive a consumer complaint, observe the clarity and purity of the gasoline visually by placing it in a clean, clear jar designated just for this purpose. The gasoline must be clear and bright at 70°F and free of visible sediment. If you notice water (even a few drops), sediment, or cloudiness, take steps to correct the situation.
- If you notice or suspect that something is wrong with the product you are offering for sale, stop sale immediately until corrective action can be completed.
- If you determine that the octane is below what is posted, lowering the price is not proper corrective action. Consumers purchase octane based upon their vehicle needs. The correct grade name must be posted.
- If you need assistance to correct a problem contact your supplier, or brand parent company for assistance. You can also contact the Motor Fuels Quality program at 517-655-8202. The department will not tell you what to do to correct a problem because this is ultimately your responsibility, but we can offer some advice or guidance recommendations to assist you in making the best decision for your business situation.
- Consider instituting your own quality assurance program and having your product tested periodically. A list of laboratories can be found at http://www.astm.org.
- Reminder: It is illegal to offer to sell or to sell a motor fuel that does not met the state standards for quality. Employees should know what action to take if a problem occurs when management is not at the location.
- Reminder: When selling ethanol containing gasoline you must have a suitable 10 micron filter in place.
- Keep your pumps properly labeled at all times to allow the customer to make the proper product selections. The Motor Fuels Quality Act requires that every retail motor fuel dispenser be labeled as follows:
- That the product "MEETS MICH. QUALITY AND PURITY STANDARDS FOR" (Not less than 24-point type size Helvetica font).
- The name of one of the state standardized grade names. (Not less than 48-point type size Helvetica font).
- "SUBREGULAR" for an 85 or 86 octane product
- "REGULAR" for an 87 octane product
- "MIDGRADE 88" for an 88 octane product
- "MIDGRADE 89" for an 89 octane product
- "PREMIUM" for a 90 octane product
- "PREMIUM 91" for a 91 octane product
- "PREMIUM 92" for a 92 octane product
- "PREMIUM 93" for a 93 octane product
- "PREMIUM 94" for a 94 octane product
- "ULTRA LOW SULFUR HIGHWAY DIESEL FUEL"
- "LOW SULFUR HIGHWAY DIESEL FUEL"
- "NON HIGHWAY DIESEL FUEL"
- A list of Methanol additives present in amounts of one percent or more. Example: METHANOL 5%.
- CONSUMER COMPLAINTS TOLL-FREE HOTLINE" (Not less than 10-point type size Helvetica font). "CALL 1-800-MDA-FUEL" (Not less than 24-point type size Helvetica font).
- Uppercase Helvetica, medium typeface of identical color shall be used. The notice must be placed between 34 and 78 inches from the driveway elevation on every side of the dispenser that has a price computation or quantity display panel. The grade name must be in close association with the brand name, the associated pump nozzle, or the unit price for the corresponding grade. Items a) and d) may be listed only once on each side of a multi-product dispenser provided all other requirements are met.
NOTE: Labeling requirements for Biodiesel and Biodiesel blends may be referenced in http://dmbinternet.state.mi.us/DMB/ORRDocs/AdminCode/198_10185_AdminCode.pdf
- Keep extra labels on hand in the event they become worn, removed, or defaced.
- All diesel fuel dispensers must be clearly and conspicuously labeled to prevent customers from dispensing diesel fuel into gasoline engine vehicles. In some cases a diesel label on the nozzle housing itself would be beneficial. A larger diameter nozzle may also be used.
- In addition to these requirements, the Federal Trade Commission requires the posting of the yellow and black Anti Knock Index (octane) stickers. The Federal Trade Commission sticker should not be in conflict with the state standardized grade name stickers.
- Reminder: All motor fuel products must be labeled with the correct grade name at all times.
- Make sure the price on your roadside sign is in agreement, including the tenths of a cent, with the price displayed on the pump. Do price changes so the higher price is the one on the roadside advertisement. When the price goes up change the sign first. When the prices go down, change the dispenser first.
- Keep your pumps properly calibrated and in good working order. If you have a computerized blend system make sure you have the correct blend ratios for the products you are receiving. Replace worn or damaged parts, especially in blending and single hose pumps. Failed check valves can cause product contamination.
- Keep track of inventory levels and compare them to sales volumes to help identify if your blend pumps are malfunctioning. Shortages or overages in tank inventory may signal a problem.
NOTE: You, as the licensed retail outlet, have the final responsibility for the quality of the motor fuel you sell to your customers. Maintain good records and keep those records on site for department review if requested. Monitor all deliveries made to your location. Take immediate corrective actions when a mistake occurs.
