How to Document Fuel Theft & Prevent Losses

Wright Express Fuel Cards versus Fuelman Fleet Cards for small business

Wright Express  (also known as WEX) has a great article for corporate fuel buyers on the best practices when documenting and confronting fuel theft.

WEX: Tips for enforcing proper fuel card usage and preventing employee theft.

A few things they left out that Star Oilco would include. As a Pacific Northwest Commercial Cardlock provider serving Oregon and Washington, we approach things a little differently than a credit card concept like WEX. We accept and love working with WEX, Voyager, Comdata and other fleet cards but still like personalizing the security of a fuel card to the use of it.  Call your current fuel vendor (or call Star Oilco) and review your security features.  If you suspect there is fuel theft, rather than watch it happen just eliminate the places it can occur. With either CFN or Pacific Pride networks the features are inherit and we can help you guarantee they are being used correctly.

The Four Step Approach to Fuel Card Management

When a customer tells us they suspect fuel theft this is what we recommend to do with either CFN or Pacific Pride cards:

  1. Establish a no tolerance fuel theft policy and have every employee sign it.  This policy includes an acknowledgement by them they have a secret PIN unique to them and if it is used they are responsible for it. So if there is theft with their PIN they can be fired for that theft.
  2. Now that all users of your company vehicles have a unique PIN code. Attache their name to the use of that PIN.  So when you get your fuel bill, the actual names of the users of the cards is there next to the transaction. Just this best practice (and sharing this evidence with your team) will keep honest people honest. If they know their name appears to the transaction they will think about ownership of their actions.
  3. Ensure you have set limits on the cards to line up with the needs of the business.  Attach the fuel cards to the vehicle that uses them.  Then make sure the fuel type and volumes allowed line up with that vehicle. If a vehicle is diesel, that fuel should be the only fuel allowed to be used.  If that vehicle has a 30 gallon or 100 gallon tank set limits so no more than that can be fueled in a given day.  Just limiting the fuel volume to the tank size of a vehicle can eliminate most of the fuel theft that would occur.  Also you can limit the time of day as well as weekends. If a fleet isn’t on the road after 6pm, you can guarantee no fuel theft occurs after 6pm.
  4. Turn over the cards by having all drivers/staff turn in their old cards. Then re-issue those cards attached to the key-rings of the fleet keys.  Star Oilco can provide a card older designed to go on the vehicle key-ring to make this a no cost easy reform.By doing those things which is an easy project you will knock out most of the opportunity for theft as well as send a strong signal to your team that fuel theft is not okay. Honest employees will understanding clearly that theft is occurring and is not okay, the dishonest employees will know to immediately stop.  If theft continues it will also be very easy to spot as the name of the thief will appear on the bill alongside the transaction. That combined with a No Tolerance Fuel Theft policy will make removing the fuel thief an easy proposition for you regardless of your state of operation.If you do business in Oregon and Washington and have questions about securing your fuel purchases.

Stop fuel theft- Pacific Pride fleet cards

Fuel Cards that stop fuel theft with easy to use security controls.

Fuel theft is a very real expense fleets should be thinking about how to avoid.  Every fleet is experience more turn over in their driver pool than they want.  This can cost your business in more than just training expense and overtime.  Add in rising gas prices impacting your entry level employees and an unlocked fuel card is a huge temptation.  Remove the temptation of fuel theft and keep honest drivers honest with Star Oilco’s secure fleet card solution.

Get real time e-receipts when your employees buy fuel with your fleet card.

Having control and real time awareness of what is happening in your small business is a critical piece for growing a successful business. With Star Oilco’s Fleet Cards you can control your fuel cards by only turning them on in the zip codes or states you want to operate in. You can also shut the cards off for weekends and evenings so that when your business isn’t open either is the ability for a dishonest employee to steal fuel.  Our cards also offer real time e-receipts emailing you who is buying fuel where and when enabling your team to reinforce you fuel policies at the moment someone violates it.

Control where, when, and what product can be purchased with your business fleet card.

In Pamona, California two men altered a van to steal thousands of gallons of gas with a stolen credit card.  Credit cards are not designed to secure a business or an individual from fuel theft. Pacific Pride fleet cards are. Especially for corporate or small business fueling.

Similarly in St. Petersberg, Florida an employee used a company fuel card without security controls to steal over $3,000 in gasoline.  Pacific Pride’s controls make this type of theft extremely transparent and easy to get ahead of.

Star Oilco’s Pacific Pride fuel cards can secure your small business from this kind of threat. Be it a special van altered with a giant tank or an employee fueling up his wife’s car while fueling his own company vehicle we can prevent the risk of huge theft.

Pacific Pride Fueling Network Provider

Use a fleet card that sets controls on the gallons that can be bought, time of day, and area of town a card can be used in.

How we do this is with the designed Pacific Pride system which limits your fleet cards to total gallons per transaction, number of transactions a day, time of day, and locations you would actually need fuel. An ounce of prevention is worth a pound of cure. A gallon of restriction literally might be worth tens of thousands of dollars of possible theft. Call us for more information. 503-283-1256

Star Oilco is an Independent Franchisee of Pacific Pride. We are there to make commercial fueling simple for you.  For more information on preventing fuel theft, saving money on fuel, or simplifying your fuel management all you have to do is ask. We want to help.

Portland Retail Fuel Price Variance

Average Oregon gas and diesel prices by fuel grade with current and previous price comparisons

Fuel Market News

Fuel prices are down across the board this past week, as expected with winter fuel blend on the market and oil prices reaching their lowest price point of the year. Rack averages dropped $0.14/gal for gasoline and $0.08/gal for both B5 & B20 diesel. Fuel prices should continue to fall in coming weeks as oil prices are at the lowest price since 2021. Retail prices for fuel in Portland have not dropped much compared to rack averages but this should change in coming weeks as we roll into autumn and winter in the coming weeks. The refinery fires at Chevron’s El Segundo refinery put a temporary bottleneck on supply and prices in previous weeks but have since been resolved as prices continue to fall.

Important Note: Per the City Of Portland, “Distributors in the City of Portland are required to meet the minimum biofuel content requirements for all fuel they distribute beginning on May 15, 2024. All diesel fuel distributed to retail stations, non-retail dealers, or wholesale purchaser-consumers must include a minimum of 15% biofuel content, from either renewable diesel or biodiesel. This requirement increases to 50% on May 15, 2026, and 99% on May 15, 2030”.

Crude Oil is currently trading at $57.60/barrel compared to $59.70/barrel last week and $69 a year ago.

It’s essential to recognize that fuel prices result from a complex interplay of the factors mentioned above and other regional factors.

Fuel prices varied this past week as gas prices increased slightly and diesel prices dipped. Gas prices increased by $0.13/gal on the rack average market and dropped $0.06/gal on the retail street market. Diesel prices dropped $0.10/gal across the board for rack averages, while the retail street average did not move from the week prior. As mentioned in earlier reports, gas prices should come down in the coming weeks with the winter fuel blend back on the market. Fuel prices typically reach their lowest price level from October to December every year. We can expect the same in the coming weeks. Oil prices are also currently below $62/barrel, which will help contribute to lower prices.

Portland Retail Fuel Price Variance

Oregon average fuel prices for regular, midgrade, premium gasoline and diesel with price comparisons

Fuel Market News

Fuel prices trickled down this past week with both wholesale rack averages and retail street prices down. Rack averages in Portland dropped $0.10/gal on E10 gasoline, and dropped less than $0.02/gal on diesel across the board. This trickled down into the retail market as street prices are down about $0.05/gal in Portland. The Olympic Pipeline is back online and the winter-blend of fuel is coming back to the market. We should see prices continue to come down slightly in the coming weeks as winter fuel hits stations across Oregon. Fuel prices typically reach their lowest levels during late fall/early winter every year so we should see downward pricing in the weeks ahead.

Gas prices have trickled back down this week as the Olympic pipeline has been back online and is supplying throughout the PNW. The past two weeks were filled with a massive price jump in gas, with retail averages above $4.50/gal. We should continue to see these numbers fall back this week. Rack averages for Portland are down $0.49/gal for E10 gasoline, while diesel prices did not move more than $0.01/gal. This is the biggest price drop we have seen for gas in months, but it was expected after the Olympic pipeline was offline. As we roll into October, retail stations will switch back to the winter blend of fuel, which may cause a temporary price spike due to logistics, but will be followed by further price dips throughout the market.

Fuel Market News

Gas prices skyrocketed this past week while diesel prices remained stagnant. The maintenance shutdown of the Olympic pipeline caused gas prices to increase by over $0.20/gal in just a week. Diesel prices moved $0.005/gal, with next to no movement on diesel prices. Commuters in Portland saw retail gas prices over $4.50/gal during the past week, and prices have yet to come down. The Olympic pipeline is back online this week, with capacities back to normal. We should see prices fall this coming week with the pipeline maintenance complete and the switch to winter fuel approaching.

Portland Retail Fuel Price Variance

Oregon gas and diesel price averages for regular, midgrade, premium, and diesel fuel comparing current, yesterday, last week, last month, and last year

Fuel Market News

Fuel prices are up across the board this past week, with both diesel and gas jumping over $0.15/gal. Rack averages in Portland jumped $0.20/gal for E10 gasoline and $0.16/gal for diesel. This comes on the heels of the Olympic pipeline maintenance this past week, after issues arose within the pipeline system requiring un-forecasted maintenance. This directly affects supply throughout the PNW, creating pricing bubbles throughout Washington, Oregon & California. Gas prices are expected to continue to climb this week, with maintenance yet to be fully completed. This will also roll into the switch from Summer blends of fuel to Winter blends of fuel, which will begin in the coming weeks. This may temporarily spike prices, with pricing drops thereafter.

Important Note: Per the City Of Portland, “Distributors in the City of Portland are required to meet the minimum biofuel content requirements for all fuel they distribute beginning on May 15, 2024. All diesel fuel distributed to retail stations, non-retail dealers, or wholesale purchaser-consumers must include a minimum of 15% biofuel content, from either renewable diesel or biodiesel. This requirement increases to 50% on May 15, 2026, and 99% on May 15, 2030”.

Reasons For Price Variance

Oil Prices Below $65

OPEC+ Production Boosts For September

Crude oil is trading just below $65, at a current price of $62.35/barrel. This is $2.37/barrel lower than it was last week.

 

Crude oil is the main ingredient for gasoline and diesel. Per AAA, on average about 50% of what you pay at the pump is the price of crude oil, breaking down as 25% refining, 11% distribution & marketing, and 14% taxes – a helpful breakdown for consumers wondering why they are paying the prices that they pay. Crude Oil is currently trading at $62.35/barrel compared to $64.72/barrel last week and $68 a year ago.

It’s essential to recognize that fuel prices result from a complex interplay of the factors mentioned above and other regional factors. Additionally, prices may vary by specific regions within Oregon and Washington.

Open an account with Star Oilco today and prepare for the next power outage.

Recent heat waves might have caused power outages.  Make sure your generators are full for this winter now.  With dynamic changes in the way power is used in the Pacific Northwest power outages have become more common than ever before.

 

Are you prepared for the next emergency?
Have you filled up since the last time?
Would you want to test your diesel fuel oxidative stability to make sure it is still good?

Keeping your back-up generator fueled could be the difference between an inconvenience and a disaster.  Stay ahead of the next emergency and re-fuel now.

 

Remember that ordering diesel for your generator is a specialized service, we will make it easy for you.

Getting the fuel for your generator or emergency equipment is only one part of the problem.  How you store it can be just as important.  This is why its important to work with a company that can help you.

You want to stabilize and treat your diesel for generators and other back up equipment.

Order fuel treated for long term storage!

Star Oilco is an expert at fueling back-up generators, emergency water pumps, and other long term off-road diesel storage requirements. We understand, that in the Pacific Northwest, biodiesel blending is required by state laws. Biodiesel needs an extra layer of care when stored as a back-up diesel fuel.Filling a Generator in the Snow

Most off-road diesels and heating oils are ultra-low sulfur diesel containing at least 5% quantity of biodiesel.  This means long term storage requires a proactive approach.  You can’t just hope it works or wait to see if the fuel will burn after years of storage.

Emergency back-up generator diesel fuel is a specially treated oxidative stabilized off-road fuel designed to store for years.

Fueling a backup generator is a specialized product. The fueling service requires a vendor who understands your needs and keeps you up and running in an emergency.

Generators take off-road diesel, of course, but you want an ultra-low sulfur diesel to ensure it works with modern emission systems. Some companies deliver higher sulfur product that look the same but foul the emission systems of your equipment.

Beyond the service provided, you also want a vendor who offers a fuel stabilizer and biocide for the special long term storage needs of your backup generator. Star Oilco recommends you add a biocide and long-term storage stabilizer to your fuel to ensure it is good whenever you need it.

Use additives designed to prolong the life of your emergency diesel fuel.

Biocides prevent the growth of biological activity in the tank. In scenarios where micro-organisms like algae, bacteria, yeasts, and other bugs are growing in your fuel, biocides kill this growth. It is still important to remove the residual grit and other contaminants that are the hallmark of bugs growing in your tank. Usually, turning over the fuel or using a filtration can remove this.

If your tank absolutely has to be clean, you can contract a tank professional to enter the tank and physically clean the tank bottom or reline the tank with either fiberglass or an epoxy resin. We use Valvtect Bioguard Plus 6 for generators, emergency water pumps, backup boiler fuel, and other long term storage purposes. This product kills any existing biological growth and stabilizes your fresh diesel fuel for long term storage. Make sure your diesel is ready the next time you need backup power.

Water in diesel destroys fuel quality rapidly.

Check your tank for water every fall and spring.

Pumping the tank bottom removes water if it ever finds its way into your storage tank. Additionally, you want to put in an absorbent material designed to absorb water and not fuel. If your long-term storage tank has water and you are not planning to burn 100% of the fuel in the near future, DO NOT add anything that removes water by distributing into the fuel. Adding a “fuel drier” that actually pushes the water into solution with the diesel will worsen the long-term quality of your fuel, not improve it. That water is where bugs find their home to grow in fuel.

Star Oilco will test your fuel at no charge if you have an open account.

Feel free to call us with any questions you may have about long term storage of diesel. Star Oil can also deliver treated diesel ready for long term storage complete with Premium Diesel additive to improve the long-term storage quality of your fuel. For biocide, we use Valvtect BioGuard fuel microbiocide to kill any possible biological activity and prevent any chance of it starting.
