Managing fuel costs and paperwork can be tough for mechanics and mobile services. Fuel cards make it easier to save, track spending, and streamline admin. Find out how a card like CardSmart can help your fleet save time and money, all while keeping you on the road.
What Are the Main Fuel Card Benefits for Mechanics and Mobile Auto Services?
1. Save Money on Every Fill-Up
Fuel cards offer discounts on petrol and diesel that can really add up, especially for busy mechanics and mobile auto services. For instance, CardSmart gives you up to 15c off per litre at Mobil, and offers great deals at BP, Caltex, Z Energy, and more. Other cards like Z Business Fuel Card, BP Fuel Card and Driveline Fuel Card offer 8-9c/l off petrol and diesel. Even small savings can add up to big money over the year, especially if you have a small fleet.
2. Simplify Admin and Bookkeeping
Fuel cards automatically track every purchase, so you get one easy-to-read invoice to handle GST claims and taxes. No more dealing with faded receipts or sorting through personal and business expenses. Most cards, including CardSmart, even integrate with accounting software, giving you detailed reports to keep track of spending and spot any trends.
3. Set Personalised Controls and Security Features
Fuel cards let you set spending limits, so you can restrict purchases to fuel or vehicle services only – like WoF, servicing, or tyres. You can assign cards to specific vehicles or drivers, and set PINs for extra security. Plus, some cards let you require odometer readings to help prevent fraud and make it easier to track who’s spending and where.
4. Improve Cash Flow
Fuel cards often offer interest-free credit periods. For example, CardSmart lets you pay in up to 51 days. This gives you extra time to pay, which can really help with cash flow—whether you’re going through a busy patch or a quieter one. Plus, flexible payment options like direct debit or credit card give you more ways to stay on top of your costs.
5. Help with More Than Just Fuel
Some cards, like CardSmart, can be used for more than just fuel. They cover things like vehicle servicing, repairs, WoF tyres, and even purchases at places like Bunnings or locksmiths. This is super handy for mechanics and mobile services who need to keep their vehicles running smoothly without juggling different payment methods. Other cards might offer rewards or discounts at tyre retailers or accessory shops.

What Should You Look for When Choosing a Fuel Card?
Discount Type: Is it off the pump price or a national price? Make sure you know what the ongoing rates will be after any introductory deals.
Network Coverage: Check that the card works where you do business – whether it’s nationwide or just in certain regions.
Fees: Look for hidden costs like monthly fees, transaction fees, and payment surcharges that might eat into your savings.
Payment Terms: Longer credit periods can help with cash flow, but make sure there are no extra fees if you use a credit card to pay.
Extra Benefits: Some cards offer rewards, partner discounts, or options for non-fuel spending—this could be a huge time-saver for busy mechanics.

FAQs
Can I use a fuel card for personal vehicles?
Fuel cards are generally intended for business use, but some providers allow personal use too, though you’ll need to keep track of those purchases separately. If personal fuel usage is mixed with business use, you may have to report it for tax purposes. Always check with your provider for details.
How long does it take to get approved for a fuel card?
Most fuel cards are quick to approve, typically within a few business days. Once you’re approved, you’ll usually receive your card within a week, so you can start using it right away.
Can I track fuel usage by vehicle or driver?
Yes! Many fuel card providers allow you to set up individual cards for each vehicle or driver, so you can track fuel consumption separately. This makes it easy to spot any unusual spending and helps with budgeting and reporting.
Are there limits on how much I can spend with a fuel card?
Yes, many fuel cards allow you to set daily, weekly, or monthly spending limits. You can also control what the card can be used for—like fuel only, or include vehicle services, tyres, or other approved expenses. This gives you greater control over spending.
What happens if my fuel card is lost or stolen?
If your card is lost or stolen, you should report it to the provider immediately. Most providers will block the card to prevent any unauthorised use and issue a replacement card. Some may charge a small fee for this service.
Are there any fees for using fuel cards?
Some fuel cards have a fee, such as a monthly account fee or transaction fee. These fees vary by provider, so it’s important to read the terms and conditions carefully to avoid surprises. Some cards also offer promotional periods where fees are waived or reduced.
*Fuel discounts and any fees listed are indicative only and subject to change. Actual savings often depend on factors such as business usage, monthly spend, card type, and provider terms. Always check with your chosen fuel card provider for the most up-to-date rates and eligibility criteria.
