Your Free Fuel Efficiency Check
Was your car made after 1996?
All vehicles manufactured after 1996 have an OBD2 port — the same port mechanics use to diagnose your engine.
✓ If yes: your car is compatible with FuelfixPro.
Do you fill up more than once a week?
High fill-up frequency is a strong indicator your engine’s fuel mapping isn’t optimised for your driving patterns.
⚠ If yes: you’re likely losing $40–$80/month to inefficient combustion.
Has your fuel economy gotten worse over time?
Engine ECU settings drift over time. Without recalibration, most vehicles lose 10–20% fuel efficiency within 3–5 years of ownership.
⚠ If yes: your ECU almost certainly needs optimisation.
Do you drive mostly city roads or stop-start traffic?
Stop-start driving is where factory ECU settings perform worst. FuelfixPro adapts specifically to your driving pattern — city drivers typically see the biggest gains.
⚠ If yes: you’re in the highest-saving driver category.
Has your car ever had a professional ECU remap?
A dealership remap costs $400–$800 and achieves similar results to FuelfixPro — but it’s permanent, voids warranties, and requires a garage visit.
✓ If no: FuelfixPro gives you the same benefit for $38.99, in 30 seconds, at home.
