Every major NZ rental company's misfuel policy, excess charges, and contact numbers. The short version: almost none of them cover it. You need to act fast.

24/7 — Drains the tank before the engine does the damage

Do NOT start the engine — this is the single most important thing

With a rental car, wrong fuel is already your financial liability. Starting the engine makes the damage exponentially worse. Recovery before the engine is started is itemised per our rate card and is usually far less than engine repair on a modern diesel (see rate card–see rate card). In a rental car, that is your bill, not theirs.

Why Rental Car Misfuel Is Different to Your Own Car

With your own car, your comprehensive insurer (AMI, State, FMG) might cover the cost. With a rental car, you are dealing with the rental company directly — and they are not your friend in this situation.

Most NZ rental T&Cs explicitly exclude wrong fuel from all insurance and excess protection products
Even "zero excess" policies (GO Peace of Mind, JUCY Stress Free Plus) do not cover wrong fuel — it is a listed exclusion
LDW (Loss Damage Waiver) covers accident damage — wrong fuel is not an accident, it is driver negligence, and is treated differently
Travel insurance with rental car excess cover MAY help — check your policy carefully
Calling Eek before starting the engine is the single best thing you can do — it caps the cost at the extraction fee

What to Do Right Now — Rental Car

  1. 1
    Stop fuelling immediately — do NOT start the engine

    Every second counts. Move the vehicle to safety without starting the engine if possible (push it, or ask for help).

  2. 2
    Call Eek: (866) 777-3712

    We come to you. We drain the tank, flush the system, and refuel. Average 45 minute response. This is the single action that prevents a minor misfuel becoming a major repair bill (see rate card).

  3. 3
    Call your rental company's roadside number

    Notify them of the incident as required by your agreement. Get a reference number. Do not admit fault in any way that could be used against you — simply report the situation factually.

  4. 4
    Get the Eek incident report

    Our report documents the contamination type, how much was extracted, what was flushed, and the condition of the fuel system. This is your evidence if the rental company makes a damage claim.

  5. 5
    Check your travel insurance

    Some comprehensive travel insurance policies include rental car excess cover. If yours does, lodge a claim. The Eek invoice and report is the documentation your travel insurer needs.

Full Liability — Wrong Fuel Is Explicitly Excluded

These companies explicitly exclude wrong fuel from their insurance and excess protection. You pay the full cost of extraction and any resulting damage.

Enterprise Rent-A-Car

Renter liable — check agreement

Varies by location and coverage purchased

Wrong fuel policy:

Enterprise rental agreements typically hold the renter responsible for damage caused by using the wrong fuel. Optional damage waivers may not cover operator error or contamination — read your rental contract and state addendum.

Damage waiver products often exclude misuse, negligence, and improper fueling. Do not assume LDW/CDW covers misfuel remediation.

What to do:

Do not start the engine. Call Enterprise Roadside Assistance on your rental agreement. Then call EEK to perform USIFDA-certified fuel extraction before damage escalates.

Hertz

Full repair liability likely

Repair and towing costs per rental agreement

Wrong fuel policy:

Hertz terms require renters to return vehicles in the same condition and use the correct fuel. Wrong fuel is generally treated as renter-caused damage, not a mechanical breakdown covered by optional protection plans.

Loss Damage Waiver and similar products typically exclude damage from improper fueling. Roadside may tow but not perform certified fuel system recovery.

What to do:

Do not start the engine. Call Hertz 24/7 roadside (number on your contract). Then call EEK immediately for extraction and documentation.

Avis

At-fault fees + repair costs

Roadside fee + damage up to rental excess

Wrong fuel policy:

Avis Budget Group terms treat incorrect fuel as renter negligence. Protection products may limit collision damage but often exclude fuel contamination and resulting engine or fuel system repairs.

Optional roadside packages may cover a service call — not the full cost of professional misfuel recovery or engine damage if the vehicle was driven.

What to do:

Do not start the engine. Call Avis roadside assistance. Then call EEK to drain and flush the tank with claim-ready documentation.

Budget

At-fault fees + repair costs

Wrong fuel policy:

Budget (Avis Budget Group) uses similar terms to Avis. Wrong fuel is typically an at-fault renter charge including extraction, cleaning, and any component damage.

LDW reduces collision excess but usually does not waive wrong-fuel remediation costs.

What to do:

Do not start the engine. Call Budget roadside per your agreement. Then call EEK before starting the vehicle.

National Car Rental

Renter liable — check agreement

Wrong fuel policy:

National (Enterprise Holdings) rental contracts generally make the renter responsible for damage from improper fuel use. Emerald Club benefits do not replace contractual fuel obligations.

Review your rental agreement fuel and damage sections before relying on any waiver product.

What to do:

Do not start the engine. Use the roadside number on your rental jacket. Call EEK for certified extraction.

Alamo Rent A Car

Renter liable — check agreement

Wrong fuel policy:

Alamo terms require correct fuel use. Misfuel incidents are typically billed to the renter including third-party recovery and mechanical remediation.

Optional coverage may not apply to contamination or operator error — confirm at pickup if unsure.

What to do:

Do not start the engine. Call Alamo roadside. Then call EEK — fast extraction limits your exposure.

Check Your Rental Agreement

No public wrong-fuel policy found — check your agreement directly with the company.

Sixt

Check your rental agreement

Wrong fuel policy:

Sixt US terms vary by location. Wrong fuel is commonly excluded from protection packages and charged as renter-caused damage.

Read the fuel and misuse clauses in your specific contract — airport vs. neighborhood locations can differ.

What to do:

Do not start the engine. Contact Sixt using the number on your agreement. Call EEK for immediate extraction.

Turo (peer-to-peer)

Depends on protection plan

Wrong fuel policy:

Turo trips are governed by the platform protection plan selected (Minimum, Standard, or Premier) plus the owner's listing terms. Wrong fuel may be treated as renter-caused mechanical damage — coverage limits and deductibles apply.

Document everything and contact Turo support immediately. Owner disputes are common — professional EEK documentation helps.

What to do:

Do not start the engine. Message the host and open a Turo incident. Call EEK for extraction before the engine runs.

Travel Insurance and Rental Car Excess Cover

Some comprehensive travel insurance policies include rental car excess cover. If yours does, the process is: the rental company charges you the excess — you then claim that excess back from your travel insurer. This does NOT apply if the rental company treats wrong fuel as a T&C breach (voiding all cover) rather than a damage event attracting the standard excess.

The Eek invoice and technical incident report is what your travel insurer will ask for to validate the claim. We provide it as part of every job.

Travel insurance policy wording varies significantly. Read yours carefully — specifically look for clauses on rental car excess cover and any exclusions for driver negligence or incorrect fuel use.

What the Eek Report Includes

When you use Eek, you get a complete technical incident report that documents:

Vehicle registration, make, model, VIN
Date, time, and location of the incident
Type of contamination (petrol in diesel etc.)
Gallons extracted and correct fuel added
Engine start status at time of callout
Components inspected: fuel pump, injectors, filters
Work performed: drain, flush, system test
Full itemized invoice with cost breakdown

This report is formatted for insurer and rental company assessment — exactly what you need if you are disputing damage charges or submitting a travel insurance claim.
