Terms of Sale

Last updated: 27 July 2026

These conditions govern every sale of Fuelnox by Fuel Set EU S.L. (B27678390), whose details appear in the Legal Notice. Please read them before you order. By placing an order you accept them.

1. Who these terms apply to

They apply to two kinds of buyer, and several clauses treat the two differently:

• A consumer is an individual buying outside any trade, business, craft or profession. Consumers have the mandatory rights described below, and nothing in these terms reduces them.
• A business buyer is anyone buying in the course of a trade, business, craft or profession, including sole traders and workshops. Business buyers do not have a right of withdrawal or a consumer legal guarantee, and the clauses on notification of defects, liability and jurisdiction apply to them in the stricter form set out below.

You tell us which you are when you order, by giving or not giving a company name and VAT number. If you give business details, you are treated as a business buyer.

2. How an order is placed

Orders reach us by one of two routes:

• Online shop. You add the product to the basket, enter your delivery and billing details, see the total price including VAT and delivery before confirming, tick to accept these terms, and pay. The step marked as confirming the order is the step that creates a payment obligation.
• By email or on a quotation. Mainly for business and larger orders. We issue a proforma invoice or a written quotation setting out product, quantity, price, taxes, delivery cost and lead time. Your written acceptance of it, or its payment, constitutes your order.

Your order is an offer to buy. The contract is concluded only when we send you an order confirmation by email, or, if earlier, when we dispatch the goods. An automatic acknowledgement that we have received your order or your payment is not an order confirmation.

3. Our right to decline an order

We may decline or cancel any order, in whole or in part, before dispatch. We will tell you why where we can, and we will refund in full and without delay anything you have already paid. We may do this in particular where the product is unavailable, where we cannot deliver to your address, where the price or product description contained an obvious error, where we have reason to believe the order is for resale into a market where the product is not authorised, where the order appears fraudulent, or where supplying you would breach applicable law.

Obvious errors. If a price or a product characteristic shown at the time of your order was clearly wrong, and the error would have been evident to a reasonable buyer, we are not obliged to supply at that price. We will contact you to confirm the correct price or cancel and refund.

4. Age, hazard information and safe use

Fuelnox is a chemical mixture classified as hazardous under Regulation (EC) 1272/2008 (CLP). Signal word: Danger. H302 Harmful if swallowed. H315 Causes skin irritation. H318 Causes serious eye damage. H371 May cause damage to organs. H412 Harmful to aquatic life with long lasting effects. Keep out of reach of children.

We do not sell to anyone under 18, and by ordering you confirm that you are 18 or over. The full safety data sheet is available free of charge on request at Email us, and is supplied with professional and business orders. You must read the product label and the safety data sheet before use, and use, store and dispose of the product in accordance with them. They prevail over anything published on this website.

5. Prices, VAT and invoices

• Prices are in euros. Prices shown to consumers include the applicable VAT. Prices quoted to business buyers may be shown net of VAT, in which case VAT is added at the applicable rate before payment.
• Delivery costs are not included in the product price. They are shown separately before you confirm the order.
• For consumers in Spain, Spanish VAT applies. For consumers elsewhere in the EU, VAT is charged at the rate of your country under the One Stop Shop regime. For business buyers in another EU member state with a VAT number valid on VIES, the supply is reverse charged and shown without Spanish VAT; if the number proves invalid, we may reissue the invoice with VAT and claim the difference.
• The Canary Islands, Ceuta and Melilla sit outside the EU VAT and customs territory. Orders to those territories are handled separately, on request.
• Invoices are issued electronically and sent by email. We do not send printed invoices.
• Prices may change at any time, but the price applying to your order is the one shown when you placed it.

6. Payment

Online payments are handled by Mollie B.V., a regulated payment institution in the Netherlands, which accepts the methods shown at checkout. We never see or store your full card number. Business orders may also be paid by bank transfer against a proforma invoice; those goods are reserved but not dispatched until the funds have cleared.

Retention of title. The goods remain our property until we have received payment in full. Risk passes as set out in the Shipping.

Late payment by business buyers. Where we have agreed payment terms with a business buyer and payment is late, interest accrues automatically at the rate set by Spanish Law 3/2004 on late payment in commercial transactions, together with the fixed recovery sum of 40 euros provided for in that law, without any need for a reminder.

7. Delivery

Delivery is covered in full in the Shipping, which forms part of these terms. In summary: we ship within Spain with NACEX and to the rest of the European Union with DHL; delivery cost and estimated lead time are shown before you order; and in no case will delivery exceed 30 calendar days from conclusion of the contract without your agreement.

8. Withdrawal, returns and refunds

Consumers have a 14 day right of withdrawal, subject to one important exception for sealed containers that have been opened. The full rules, the exception and the withdrawal form are in the Returns, which forms part of these terms. Business buyers have no right of withdrawal.

9. What we do and do not promise about the product

Fuelnox is supplied to the specification described on its label and in its technical documentation, and it will be of the quality and composition stated there. That is the promise we make.

What we cannot promise is a particular outcome in your engine. Descriptions on this website of cleaner combustion, easier starting, smoother running, reduced smoke, restored power or improved fuel economy describe what the product is designed to do and what users typically report. They are not a guarantee, a warranty, or a contractual specification of performance. Results depend on the engine, its condition and service history, the fuel, the dosage used, the operating pattern and other factors outside our control. No statement about performance, savings or consumption forms part of the contract, and no claim may be made against us on the basis that a particular improvement was not achieved.

Statements that the product is compatible with vehicles under manufacturer warranty describe the product's composition, which is free of the substances that typically void such warranties. They are not an undertaking on behalf of any vehicle manufacturer, and we cannot control the position a manufacturer or dealer takes in an individual case.

Fuelnox is not for use in aviation fuels, and is not to be used for any purpose other than conditioning the fuel systems it is described for.

10. Guarantees

Consumers. We are liable for any lack of conformity of the goods that becomes apparent within three years of delivery, under Royal Legislative Decree 1/2007. Any lack of conformity appearing within the first two years is presumed to have existed at delivery unless the contrary is shown. The remedies, in order, are repair or replacement, and then price reduction or termination of the contract. The action to enforce them lapses five years after the lack of conformity became apparent. These rights are free of charge and additional to any commercial guarantee.

Business buyers. Article 336 of the Spanish Commercial Code applies. You must examine the goods on delivery and notify any apparent defect, shortage or damage within eight calendar days, and any hidden defect within thirty days of delivery. After those periods the goods are deemed accepted. Our sole obligation for a defective product supplied to a business buyer is, at our option, replacement of the product or refund of its price.

What no guarantee covers. Any guarantee excludes: product used other than in accordance with its label, dosage instructions or safety data sheet; product stored outside the stated conditions or beyond its stated shelf life; product decanted, diluted, mixed or altered; damage caused by pre-existing mechanical faults, contaminated or out-of-specification fuel, or the condition of the fuel system before use; and normal deterioration of an opened container.

11. Limitation of liability

We are liable for foreseeable loss caused by our breach of these terms. Subject to the paragraph below, and to the fullest extent permitted by law:

• our total liability arising out of or in connection with any order is limited to the price you paid for the goods concerned;
• we are not liable for indirect or consequential loss, loss of profit, loss of revenue, loss of contracts, loss of use, vehicle or vessel downtime, towing, hire of replacement equipment, or loss of data;
• we are not liable for damage arising from use of the product other than in accordance with its instructions, label and safety data sheet, nor for engine or fuel-system damage attributable to pre-existing condition, wear, contaminated fuel or third-party work.

Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for defective products under Royal Legislative Decree 1/2007 implementing the product liability rules, or for any other liability that cannot lawfully be excluded. Nothing in these terms affects the mandatory rights of consumers.

12. Resale and correct market

If you buy for resale, you are responsible for complying with the law of the market into which you resell, including labelling, language, classification, packaging and any registration requirement, and for passing the safety data sheet and hazard information down the supply chain. You may not resell the product outside the European Union without our written consent, and you may not repackage, relabel or rebrand it.

13. Events outside our control

We are not liable for failure or delay in performing our obligations where that failure or delay results from an event outside our reasonable control, including carrier failure, industrial action, extreme weather, fire, flood, epidemic, interruption of transport or energy networks, failure of public or private telecommunications networks, or acts of government. Where such an event lasts more than 30 days, either of us may cancel the affected order and we will refund what you have paid for it.

14. Personal data

Data given when ordering is processed to conclude and perform the contract, to invoice, to meet our accounting and tax obligations and to answer any related enquiry. Full details, including the carriers and payment provider that receive your data, are in the Privacy.

15. Complaints and dispute resolution

Write to us first at Email us. We answer complaints within one month. Official complaint forms (hojas de reclamaciones) are available to consumers at our registered address and by email on request.

We are not currently signed up to any consumer arbitration board, so we are not obliged to submit to arbitration, though we may agree to it case by case. Please note that the European Commission's Online Dispute Resolution platform ceased operating on 20 July 2025 and is no longer available. Consumers may still contact their local consumer office, or in Spain the municipal or regional consumer information office (OMIC), and retain the right to go to court.

16. Applicable law, jurisdiction and language

These terms are governed by Spanish law. Where you buy as a consumer you also keep the protection of any mandatory rules of the country in which you are habitually resident, and you may bring proceedings in the courts of your own place of residence. Where you buy as a business, the courts of Torrevieja (Alicante, Spain) have exclusive jurisdiction, and both parties expressly waive any other.

These terms are published in several languages. Each version other than Spanish is a translation of the Spanish original. If there is a discrepancy, the Spanish version prevails, except where you contracted as a consumer in one of the other languages, in which case the version in the language in which you contracted applies to you.

17. Other terms

If any clause is held to be invalid, the rest remains in force. Our failure to insist on a term at any time does not waive it. You may not transfer your rights under a contract with us without our written consent. We may update these terms; the version in force is the one published on this page when you place your order, and we keep the applicable version with the order confirmation.
