Who We Are
CarCompatibility.com is an independent UK resource helping car owners find the right parts and consumables for their vehicles.
This site is funded through affiliate marketing partnerships, particularly with Amazon Associates. We are not owned by, endorsed by, or affiliated with any car manufacturer or major retailer.
Our goal is to provide helpful, accurate, and unbiased guidance on car maintenance — and to make it easy to purchase the parts you need.
What Is Affiliate Marketing?
Affiliate marketing is a simple business model:
- You visit our Site and read our guides about wiper blades, engine oil, or other consumables
- We provide a link to Amazon where you can purchase the recommended product
- If you click the link and make a purchase, Amazon credits us with a small commission
- You pay the normal Amazon price — you don’t pay any extra
Why Do Websites Use Affiliate Links?
Creating high-quality guides, compatibility databases, and comparisons requires time, research, and hosting costs. Affiliate commissions help us:
- Keep the Site free to use (no paywalls or subscriptions)
- Update guides regularly with the latest products
- Maintain accurate compatibility data for 67+ UK car models
- Add new consumable types and guides
- Cover web hosting and technical maintenance
Without affiliate revenue, we would need to charge a subscription fee or display excessive ads.
Amazon Associates Programme
CarCompatibility.com is a participant in the Amazon Services LLC Associates Programme, an affiliate advertising programme designed to provide a means for websites to earn advertising fees by advertising and linking to Amazon.co.uk.
What We Link To
We link to Amazon products in these scenarios:
- Product recommendations: When we recommend a specific brand of wiper blades or engine oil, we include an Amazon link
- Product comparisons: In our guide comparing different oil grades, links help you view the options on Amazon
- Tool resources: Links to tools needed for car maintenance
- Learning materials: Books and videos about car maintenance
We do not:
- Link to every product on every page just to earn commissions
- Recommend products we don’t actually believe in
- Hide or disguise affiliate links (we’re transparent)
- Prioritise products based on commission rates

How We Benefit from Affiliate Links
Commission Structure
Amazon Associates pays us a commission on qualifying purchases. Commission rates vary by product category (typically 1–10%), but are set by Amazon — we have no control over these rates.
We don’t know your personal details, purchasing history, or how much you spend. We only see:
- That a visitor from our Site made a purchase
- The general product category (e.g., “Automotive”)
- Approximate commission amount
Commission Timeframe
Amazon affiliate links are valid for up to 90 days. This means:
- If you click our link today but purchase next week, we still earn a commission
- You can add items to your cart over several days and complete the purchase within the 90-day window
What Qualifies for Commission
Not all Amazon purchases generate commissions for us. Commission is typically earned on:
- Physical products (wiper blades, oils, filters, batteries, spark plugs)
- Most automotive parts and tools
- Approved product categories
No commission is earned on:
- Digital products (e-books, apps)
- Certain restricted categories (alcohol, weapons, etc.)
- Amazon Prime memberships or services
No Impact on You
Your Benefits
In fact, using our affiliate links may benefit you:
- Easy access: You don’t need to search Amazon yourself for the right part
- Confidence: We’ve already verified that the product fits your car
- Comparison: Our guides often compare 3–5 options so you can choose
- Reviews: You can see Amazon customer reviews before purchasing
- Warranty: Amazon’s standard returns policy applies as normal
Alternative Options
You don’t have to use our links. You can:
- Go directly to Amazon.co.uk and search for the product yourself
- Buy from other retailers (Halfords, Eurocar Parts, local garages, etc.)
- Use a different affiliate link from another website
- Support us without clicking our links — our guides are free and helpful regardless
Our Editorial Integrity
How We Choose What to Recommend
Our recommendations are based on:
- Specifications: Does it fit your car? (compatibility data from manufacturer handbooks)
- Quality: Reputable brands with good customer reviews
- Value: Good price-to-quality ratio
- Availability: Is it in stock on Amazon UK?
We do not recommend products based on commission rates. Amazon’s commission structure is the same regardless of which product we link to, so we have no financial incentive to push one brand over another.
Honest Reviews
We read customer reviews on Amazon and mention both positives and negatives. If a highly-recommended product has consistent complaints, we’ll mention that. Our job is to help you make an informed decision, not to simply drive clicks.
Multiple Options
We typically recommend 3–5 options for each consumable type so you can compare and choose what suits your budget and preferences.
Why We’re Transparent About Affiliate Links
We believe you deserve to know how we make money. Being transparent:
- Builds trust: You know exactly how the business works
- Explains our incentives: You can evaluate our advice with this knowledge
- Complies with regulations: UK GDPR, Consumer Protection from Unfair Trading Regulations, and Amazon’s terms require disclosure
- Respects your intelligence: You’re capable of understanding affiliate marketing and deciding whether to use our links
Legal Requirement
Under UK law, we must disclose affiliate relationships. This is to:
- Protect consumers from undisclosed advertising
- Ensure you can evaluate the credibility of our recommendations
- Maintain fair competition in online retail
We take these requirements seriously because we believe transparent business is good business.
