FAQs » Fuel Caps » Mazda

Why you shouldn't buy and fit a Cheap Petrol Cap to your Mazda

Fitting a cheap fuel cap to your Mazda is not recommended. Because all Mazda filler caps are NOT created equal. Many sold online in the UK are cheap imports from the Far East. Ask yourself how they could sell at half the price you might expect to pay on the High Street or from a specialist online seller like us.

But, it's only a petrol cap. Your fuel cap is part of your MOT inspection. It keeps the fuel from spilling out of the tank, should you be involved in an accident. It has to maintain pressure within the fuel tank itself. You wouldn't replace your brakes or steering wheel with a cheap import made from low grade plastics.

Because all our Mazda fuel caps are produced in Europe, to ISO 9001 specification, you know you are fitting a safe, well-made product to your vehicle.

customer service reviews

5 ***** service...

Bernadette | England

Hi just wanted to say thank you for having a diesel cap to fit our old Campervan L reg!!!! We‘d been hunting for a while! So the other night I decided to investigate further & to my surprise came across The Fuel Cap Company...... I was thrilled to discover a company devoted to the subject..... I emailed immediately to wake up to an early morning response..... a few photos later of the fuel opening they responded with a suggested cap! I promptly ordered & it arrived free post we are now legal with a fully fitted lockable cap!!!! Thank you so much for your 5 ***** service I'll be recommending Mark & his company!!!
