I dropped my Mercedes petrol cap
I dropped my Mercedes petrol cap knocking the inside part out of line. With so many caps available for the Mercedes l gave up looking, contacted Mark at Petrolcap. As it wasn't broken he thought we could save it. So l sent photos and he talked me through fixing it. Thank you so much Such a lovey man to talk to.
I found it very easy to order the replacement petrol cap I needed for my car, from my mobile phone and it arrived very promptly. Well packaged with clear labelling and instructions. Thank you very much.
Extremely satisfied customer...

about the fuel cap company
A family run business built on trust and service since 2007
The Fuel Cap Company was born out of necessity. Like so many other businesses, it all started when sourcing a quality replacement fuel cap for a friend proved to be far from easy. That was back in 2007. We have been supplying quality fuel caps to our customers ever since. Although the UK remains our largest market, we ship fuel caps all over Europe, to India and Australia and the US and Canada. In fact over the years, we have shipped to over 35 countries from our head office in Oswestry.
Buying from us, you can be assured you are buying a quality product (ISO 9001), manufactured in Europe to OEM standards, from a family run business that thousands of buyers all around the world have come to trust.
