Fuel Additives
A fuel additive is a product added to the fuel tank, and its claims vary by product. Our pages on specific products are listed below.
Last updated: 20 October 2026
How we research fuel additives
- Each page summarises the maker’s page and a UK retailer listing, with the date we checked it.
- We search GOV.UK product safety alerts, reports and recalls for the brand and say what we found.
- We have not tested these products ourselves, and we mark anything we could not verify.
What to check on each page
- Which fuel it is for (petrol or diesel), the dose per tank, what the maker claims and any warnings.
- Whether the page names the exact model, because makers sell many variants under one name.
