It depends on the policy
Some comprehensive policies include misfuel cover. Many exclude it, cap it, or only pay for damage and not the drain itself. Some breakdown policies include a misfuel call-out or offer it as an add-on.
What to check
Look for 'misfuelling', 'wrong fuel' or 'contaminated fuel' in your policy wording. Check the excess — on a small claim it may be more than the drain costs. Check whether a claim affects your no-claims discount.
Paperwork that helps
An itemised receipt, the job report from the technician, your fuel receipt and photos. We supply the report and receipt as standard.
