Is My Car Compatible With E10 Petrol? How to Check
Cars built since 2011 all take E10. If yours is older it comes down to the make, and the official checker won't even ask for your number plate.
7 minRunning a car
What a used car really costs to keep on the road, which cars hold their value, and where you stand when a garage bills you for work that didn't fix it.
The cost of running a car arrives at different speeds, and the biggest one never sends a bill.
Fuel and insurance you feel monthly. Servicing arrives a few times a year. Depreciation takes the largest share of all and shows up only when you sell. Running costs of a used car puts real numbers against all of it, and depreciation explained covers which cars hold their value and why.
Maintenance is where a used car is won or lost. Common faults by age sets out what tends to break and roughly when, which is useful both for budgeting and for deciding how old a car to buy. What a full service history really means matters more than the phrase suggests. Plenty of cars advertised with one have gaps in exactly the wrong places.
Fuel grade is a smaller worry, and an easy one to settle. Is my car compatible with E10 petrol? covers the official checker, the ordinary early-2000s cars that get caught out, and what to do if you have already filled up.
Fuel tax is the quietest line of the lot. The 2026 fuel duty rise explains why September's increase never happened, and what the rate is now. It also works out what the next step actually costs you.
Cover is the other half. Used car warranties explains the types, what they routinely exclude, and when one is worth buying at all. Wear items are the usual exclusion, and they're also the usual failure.
Two more guides deal with the paperwork and the arguments. Keeping your V5C updated covers the changes DVLA needs to hear about. When a mechanic didn't fix your car covers where you stand on a bill for work that didn't work, including the lien that lets a garage keep your car.
Servicing raises its own question. Do you have to use a main dealer to keep the warranty? sets out what the competition rules actually protect. It is less than the usual headline suggests, and there are places a manufacturer can still say no.
Most of this is cheaper to plan for than to react to. That's the whole argument for reading any of it early.
