2015 Mazda 6 2.2L Diesel · LR15 CCF

As a 2191cc diesel, this Mazda 6 should return strong fuel economy, typically 50-60 mpg in mixed driving, keeping fuel costs modest for a large family car. Road tax for a 2015 diesel of this size usually falls in the higher bands due to CO2, and insurance groups for the Mazda 6 diesel are mid-range, so premiums are moderate.

Maintenance costs are generally reasonable for the model, but the 2.2 diesel can incur higher bills for DPF or emissions work if used mainly on short trips. Based on the mileage and noted wear, we estimate annual running costs at £1,000-£1,300 including fuel, tax, insurance, and typical servicing plus consumables.

On this specific vehicle, closely inspect the front braking system and tyres first, as the November 2025 failure recorded Nearside and Offside Front brake pads less than 1.5mm and tyres worn to 2mm on the edge; verify the replacement parts are in good condition and not just minimally compliant. Check that brake performance can be demonstrated, given the original test could not measure it.

Examine both rear lower suspension arms for corrosion progression, since the March 2024 MOT noted mild corrosion on both sides. Also look under the car at the centre exhaust noted as rusty in March 2023, and confirm the undertray fitted at the same test is still secure and not hiding leaks or damage.
