2012-2018 Ford Focus Hatch & Sedan Maintenance and Cost
The Focus' minor services happen every 10,000 miles, and these are little more than an oil and filter replacement and a series of checks. At 20,000-mile intervals, the cabin air filter ($32) must be replaced, and every 30,000 miles, the engine's air filter ($24). A typical 60,000-mile service where all these items would require attention costs in the region of $550 at Ford and $385 at an independent shop on the 1.0-liter turbocharged engine and around $620 and $450, respectively, on the 2.0-liter engine. If you use your Focus in severe conditions, such as sub-zero temperatures or in dusty conditions, or if it idles for prolonged periods, reduce the oil-change interval to 5,000 miles and halve the replacement intervals of the filters too. The cooling system should be drained, flushed, and refilled at least every 100,000 miles. The PowerShift automatic transmission does not require frequent oil changes like dual-clutch automatics usually do, because its dry clutches do not sit in the transmission oil and cannot contaminate it.
The timing chain in the 2.0-liter engine should be maintenance-free for a long time as long as the engine receives clean oil frequently. The 1.0-liter three-cylinder uses a wet timing belt that runs in engine oil, and this is said to be good for 120,000 miles or ten years, whichever comes first, depending on the vehicle the engine is fitted to. However, lax maintenance, deferred oil changes, and contaminated oil may all have an effect on the belt and we'd rather not leave it for longer than 100,000 miles, just to be safe. Neither engine has hydraulic valve lifters, so periodic adjustment of the valve clearances will be necessary, typically at around 75,000 miles. For information about the correct wiper blades, tire size, or battery rating, just consult the owner's manual or ask your dealer. The only gas type these high-compression direct-injection engines want is premium.
