What Oil Does A 2013 Ford Focus Take – The Essential Maintenance
For the standard 2.0L Ti-VCT engine, the 2013 Ford Focus requires 4.5 quarts of 5W-20 synthetic blend oil meeting Ford specification WSS-M2C945-A. If you own the high-performance Focus ST with the 2.0L EcoBoost engine, you will need 5.7 quarts of 5W-30 oil to ensure proper turbocharger lubrication and cooling.
Maintaining a modern vehicle requires more than just a quick trip to the local lube shop. Understanding exactly what oil does a 2013 ford focus take is the foundation of a healthy engine that can easily surpass the 200,000-mile mark.
Whether you are a daily commuter or a weekend DIY enthusiast, using the correct viscosity and specification is non-negotiable for Ford’s advanced engine timing systems. In this guide, we will break down the technical requirements, the tools you need for a home oil change, and the professional tips I have gathered from years under the hood.
By the end of this article, you will have the confidence to handle your own oil maintenance while ensuring your Focus runs as smoothly as the day it left the showroom floor. Let’s dive into the specifics of your Ford’s lubrication needs.
The Standard Answer: what oil does a 2013 ford focus take?
When most owners ask this question, they are looking for the weight and the quantity. For the vast majority of 2013 Ford Focus models (the S, SE, and Titanium trims), the answer is 5W-20 synthetic blend motor oil.
The 2.0L Ti-VCT (Twin Independent Variable Cam Timing) engine is designed with tight tolerances. These internal clearances require a thinner oil like 5W-20 to flow quickly upon startup, especially in colder climates where oil thickening can cause wear.
However, the performance-oriented Focus ST is a different beast entirely. Because it utilizes a turbocharger, it generates significantly more heat, necessitating a slightly thicker 5W-30 synthetic oil to maintain a protective film under high-stress driving conditions.
Always verify your engine type before purchasing your supplies. A quick look at your trunk badge or the eighth digit of your VIN can confirm if you have the standard GDI engine or the turbocharged EcoBoost variant.
Understanding Ford Specification WSS-M2C945-A
It is not enough to just grab any bottle of 5W-20 off the shelf. Ford specifies a very particular set of chemical properties known as WSS-M2C945-A (which has since been updated by newer standards like WSS-M2C960-A1).
This specification ensures the oil contains the necessary detergents and anti-wear additives to protect the Ti-VCT system. The variable cam timing relies on oil pressure to move the camshafts, and incorrect oil can lead to “sludging” that clogs the small oil passages.
If these passages become restricted, you may experience a check engine light with codes related to timing over-advanced or over-retarded. Using oil that meets Ford’s specific standards is the best insurance against these costly electronic and mechanical failures.
Most modern full synthetic oils from reputable brands like Mobil 1, Pennzoil, or Castrol will meet or exceed these Ford requirements. Always check the back of the bottle for the specific Ford “WSS” certification number before buying.
The Role of Synthetic Blend vs. Full Synthetic
Ford originally filled these cars with Motorcraft Synthetic Blend from the factory. This is a high-quality “middle ground” oil that offers better protection than conventional oil but at a lower price point than full synthetic.
If you are a high-mileage driver or live in an area with extreme temperature swings, I highly recommend upgrading to a full synthetic oil. Full synthetics resist thermal breakdown much better and keep the internal components of your GDI (Gasoline Direct Injection) engine cleaner over time.
GDI engines are notorious for carbon buildup on the intake valves. While oil doesn’t touch the valves directly in a GDI setup, high-quality synthetic oils have lower volatility, meaning less oil vapor is sucked through the PCV system to create those deposits.
Oil Capacity and Filter Requirements
Knowing what oil does a 2013 ford focus take also involves knowing exactly how much to buy. There is nothing worse than being half a quart short while your car is up on jack stands.
For the 2.0L non-turbo engine, the capacity is 4.5 quarts (4.3 liters). I usually recommend buying a 5-quart jug; this gives you the full amount needed and leaves you with half a quart for future “top-offs” between service intervals.
The Focus ST (2.0L EcoBoost) requires significantly more, coming in at 5.7 quarts (5.4 liters). Owners of the ST model should purchase one 5-quart jug and an additional single quart to ensure the level reaches the “full” mark on the dipstick.
Choosing the Right Oil Filter
The oil filter is just as critical as the oil itself. For the 2013 Ford Focus, the standard Motorcraft part number is FL-910S. This filter features a silicone anti-drainback valve, which prevents oil from draining out of the upper engine when the car is off.
Using a cheap, generic filter often results in “dry starts,” where the engine runs for a few seconds without oil pressure. Over hundreds of starts, this causes unnecessary wear on the rod bearings and camshaft journals.
If you prefer aftermarket brands, the Wix 51315 or the Mobil 1 M1-102A are excellent high-efficiency alternatives. These filters offer superior filtration media that can trap smaller contaminants compared to budget-tier options.
Step-by-Step DIY Oil Change Guide
Performing your own oil change is a great way to bond with your vehicle and ensure the job is done right. Before you start, gather your 15mm socket, an oil filter wrench, a drain pan, and a funnel.
- Warm the Engine: Run the car for about five minutes. Warm oil flows faster and carries more contaminants out of the engine than cold, thick oil.
- Lift the Vehicle: Use a floor jack and jack stands or a set of sturdy ramps. Never work under a car supported only by a hydraulic jack.
- Remove the Underbody Cover: The 2013 Focus features a plastic “aeroshield” held in place by several T30 Torx screws. Carefully remove this to access the oil pan.
- Drain the Oil: Place your pan under the 15mm drain plug. Loosen it slowly, and be prepared for the flow. Let it drain until it is just a slow drip.
- Replace the Filter: Move the pan under the oil filter. Unscrew the old filter (careful, it will be full of hot oil). Wipe the mounting surface clean and lubricate the new filter’s rubber gasket with a dab of fresh oil.
- Reinstall the Plug: Put the drain plug back in and tighten it to 20 lb-ft. Do not overtighten, as the oil pan is made of aluminum and can strip easily.
Once everything is buttoned up underneath, pour in your 4.5 quarts (or 5.7 for the ST) and start the engine. Check for leaks, reinstall the aeroshield, and you are ready to roll.
Resetting the Oil Life Monitor
The 2013 Ford Focus features an Intelligent Oil-Life Monitor (IOLM) that needs to be reset after every service. It is a simple process that doesn’t require any special tools or scanners.
With the driver’s door closed, turn the ignition to the “On” position but do not start the engine. Simultaneously press and hold both the accelerator and brake pedals for about 20 seconds.
A message will appear on the instrument cluster saying “Oil Reset in Progress,” followed by “Oil Reset Complete.” Once you see that message, you can release the pedals and turn the ignition off. Your car now knows it has fresh lifeblood.
Common Oil Issues in the 2013 Ford Focus
While the 2.0L engine is generally robust, there are a few things to watch out for as the car ages. One common issue is a leaking valve cover gasket, which can allow oil to seep into the spark plug wells, causing misfires.
Another area to monitor is the oil filter housing. If you notice oil spots on your driveway after a change, ensure the old gasket from the previous filter didn’t get stuck to the engine block—a common mistake known as “double-gasketing.”
If you own an early-build 2013 model, keep an eye on the oil pressure switch located near the filter. These have been known to leak internally through the electrical connector, which can actually “wick” oil up into the wiring harness over time.
Regularly checking your dipstick once every two weeks is the best way to catch these issues early. A 2013 Focus should not consume a significant amount of oil between changes, so any drop in level should be investigated by a professional.
Synthetic vs. Synthetic Blend: Which is Better?
In the debate over what oil does a 2013 ford focus take, the choice between blend and full synthetic often comes down to budget versus protection. While the manual says synthetic blend is “fine,” full synthetic is objectively “better.”
Full synthetic oils are engineered at the molecular level to be uniform. This means they provide a more consistent lubricating film and are much less likely to oxidize (turn into sludge) when the engine gets hot in stop-and-go traffic.
If you plan on keeping your Focus for another 100,000 miles, the extra $10 to $15 per oil change for full synthetic is a wise investment. It keeps the VVT solenoids clean and ensures the timing chain stays properly lubricated, preventing “chain stretch.”
For those who drive in extreme cold, such as the northern US or Canada, full synthetic 5W-20 is almost a necessity. It stays fluid at temperatures where synthetic blends begin to turn into a gel-like consistency, protecting your engine during those crucial first seconds of a cold start.
Frequently Asked Questions About 2013 Ford Focus Oil
How often should I change the oil in my 2013 Ford Focus?
Ford recommends an interval of 7,500 to 10,000 miles under “normal” driving conditions. However, if you do a lot of city driving, idling, or live in a dusty environment, I strongly suggest changing it every 5,000 miles to prevent carbon buildup.
Can I use 5W-30 in my standard 2.0L Focus?
While it won’t cause immediate engine failure, it is not recommended for the standard Ti-VCT engine. The variable timing system is calibrated for the flow rate of 5W-20. Using a thicker oil can lead to slightly reduced fuel economy and potential timing errors in very cold weather.
Does the 2013 Ford Focus have an oil life light?
Yes, it features a message center alert that will display “Engine Oil Change Soon” or “Oil Change Required.” This system calculates oil life based on engine revolutions, temperature, and driving habits rather than just a simple mileage countdown.
What happens if I overfill the oil?
Overfilling can lead to “foaming,” where the crankshaft hits the oil in the pan and whips air into it. Aerated oil does not lubricate well and can lead to oil starvation at high RPMs. If you are more than half a quart over the “Max” line, you should drain the excess.
Closing Thoughts for the DIY Mechanic
Taking care of your 2013 Ford Focus doesn’t have to be a daunting task. By understanding exactly what oil does a 2013 ford focus take and following a disciplined maintenance schedule, you are protecting one of your most important assets.
Remember to always prioritize safety when working under your vehicle. Use the right tools, double-check your drain plug tightness, and never skip the underbody aeroshield, as it helps with both fuel economy and protecting your engine from road debris.
A well-maintained Focus is a reliable, fun-to-drive car that can serve you for many years. Keep that oil clean, listen to your engine, and don’t be afraid to get your hands a little dirty. Stay safe and stay on the road!
