Choosing the right oil filter for a 2013 Ford Focus starts with fitment. Ford’s 2013 Focus owner’s guide specifies the Motorcraft FL-910-S oil filter for both the 2.0L GDI and 2.0L GTDI EcoBoost gasoline engines. The two ECOGARD filters below are aftermarket alternatives that ECOGARD catalogs for Ford Focus 2.0L applications from 2005 through 2018.
The main difference is service positioning: the ECOGARD S241 is the synthetic-focused extended-life option, while the ECOGARD X241 is the conventional-filter option for standard service intervals. Your oil, filter, driving conditions, and Ford maintenance guidance should determine the actual change interval.
Important: This guide is for compatible 2013 Ford Focus gasoline models. It does not apply to the Focus Electric, which does not use an engine oil filter.
Quick Verdict
Best for synthetic oil and longer service intervals: ECOGARD S241. ECOGARD rates it for synthetic-oil service up to 10,000 miles when used as directed.
Best for standard oil changes: ECOGARD X241. ECOGARD positions it as a conventional oil filter with protection up to 5,000 miles when used as directed.
Fitment first: Ford specifies FL-910-S for the 2013 Focus 2.0L gasoline engines, so confirm any aftermarket filter against your exact vehicle before installation.

Fitment Note Before You Buy
Ford’s 2013 Focus owner’s guide lists the FL-910-S oil filter for both the 2.0L GDI and 2.0L GTDI EcoBoost gasoline engines. ECOGARD’s current catalog lists both S241 and X241 for Ford Focus 2.0L gasoline applications from 2005 through 2018.
Even with that catalog match, confirm the current Amazon fitment checker, your VIN or exact engine configuration, and your owner’s manual before installing an aftermarket filter. Listings can change, and correct thread, gasket, bypass, and filter dimensions matter.

How We Chose These Oil Filters
We focused on verified catalog fitment, filter type, service positioning, construction details, and clear manufacturer guidance. Because oil-filter fitment is safety- and engine-protection-sensitive, products with conflicting replacement specifications were not included as recommendations.
We also avoided relying on changing star ratings, review counts, exact prices, or unverified buyer-sentiment claims. The goal is to help you compare the two clearly documented ECOGARD options against Ford’s specified FL-910-S filter family.
ECOGARD S241 Oil Filter for Ford Focus
The ECOGARD S241 is the stronger choice if you use synthetic oil and want an extended-life filter option. ECOGARD describes the S241 as a Synthetic+ filter intended for synthetic-oil changes with intervals up to 10,000 miles when used as directed.
Its published specifications include synthetic-blend filter media, 99% efficiency at 25 microns under ISO 4548-12, a silicone anti-drain back valve, a bypass relief valve, and a 3/4″-16UNF-2B thread. ECOGARD also catalogs it for Ford Focus 2.0L gasoline applications from 2005 through 2018.
That does not mean every driver should automatically run a 10,000-mile interval. Follow the shorter limit required by your engine oil, Ford maintenance guidance, driving conditions, or the filter manufacturer.

ECOGARD X241 Premium Spin-On Engine Oil Filter
The ECOGARD X241 is the practical pick for standard maintenance intervals. ECOGARD positions this as its conventional oil-filter option and rates it for engine protection up to 5,000 miles when used as directed.

- Cross-check aftermarket fitment: Confirm the current product listing, your VIN or parts catalog, and the replacement specifications before installation.

FAQ
What Oil Filter Does a 2013 Ford Focus Use?
Ford’s 2013 Focus owner’s guide specifies the Motorcraft FL-910-S oil filter for both the 2.0L GDI and 2.0L GTDI EcoBoost gasoline engines. Aftermarket filters should be cross-checked against that application and your exact vehicle before installation.
Does the ECOGARD S241 Fit a 2013 Ford Focus 2.0L?
ECOGARD’s current catalog lists the S241 for Ford Focus 2.0L gasoline applications from 2005 through 2018, which includes the 2013 model year. Verify the current seller fitment data and your exact vehicle before ordering.
Does the ECOGARD X241 Fit a 2013 Ford Focus 2.0L?
Yes, ECOGARD’s catalog lists the X241 for Ford Focus 2.0L gasoline applications from 2005 through 2018. As with any aftermarket part, confirm your vehicle details before installation.
What Is the Difference Between ECOGARD S241 and X241?
The S241 is ECOGARD’s synthetic-focused extended-life option, with a manufacturer-stated service capability up to 10,000 miles when used as directed. The X241 is the conventional-filter option, with manufacturer-stated protection up to 5,000 miles when used as directed.
The S241 also uses synthetic-blend media and a silicone anti-drain back valve, while the X241 uses conventional-filter media positioning and a nitrile anti-drain back valve.
How Often Should I Change the Oil Filter on My 2013 Ford Focus?
Use Ford’s maintenance guidance and your oil-life information as the primary reference. Do not extend an oil-change interval simply because a filter advertises a higher maximum service capability. Severe driving conditions can require more frequent maintenance.
Can I Use an Aftermarket Oil Filter Instead of Motorcraft FL-910-S?
Aftermarket filters are commonly cross-referenced to the FL-910-S application, but fitment and specifications should be verified carefully. If you want the least ambiguity, use the Ford-specified Motorcraft FL-910-S or a properly verified equivalent.
Final Picks at a Glance
Choose ECOGARD S241 if you use synthetic oil and want the longer service capability of ECOGARD’s Synthetic+ line.
Choose ECOGARD X241 if you follow a standard maintenance schedule and want the simpler conventional-filter option.
Prefer OEM certainty? Ford’s 2013 owner’s guide specifies Motorcraft FL-910-S for both 2.0L gasoline engine variants.
