The Fram 4967 is a spin-on oil filter that fits specific Ford, Lincoln, and Mercury vehicles from the 1980s through early 2000s
The Fram 4967 is a spin-on oil filter — the kind you twist off and twist back on by hand, without tools. It has a 3/4-inch-16 thread size, which is the standard connection point on many older domestic vehicles. This filter is designed to remove dirt, metal particles, and sludge from your engine oil as it circulates.
Fram is one of the largest oil filter manufacturers in North America. The 4967 model number appears in their standard-duty line, meaning it is built for regular driving rather than heavy towing or racing. If you own a Ford, Lincoln, or Mercury vehicle from roughly 1980 to 2005, there is a reasonable chance this filter will fit your engine — but you need to verify the exact year, make, and model before you buy, because engine variations within a single model year can use different filters.
Key Takeaways
- The Fram 4967 is a spin-on filter with a 3/4-inch-16 thread that fits many Ford, Lincoln, and Mercury engines, but you must confirm compatibility with your specific vehicle before purchasing.
- Spin-on filters like the 4967 are replaced as a complete unit during an oil change, not cleaned or refilled.
- The filter's micron rating — typically 20 microns for standard-duty Fram filters — determines how small the particles it catches are, which affects both engine protection and oil flow.
- You can cross-reference the 4967 to other brands using online filter databases or by calling a parts store with your vehicle's year, make, model, and engine size.
How to confirm the Fram 4967 fits your vehicle
The safest way to verify compatibility is to look up your vehicle in an online filter database. Fram's website has a "Find a Filter" tool where you enter your vehicle year, make, model, and engine size, and it returns the correct filter number. AutoZone, O'Reilly, NAPA, and Advance Auto Parts all have similar lookup tools on their websites — you can search by vehicle or by filter number to see which vehicles use the 4967.
If you already have a filter in your engine, you can remove it and read the number printed on the side. If that number is 4967, you have confirmation. If you are buying a used vehicle or do not have access to the old filter, call a local parts store with your vehicle's year, make, model, and engine displacement (for example, "1995 Ford F-150 5.0L"). They can tell you in seconds whether the 4967 is correct.
Do not assume that because a filter fits your vehicle's thread size it is the correct one. Thread size is only one specification. The filter's overall diameter, height, and internal bypass valve setting also matter. Using the wrong filter can restrict oil flow or allow unfiltered oil to bypass the media, both of which damage the engine over time.
What the Fram 4967 specification sheet tells you
The Fram 4967 is rated for a 20-micron filtration level, which is standard for passenger-car oil filters. A micron is one millionth of a meter — to put it in perspective, a human hair is roughly 75 microns wide. A 20-micron filter catches particles smaller than that but larger than 20 microns. This is fine for normal engine wear, but it does not catch the smallest contaminants that form in extreme heat or extended drain intervals.
The filter has a bypass valve set to open at approximately 10 pounds per square inch (psi) of pressure difference. This valve protects the engine if the filter becomes clogged — instead of starving the engine of oil, the valve opens and lets unfiltered oil flow through. This is a safety feature, not a sign the filter is working poorly. If your bypass valve opens regularly, it usually means you are going too long between oil changes.
Fram publishes the filter's flow rate (how many gallons per minute can pass through at operating temperature) and its dirt-holding capacity (how many grams of test dust it can trap before the bypass opens). These numbers are useful if you are comparing the 4967 to other filters, but for most drivers, knowing the micron rating and thread size is enough.
Fram 4967 versus other filter brands and models
The Fram 4967 is a mid-range filter. Fram also makes the XG series (extended-drain, designed for synthetic oil) and the Ultra Synthetic line, both of which filter finer particles and last longer. If your vehicle uses the 4967 thread size but you want a longer-lasting filter, you can cross-reference to see which Fram synthetic models fit the same thread.
Other manufacturers make filters that fit the same 3/4-inch-16 thread. Motorcraft (Ford's own brand), Purolator, Bosch, and Wix all produce filters for the same vehicles. You can find cross-reference charts online by searching "[filter number] cross reference" — for example, "Fram 4967 cross reference" will show you which Motorcraft, Purolator, and other brand filters are equivalent. The cross-reference tells you which filters have the same thread, micron rating, and bypass pressure, so you can swap brands without changing how your engine runs.
Price varies by brand and retailer. The Fram 4967 typically costs between $5 and $12, depending on where you buy it. Synthetic or extended-drain filters cost more but last longer, so the per-mile cost may be lower even though the upfront price is higher.
How to install the Fram 4967
Installation is straightforward and requires no special tools beyond a filter wrench (a metal band or socket-style tool that grips the filter's outer shell). Locate the filter on your engine — it is usually mounted vertically on the side or top of the engine block. Slide the filter wrench around the filter and turn counterclockwise to loosen it, then unscrew it by hand.
Before you install the new filter, wipe the mounting surface on the engine block with a clean rag to remove old oil and debris. explore a thin coat of new oil to the rubber gasket on the new filter's top — this helps create a watertight seal and makes removal easier next time. Screw the new filter on by hand until the gasket contacts the mounting surface, then turn it an additional three-quarter turn. Do not use the filter wrench to tighten — hand-tight is correct.
After installation, start the engine and let it run for a minute, then turn it off and wait five minutes. Check the oil level on the dipstick and top it off if needed. The new filter holds a small amount of oil, so the level may drop slightly after the first run.
When to replace the Fram 4967
The Fram 4967 should be replaced at the interval recommended in your vehicle's owner manual — typically every 3,000 to 5,000 miles for conventional oil, or every 7,500 to 10,000 miles for synthetic oil. If you drive in severe conditions (frequent short trips, towing, dusty environments), replace it at the shorter interval. If you drive mostly highway miles with long intervals between starts, you can stretch toward the longer interval.
Some vehicles have a dashboard oil-change reminder light. This light is based on mileage and driving patterns, not on the filter's actual condition. The light is a reasonable guide, but the owner manual is the final authority. If the manual says 5,000 miles and the light comes on at 4,500, follow the manual.
Do not reuse an old filter or attempt to clean it. Spin-on filters are designed to be replaced as a complete unit. The internal media cannot be effectively cleaned, and the bypass valve loses its calibration over time.
Frequently Asked Questions
Can I use a Fram 4967 if my vehicle manual lists a different filter number?
No. The filter number in your manual is specific to your engine's oil flow rate, bypass valve setting, and mounting location. Using a different number can restrict oil flow or cause the bypass valve to open at the wrong pressure. Always follow the manual or have a parts store confirm the correct filter for your vehicle.
What does the rubber gasket on top of the filter do?
The gasket seals the filter to the engine block and prevents oil from leaking around the connection. When you tighten the filter by hand, the gasket compresses and creates a watertight fit. If you over-tighten with a wrench, you can damage the gasket and cause leaks. Hand-tight plus three-quarter turn is the correct installation method.
Is the Fram 4967 the same as a Fram PH4967?
No. The PH prefix indicates a different filter line with different specifications. Always use the exact model number from your manual or parts lookup. If you are unsure, call a parts store with your vehicle information and ask them to confirm the correct number.
Can I use the Fram 4967 with synthetic oil?
Yes, the 4967 is compatible with conventional, blend, and synthetic oils. However, if you use synthetic oil, Fram makes extended-drain filters (like the XG series) designed to last longer with synthetic. These filters cost more upfront but may be more economical over time because you replace them less often.
Where can I dispose of the old filter after I remove it?
Most auto parts stores accept used oil filters for free, even if you did not buy the replacement from them. Some recycling centers also accept them. Do not throw a used filter in the trash — it still contains oil and is considered hazardous waste in most areas. Drain as much oil as possible from the old filter into a drain pan before taking it to a store or recycling center.
