Oil filters don’t get nearly the attention motor oil does—but they should. A weak filter can let metal shavings, carbon sludge, and dirt circulate freely through your engine. Over time, that means accelerated wear, noisy starts, and potentially even damage to internal components.
Fram is one of the most recognizable names on the shelf. But if you’ve been around car forums or talked to a few shop techs, you’ve probably heard some strong opinions—many of them not too flattering. So, where does the truth lie? Let’s break it down.
A Brand with a Controversial Reputation
Fram has been around for decades. It was originally part of Allied Signal, which was later acquired by Honeywell. These days, Fram is operated by Trico Group under the name Autolite IP Holdings.
They offer several product lines, from bargain-bin filters to high-end synthetic-ready options. And that’s where the problems start—not all Fram filters are created equal.
1. Cardboard End Caps Raise Eyebrows
One of the loudest criticisms aimed at Fram—especially in their Extra Guard line—is their use of fiberboard (often called cardboard) end caps instead of metal.
While Fram insists that their bonding process holds up, many mechanics and teardown reviews call out the material as a weak point. Compared to metal end caps used in filters like WIX or Mobil 1, it just doesn’t inspire the same confidence in long-term durability.
The more premium Fram lines—like Ultra Synthetic—ditch the fiberboard for higher-quality construction, so this issue really depends on which model you’re buying.
2. Anti-Drainback Valve Quality Depends on the Model
The anti-drainback valve (ADBV) plays a critical role in preventing dry starts by keeping oil from draining out of the filter when the engine shuts off. Some older Fram filters and lower-end models used nitrile rubber for this valve, which doesn’t perform well in cold weather and can harden over time.
That leads to dry starts, increased engine wear, and—if you’re paying attention—a noticeable tapping sound when you first fire up the engine. Fram’s Ultra Synthetic filters now use long-lasting silicone valves, putting them on par with much more expensive filters in that department.
3. Media Quality and Filtration Efficiency Vary Widely
Another recurring complaint is about the quality of Fram’s filter media. The pleat spacing, surface area, and general density of the filter material in Extra Guard filters tend to lag behind what you’ll find in brands like Royal Purple or Purolator Boss.
That translates to lower dirt-holding capacity and reduced filtration over longer oil change intervals. But again, it’s a tale of two product lines—Fram Ultra uses dual-layer synthetic media that performs well in third-party efficiency tests and is rated for up to 20,000 miles with synthetic oil.
4. Construction Is a Step Down in Budget Lines
Fram’s more affordable filters often take heat for how they’re built. From thinner bypass valve springs to the absence of metal clips on the media seam, these small shortcuts add up, especially in high-pressure or high-heat conditions.
The filters will generally work fine in basic commuter cars with frequent oil changes, but they’re not built to take abuse. Fram Ultra, on the other hand, has a noticeably more solid design, including a metal core, silicone ADBV, and reinforced media structure.
5. Not a Great Match for High-Flow Oil Systems
Certain vehicles—like performance Subarus or high-output European engines—use high-volume oil pumps that push more oil through the system than basic filters can handle.
Fram’s Extra Guard filters are not the best choice here; they’re more likely to collapse under pressure or go into bypass prematurely. For those setups, a high-flow filter with strong internal components is essential. Fram Ultra is better suited, but still isn’t the first pick for serious performance builds.
So, Should You Avoid Fram?
Not necessarily—but you do need to choose wisely. Fram’s Extra Guard filters are built to hit a price point. They work fine for short oil change intervals and lower-stress engines, but they cut corners in construction, filtration, and durability. If your goal is basic functionality for a budget daily driver, they’ll do the job. Just don’t expect top-tier protection.
✔ Up to 10,000 Miles of Protection – Designed for long-lasting performance with conventional or synthetic motor oils.
✔ Advanced Filtration Media – Cellulose and glass fiber blend captures up to 95% of harmful dirt particles, protecting your engine from wear.
✔ Reliable Engine Protection – Proprietary filter media and silicone anti-drain back valve help maintain consistent oil flow and engine longevity.
✔ Easy Installation & Removal – Features a SureGrip non-slip surface for quick, hassle-free filter changes.
✔ Ideal for Routine Maintenance – Built for everyday drivers who keep up with regular oil change intervals.
Fram’s Ultra Synthetic line is a different story. These filters are well-regarded—even by critics—and stack up competitively against premium brands.
They’re built with synthetic filter media, silicone valves, and solid internal components. If you’re using synthetic oil and want to run longer intervals between changes, the Ultra line is a smart, affordable choice.
✔ Easy, Mess-Free Installation – SureGrip® non-slip surface makes removing and installing your filter a breeze—even with oily hands.
✔ 99%+ Dirt Trapping Efficiency – Dual-layer synthetic media captures fine debris and contaminants for cleaner oil and better engine health.
✔ Extended Life Protection – Built for synthetic oil changes lasting up to 20,000 miles—ideal for high-mileage drivers and long service intervals.
✔ Strong Start-Up Defense – Silicone anti-drainback valve delivers quicker oil pressure on startup and resists breakdown in hot oil environments.
✔ Heat & Pressure Tough – High-temp gasket and durable build stand up to intense engine heat and pressure without leaks or degradation.
The real problem with Fram is that the brand’s older reputation still shadows its current lineup. That reputation was built on budget models and widely shared teardown photos showing flimsy parts. However, Fram has clearly improved its premium offerings in response to the backlash.
If you’re particular about what goes into your engine—and you should be—there are plenty of solid alternatives out there: WIX XP, Royal Purple, Mobil 1, or Bosch Distance Plus. But if you find a good deal on Fram Ultra Synthetic, don’t be so quick to write it off.
