If you drive a direct-injection engine, oil vapor is silently coating your intake valves with carbon, and that buildup quietly robs you of power and fuel economy. A universal oil catch can sits in your PCV line and traps that oily mist before it ever reaches the intake, and this guide sorts the kits that genuinely do the job from the ones that just look the part.
I’m Mo Maruf — the founder and writer behind GoCarLife. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You’ll see exactly which universal oil catch can fits your budget and engine bay, with real owner experience baked into every pick.
Our Picks at a Glance
How To Choose The Best Universal Oil Catch Can
A catch can is a simple device, but picking the right one depends on three things: how it separates oil inside, how it connects to your engine, and how easy it is to empty.
Baffle or Filter — The Separation Method
An empty can just lets vapor swirl around and some oil condenses on the walls. A baffled can uses internal plates or mesh to force the oil to drop out of the air stream, which catches far more. Some kits add a bronze or stainless filter for even better separation, and a few let you stuff in extra stainless steel wool to boost capture.
Hose Size and Fittings — The Connection
The hose must match your factory PCV line, or you will be hunting for adapters. Common sizes here are 3/8-inch, 1/2-inch, and AN10 (which is about 5/8-inch). The inlet and outlet threads matter too — M16 x 1.5 is common, and AN fittings give you straight, 45-degree, or 90-degree angles to route around obstacles.
Draining and Capacity
Capacity ranges from a small 300 ml to a full 1 liter, and bigger is better on high-mileage or boosted engines that push a lot of vapor. A bottom drain valve means you unscrew a plug and empty it in place; without one, you unbolt the whole can each time. In freezing weather, moisture can collect and freeze, so you will be cleaning it more often in winter.

In‑Depth Reviews
1. EVIL ENERGY Oil Catch Can, 300ML Universal Baffled Catch Can Kit
Our pick — over 4★ from 300+ verified ratings; the strongest balance of quality and price.
The compact pick that nearly disappears in the engine bay for a factory look.
The defining trait here is the 300 ml capacity paired with a removable baffle and low-micron bronze filter — a combination that traps oil and moisture to keep intake valves, pistons, and engine internals clean. The 300 ml tank with baffle and bronze filter fits most engine bays, provided there is clearance for the compact body.
It ships with a 5-foot NBR fuel hose that resists wear and heat, with a 3/8-inch inner diameter and M16 x 1.5 threads on the inlet and outlet. Buyers report it works perfectly on a Golf GTI 2010, looks sharp on an Avalanche, and one person found it eliminated excessive smoke on cold start. The recurring praise centers on build quality — over 40 owners single out the quality and more than 30 mention how well it functions.
There is one honest caveat: the can applies only to the front of the PCV system, not the whole crankcase vent. And in below-freezing weather, the maker notes moisture can build up and freeze, so plan to clean it weekly or reinstall the original PCV hose for winter.
What Owners Love
- Compact size makes install easy and hides well
- Removable baffle plus bronze filter for solid separation
- Complete kit with hose and instructions
Watch Out For
- Small 300 ml tank fills faster on high-mileage engines
- Freezing weather can cause moisture buildup
- Only covers the front of the PCV system
The verdict: For a clean, low-profile install on a daily driver, this is the one to grab.
The trade-off: If your engine pushes heavy vapor, the smaller tank means more frequent draining.
2. EVIL ENERGY 10AN Oil Catch Can 750ml Universal Baffled Breather Filter
The 750 ml workhorse built for high-performance setups, with a drain valve that empties in place.
This one answers the biggest annoyance of catch cans — draining — with a built-in 3/8 NPT bottom valve that lets you empty and reuse the can without removing it. The 750 ml tank uses 10AN fittings (7/8-14 UNF) and pairs with a breather filter, making it big enough for serious builds.
It works with most vehicles as long as there is engine bay space, and the aluminum body with tight-seal fittings is built to avoid leaks. Owners have run it on a drag truck for two years and on a single supercharger setup, with the consistent theme being quality and function at a fair price. The one complaint that surfaces is the drain petcock handle stripping from over-tightening — treat it gently.
Owners consistently praise the value, noting the 10AN threads are compatible with other brands for easy hose swaps.
Why It Wins
- Drain valve means no unbolting to empty
- 750 ml capacity suits boosted engines
- Universal fit with quality aluminum build
The Catch
- Petcock handle can strip if over-tightened
- Fittings sold separately, not included
Reach for this: If you want a large-capacity can that drains cleanly without removal.
Look elsewhere: If you want a plug-and-play kit with fittings in the box.
3. Universal 10AN Oil Catch Can Tank Baffled 1L with Filter Aluminum Black HTRACING
The full-liter tank with proper internal baffling that handles high boost without overflowing.
This is the biggest can on the list, holding a full 1 liter, which makes it the right call for engines that generate serious crankcase vapor. It is made from T-6061 aluminum with TIG welds and a matte surface, built to resist high temperature and pressure without leaking.
The bottom drain valve makes cleaning easy and the can is fully reusable. It fits cars and trucks and is designed for gasoline engines. The standout owner story is a high-boost 12-valve Cummins, where the verdict was that the proper internal baffling actually works as it should — unlike smaller, cheaper cans.
What wins people over is the build quality and the price, with one owner noting it is way cheaper than a Moroso while being well made. The top baffle only fits one 10AN line, and the 1-liter body is bulky, so measure your bay before buying.
Solid and honest: For a boosted truck pushing big vapor, this 1-liter tank with real baffling is the pick that earns its keep.
Size caveat: Make room for it — it is big, and the top baffle only suits a single 10AN line.
Best for: High-boost diesel and gas builds that need maximum capacity.
Not for: Tight engine bays where a smaller can fits better.
4. 10AN 750ML Oil Catch Can Kit with Drain Valve
The everything-in-the-box kit with angle fittings that route around any obstacle.
This 750 ml can from RYANSTAR RACING stands out because the kit includes a 10-foot AN10 nylon braided CPE hose rated for 500 psi working pressure and 2000 psi burst, plus fittings in 0-degree, 45-degree, and 90-degree angles. That flexibility means you can route the hoses cleanly no matter where your PCV ports sit.
The tank is T-6061 aluminum, anodized black, with a 76mm (3-inch) diameter and an internal baffle system. You can add stainless steel wool inside for even better oil capture, and the bottom drain plug makes emptying simple. It works with coolant, diesel, oil, hydraulic fluid, and air, though it is not compatible with E85 fuel.
Owners find it easy to mount, with one calling it the best bang for the buck and appreciating the fitting variety. The mixed feedback is on the AN fittings — some arrive poorly assembled and one needed fitting broke, so check yours before install. A pair run on an LS build did not catch much, so this one is better suited to a single clean install.
The Kit Advantage
- 10FT braided hose rated to 500 psi working pressure
- Three fitting angles for flexible routing
- 750 ml capacity with easy drain plug
Check Before Install
- Some AN fittings arrive poorly assembled
- One owner found little oil captured on a twin LS setup
Pick this if: You want a full hose-and-fitting kit ready to route day one.
Skip if: You are running a complex dual-can setup that needs flawless fittings from the start.
5. 10AN Oil Catch Can, 750ml Universal Baffled Catch Can and 10AN 5/8 Fuel Line Fitting Kit
The affordable kit that delivers name-brand-level quality without the badge markup.
This BAGARAATAN kit brings a 750 ml capacity with 2 x AN10 inlet and outlet ports vertically aligned on the same side, anodized black. The included 10-foot AN10 CPE hose is rated for 500 psi working pressure and 2000 psi burst, and the fitting set covers 0-degree, 45-degree, and 90-degree angles.
The brass drain valves are tapered, so the more you turn them the tighter they seal, protecting against leaks. The T-6061 aluminum tank is TIG welded, and the internal baffle system keeps oil from escaping — you can also add stainless steel wool to catch more. Owners running turbo setups report it functions exactly as intended, and the phrase “best bang for your buck” comes up repeatedly.
Reviews split on thread quality—some install cleanly, others arrive with damaged threads—so inspect fittings before mounting. This is a value play — expect to inspect threads and possibly swap a fitting.
Value read: You get a full kit — can, braided hose, and angle fittings — at a price that undercuts big brands.
The risk: Quality control varies, so check the threads and fittings before you commit the install.
Reach for it: If budget matters most and you are comfortable double-checking fittings.
Pay more if: You want guaranteed thread quality from the start.
6. 10AN Oil Catch Can 750ML & 10FT Braided 10AN Fuel Line Kit
The 750 ml kit built for modified engines, LS swaps, and performance builds that demand reliability.
This VVORHSBELL setup pairs a 750 ml baffled catch can with a 10-foot AN10 nylon braided CPE hose rated for 500 psi working and 2000 psi burst pressure. The fittings come in 0-degree, 45-degree, and 90-degree angles from T-6061 anodized aluminum, letting you route tight engine bays cleanly.
The tank is 76mm (3 inches) in diameter with a proper internal baffle, and you can add stainless steel wool for extra capture. It works with coolant, diesel, oil, hydraulic fluid, pump gas, and air, but it is not for E85, and the maker notes the hose life shortens when used with fuel. It fits cars and motorcycles, including transmission cooler and turbo oil return systems.
Owners mention it works well on their cars, with one person building a catch can for their side-by-side at a fraction of the cost. Customers note reliable oil capture, and the 750 ml capacity suits most performance engines without being oversized.
Build Highlights
- Tri-angle fittings for flexible routing
- 750 ml capacity suits most performance engines
- Works with cars and motorcycles
Limits
- Not compatible with E85 fuel
- Hose life shrinks when running fuel through it
The fit: A solid all-rounder for LS swaps and modified engines that want a complete, reliable kit.
Not the one: If you run E85, look at a can rated for ethanol.
7. Dorman 46110 Oil Catch Can System – Universal
The U.S.-designed catch can that saves you from pricey carbon-cleaning services.
This Dorman unit is pitched as an OE fix — a way to cut the frequency of expensive intake-valve carbon cleaning services and protect engine compression and fuel efficiency. It comes with everything for a fast install, including two versatile mounting brackets that place it on a wide range of vehicles.
The exterior is ready to paint if you want to match your engine bay. Owners have installed it on a 13 Ram 5.7 with a 90-degree bracket on the filter box, a 2015 Ram Hemi (drilling two holes in the air box and running hoses easily), and a 2010 F150 5.4L — the last needing extra parts like a 5/8-to-15/32 reducer plus the Dorman 46136 PCV hose kit.
The honest catch: on a 2018 Hyundai Sonata GDI, it captured almost nothing after 500 to 1000 miles, and one Durango owner found the supplied hose would not connect to the intake port, needing a longer run. It is a quality kit, but “universal” means you may need a few extra pieces for your specific vehicle.
Smart buy: Designed and backed in the U.S., this is the pick when you want a reliable can that protects your intake from carbon.
Plan ahead: Some installs need extra hoses or reducers, so budget for a small trip to the parts store.
Choose this: For a clean, OE-minded install with brackets that adapt to most vehicles.
Be ready: On some engines, the included hose will not reach the intake port without extra pieces.
8. Mishimoto MMBCC-CBTWO-XLBK XL Baffled Oil Catch Can, 2-Port
The premium 2-port can with a 50 micron bronze filter and a lifetime warranty.
This Mishimoto XL separates oil particles from PCV/CCV air using a 50 micron bronze filter inside a patent-pending billet 6061 aluminum body sealed with Viton O-Rings. That filter grade is finer than most, which means it catches smaller oil droplets before they reach your intake.
It holds a 7.5 fluid-ounce internal capacity with a 3/8-inch NPT drain plug, and the inlet and outlet are M16 x 1.5 threaded. The kit includes two CNC-machined aluminum 1/2-inch barbed hose fittings, a universal mounting bracket, and self-tapping screws — though the bracket is the weak point, with one owner saying you will have to cobble your own mounting solution at this price.
The billet aluminum body and Viton seals handle heat and pressure reliably, outlasting budget alternatives. But the same filter that catches everything can freeze in sub-zero short-trip driving, blocking airflow — treat winter use with care. The lifetime warranty backs the premium build, signaling long-term durability.
Premium Perks
- 50 micron bronze filter for fine oil capture
- Billet 6061 aluminum with Viton O-Rings
- Lifetime warranty backs the build
Premium Quirks
- Mounting bracket is underwhelming for the price
- Filter can freeze in sub-zero short trips
The pick for: Enthusiasts who want a finely-filtering can from a trusted brand and never want to buy again.
Reconsider if: You live in a deep-freeze climate and make lots of short trips.
9. Moroso 85497 Air/Oil Separator Catch Can Kit, Vehicle-Specific Small Body
The compact billet can with internal baffling and mesh, built in the USA for clean intake air.
One important fit note: Amazon lists this Moroso as a vehicle-specific fit, not universal — so check the fitment tool before ordering.
This Moroso plumb into your PCV system to capture excess crankcase vapors, residual oil mist, and moisture before they reenter the intake tract — and the payoff is cleaner intake air and better engine performance. The billet aluminum body has internal baffling and mesh media, so the separation happens inside the can itself.
At a compact size, it fits tight spots, and the two-piece body unscrews for draining — a simple no-valve design. The polished body can be chromed, painted, or powder coated for a custom look, and it includes clamp, fittings, hardware, hoses, and the tank. Owners run it on a 2022 Toyota Camry TRD and report it catches excess vapors within the first 50 miles, with a dry intake manifold as the result.
The billet body is durable, but the included bracket and screws are flimsy—one owner mounted the can directly to the fender instead. At this price, expect to supply your own mounting solution.
Quality first: Made-in-USA billet with internal baffling and mesh — this is the compact can that keeps intakes dry.
The weak link: The included bracket and screws do not match the can’s quality; plan to mount it your own way.
Go with this: For a compact, high-quality separator that protects your intake and fits tight engine bays.
Pass on it: If you want a drain valve and a sturdy bracket in the box.
Understanding the Specs
Baffle vs Filter
A baffle is a set of internal plates that force oil vapor to slow down and condense into liquid, which then pools in the bottom of the can. Some cans add a bronze filter (like a 50 micron element) or let you stuff in stainless steel wool to catch even more mist. A can with neither is just a catch jar — it collects some oil but lets a lot of vapor slip through.
Hose Size and Fittings
The hose internal diameter must match your factory PCV line for a clean connection. Common sizes are 3/8-inch, 1/2-inch, and AN10 (roughly 5/8-inch). Threads matter too: M16 x 1.5 is a standard port thread, while AN fittings come in 0-degree, 45-degree, and 90-degree angles so you can route around other engine parts. Getting the right size avoids leak-prone adapters.
Drain Valve
A bottom drain valve means you unscrew a plug or petcock and empty the can in place — no unbolting. On cans without one, you remove the whole unit to pour it out. In freezing weather, moisture can collect and ice up, so a can you can drain quickly matters more in winter. Capacity ranges from 300 ml to 1 liter; bigger tanks mean fewer drain intervals on high-mileage or boosted engines.
Warranty and Build
Machined 6061 aluminum with TIG welding is the durable standard, resisting heat and pressure without leaking. Warranty terms vary — some kits carry a 1-year or 90-day warranty, while premium brands offer a lifetime warranty. If your engine runs E85, check compatibility, because some hoses and seals degrade faster on ethanol.
