Valvoline Oil Filter VO40: How to Confirm It Fits Your Vehicle
The short answer
VO40 is a part number for a Valvoline-branded oil filter. Whether it is the right filter for you depends on your vehicle's exact model year, market, engine and sometimes trim. Oil filters that look alike can differ in thread size, gasket diameter and internal valves, so a filter that fits one version of a model may not suit another.
This article does not include a verified application list, dimensions or cross-reference numbers for the VO40, because none were available to draw on. Treat any fitment claim you find, including this one, as something to confirm against your own vehicle details before you install the filter.
What the part number does and doesn't tell you
A filter part number identifies one physical design within a brand's catalogue. It does not by itself tell you which vehicles the filter suits. That mapping comes from the manufacturer's application data, which links the part number to specific vehicles and engines.
Because catalogues are revised, a part number's listed applications can change over time. If you are relying on a listing that is several years old, check it against current data.
Details that decide whether an oil filter fits
When you compare the VO40 with your vehicle's requirement, these are the specifications that matter. None of the values below are confirmed for the VO40; they are the points to check.
Thread size and pitch: the diameter and spacing of the threads in the filter's centre hole, which must match the threaded stud on the engine. A mismatch either won't thread on or won't seal safely. Gasket diameter: the rubber seal ring that presses against the engine's mounting surface. It needs to sit fully on that surface to seal. Overall height and outer diameter: the filter has to clear nearby components such as exhaust parts, brackets or the subframe. Bypass valve setting: a spring-loaded valve that lets oil skip the filter element if it becomes clogged or the oil is very thick when cold. The opening pressure is set to suit the engine's oil system. Anti-drain-back valve: a flap, usually rubber, that stops oil draining out of the filter when the engine is off. It matters most on engines where the filter is mounted sideways or upside down. Filter type: the VO40 number refers to a spin-on style filter only if Valvoline's listing says so; some engines use a cartridge element in a housing instead, and the two are not interchangeable.
How to confirm the VO40 is right for your car
Write down your vehicle's model year, make, model, engine size and engine code. The engine code is often more reliable than the engine size alone, since one model can be sold with several engines. Note the market the vehicle was built for. Versions sold in different regions can use different engines or filters under the same model name. Look up the VO40 in Valvoline's current application data or use a parts retailer's vehicle lookup, and check that your exact engine appears, not just your model. Compare against your owner's manual or the filter currently on the engine. If the existing filter is the original-equipment type, its part number gives you a reference to cross-check. If any listing is ambiguous, for example it lists your model but not your engine, ask a parts counter or dealer to confirm using your vehicle identification number.
Gaps to be aware of
No verified information was available here on the VO40's vehicle applications, physical dimensions, thread specification, valve settings, filter media, recommended change interval, price or availability. Nor was any confirmed cross-reference to other brands' part numbers. Rely on the manufacturer's current catalogue or a parts professional for those details rather than on general advice.
Next step
Gather your vehicle's year, market and engine code, then check them against current VO40 application data before buying. If the listing matches your exact engine, the filter is a reasonable candidate. If it only matches your model name, confirm with a parts specialist first.
