Purolator Hid an Oven Mitt in an Engine to Sell Car Filters
Purolator's 2016 hidden camera prank, titled "You Found What in My Engine?", is an experiential and social video campaign created by agency Gelia in which an actor posing as a mechanic presents real, unsuspecting automotive repair shop customers with absurd objects — including an oven mitt, a dog bone, circus peanuts, a fictional "Pomeranian Clamp," and a "stalagmite flush" — supposedly discovered inside their vehicles, capturing their genuine reactions on hidden cameras.
The campaign launched in December 2016 and was produced in Buffalo, New York, where a real automotive repair shop served as the stage. Purolator, operating as MANN+HUMMEL Purolator Filters LLC, deployed the stunt to reinforce a simple but durable brand message: drivers should remain vigilant about vehicle maintenance, and nothing should slip past them when caring for their cars. The format translated that message into entertainment, delivering it through a social media video series distributed across the United States.
The campaign carries a Clapboard Score of 58 out of 100, reflecting a concept with genuine comedic originality and strong social shareability, balanced against limited documented reach data and a relatively contained production scale. For the automotive filters category — a market in which brand differentiation is notoriously difficult to achieve through conventional advertising — the hidden camera prank format offered Purolator a rare opportunity to build emotional connection and brand recall without relying on technical product claims. The United States remained the sole documented geographic market for the activation.
Purolator operates in a category where most consumers make purchasing decisions with low engagement and limited brand loyalty. Automotive filters are considered a commodity by many drivers across the United States, purchased primarily on price or installer recommendation rather than brand affinity. This dynamic creates a strategic challenge for any filter brand: conventional product advertising struggles to break through, because the product itself generates little inherent excitement at the point of consideration.
The hidden camera prank format addresses this problem directly. By using humor and genuine human surprise, the campaign creates emotional resonance that a technical comparison advertisement cannot replicate. The absurdity of the scenario — a mechanic solemnly presenting circus peanuts as a discovered engine component — anchors the core message in a memorable, shareable moment rather than a forgettable product claim. Tina Davis, Senior Marketing Manager at MANN+HUMMEL Purolator Filters LLC, stated in Work Truck Online on December 14, 2016, that "the hidden camera stunt was a fun way to remind drivers to let nothing get by them when it comes to taking proper care of their vehicles."
The strategic timing also carried commercial logic. According to a report from visiongain.com, the global automotive filters market was projected to reach approximately US$18 billion by 2025 as of a 2017 analysis — a figure that underlines the competitive intensity facing individual brands in this space. In 2016, as reported by fleetmaintenance.com, MANN+HUMMEL acquired both WIX Filters and Purolator, bringing two significant aftermarket brands under a single ownership group and intensifying the internal rationale for Purolator to establish a distinctive consumer-facing identity in the United States. In a crowded aftermarket environment, earned social media views represented a cost-efficient path to brand visibility.
Gelia executed the campaign at an automotive repair shop in the Buffalo, New York area, using hidden cameras to capture the unscripted reactions of real customers. The creative conceits were specific and deliberately escalating in absurdity. An actor playing the role of a mechanic approached customers with a straight-faced delivery, informing them that an oven mitt, a dog bone, or circus peanuts had been retrieved from their engine compartment. The fictional diagnoses — including the "Pomeranian Clamp" and the "stalagmite flush" — were presented with the same clinical seriousness as a genuine repair consultation, creating a comic tension between the mechanic's manner and the evident nonsense of his findings.
The production required precise casting and performance discipline. The actor portraying the mechanic had to sustain credibility long enough for each customer's reaction to unfold naturally, without breaking the illusion. The resulting footage, edited into a social media video series, preserved the authenticity that makes hidden camera content effective: the customers' confusion, disbelief, and eventual laughter are unperformed and unscripted, giving the brand communication a human texture that scripted advertising rarely achieves.
The creative team at Gelia responsible for the campaign included Creative Director Bill Paterson, Art Directors Jason Pautler and Jason Yates, and Copywriters Kerri Linsenbigler and Jennifer Ferris. The combination of a simple, repeatable format with strong comedic writing — particularly in the invention of plausible-sounding nonsense terminology — reflects a disciplined creative approach to a brief that could easily have produced a more generic execution. The campaign contains one documented media asset, consistent with a focused social distribution strategy rather than a broad multi-platform rollout.
No independently verified performance data beyond video views for the "You Found What in My Engine?" campaign is publicly available through sources outside the agency's own reporting. According to gelia.com, the campaign generated more than 1.8 million video views — a meaningful figure for a single-asset social video activation in the automotive filters category, particularly one produced by a regional agency for a product with limited mass-market advertising history.
No award recognition for this campaign is publicly verified in available sources. Structural analysis of the campaign suggests several factors that likely contributed to its organic traction in the United States. Hidden camera prank content carries inherent shareability because it delivers genuine, unscripted emotional response — a format that social media algorithms across platforms have consistently rewarded since the early years of digital video distribution. The specificity of the absurd objects, combined with the professional context of an automotive repair shop, made the content surprising and category-relevant simultaneously, two qualities that strengthen both initial engagement and repeat sharing.
The campaign's primary limitation, from a measurable impact standpoint, is the absence of documented conversion data, brand-lift studies, or sales attribution linking the video views to filter purchases. As an experiential and social video activation, its value resided principally in awareness and brand sentiment rather than direct response — a trade-off that is structurally appropriate for a brand attempting to build differentiated identity in a low-engagement category across the competitive United States aftermarket.

The Purolator prank mechanic told customers he had found an oven mitt, a dog bone, and circus peanuts in their engine compartments. Fictional diagnoses such as the "Pomeranian Clamp" and "stalagmite flush" were also delivered with straight-faced seriousness, amplifying the comedic contrast between the mechanic's professional manner and the nonsensical findings.
Purolator used a hidden camera prank to cut through the low-engagement nature of the automotive filters category. As Tina Davis of MANN+HUMMEL Purolator Filters LLC stated in Work Truck Online, the stunt reminded drivers to let nothing slip by in vehicle care — framing a routine maintenance message in a genuinely entertaining, shareable format suited to social media distribution.
The Purolator hidden camera prank was filmed at an automotive repair shop in the Buffalo, New York area. Buffalo is also the home city of agency Gelia, which created the campaign. The United States was the sole documented geographic market for the December 2016 activation, which was produced as a social video series.
