Purolator BOSS PBL14006 Spin-On Oil Filter (SmartFUSION Full Synthetic)

Purolator lists 70+ applications for PBL14006 on the Amazon listing, concentrated on GM small-block V8 platforms. Highest-volume fitments: Chevrolet Silverado 1500 (2003–2006), Tahoe (2000–2006), Suburban 1500 (2003–2006), Corvette (1997–2006), Avalanche 1500 (2003–2006); GMC Sierra 1500 (2001–2006), Yukon (2003–2006), Yukon XL (2003–2006); Cadillac Escalade (2003–2006); HUMMER H2 (2003–2006); plus Buick, Pontiac (Firebird, GTO, Grand Prix), Oldsmobile, Isuzu, and Saab applications. Confirm exact fitment using your year/make/model/engine in Purolator's part finder or Amazon Confirmed Fit before installation.

Its retail price sits below Amazon's standalone-purchase threshold for certain low-priced items, so Amazon flags it as an add-on. To buy it alone you either need a qualifying-order minimum in the same cart or you can enroll the item in Subscribe & Save. Standalone one-click purchase without other items in the cart is not available.

Purolator's own marketing on the Amazon listing is inconsistent: the lead feature bullet says 'up to 20,000 miles' and the product description paragraph says 'up to 15,000 miles.' The conservative 15,000-mile figure is used in this review because it is the lower of Purolator's own two numbers. No independent community long-drain cut-open of PBL14006 has been located to corroborate either claim — the extended-drain rating in the CCT quality score is capped at the standard tier accordingly.

No. Purolator's marketing on the Amazon listing reads 'over 99% Dirt Removal Power' without citing a test standard (no SAE J1858, no ISO 16889), without a micron threshold, and without a beta ratio. For comparison, a SAE J1858 result of β15(c) ≥ 200 — the standard used to verify premium filter efficiency — has not been publicly documented for PBL14006. The CCT filtration_efficiency dimension is scored conservatively for that reason.

Yes — Purolator's feature bullets state a silicone ADBV: 'Silicone anti-drainback valve protects against dry starts.' Silicone is the higher-quality material in this category (more durable than nitrile at high temperatures). The presence of the ADBV is confirmed from manufacturer materials; it has not been independently corroborated by a published cut-open of PBL14006 in the reviewed evidence base.

The PBL14006 gasket is ethylene acrylic — Purolator's 'PuroSEAL' branding — per the Amazon feature bullets. Ethylene acrylic is a synthetic elastomer, not natural rubber. There is no latex allergen pathway for this product.
